Matching questions match each description with the appropriate phase of mitosis:
strojnjashka [21]
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!! :)

You are counseling a young Greek couple because both parents and their first-born son have been tested and found to be carriers
Rina8888 [55]

Answer&Explanation:An individual with an autosomal dominant disorder, has a single mutant gene unless when their both parents are affected.

A person will have an autosomal dominant disorder if only a single parent is affected and if parent have autosomal dominant disorder only there is a 50% of inheriting a mutant gene.

In autosomal recessive disorders a person will get Ill if they inherit both mutant genes from both parents who are carriers . This person will be homozygous for the gene and will be affected by the disorder and this is highly likely to happen in their baby since they are both the carriers of this disorder.
