A.
Explanation:
Lysis is best described as :
A. When a cell takes in too much water from Osmosis, swells and bursts.
Hope it helps!
Answer:
Atoms In The Mix
Explanation:
Water molecules are shown as H₂O. That is because water contains two hydrogen atoms and one oxygen atom. Carbon dioxide is a molecule that contains one carbon and two oxygen atoms.
A. Genotypes of parents are LL and ll
B. 100% Ll and all long tails
C. 50% Ll 50% ll half short tails half long tails

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.
