The answer would be: <span>A viral load of 1,200 copies/mL
</span>
Viral load determines the number of HIV virus that can be found in every mililiters of blood. More virus means more risk of <span>transmission</span>. A vaginal delivery will cause much more blood than cesarean delivery. The contact of the blood and the baby cause vaginal delivery is more dangerous than cesarean.
Answer:
if the results are efficient in answering the problems raised in the research and if they manage to come to terms with the hypotheses.
Explanation:
As you may know, scientific research must be done through several steps that allow an experiment to be carried out in order to reach conclusions on a certain topic.
In research on the carbon cycle and global warming, it is necessary for the researcher to raise problems and questions about this topic, as well as to raise hypotheses that must be directly related to the results of the experiment. If the result of the experiment is efficient in answering the research problems and questions, in addition to being able to agree with the presented hypotheses, it means that the research has value within the scientific branch in which it fits, in addition to showing that the experiment was done correctly.
The options for this question are:
- Requires genetic variation
- Results in descent with modification
- Involves differential reproductive success
- All of the above
Answer:
<u><em>The correct option is d) All of the above</em></u>
Explanation:
The theory of natural selection explains that genetic variations occur in organisms of a species. Those organisms which are better adapted to live in an environment are able to survive and pass on their characteristics to their offsprings, hence descent with modification. Through this phenomenon, evolution takes place with the passage of time. Natural selection favours survival of the fittest. Hence, all of the above statements are true.
Answer:
One significant difference that I noticed was the color of the water. In the control aquarium, the color of the water at 30 days was the same as it was on the 1st day. In the experimental aquarium, the water had a green tint on the 30th day, but on the first day it was clear.
The main function of white blood cells is to help protect the human body from infection as well as other foreign materials. White blood cells are also known as leukocytes, and they develop in bone marrow from stem cells. There are five different types of white blood cells<span>, including neutrophils, lymphocytes, monocytes, eosinophils and basophils.</span>
