Answer: Meiosis is a process in which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell. Meiosis usually involves two distinct divisions, called meiosis I and meiosis II. By the end of meiosis II, the diploid cell becomes four haploid cells.
Explanation:
1. mitochondria
2. rough endoplasmic reticulum
3. plasma membrane
4. nucleus
They are all mechanisms of <u>Evolution </u>and can change allele frequencies in populations
Natural selection, mutation, genetic drift and gene flow are all capable of causing varying changes in allele frequencies in a population. and these changes leads to the violation of Hardy-Weinberg assumptions
Hardy-Weinberg assumption states that; for a population to experience an unchanged allele frequencies, certain conditions must be met by the population such as ; absence of natural, random mating , absence of migration and absence of mutation.
Hence we can conclude that Natural selection , mutation, genetic drift and gene flow are all mechanisms of <u>Evolution </u>and can change allele frequencies in populations

Answer:
No
Explanation:
For having a daughter of AB blood group A and B alleles are very important. A person with O-blood group has only OO alleles so the answer is No.
Answer:
Plant cells have cell walls.
Explanation:
While both plant cells and animal cells have cell membranes, only plant cells have a cell wall, the hard outer shell of the cell.
