You are a wild rabbit and your species currently lives in desert. Most of the rabbits are brown but there are a few that are white. An asteroid hits the Earth and the environment you live in suddenly becomes very cold. It begins to snow leaving snow covering the ground. Will your species be able to adapt and line in the new environment? Explain and give details (what happens to white rabbits and brown rabbits.)
I need the brainylest answer and I will give a brainylest answer for this.
Answer:
The species of wild rabbits that are brown would most likely have a harder time adapting than the white rabbits to the new environment.
Explanation: The brown rabbits are going to have a hard time living in the snow mostly because of their color. The brown rabbit is more likely to be able to live in the desert because they can camouflauge with their surroundings (the sand). Therefore, camouflaging in the white snow to escape a predator would be impossible for brown rabbits, since they could easily be spotted. Furthermore, the white rabbits would have a higher chance of survival since they can camouflage easier in the snow.

The scientists notice that one measurement stands out.
How should the scientists best deal with this
measurement?
O accept it as true and use 85 micrometers in the data
when they find the average length
O accept it as true but say that it is the only cell that has
ever been that long
O consider that there was an error during measuring
and collect further data
O consider that it is possible but very unlikely for these
bacterial cells to be so long
Answer:
consider that there was an error during measuring
and collect further data
Explanation:
Human errors during observation are common, and although they should keep their minds open to the probability of it being longer, it is much more likely the researcher made a mistake, which they need to account for first.
What will be the effect of the damaged DNA? The role of p53 in regulating cell cycle prpgression in response to DNA damage
Answer:
Damaged DNA causes an increase in the number of mutations in the cell: this is extremely dangerous for the body and in fact this process is at the basis of the birth of cancer cells.
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

The tree population and the ground population of ticks cannot mate and have offspring indicates speciation has occurred.
What is population?"A population is defined as a group of individuals of the same species living and interbreeding within a given area."What is speciation?"Speciation is the evolutionary process by which populations evolve to become distinct species."The ticks of tree and ground population evolve without interfering with one other. Forms a different species and no mating occurs between them.Hence, the correct answer is: The tree population and the ground population of ticks cannot mate and have offspring.

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?
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.
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.

Answer:
DNA structure
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

Explanation:
After a devastating forest fire, the surrounding area contained no life. After some time, small plants began to grow along the remaining soil.
Answer:
Yes.
Explanation:
Yes, small plants began to grow along the remaining soil because of the presence of seeds in the soil that sense suitable environmental condition and come out of the soil. The ashes of burn trees have huge amount of nutrients in the form of minerals that triggers the growth of small plants. After the destruction of forest, new plants grow on that land, this type of phenomenon is called ecological succession.
Answer: CORRECT (SELECTED)
Secondary succession
Explanation:
Secondary succession occurs when a previously occupied area is recolonized after a disturbance kills most, or all, of its community.

If a mosquito cell has 3 chromosomes, is it haploid or diploid?
Answer:
If an orangutan cell had 24 chromosomes, then the cell is diploid or haploid (circle one). If a mosquito cell had 3 chromosomes, then it would be a gamete or a somatic cell (circle one).
mark me as brainlist please
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.

intermediate forms, this is an example of which category of natural selection?
Answer:
Disruptive or Diversifying selection
Explanation:
occurs when natural selection favors both extremes of continuous variation. Over time, the two extreme variations will become more common and the intermediate states will be less common or lost.
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°)
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°
