D. The wavelengthN of night between 400nim and 700nm are the wavelengths that are lnortet by chlorophyll and that drive cellular respiration​

Answers

The answer for this would be A because

As per diagram B of the four answers the wavelength. The wavelength are given in the visible bands and range form 400 to 700 nm. As per the absorption efficiency the band B has larger capacity than the band A.

Hence the wavelength of sunlight between the 400nm and the 7000nm ae the wavelengths that are absorbed by the and mitochondria that drive the process of cellular respiration.

The point where separation of the DNA occurs is called the replication fork.

True
False

Answers

Answer:

True

Explanation:

The point where the separation of the DNA occurs is called the replication fork. Therefore, it is true.

What is a replication fork?

The DNA double helix of a cell has been unwound and split into the replication fork, which is where DNA polymerases and other enzymes can work.

DNA helicases unwind DNA at locations known as origins during DNA replication, where synthesis will begin. The replication fork, so named because the two strands of DNA seem forked as they are unzipped apart, is a structure that is created while DNA helicase proceeds to unwind the DNA.

A replication bubble is created when the circular bacteria chromosome's double-stranded DNA is opened at the point of replication. A replication fork, a Y-shaped junction where double-stranded DNA is split into two single strands, is present at each end of the bubble. Therefore, it is true.

A) There are approximately 917 cells in interphase. Disruption of interphase will have no effect on mitosis because they are two completely independent processes.

B)There are approximately 83 cells in interphase. Disruption of interphase will lead to a faster and more efficient mitotic cycle, which will result in increased cell division and tissue growth.

C)There are approximately 917 cells in interphase. Disruption of interphase will trigger the cell to switch to a mitotic phase and repeatedly divide, which will result in the massive proliferation of the cells and heightened tissue growth.

D)There are approximately 83 cells in interphase. Disruption of interphase will result in the cell being unable to synthesize proteins and organelles required to divide, which will result in the cell not passing key checkpoints and ceasing to divide.

Please help me!! what is the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy?

Answers

Answer:

3/16

Explanation:

This question involves two genes coding for pea shape and pea color. The alleles for yellow color (Y) and round seeds (R) are dominant over the alleles for green color (y) and wrinkled seeds (r).

In this cross between two heterozygotes: RrYy × RrYy, the following allele combinations are produced in the gamete of each parent: RY, Ry, rY and ry. Using these gametes in a punnet square (see attached image), the following offsprings are produced:

9/16 of Round, yellow offsprings (R_Y_)

3/16 of Round, green offsprings (R_yy)

3/16 of Wrinkled, yellow offsprings (rrY_)

1/16 of wrinkled, yellow offsprings (rryy)

Hence, the probability that a yellow (Y) and wrinkled (r) pea will appear from a cross of RrYy x RrYy is 3/16.

b Protein molecules make up the membrane, which makes it a strong structure.
c The plasma membrane is made mainly from carbohydrates that give the cell energy.
d It is made primarily of cholesterol that allows the cells to communicate with others.

Answers

Answer:

A. It is a lipid bilayer with the hydrophobic area pointing inward, and the hydrophilic area facing outward.

Explanation:

The plasma membrane (also known as the cell membrane) is a membrane that separates the cell's interior from the environment that surrounds it, protecting it. It consists of lipids, proteins, and carbohydrates.

Its main component are phospholipids that create a bilayer. Phospholipids consist of two hydrophobic tails and a hydrophilic head and are arranged so that the tails face inward and the heads outwards.  

This is why option A is the correct one.

Explain the energy transformation that occurs when a person exercises.

Answers

Answer:

Electrical energy is defined as the energy flowing through a device due to the flow of electrons or charges from one point to another.

The energy present within an object or material due to the sum of its motion and potential energy is known as mechanical energy.

Thermal energy is defined as the energy present within an object because of the motion of its particles.

So, when we plug in and turn on a hair dryer then electrical energy starts to flow. As a result, some of its molecules will gain kinetic energy and some will have potential energy.

Hence, its sum will lead to formation of a mechanical energy. Since, this mechanical energy gets converted into thermal energy due to which hairs get dry.

Thus, we can conclude that the energy transformation that occurs when a hair dryer is plugged in and turned on is that electrical energy transforms into mechanical and thermal energy.
