Answer is
A) Electrón trasport chain
I pretty sure that it include both biotic and abiotic. But "C" is wrong. Now your answers are between "A,B and C"
<span>HWE is used with COIDS and non CODIS eligible DNA profiles to provide statistical caluclations for the rarity or uniqueness of profiles. Each STR kit test for a certian number of loci. Each lous has a set ladder of observed alleles. Each of these alleles has value for its observed frequency in a population. It is the rarity of each allele at each location that will give you the value for rarity of the profile as a whole. This rarity fo the profile is calucalted in CODIS under certian circumstances using to determine the eligibilty of a partial profile or a forensic mixture to determine its eligiblity for the different leves of the database.</span>
Answer:
(a) crossing over: Meiosis I, Recombination
(b) chromatids separate at their centromeres and migrate to opposite poles: Meiosis II, Anaphase II
(c) chromosomes become aligned in pairs at the equator: Meiosis II, Metaphase II
Explanation:
Homologous recombination is a type of genetic recombination that occurs during meiosis (formation of ovum and sperm cells). The paired chromosomes of the male and female parents are aligned so that similar DNA sequences intersect. This crossing over produces an exchange of genetic material, which is an important cause of the genetic variability observed in the offspring.
Meiosis II: Anaphase II. The centromeres separate and the daughter chromatids - now individual chromosomes - move to the opposite poles of the cell. The centromeres separate, and the two chromatids of each chromosome move toward the opposite poles in the spindle.
Meiosis II: Metaphase II. Chromosomes are accommodated in the equatorial plate of metaphase, similar to what happens in mitosis. They are attached to the already fully formed meiotic spindle. Each chromosome is aligned in the equatorial plate of the metaphase, as it happens in mitosis.
The answer would be the chloroplast. The cell wall mainly covers and protects the cell's insides.
