Answer:
The cell’s membrane separates the cytoplasm, forming two cells.
Explanation:
Cytokinesis is the physical process during cell division that separates the cytoplasm of the parental cell into two different daughter cells. Cytokinesis occurs after the telophase of mitosis. During this process, the cell membrane grows to surround each daughter cell and thus separate them. In animal cells, cytokinesis occurs by a ring of contractile microfilaments that lead to the constriction of the parental cell.

Answers
Answer:
There are 4 kingdoms
There are currently four kingdoms in the domain named Eukarya. The correct option is c.
What is domain?In biological classification, a domain is a taxonomic category above the kingdom level. Bacteria, Archaea, and Eukarya are the three domains of life.
These domains are defined by differences in cell structure, biochemistry, and other characteristics of the organisms that inhabit them.
Bacteria and Archaea are both prokaryotic domains, whereas Eukarya is a eukaryotic organism domain that includes animals, plants, fungi, and protists.
In biology, a kingdom is a taxonomic rank made up of smaller groups known as phyla (or divisions, in plants).
Historically, the highest taxonomic rank, or the most general taxon used in classifying organisms, is kingdom.
Animalia, Plantae, Fungi, and Protista are the current kingdoms in the domain Eukarya.
Thus, the correct option is c.

Brown eyes in humans are dominant to blue eyes. A brown-eyed man, whose mother was blue-eyed, marries a brown-eyed woman whose father had blue eyes. Figure out each member’s genotype
Answers
Answer:
Man: Bb
Man’s mother: bb
Woman:Bb
Woman’s father: bb
Explanation:
Brown eyes are dominant over blue eyes, so, in order for a person to have blue eyes, they must carry both recessive alleles for blue. This means the man’s mother and the woman’s father must have the genotype bb. The man and the woman on the other hand have brown eyes, which means they got the dominant brown eye trait from their other parent and will have a heterozygous genotype Bb.
