Name two types of proteins that regulate the cell cycle. How do these proteins work?

Answers

Answer:

Internal and external regulators are two types of proteins that regulate the cell cycle. Internal regulators allow the cell cycle to proceed only after certain events occur. External regulators speed up or slow down the cell cycle.

Explanation:

I hope this helps :)

The two types of proteins that regulate the cell cycle are Cyclins and Cyclin-dependent Kinases (CDKs). These two groups of proteins are responsible for the progress of the cell through various checkpoints.

What are Proteins?

Proteins are made up of hundreds or thousands of smaller units called Amino acids. They are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs.

Cyclins regulate the cell cycle only when they are bound to Cdks and become fully active. The Cdk/cyclin complex must be phosphorylated, which further initiates other proteins to be phosphorylated that advances the cell cycle.

Retinoblastoma (Rb), is another group of tumor-suppressor proteins that regulates the cell cycle by monitoring the cell size.

Therefore, there are two types of proteins that regulate the process of the cell cycle are Cyclins and Cyclin-dependent Kinases (CDKs).

All mosquitoes have six diploid chromosomes (2N = 6), and their chromosomes are either submetacentric or metacentric, mosquito cell has 3 chromosomes and is haploid.

What is the difference between haploid and diploid?

Three pairs of chromosomes make up the Anopheles mosquito's chromosomal complement: two sex chromosomes As a consequence, when a sperm and egg cell join during fertilization, the resultant zygote has 46 chromosomes.

The number of chromosomes and their shape in mosquitoes are extremely similar mosquito cell has 3 chromosomes, and are haploid.

Therefore, to go from haploid to diploid cells, we only need to double the number of chromosomes. This quantity is denoted by the abbreviation 2n, where n is the number of chromosomes.

Bobcats are generally solitary and establish territories of a certain size where they hunt for food. What type of population dispersion would you expect bobcats to have?

Answers

Answer:

Uniform dispersion.

Explanation:

The bobcats' population distribution would be a uniform dispersion because they are distributed in an area in a balanced way. That is to say, that there is space between them and that each bobcat establishes its personal space when hunting and for their daily life. As they are solitary animals, they do not live in groups and only associate with other bobcats to reproduce themselves.

Why are seismic waves considered
mechanical waves?
A. They must travel through a medium, such as
the bedrock of the Earth.
B. They will only travel through empty space.
C. They travel in circles.
D. They do not require a medium.

Answers

Answer:

The correct answer is - option A.

Explanation:

The seismic waves are the waves that are the result of an explosion or the breaking of the rock within the earth. In other words, when these explosions or breaking cause an energy transfer within the earth are seismic waves. Seismic waves require a medium to travel and normally it is the earth.

The bedrock of earth is a great example of a medium for traveling these waves that make it a mechanical wave. Earthquake is the result of such waves.

A ray of light is passing through a medium making an angle of 45°. If the
refractive index of the medium is 1.4, calculate the angle of refraction. [Ans: 30°)​

Answers

Answer: By Snell's law, we can see that the angle of refraction is 30.34°

Explanation:

Snell's law says that:

If a ray in a medium of refractive index n₁, insides with an angle θ₁ in another medium with refractive index n₂, then the angle of refraction θ₂ is given by:

n₁*sin(θ₁) = n₂*sin(θ₂)

We know that:

The incidence angle is 45°, then: θ₁ = 45°

We can assume that the first medium is air, then n₁ = 1

The refractive index of the other medium is 1.4, then n₂ = 1.4

Replacing these in the Snell's law equation we get:

1*sin(45°) = 1.4*sin(θ₂)

Now we can solve this for the angle of refraction:

sin(45°)/1.4 = sin(θ₂)

Asin(sin(45°)/1.4 ) = Asin( sin(θ₂)) =  θ₂ = 30.34°

So the angle of refraction is 30.34°

Civil engineers want to determine whether the porosity of surface soil affects aquifer recharge rates

Answers


Aquifer recharge is water that moves from the land surface or unsaturated zone into the saturated zone. Quantitative estimation of recharge rate contributes to the understanding of large-scale hydrologic processes. It is important for evaluating the sustainability of groundwater supplies, though it does not equate with a sustainable rate of extraction. Where contamination of an aquifer is a concern, estimating the recharge rate is a first step toward predicting solute transport to the aquifer. Recharge may cause a short- or long-term rise of the water table. Artificial drainage, e.g., with horizontal porous pipes buried at a chosen depth, is sometimes used to maintain a minimal thickness of vadose zone for agricultural or other purposes.
Recharge rates vary considerably in time and space. Recharge often occurs episodically in response to storms and other short-term, high-intensity inputs. For a given amount of infiltration, temporal concentration enhances recharge because it entails shorter residence times for water in the portions of the soil from which evapotranspiration takes place. Similarly, a larger fraction will become recharge if it is concentrated in narrow channels such as fingers or macropores, not only because this tends to hasten its passage through the unsaturated zone, but also because the water then occupies less of the volume of soil from which evapotranspiration takes place.

To avoid this, the cell is equipped with some molecular protective systems including the activation of the p53 protein. p53 induces recruitment of DNA damage repair systems and stops cell replication until the damage has been repaired. If the damage cannot be repaired p53 induces cell death through apoptosis
