Which statement BEST describes what happens during the S-phase of the cell cycle?

A.Protein synthesis needed for spindle formation and mitosis.

B.DNA replication where the amount of genetic material is doubled.

C.The cell partitions the two copies of genetic material into the two daughter cells.

D.Cell division occurs and two cells are left; thus the cell cycle begins again.

Answers

Answer 1

Answer:

B

Explanation:

The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

how are utah and mexican praire dogs genes alike

Answers

Answer:

In terms of genetic variation, allelic richness (A) estimated through rarefaction resulted in 1.6–3.0 mean alleles per colony, and no private alleles were found. Mean genetic diversity (HE) was 0.525 (SD = 0.11), with values ranging from 0.276 (SD = 0.25) to 0.618 (SD = 0.09).

Explanation:

Utah prairie dog (Cynomys parvidens), and Mexican prairie dog (Cynomys mexicanus)—all of which may be considered rare (Hoogland 2006a). After 200 years of shootings, poisonings, conversion of habitat, and more recently plague, prairie dog numbers are a fraction of what they once were. Two of the species (Utah and Mexican) are listed as threatened or endangered under the Endangered Species Act (ESA).

In an area of East Texas, the most intense competition would most likely occur between white-tailed deer and

A. brown bears
B. squirrels
C. other white-tailed deer
D. coyotes

Answers

Given what we know, we can confirm that the most intense competition would most likely occur between white-tailed deer and other white-tailed deer.

Why would white-tailed deer most likely compete with themselves?

This has to do with food sources. Of the many animals listed, none of them share a food source with the white-tailed deer. The deer are herbivores that feed primarily on grass and shrubs. The bears and coyotes are carnivores that feed on other animals such as the deer themselves. While squirrels are herbivores but do not compete with the deer for food.

Therefore, given that other deer are the only animals listed that are after the same food source, we can confirm that the most intense competition would most likely occur between white-tailed deer and other white-tailed deer.

During cell polarization, the two resultant edges are called the leading edge and the trailing edge.

What do you mean by Cell polarization?

Cell polarization may be defined as a phenomenon by which cytoskeletal arrangement, extra- and intracellular signals, and organelle and membrane reorganization occur due to maintaining the cell shape.

Leading-edge works on the front edge and separates the half-wave cycle, while the trailing edge works on the back edge and cuts the second half of the wave.

Therefore, during cell polarization, the two resultant edges are called the leading edge and the trailing edge.
