Answer:
Option B, an allosteric inhibitor.
Explanation:
As the enzyme activity decreases, it is not possible for A to be a coenzyme (most likely would increase the enzyme activity), a substrate (increases activity of enzyme by Le Chatler's principle) or an intermediate (no effect). A is unlikely to be a competitive inhibitor as this would not decrease the activity of the enzyme, only reduce the rate of conversion of substrate to product. A is most likely an allosteric inhibitor which binds to another site on the enzyme (other than the active site), resulting in a change in conformation of the enzyme which reduces the enzymatic activity.
Answer:
A. Hepatitis B
Explanation:
Hepatitis B is a disease caused by a virus.
Hepatitis B is passed from person to person from bodily fluids.
Tuberculosis, Tetanus, and Strep throat is caused by bacteria.
Answer:
Chordates
Explanation:
Chordates (phylum Chordata) include the vertebrates, together with several closely related invertebrates.
Sexual reproduction produces far more genetic variation than asexual reproduction. I’m asexual reproduction, only one organism is needed. In this process they copy their own DNA and create an exact copy of themselves. So, if you think about it, all the offspring ever created by that one organism is going to have the same genetics as it. They’re all going to be identical. There is no variation, or differences, between any of the offspring and the original organism. Bacteria reproduces this way, although through binary fission, they can sort of reproduce sexually.
Sexual reproduction results in genetic variation. Two organisms are needed to create offspring. An egg cell and a sperm cell are needed from a female and male organism to create the new organism. Since two organisms are required, their offspring will be a mix of their DNA. This will create variation between offspring. Every new organism will have different genetics.
This is why more advanced organisms like plants and animals have different DNA even if they are the same species.
