Answer:

The correct answer is option B. the arctic fox changes the color of its coat when snowfalls.

Explanation:

Seasonal changes are a change that takes place every year or a certain time of the year. It normally occurs due to the unfavorable weather or environmental conditions.

During snowfall, Arctic fox changes their fur color and in summers it changes back to the dark coat that helps in camouflage so they can help to hide from predators and prey.

Thus, the correct answer is option B. the arctic fox changes the color of its coat when snowfalls.

Fungi, many birds, and a wide variety of insects all share the HABITAT of a tree in the forest.

Part of the NICHE of the fungi is to obtain energy from dead organic matter, such as dead wood.

Temperatures above 0°C and sufficient water in the environment help define the range of TOLERANCE for fungi.

Mason drew the cladogram shown. Which statements best describes the cladogram? Select three options. (HURRY I WILL MARK BRAINLIE
Yuki888 [10]

Answer: Correct options B, D and E.

Explanation:

In the cladogram, we can see that in the first branch we have a division, one branch goes to fish and the other goes to a division (a division means a common ancestor)

Then the fish are the most primitive (being directly related to the first ancestor)., E is true.

We also can see that between fish and birds we have 3 separations (the ancestor in common is 3 "generations" behind), and between frog and birds we have two separations (the common ancestor is 2 "generations" behind), so frogs are more closely related to birds than fish.

So D is also true.

We also can see that the only pair that has only one ancestor in common are birds and reptiles, so the ones that are most closely related are birds and reptiles. B is also true,

A student compares the four distinct cells that could form from the stem cell after differentiation. Which statement accurately
e-lub [12.9K]

Answer:

The statement that accurately compares and contrasts the red blood cell and the white blood cell is that both have the same copy of DNA, but different genes are expressed in the two cell types.

Explanation:

Red blood cells (RBC) and white blood cells (WBC) are two highly differentiated types of cells that come from the hematopoietic system and have different functions in the blood.

Compared to WBC , RBC cells lack a nucleus and have fewer organelles, and their function is to transport gases in the blood, unlike the former which are involved in the body's defence.

<em>Cell differentiation is based on gene expression of the genome, resulting in different types of proteins synthesized in each cell, which give them a different structure and function. </em>

Both <u>WBC and RBC have the same genome</u>, but different genes are expressed in each, giving them different morphological and functional characteristics.

Stells [14]

Answer:

A. The number of cells that are dying is balanced by the number of new cells that are being formed.

C. Harmful waste products may be accumulating.

D. The cells are likely running out of nutrients.

Explanation:

During the stationary phase, the number of viable cells remains constant. This may be due to a balance between cell division and cell death wherein the total number of newly formed cells and the cells undergoing death are equal.

Nutrient limitation is one of the several factors that make the microbial cells to enter the stationary phase. Depletion of nutrients slows down the population growth.

Accumulation of toxic waste products as it occurs during the growth of anaerobic bacteria also adversely affects the population growth.

For example, the accumulation of lactic acid and other organic acids (by-products of anaerobic respiration) inhibits the growth of the population by making the medium acidic.
