science questions , may be out of order but please help asap ( about mitosis ) may be out of order so i made two questions

Answers

Answer:

8. Prophase

9. Gap 1

10.Metaphase

Explanation:

Basically from what I remember

Prophase: Mitosis begins, nuclear envelope is gone

Metaphase: Chromosomes line up and spindle fibers attatch

Anaphase: Chromosomes are torn apart to separate sides of the cell

Telophase: Separates duplicated genetic material into 2 identical nuclei

Cytokenesis: The cytoplasm itself separates and forms 2 cells.

Gap 1: Cells increase in size as new organelles are formed

Synthesis: DNA is formed

Gap 2: DNA is checked as cell begins to divide

Mitosis: Cell divides

So from the simplified versions of things I remember, I think the answers listed above probably suit each question best.

Frequent earthquakes in an area may indicate

Answers

Earthquakes occur along fault lines, cracks in Earth's crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they break loose

Frequent earthquakes in an area indicates that there are tectonic plates boundaries and there is sudden regression of underground rocks. Through the areas when there is sudden movement and dynamic stress along with the sudden triggering.

What are tectonic plates ?

Tectonic plates are larger pieces of earth's crust  and uppermost mantle. Tectonic plates movement cause the earthquakes to occur.

The other types of earthquakes are that of volcanic earthquakes, induced earthquakes and collapse earthquakes.

Therefore, earthquakes are mainly due to various conditions and other environmental activities that are not under control.

For each offspring genotype in the Punnett square you just completed, determine the phenotype. In other words, what is the predicted fur color and eye color of the offspring? Using your Punnett square from the last step, fill in the predicted fraction for each phenotype in the data table below.

Black Fur and Black Eyes Black Fur and Red Eyes White Fur and Black Eyes White Fur and Red Eyes
Predicted Fraction
/16
/16
/16
/16

Answers

Assuming diallelic genes, expressing complete dominance and not interacting, the predicted fractions are 4/16 Black Fur, Black Eyes - 4/16 Black Fur, Red Eyes - 4/16 White Fur, Black Eyes - 4/16 White Fur, Red Eyes

Available data:

Two traits are involved in this cross  ⇒  fur color and eye color.

Black fur color is dominant over white fur color

Black eyes is dominant over red eyes

The cross is between a h0m0zyg0us recessive parent with a dihybrid one.

What can we deduct about this information?

Assuming diallelic genes coding for each trait, expressing complete dominance, and no interaction between genes, we can propose the following genotypes and phenotypes.

         Genotype                               Phenotype          

BBEE, BbEE, BBEe, BbEe        Black fur, Black eyes

bbEE, bbEe                              White fur, Black eyes

BBee, Bbee                              Black fur, Red eyes

bbee                                         White fur, Red eyes

How to perform the cross?

Cross: h0m0zyg0us recessive parent with a dihybrid parent

Parental phenotypes)    White fur, Red eyes   x   Black fur, Black eyes

Parentals genotype)    bbee     x     BbEe

Gametes)  be, be, be, be

F1)

4/16 = 1/4 = 25% of the progeny is expected to be dihybrid, BbEe, expressing black fur and black eyes

4/16 = 1/4 = 25% of the progeny is expected to be heter0zyg0us for fur color and h0m0zyg0us recessive for eye color, expressing black fur and red eyes.

 

4/16 = 1/4 = 25% of the progeny is expected to be heter0zyg0us for eye color and h0m0zyg0us recessive for fur color, expressing white fur and black eyes.

4/16 = 1/4 = 25% of the progeny is expected to be h0m0zyg0us recessive, bbee, expressing white fur and red eyes.

What type of energy is used? Photosynthesis transforms ___________ energy into ___________ energy in ___________ molecules.

Answers

Answer:

Photosynthesis converts solar energy into chemical energy that plants use to make glucose so they can grow.

Explanation:

During photosynthesis, solar energy is converted into chemical energy in the form of ATP molecules.

----------------------------------------------------------------------------------------------

During photosynthesis solar energy is converted into chemical energy in the form of energy rich bond of ATP molecule.

ATP (Adenosine triphosphate) and ADP (Adenosine diphosphate) molecules are termed currency of energy. ADP molecule is converted into ATP molecules, whenever energy is available in certain exothermic reactions of metabolism.

ATP molecules are store- house of energy. ATP molecule is broken down into ADP molecule in presence of enzyme ATPase, releasing energy whenever energy is required.

The synthesis of ATP molecules, utilizing solar energy during photosynthesis, is termed photo-phosphorylation.

These ATP molecules produced during light reaction of photosynthesis are utilized in dark reaction of photosynthesis (Calvin cycle).

ATP molecules synthesized during photo-phosphorylation may also be used in other metabolic reactions.

Photo-phosphorylation is of 2 types, i.e. Cyclic and Non-cyclic photo-phosphorylation.

Chlorophyll molecules entrap solar energy . There are 2 types of photo systems in chlorophyll. These are photo-system -I and photo-system-II .

The electrons of chlorophyll molecule of photo-system I get excited which pass through series of electron carriers in electron transport system arranged in the order of decreasing energy level.

During the passage of electrons from carriers of higher energy level to the carriers of lower energy level, the energy is lost which is utilized for converting ADP molecule into ATP molecule.

Photo-system I is concerned with light reaction of photosynthesis only, constituting cyclic photo-phosphorylation.

The electron transport during Photo-system II results in the synthesis of NADPH2 in presence of enzyme NADP reductase. NADPH2 is used in reduction reaction of Calvin cycle.

Both Photo-systems participate in non-cyclic photo-phosphorylation that results in the synthesis of NADPH2 in addition to the synthesis of ATP molecules.

escribe ONE way that the use of rodenticides affects the kit fox population AND explain how the size of the kit fox population is affected.

Answers

One way that the use of rodenticides affects the kit fox population will be a

reduction in the population.

Foxes are secondary or tertiary consumers which feeds on smaller animals

such as rodents in the ecosystem. The use of rodenticides will kill and

reduce the number of rodents available for food.

The reduction in the rodents means lesser source of food for the foxes and a

decrease in the population. The size of the kit fox population is affected

because a larger size being more affected than the ones with a smaller

size/population.

Monocots differ from dicots in four distinct structural features: leaves, stems, roots and flowers. But, the differences start from the very beginning of the plant's life cycle: the seed. Within the seed lies the plant's embryo. Whereas monocots have one cotyledon (vein), dicots have two.

Similarities :-

Both monocots and dicots have stamens with two pairs of pollen sacs, male gametophytes of three cells, and female gametophytes made up of seven cells with eight nuclei. Also, the carpel is closed.

The Diagram shows structures that form the surface of the trachea.
Which level of organisation is the structure labelled S ?
A. Cell
B. Organ
C. Organ system
D. Tissue

Answers

Its the tissue that is labeled s

Structure S is a simple columnar epithelium, which is a type of tissue.

The diagram shows the structures that form the surface of the trachea. The trachea is a tube that carries air from the lungs. The surface of the trachea is lined with a layer of tissue called the epithelium. The epithelium is made up of cells that line the inside of the trachea.

The structure labelled S is a type of epithelium called a simple columnar epithelium. Simple columnar epithelia are made up of cells that are arranged in a single layer. The cells in a simple columnar epithelium are tall and column-shaped.

The simple columnar epithelium in the trachea helps to protect the trachea from infection. The cells in the epithelium produce a mucus that traps dust and other particles. The mucus is then carried away by the cilia, which are tiny hairs that line the trachea.

The other levels of organization in the diagram are organ, organ system, and cell. The trachea is an organ, which is a collection of tissues that work together to perform a specific function. The respiratory system is an organ system, which is a group of organs that work together to perform a common function. Cells are the basic units of life, and they are the building blocks of tissues, organs, and organ systems.

The breathing rate of an aquatic animal is more than that of of a terrestrial animal . Why ?​

Answers

It has to filter out the small amount of oxygen in the water, unlike terrestrial creatures.

Answer:

Since the amount of oxygen dissolved in water is comparatively lower than that in air, the aquatic animals have to breath rapidly to take in sufficient oxygen. Thus, the rate of breathing in aquatic organisms is much faster than that seen in terrestrial organisms

when a tautomeric shift occurs, what is true about the resulting mutation?

Answers

When a tautomeric shift occurs, then the resulting mutation ALWAYS changes a purine to a purine or a pyrimidine to a pyrimidine. A tautomeric shift may lead to a point mutation.

A mutation is any alteration in the nucleotide (DNA) sequence of the genome of an individual.

A tautomeric shift can be defined as a temporary change in the nucleotide base structure.

A transition mutation is a point mutation of one purine or pyrimidine base pair to the other purine/pyrimidine that occurs when one nucleotide base undergoes a tautomeric shift during DNA replication.
