Answer:

c. Crossing over

Explanation:

In meiosis, crossing over refers to the process where homologous chromosomes 'combine' with each other in order to exchange genetic material, which results in genetic variation. This process takes place during Prophase I of the first meiotic division.

Crossing over is extremely important for the variation - and survival - of a species, as it results in numerous genetic combinations that are passed from generation to generation.

Juli2301 [7.4K]

Final velocity after 5 sec is 16 m/s

Given that;

Initial velocity = 4.5 m/s

Constant acceleration = 2.3 m/s²

Time taken = 5 second

Find:

Final velocity

Computation:

Using first equation of motion;

v = u + at

v = 4.5 + (2.3)(5)

v = 4.5 + 11.5

v = 16 m/s

Final velocity = 16 m/s

Answer:

Prophase, metaphase, anaphase, and telophase.

Explanation:

Mitosis is a type of cell division in which a single mature parent cell is divided into two daughter cells having double number of chromosomes and identical to parent cell. There are four phases of mitosis which are prophase, metaphase, anaphase, and telophase. During prophase phase, chromatin condenses into chromosomes. During prophase phase, the chromosomes of the cell align themselves in the middle of the cell. During prophase phase, During prophase phase, the splitting of chromosomes occur and the separated chromosomes goes to the opposite poles of the cell. During telophase, it results in the production of two nonidentical daughter cells.
