Answer:
1. Using the graph, describe the events that occur in the body during the first year of
HIV infection.
2. Describe what happens between the first year and the tenth year of infection.
3. Explain why the concentration of antibodies begins to decrease after nine years of
infection.
4. At what point on the graph does an infected person have AIDS?
5. Why does the number of HIV particles begin to level off after nine years?
6. How do you think the high rates of HIV transmission in humans might be related to the length of time it takes for the virus to develop into AIDS?
Out of the following given choices;
<span>A) </span>increase; increase B) decrease; increase C) increase; decrease D) decrease; decrease
The answer is A. Increased hunger causes an increased appetite that is due to increased episodes of hypoglycemia (low blood sugars). This is due to an increase in metabolic rate that breaks up glucose for energy at very high rates.
The genotypes of the parents are Aa (heterozygous) and aa (recessive homozygous).
For example:
If the purple flower is dominant phenotype, then A is a dominant allele for it and Aa is a genotype which will give the purple colour.
In this case, white flower is recessive phenotype with aa genotype.
If we cross Aa x aa
<span>The offspring is going to be Aa Aa aa aa (half purple and half white)</span>
Semi-conservative DNA replication means that one stand is new DNA and the other contains a newly synthesized strand.
