Answer:
The two types of cells that never go through cell division once fully formed are nerve cells and muscle cells.
Explanation:
The nerve cells and the muscle cells not undergo cell division after formation, because they can never re grow or cannot be repaired once they are mature. We should take good care of it once they are matured. They just under division from being baby to teenagers after that they stop undergoing cell division. This is true for both elephants as well as human beings. This thing is also applicable in case of bones.
Answer:
If the question is referring to Mendel's postulates, all options are correct
Explanation:
Gregor Mendel discovered that certain components he called UNIT FACTORS determine inheritance. This unit factors were later described to be genes in modern genetics. He discovered that an organism receives two forms of this unit factors from each parent, which he called ALLELES. In his experiments, he observed that one of the pair of alleles have the ability to mask the expression of its variant pair. He called the allele that masks, DOMINANT allele while the allele that is masked, RECESSIVE allele.
During his cross experiment, he discovered that the alleles of a gene (unit factor) separates into gametes, he called this LAW OF SEGREGATION. He notably discovered in his cross involving two different characters that the segregation of the alleles of one gene into gametes does not influence the segregation of the alleles of the other gene. He termed this his LAW OF INDEPENDENT ASSORTMENT.
Answer:The answer is option A sister chromatids are separated from each other to form gametes.
Explanation:
Meiosis is a type of cell division which produces 4 daughter cells with different genetic material. The ploidy number or set of chromosomes is reduced to half in the newly formed daughter cells.This process usually proceeds in two divisions-meiosis I and meiosis II with four stages in each division which are prophase, metaphase, anaphase and telophase.Sister chromatids separate from each other during anaphase II of meiosis II which produces four haploid gametes from two intermediate cells formed by meiosis I.Thus, sister chromatids are separated from each other to form gametes is the correct answer.
When you relax the smooth muscles in arteries, it affects the blood pressure quite a lot. If you're a up and running person, you're most likely not always relaxed. Although - if you manage to relax, it would cause your blood pressure to lower from a high rate, to a much lower rate. That's the main outcome of this.
