Many plants, especially horticultural and garden varieties, are propagated through cuttings; by the use of new techniques, many other plants formerly not susceptible to propagation through cuttings have more successfully reproduced. The plants that develop from cuttings are clones.
Explanation:The cutting method is a technique of vegetative reproduction in plants. In this method, a branch of the stem is cut out from the plant and buried in the soil. New leaves arise from the nodes in the stem and the new roots also develop giving rise to a whole new plant. Example- rose, sugarcane. Cuttings can be made from any part of the plant. Most frequently, however, either a stem or leaf is used. A stem cutting includes a piece of stem plus any attached leaves or buds. Thus, stem cutting only needs to form new roots to be a complete, independent plant. A cutting is a section of plants such as a modified stem, leaf, or root used for vegetative propagation that forms either adventitious shoots, adventitious roots (stem and single node cuttings), or both (root and leaf cuttings). These are long pieces of roots which are used to artificially propagate new plants. For example, lemon, orange, blackberry, boysenberry, raspberry, etc. Cutting gives young children independent movements of each finger. Cutting with scissors works on the separation of two sides of the hand and strengthens hand muscles. Bilateral coordination is also addressed when they have to hold the scissors in one hand and the paper in the other. The four main types of stem cuttings are herbaceous, softwood, semi-hardwood, and hardwood. These terms reflect the growth stage of the stock plant, which is one of the most important factors influencing whether or not cuttings will root. You will get greater uniformity (clones) of your plants. The plant will reach maturity at an earlier age. When a recipe specifies how to cut an ingredient, it is important to follow the instructions because using the proper cutting technique will affect the dishes cooking time and will help ensure the food cooks more evenly and maximizes flavour.
Cutting is the easy technology to produce large number of vegetative seedlings at a time because the plants which are not susceptible can be easily propagated through this.
What is Vegetative propagation?
Many plants, especially those of horticultural and garden varieties, are propagated through cuttings. By the use of new techniques, many of the other plants formerly those which are not susceptible to the propagation of plants through cuttings which have more successfully reproduced. The plants that develop from cuttings are clones.
Most of the plant cuttings include stem pieces, and these have no root system of their own, and are therefore likely to die from dehydration of plant parts if the proper conditions are not met. Plant cuttings require a moist medium, which, however, cannot be too wet as this can rot the plant cutting. A number of media which are used in this process include however are not limited to soil, perlite, expanded clay pellets, and even water if given the right conditions. Most of the succulent cuttings can be left in open air until the cut surface dries, which may improve the formation of root when the cutting is later planted.

We have to consider that a monomer is, just like the question's statement tells us, the building block of a greater molecule. These basal units in the nucleic acids (DNA and RNA) are known as nucleotides, while are called amino acids in proteins.
3. How might the changes that you identified affect the protein’s structure?Example: The change would likely have no effect. Neither valine and isoleucine would promote hydrogen bonding with water, because their R groups are nonpolar and thus hydrophobic.Changes spotted in the previous question:1. Valine changed for Isoleucine: there was not a change in the chemical properties, because both amino acids have non-polar chains2. Valine changed for Alanine: there was not a change in the chemical properties, because both amino acids have non-polar chains3. Glutamate changed for Alanine: there was a change because the aminoacidic chain lost their electronegativity4. Glutamate changed for Aspartate: there was not a change because the aminoacidic chain kept it's electronegativity.1) _______________________________________________________________2) _______________________________________________________________3) _______________________________________________________________4) _______________________________________________________________
In the previous exercise we spotted that in the sequences there were at least four changes in the aminoacidic sequences:
1. Valine changed for Isoleucine: as indicated by the very exercise, there wouldn't be a negative effect, because both amino acids have hydrophobic radical groups.
2. Valine changed for Alanine: like in the previous case, there wouldn't be a negative effect, because both amino acids have hydrophobic radical groups.
3. Glutamate changed for Alanine: there would be a change in the protein structure because Glutamate can form hydrogen bonds, and Alanine doesn't.
4. Glutamate changed for Aspartate: there wouldn't be a change in the protein structure because both amino acids can form hydrogen bonds.
Why does the body need iron ? a. Stimulates formation of of lymph b. Forms part of hemoglobin c. Prevents destruction of red blood cells d. prevent the plaque formation in arteries
The body need iron because it is a major component of hemoglobin, an important cell for the organisms that carries oxygen from the lungs to all the parts of the body, without iron the number of hemoglobin is not enough to transport oxygen and the organism can be lead to fatigue. Therefore, the correct alternative is B. forms part of hemoglobin.
Photosynthesis, What goes in, What goes out, and Where within the cell does it occur?
Photosynthesis is the course where plants utilize sunlight, H20, and CO2 to build O2 and energy in the form of sugar.
In the course of photosynthesis, plants take in CO2 and H20 from the air and soil. Inside the plant cell, the H20 is degenerated or give up electrons, at the same time the CO2 is decreased or avails electrons. This converts the H20 into O2 and the C02 into glucose. The plant then discharges the O2 back into the air, and stock energy within the glucose molecules.
Photosynthesis takes place in small organelles called chloroplasts that stock the energy of sunlight. The chloroplasts contain the chlorophyll which is the primary pigment utilized in photosynthesis. The chloroplasts are enclosed by a double membrane and consist of a third inner membrane called thylakoid membrane that builds long folds within the organelle.
Answer - What goes in - CO2 and H20
What goes out - O2 and sugar
Where it occur - sunlight
The light reactions of photosynthesis takes place in the thylakoid membranes of the chloroplast. The light reactions catch energy from the sunlight which they alter to chemical energy and stock in molecules of NADPH and ATP.

In the figure, Side A is pure water and Side B is a 10% starch solution.
There is a semi-permeable membrane between the sides. Is this osmosis or simple diffusion? Why does the level in side B rise?
Water may pass readily across a semipermeable membrane, but solute cannot. Water travels to the solution side as the membrane divides pure water on the right from solution on the left. Osmosis is the cause of this water flow.
Why did water cross the permeable membrane from one side to the other?Osmosis is the net movement of water across a membrane that is permeable only to certain substances, and it is caused by the concentrations of different solutes on each side of the membrane.
Osmosis is the mechanism through which water diffuses across cell membranes. Osmosis is the process by which water moves from one region of low solute (dissolved material) concentration to another region of high solute concentration through a semipermeable membrane.
Osmosis is the process through which water diffuses across a semipermeable membrane based on the gradient of water concentration across the membrane. Osmosis simply moves water over a membrane, whereas diffusion moves materials both inside cells and across membranes.

Why are fossils important to developing a theory of evolution?
Photosynthesis question: Suppose that a plant had chloroplasts that could carry out the Calvin cycle, but these chloroplasts could not carry out the light-dependent reactions. Explain why these chloroplasts could not carry out photosynthesis to produce sugars.
Light-dependent reactions produce ATP and NADPH that are used during light-independent reactions. Chloroplasts could not carry out photosynthesis to produce sugars because no ATP or NADPH would be available to carry out the Calvin cycle.
What is photosynthesis?Photosynthesis is the process through which plants take solar energy to produce organic compounds. Two alternating and closely related stages are involved in this process.
Light-dependent reactionsDuring this stage, chlorophyll molecules absorb luminous energy from the sun and turn it into chemical energy.
This event takes place in the thylakoidal membrane where the electron transporter chain is located.
The final result is the production of ATP and NADPH and oxygen release from water molecules.
Light-independent reactionsThis stage is known as the Calvin cycle and occurs in the chloroplast stroma.
CO₂ enters the leaves and fixates, producing organic compounds like carbohydrates.
The whole cycle is possible because it uses ATP and NADPH produced during light-dependent reactions.
According to this information, chloroplasts could not carry out photosynthesis to produce sugars because, in the absence of light-dependent reactions, solar energy could not be absorbed, and chemical energy needed for the Calvin cycle would not be produced.

True or False: Blood sugar would be lower than normal if alpha cells constantly secreted insulin.
Answer:
The human body wants blood glucose (blood sugar) maintained in a very narrow range. Insulin and glucagon are the hormones which make this happen. Both insulin and glucagon are secreted from the pancreas, and thus are referred to as pancreatic endocrine hormones. The picture on the left shows the intimate relationship both insulin and glucagon have to each other. Note that the pancreas serves as the central player in this scheme. It is the production of insulin and glucagon by the pancreas which ultimately determines if a patient has diabetes, hypoglycemia, or some other sugar problem.

Although animal nervous systems differ in complexity, their nerve cells are still remarkably similar
a. True
b. False
It is true that, Despite the fact that the complexity of animal nervous systems varies, their nerve cells are still remarkably similar.
Nearly all multicellular animals have nerve systems, but their complexity varies greatly. Sponge and the tiny blob-like placozoan and mesozoan organisms are the only multicellular animals without a nervous system. A diffuse nerve net makes up the nervous systems of ctenophores (comb jellies) and cnidarians (such as anemones, hydras, corals, and jellyfish). With the exception of echinoderms and a few worm species, all other animals have a nervous system that includes a brain, a central cord (or two parallel cords), and nerves that radiate from the brain and central cord.
The nervous system's most fundamental roles are to direct an organism's movement and to influence its surroundings (such as through pheromones). Signals are sent from one cell to another or from one part of the body to another to accomplish this. Signals that travel to muscle cells trigger the activation of muscles and signals that travel to endocrine cells triggers the release of hormones into the bloodstream or other internal fluids are the sources of the output that the nervous system produces.

What is the meaning of life?
Answer:
The meaning of life is to positively influence as many of the lives around you as possible.
Explanation:
Some people begin to feel a sense of dread when thinking about how little space they take up, and how long they will be alive, because it seems quite small and meaningless in the grand scheme of things.
That, however, is a result of the human brain rationalizing the value and worth of something by how long it exists and how much space it takes up. In reality, something does not need to take up much space, or exist for very long, in order to be worthy and meaningful.
For instance, a hamster is very small and may live only three years before passing of old age. However, if that hamster made a person happy — filled them with joy every day when they arrived home, gave them a reason to get out of bed even when they didn't feel like it, gave them the feeling of love even while being isolated — then it had a very, very meaningful existence.
Humans are very small, and we exist for very short amounts of time, but we have the power to feel and love and change our surroundings, and as long as we leave behind a legacy of even one smile, or even one life saved (no matter how small - a lizard, perhaps), or even one moment of hope, then we will have fulfilled our purpose, and that is all we could ever ask for.

Question: Use the image to explain how ATP provides energy to your body
The image shows the process of photosynthesis where conversion of light energy to chemical energy took place by cellular respiration thereby releasing sugar in the form of glucose to provide food to plants and other organisms. ATP is produced by glycolysis and electron transport chain which serves as the energy currency of a cell which are synthesized by the mitochondria.
The image shows a representation of the carbon cycle that could also be related to our human body as well. From the image, it shows that sugar are formed by plants using carbon dioxide and the energy from the sun which can develop for their own nutrients. The process of photosynthesis where conversion of light energy to chemical energy took place by cellular respiration thereby releasing sugar in the form of glucose to provide food to plants and other organisms. When animals, even human beings consumes sugar and they can break them in ATP, which is a molecule that contains energy, can be used in multiple processes. ATP is produced by glycolysis and electron transport chain which serves as the energy currency of a cell which are synthesized by the mitochondria. The chlorophyll entagle the energy from the sun and modify it into chemical energy in the form of ATP.
The 3 Basic Components of the Cell Theory were then complete:
The 3 postulates of the Cell Theory are:
-Every living being is composed of cells, therefore they are the minimal functional unit of life, in their different levels of structural complexity. One single
cell is enough to make up an organism, but also multiple cells can organize in colonies or in a single organism, diversifying their functions and having a margin of independence quite elevated as a whole.
-All of the vital functions of living organisms have a place inside the cell, through biochemical processes and are controlled by substances that the cell secrete. Each cell operates as a unique open system, that exchanges matter, and energy with its environment in a controlled way. Moreover, in each cell of an organism are present the same vital functions that are in the organism itself, that is birth, growth, reproduction, and death.
-Every existing cell comes from a previous cell, by cell division, or by formation from stem cells.
