A, I’m pretty sure, Meiosis helps with genetic diversity
Answer:
<em>If crossing over did not occur there would be no diversity among organisms.</em>
Explanation:
Crossing over and independent assortment are the two phenomena of meiosis by which genetic and physical diversity occurs. If crossing over did not occur then there would not be changes in the physical features of children. No physical diversity would be produced. Children would have the same physical features as the parents. Each chromosome would be identical to one of the parents and hence there will be reduced variations.
Hello!!
A: Anaphase — 1 chromatids move towards opposite poles. I always remember that “Ana” moves to different places on the sides of town. This is where the chromatids begin to move.
B: Telophase — 4 Cytokinesis may occur. Cytokinesis is the last and final step. The sister chromatids finish moving towards the poles and then cytokinesis occurs.
C: Metaphase — 3 Chromatids line up in the middle of the cell. I always remember since they line up in the middle, they “met” there.
D: Prophase — 2 and 5 Disintegration of the nuclear membrane and the spindle forms. Both of these have to happen first in order for the rest of the processes to occur.
**The order of mitosis goes prophase, prometaphase, Metaphase, Anaphase, Telophase, and Cytokinesis.**
For the bottom:
A: Algae 6 and 10. Both diatoms and kelps (plant related) are a part of the Algae general type.
B: Fungi 7 and 9. Deuteromycetes and Ascomycetes.
C: Protozoa 8. It is ciliates because they are a major group of Protozoa from cilia.
I hope I helped!! Have a great day!! :)
Answer:
Genetic engineering has been used to mass-produce insulin (for diabetics). It has also been used to create human growth hormones, infertility drugs, human albumin, monoclonal antibodies, antihemophilic factors, vaccines, and many other drugs.
Have a nice day! (Please give me brainliest and thank you!)
