Meiosis in reproductive organs (testes and ovary) produce gametes. Each human cell including reproductive cells contains 23 pair of chromosomes. Meiosis separates the two chromosomes from each pair thus, each gamete receives only one copy of each chromosome. Therefore, each gamete has 23 new chromosomes, one from each of the 23 pairs. During meiosis, exchange of chromosome segment between copies of a pair of chromosomes. The exchange of chromosome segments creates new combinations of genes which enhances genetic variability within a species.
Answer:
The correct answer is - Protect organs
Explanation:
The skeletal system is the internal frame of the body that includes all the bones and joints present in the body. There are 206 bones in the adult human skeletal system.
The major roles of the skeletal system to help in movement, support, and protecting vital organs such as hearts, stomach, lungs, brain, and other organs. It also helps in movement and providing support to the body.
Answer:
by inhibiting the mitotic spindle plasticity
Explanation:
In eukaryotic cells, the mitotic spindle is the cytoskeletal structure by which sister chromatids are separated during cell division. Spindle microtubules are known to drive chromosome segregation, while tubulins are Microtubule-Associated Proteins (MAPs) that attach to microtubules in order to modulate their dynamics. Antimitotic drugs are nowadays widely used in chemotherapy to disrupt microtubule assembly and chromosome segregation, thereby producing mitotic arrest and cell death (apoptosis).
