Answer:
1. Global warming (as we pass a threshold, it may be irreversible)
2. Reduce the emission of greenhouse gases
Explanation:
Climate change is a general phenomenon associated with the effects of global warming caused by anthropological activities, especially the emission of greenhouse gases (e.g., carbon dioxide, methane, nitrous oxide, etc). It has been shown that global warming is causing an increase in the temperature on the planet at a speed unprecedented since the beginning of the Industrial Revolution. The increase in greenhouse gases in the atmosphere is a direct consequence of human activities, especially from the use of fossil fuels in electricity, heating, transportation, etc. In consequence, it is possible to reduce the impact of global warming by using renewables climate-friendly energy resources, for example, by using solar panels for electricity, solar water for heating and eolic energy for industry (electricity). In this context, it should be taken into account that global warming may be irreversible, and we have the tools to stop it before it is too late.

Donna has observed that her father can control the speed of their grandfather clock by adjusting the
height of the weight on the end of the pendulum. Donna thinks that the pendulum will move faster when
the weight is lowered, and wants to test her idea. Donna gets a stopwatch and measures the time it takes
for the pendulum to swing twenty times when the weight is moved to its lowest position. Donna begins to
move the pendulum up by 1 cm and continues to measure the time for twenty swings of the pendulum.
Donna records her data.
The missing part of the question is as follows:
Position Time (seconds)
1 23.23
2 21.56
3 20.33
4 19.00
5 18.02
Hypothesis: ____________
Dependent Variable: ____________
Independent Variable: ________________
Constants: __________
Control Group:_________________
Experimental Group: ____________
Answer:
Hypothesis:
if the weight is lowered the pendulum will move faster
Dependent Variable:
Time it takes the pendulum to swing or move
Independent Variable:
the position of the weight
Constants:
same weight and the same number of swings
Control Group:
pendulum at the lowest position
Experimental Group:
different height of pendulums
Explanation:
A hypothesis is a possible explanation for the observation in a given experiment which is "if the weight is lowered the pendulum will move faster" as it states the effect of length of the pendulum on the time it takes to swing.
The dependent variable in an experiment is affected and measured to see the effect which is the time it takes the pendulum to swing or move which is measured here and affected by the independent variable that is the position of the weight.
Constants are the variable that remains constant throughout the experiment that is the same weight and the same number of swings. Control group is the group of subject or condition which minimize the effect of factors or variables except one factor to compare or ensure if the experiment works that are pendulum at the lowest position. The experiment group is the group of a subject that get treatment desired to influence the dependent variable that is the different height of pendulums.

The speed at which waves approach the shore depends on the shoreline features and the depth of the sea floor. When a wave reaches the shore, it releases a burst of energy that generates a current which runs parallel to the shoreline. What is this current called?
Answer:
Longshore current.
Explanation:
A wave is a disturbance which travels through a material medium without any permanent displacement of the particles of the medium. During the propagation of a wave, energy is transmitted from one point to another since waves flow with energy. The higher its speed of propagation, the higher the energy of the wave.
The energy released by the wave at shore produces a current which is referred to as a longshore current.
Answer:
It would be Longshore Current

Answer: ability to process foreign DNA; stop protein production
Explanation:
Compare and contrast a few aspects of animal and plant cells. You can focus on intra- and extracellular structures they share or don't share, but also be sure to describe processes they both utilize or don't both utilize. Some things to consider: How they obtain 'food' (what is their organic carbon source?) What structures do they share that prokaryotes lack? What do they share that all living cells also share? Do they use CO2, and/or O2 in any processes?
Answer and explanation:
Although they share some similarities because they are both eukaryotes, plant cells and animal cells are quite different from each other, which is logical since they have distinct lives.
For example, animal cells and plant cells both have a cell membrane, but only the plant cells have a cell wall - which is thick and resistant, and this makes sense because they are more exposed to mechanical and osmotic stress.
Since animals can move towards sources of water but plants cannot, there's also a way in which plants store water in the cells: vacuoles. Animal cells have vacuoles as well although they are much smaller than the single huge vacuole that plant cells have.
All living organisms need the energy to sustain different cellular processes. The organelle in charge of the chemical reactions behind the obtention of energy is the mitochondria, which is present in all cells, but the mitochondrion needs a specific substrate: glucose. Glucose is obtained in diverse ways: animals move and find food that contains glucose in it, while plants produce their own glucose with a specific process called photosynthesis, for which they need an organelle called chloroplast, which animals do not have. In order to transform the glucose into energy, the mitochondria end up generating CO2, which animals expel from their bodies by exhaling. This CO2, now in the air, is used by plant cells as a substrate in photosynthesis (which needs sunlight as well) to produce glucose and also O2, that will be inhaled by animals and used by their tissues.
All living organisms have one thing in common: they possess DNA. DNA contains all of the genetic information of an organism, and it is present in almost every cell of that organism -if it happens to be a multicellular being-. While prokaryotes have their DNA condensed into a single circular chromosome, eukaryotes like plants and animals, have their DNA form many linear chromosomes (quantity varies according to the species) and these chromosomes are inside a very specialized organelle: the nucleus, which prokaryotes do not have.

1. cuticle
2. leaf epidermis
3. leaf xylem
4. guard cell
5. leaf epidermis
6. stoma
7. root hair
8. ground tissue (xylem vessel)
Explanation:
functions of :
stomata aid in losing of water during transpiration
guard cells regulate the opening and closing of the stomata .this happens when the guard cells have a hypertonic environment they absorb water from the neighboring cells hence they expand and the stomata open .during the night the sugar levels in the guard cells have dropped hence they lose water to the neighbouring cells hence they shrink become flaccid and the stomata close.
xylem transports water to various parts of the plant
cuticle is a thin waxy and transparent layer.it is shiny to reduce excessive loss of water and it is transparent to allow light to penetrate through
root hairs are thin ,long and flexible.they are thin to reduce distance covered by diffusing water,they are long to allow their ability to tap water from underground,they are flexible to increase their ability to reach water sources .

Why do you think the starch molecule shown is a good source of energy for an organism?
A. The many bonds in the starch molecule store energy.
B. The starch molecule is made of atoms.
C. Starch is the only type of molecule that provides energy.
D. A starch molecule is made of more than one kind of atom.
Please help! I suck at Science!
Answer:
A
Explanation:
because it is known as a large molecule
The starch molecule is known as a good source of energy for an organism because the multiple bonds in the starch molecule are responsible for the storage of energy. Thus, the correct option for this question is A.
What is a Starch molecule?A starch molecule may be defined as a type of molecule that significantly consists of a chain of glucose molecules that are bound together in order to construct a bigger molecule, which is called a polysaccharide.
There are two types of polysaccharides present in the molecules of starch. They are as follows:
Amylose: It is a linear chain of glucose. Amylopectin: It is highly a branched chain of glucose.These long chains of glucose store a tremendous amount of energy during the synthesis of the starch molecules. Glucose provides instant energy while the breakdown of bonds in starch molecules takes time. So, the energy is liberated accordingly with a long-lasting effect.
Therefore, the multiple bonds in the starch molecule are responsible for the storage of energy. Thus, the correct option for this question is A.

Animals can help plants reproduce in a variety of ways. Which behavior can end up being more harmful than helpful?
A. Birds eat berries and seeds, dispersing the seeds in their droppings as they fly.
B. Iguanas and tortoises eat leaves, fruits, and flowers, relying on each as important
seasonal food sources.
C. Insects like bees and butterflies drink nectar, carrying pollen from one flower to
another.
D. Hummingbirds drink the nectar of flowers, and they will defend their territory in
order to secure their food supply.
Answer:
B
Explanation:
The behavior that can end up being more harmful than helpful when it comes to plant reproduction is iguanas and tortoises eating leaves, fruits, and flowers as important food sources.
When plant tissues or organs are removed, it affects the reproductive potential of such plants. Thus, Iguanas and tortoises feeding on plant tissues and organs is quite detrimental to plants and may offer very little to no benefits.
Birds help disperse seeds by feeding on fruits and dropping the seeds along with their feces. Insects like bees help pollinate flowers and hummingbirds help protect plants from certain predators. All these actions help plant reproduction.

Why does each human have two sets of 23 chromosomes? Where do those chromosome sets come from? How would your chromosomes compare to someone else’s chromosomes?
Answer:
This is because our chromosomes exist in matching pairs – with one chromosome of each pair being inherited from each biological parent. Every cell in the human body contains 23 pairs of such chromosomes; our diploid number is therefore 46, our 'haploid' number 23.
Explanation:
Humans have 23 pairs of chromosomes because 23 chromosomes come from the father and the other 23 come from the mother, and thus humans end up with 46 chromosomes. With 23 sets, you have two copies of each gene. This is what happens in normal situations. However, in some cases during cell division, there could be more or less that 46 chromosomes.
One set of 23 chromosomes is inherited from the biological mother (from the egg), and the other set is inherited from the biological father (from the sperm). Of the 23 pairs of chromosomes, the first 22 pairs are called "autosomes." The final pair is called the "sex chromosomes."
In a normal diploid cell, there are 24 *different* chromosomes out the total of 46: there are 22 pairs of identical autosomes and 2 non-identical sex chromosomes.

3. Callie has brown eyes, but her husband Joseph has blue eyes. All three of their children have
brown eyes. Do you know what Callie's genotype is? If yes, what is it? If no, why not?
Help please!!
Answer:
Since Callie has brown eyes, and all her children have brown eyes, we can only assume that the phenotype of brown eyes is dominand and Callie will have a dominant genotype, leaving Joseph to have a reccesive genotype (if Joseph was heterozygous for this aspect, he would have brown eyes) and the children will be heterozygous, with brown eyes as this characteristic predominates over blue eyes.

Compare and contrast characteristics and use his own diodes and triodes
Answer:
Comparison of characteristics and use of diodes and triodes is given below:
Diode and triodes both are electrical components but diode allows the flow of current in only one direction while triode has three electrodes.Diode consists of two terminal (anode and cathode) while Triodes have three terminals (cathode, anode, and grid). A diode is an electrical component used to control voltage while triode is a current controlled device. Diodes used in modern electronics such as LED while triodes are used in RF heating systems.Answer:
1. Conditions that result in the emission of electrons from a conductor:
Heating the conductor to a suitable temperature
Exposing the conductor to a strong light
Subjecting the conductor to a very high applied voltage
Subjecting the conductor to high-speed electrons from another source
2. Both diodes and triodes influence current flow and contain electrodes. Diodes involve only two active pieces; triodes contain three electrodes within a tube. Current can flow through a diode in only one direction. Diodes tend to act as rectifiers. In a triode, the third electrode is a grid located between the cathode and the anode. A small difference of potential between the grid and the cathode controls the number of electrons that reach the anode. Adjusting the charge on the grid affects the number of electrons that can reach the anode. Triodes tend to act as amplifiers.
