The answer for that question is A
Answer:
the outer layer of the star expands
Explanation:
Gravity pulls gas and dust together. A protostar forms as mass increases. A black hole forms as the core collapses.
Explanation:
Meiosis is a type of cell division in which the ploidy of the organism reduces to half in the daughter cells.
Meiosis produces 4 daughter cells from 1 parent cell with a different combination of the genetic material but haploid chromosomes.
The meiosis process takes place in two stages in which during the first stage, the homologous chromosomes separate reducing the chromosome number to half that is from diploid chromosomes of parents to haploid in daughter.
Since the process of meiosis form haploid gametes in both male and female therefore after fertilization restores the diploid chromosomes of the parent cell and form a diploid structure.
<span>multiple alleles, three or more alternative forms of a gene (alleles) that can occupy the same locus. However, only two of the alleles can be present in a single organism.</span>
The nucleus is responsible for housing the nucleolus, storing DNA, and housing chromosomes. Digesting bacteria is the responsibility of a different organelle.
