Answer:
<em>The total amount of energy transferred during photosynthesis for this ecosystem equals</em><em> 260,000 kcal/m2/yr.</em>
Explanation:
To answer this question, we need to know that
- gross primary productivity (GPP) = energy captured and converted into chemical energy during photosynthesis
- net primary productivity (NPP) = difference between GPP and respiration rate
So, to calculate GPP we need to sum NPP to Respiration rate. This if,
NPP = 165,000 kcal/m2/yr
R = 95,000 kcal/m2/yr
NPP = GPP – Respiration
Then,
GPP = NPP + R
GPP = 165,000 kcal/m2/yr + 95,000 kcal/m2/yr
GPP = 260,000 kcal/m2/yr
Based on the CDC guidelines a person with a CD4+ cell count between 200-400 is regarded as being in <u>the second stage</u> of the HIV infection.
Acquired Immunodeficiency Syndrome
Acquired immunodeficiency syndrome (AIDS) is a condition caused by HIV (human immunodeficiency virus). AIDS is a chronic disorder and can become life-threatening for the infected person. The HIV viruses reproduce inside the host and while doing so they destroy the CD4+ immune cells which reduce the person's ability to fight against other diseases.
CD4+ cell count and AIDS
According to the CDC (U.S. Centers for Disease Control and Prevention), HIV infection is categorized into different stages based on the number of CD4+ cells.
- Stage 1: - CD4+ cell count is more than 500 per microlitre. There are no symptoms or AIDS-related conditions.
- Stage 2: - CD4+ cell count is more than 500 per microlitre. There are no symptoms or AIDS-related conditions.
- Stage 3: - The CD4+ cell count falls below 200 and AIDS-related symptoms and conditions are present.

Phillip is the father as the baby has a heterozygous blood type B which is IBI in order for this to have happened the IB part would have came from the baby’s mom and the I or blood type O part would have came from the baby’s dad. However because blood type O is recessive blood type B is dominant and is show.
