Prophase is the first stage of cell division, during which the genetic material condenses into chromosomes, the nuclear envelope breaks down, and the mitotic apparatus forms.
During prophase, the first stage of cell division in both mitosis and meiosis, several important events occur. Initially, the genetic material within the nucleus, which usually exists in a loose, unorganized state, condenses into visible and distinct chromosomes. Each chromosome replicates into two identical sister chromatids, bound together by a structure called a centromere.
As prophase progresses, the nuclear envelope begins to break down, and the nucleolus disappears. In the cytoplasm, specialized structures known as centrioles start to move towards opposite ends of the cell, forming a structure known as the mitotic (or spindle) apparatus, which will aid in the separation of the sister chromatids in later stages.
In essence, what happensduring prophase is the preparation of the cell for subsequent stages of cell division, by organizing its genetic material and forming necessary structures.

The moon exerts a gravitational pull on the earth. The pull stretches the earth's watery envelope and creates tidal bulges. Where the water bulges out is low tide.
B.
The moon's gravity pushes on the earth. The push indents the earth's watery envelope and creates tidal bulges. Where the water is pushed in is low tide.
C.
The moon exerts pull on the earth. The pull stretches the earth's watery envelope and creates tidal bulges. Where the water is thinnest is low tide.
D.
The moon's gravity pushes on the earth. The push indents the earth's watery envelope and creates tidal bulges. Where the water is pushed out is low tide.
B.) cause a child to appear more different from his or her parents than from his or her great-grandparents.
C.) do not relate to physical appearances.
D.) cannot be passed on to future generations.
I think I know what it is I just want to make sure.
Answer:
the right answer is D.) cannot be passed on to future generations.
Explanation:
Because i answered it and got it right
Answer: Dominant: red, recessive: white.
Explanation:
Alleles are different forms or versions of a gene, and they can be described as either dominant or recessive.
Dominant traits are those that are seen in a heterozygous genotype. It means the organisms has two different alleles for a gene, one is dominant while the other one is recessive. A dominant allle dominates over the recessive alleles and it masks the effects of this recessive allele. This means, the offspring only needs to inherit one dominant allele to have a dominant trait.
In the example, a red-flowered plant is crossed with a white-flowered plant. And all plants on the next generation are red. If each plant from this offspring inherites one allele of each parent, they have one red allele and one white allele. Since they are all red, we can say red color is dominant and white color is recessive. Because red allele has a dominant phenotype.
