Answer:
D. Fatty Acids
Explanation:
When fatty acids undergo beta-oxidation to serve as a source of ATPs, ketone bodies are produced. During starvation or medical conditions such as diabetes mellitus, carbohydrate supply to liver cells is depleted.
Once the stored glycogen has been depleted from the liver cells, the fatty acids are funneled into beta-oxidation to produce ATPs. The process also forms acetone, acetoacetate, and D-beta-hydroxybutyrate, that is the ketone bodies. The more the fatty acid molecules enter the beta oxidation, the more ketone bodies are produced.
Answer:
25%
Explanation:
Here's an example: two chickens have the phenotype of white feathers and brown feathers. What percentage of the chicks will have the recessive color? First, you have to see the parents' phenotypes. Draw a punnet square. Put one of the parent's phenotypes (w and B) on the top, and the other parent's (w and B) on the right side going down. Whichever trait is dominant (brown) MUST be capitalized. Then, cross the two parents. first box on the top left would read 'ww.' The one below it is 'Bw' (put the dominant first). The right top is 'Bw' and the one below it is 'BB'. So if there were 4 offspring, these would be their genotypes: 'ww', 'Bw', 'Bw', and 'BB'. The only offspring that would have the recessive trait is the 'ww' child, because dominant overpowers recessive. So 25% would have the recessive trait and 75% would have the dominant trait.
Answer: knowing that the number of adenine will be always equal to the number of thymine.
Explanation:On the basis of base pairing rule, the purine bases bonds with the pyrimidine bases. This takes place as the configurations of pyrimidine and purine bases permit formation of hydrogen bonding between the two.
The base pairing rule suggests that the pairing of adenine takes place only with thymine and pairing of guanine takes place only with cytosine. Two hydrogen bonds are produced between an adenine and thymine base pair, while three hydrogen bonds are produced between a guanine and cytosine base pair.
Bottleneck is the term used to define chance changes in the frequency of alleles which have a significant effect on small populations. The effect is that the population is greatly reduced because of the change in the allele frequency. A genetic drift will follow which will expedite evolution.
