Answer:
The process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin, and it is now regarded as be the main process that brings about evolution.
Explanation:
For question number 1, there is one phenotype only with homozygous allele which are recessive and dominant of both parents. For question number 2, the answer is letter B. plants with both red and blue flowers because it is codominant so the trait will express both alleles. For question number 3, the answer is letter C. four genetically identical cells because it is from two daughter cells which undergo meiosis that results into 4 identical cells that are needed for somatic cells in our body. For question number 4, the answer is the leading strand is copied in the 5’ to 3’ direction and the lagging strand is copied in the 3’ to 5 because it is based in the ends of each nucleotides that is carrying the genes. For question number 5, the answer is gene regulation which is used by cells to increase of decrease specific gene products or RNA.
Lactic acid fermentation occurs as an alternative to that of aerobic respiration, this occurs in cases where oxygen levels or concentrations within the cells are very low and as a result, is not available for the acceptance of electrons as the final electron acceptor. The cells undergo this process, where essentially, rather mr than using oxygen as the final electron acceptor after producing ATP. NAD+ I believe is able to accept electrons and thus we can produce ATP, again. Glycolysis occurs but rather than moving on to the next stage, Pyruvate molecules are ultimately converted to lactic acid which releases ATP, the extra electrons would go to NAD+ which is needed to keep the reactions going.
That is roughly 0.0 24–0.0 72 ounces per day and 927 ounces slashed year or 0.55 through 1.6 pounds per year
Answer:
d. Citric acid cycle
Explanation:
The only process in the list that requires the presence of O2 in order to occur is the Citric acid cycle or Krebs cycle. This cycle is part of the aerobic cellular respiration and it occurs only when O2 is available. If there is no oxygen, an alternative process that could happen is fermentation, but this is only carried by some microorganisms and some cells such as muscle cells.
In fact, oxygen is not needed by citric acid cycle but it is by the next step: the electron transport chain. In this chain, oxygen is the final acceptor of electrons, and without oxygen, the Krebs cycle doesn't occur because the final electron transport chain can't be done.
