Answer 1

4. Spindle fibres for cellular division form during Prophase.

The spindle fibers begin to form during prophase of cell division. During prophase, the nucleus disappears, spindle fibers form, and DNA condenses into chromosomes ( sister chromatids). The cell's centrosomes small organelles that organize and arrange the microtubules begin to form microtubules.

5. A cell with 2n=4 chromosomes enter mitosis. What will be the outcome per nucleus at telophase is 2n=2.

Mitosis ends with 2 identical cells, each with 2N chromosomes and 2X DNA content. ie., a diploid body cell contains 2n = 2 chromosomes. For example one chromosome came from mom and one from dad. In humans, 2n = 46, so 23 came from mom, and 23 from dad.

6. Which process(es) do eukaryotic organisms use for growth and repair of damaged tissue - Mitosis.

The process of mitosis is essential for growth and repair processes of eukaryotic organisms. For example mitosis is how we are able to replace our fingernails and hair as well as how our skin is replaced.

7. Comparing human females to males

22 pairs of chromosomes will look the same between female and male karyotype

The two sex chromosomes of human females look the same

The two sex chromosomes of human males are heterogeneous
