The root cap??? I think not for sure though.
The fourth one that looks like an M. This is because it describes changes in population genetics in which extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups.
Answer:
47 chromosomes
Explanation:
Meiosis is a kind of division that reduces the chromosome number of the daughter cells by half i.e. 2n - n. It occurs only in reproductive cells to produce sex cells or gametes. In humans, meiosis occurs to produce gametes (egg and sperm) that have 23 haploid chromosomes.
N.B: Somatic human cells have 46 chromosomes
According to this question, a meiotic error occurred during gamete formation, resulting in an egg that has 24 chromosomes. If that egg is fertilized by a normal sperm i.e. sperm with 23 chromosomes. A zygote that posseses (23 + 24) = 47 chromosomes will be produced.
Stem cells<span> are a class of undifferentiated </span>cells<span> that are able to differentiate into specialized </span>cell<span> types. Commonly, </span>stem cells<span> come from two main sources: Embryos formed during the blastocyst phase of embryological development (embryonic </span>stem cells<span>) and. Adult tissue (adult </span>stem cells<span>).
