Answer:
1 in 16
Explanation:
When two heterozygotes (AaBb x AaBb) for two autosomal genes are crossed the expected probability for the offspring is 9 A-B-, 3 A-bb, 3 aaB- and 1 aabb. In other words, out of sixteen offspring, 9 are expected to be dominant on both genes (either homozygous AA or BB or heterozygous Aa or Bb), 3 are expected to be dominant on the A gene but recessive on the b gene, 3 are expected to be recessive on the a gene but dominant on the A gene, and only 1 is expected to be recessive on both genes aabb.

Answer:
c. Glycolysis evolved in an oxygen-rich environment.
Explanation:
Glycolysis is the pathway that breaks down glucose into two molecules of pyruvate. It is a common pathway that is performed by both aerobic and anaerobic organisms. In aerobic organisms, glycolysis is followed by Kreb's cycle and electron transport chain. In anaerobic organisms, alcohol or lactic acid fermentation regenerate the NAD+ which is required to sustain glycolysis.
Therefore, glycolysis is independent of oxygen availability and can be performed under both aerobic and anaerobic conditions. This means that the pathway of glycolysis evolved under anaerobic conditions.
Answer:
a. methylation at lysine 9 or 27 of histone H3.
Explanation:
Methylation causes the switching off of genes using steric hinderance to prevent access to DNA.
When someone moves to a place of higher education, financial issues are usually a big factor. Can they afford it? Is there ways help lower costs? Are they eligible for scholarships? Would they make enough to pay any student loans they may take? People also need to worry about if they have enough for a place to stay while in school, they also need to look at transportation. All of these factors are things that involve finance
