Over many generations man has chosen certain desirable characteristics in dogs by allowing dogs possessing those characteristics to reproduce. In this way, 150 breeds of dogs, same species, have descended from wolves. This process is referred to asA. convergent evolution
B. artificial selection
C. inheritance of acquired traits
D. natural selection

Answers

Answer 1

Answer:

Artificial Selection

Explanation:

Artificial selection is also called as Selective breeding where humans identify desirable traits or characteristics in animals and plants, and the action taken to promote those characteristics or traits in future generation.

Example of Selective breeding or Artificial Selection is Dog Breeding.

Artifical selection carried out in Animals and Plants have many side effects such as diseases, health disorders and obesity. It may also cause the reduction in size of the brain.

What is the final stage of cell division where the cytoplasm is divided among the two new daughter cells

Answers

Telophase -- Cytokinesis involved

(Cytokinesis is the process where the cells seperate)

Stage of cell division -- Telophase

Mitotic cell divisions

P - prophase
M - Metaphase
A - Anaphase
T - Telophase

PMAT

Final answer:

Cytokinesis is the final stage of cell division where the cytoplasm is divided to form two separate daughter cells. This follows after the completion of interphase and the four stages of mitosis. This stage ensures all genetic material, organelles, and cytoplasm are evenly divided.

Explanation:

The final stage of cell division where the cytoplasm is divided among the two new daughter cells is called cytokinesis. In the process of cell division, a cell first undergoes interphase, prepares for cell division and moves through four stages of mitosis (prophase, metaphase, anaphase, and telophase). Following this, the cell proceeds to the final stage of mitosis - telophase, where two new daughter nuclei are formed at either end of the cell.

These new nuclei surround the genetic material, which then uncoils, allowing the chromosomes to return to loosely packed chromatin. Once nuclei are formed, the cell begins to split in half, a process known as cytokinesis. This is where the cytoplasm, the internal material between the cell membrane and nucleus, is divided to form two separate daughter cells. This process also ensures that all other organelles and cellular solutes are evenly distributed between the two daughter cells.
