Answer:
Explanation:
The charge of an atom is the number of protons minus the number of electrons. Usually, these two numbers are equal, so the atom is neutral (charge of zero). Answer 8: An atom is defined as having the same number of electrons (negative charge), protons (positive charge) and neutrons (no charge).
Answer:
c) The largest problem is that single viruses may create multiple plaques, resulting in overestimates of the number of viruses present.
Explanation:
- Plaque-based assays are the accepted method used for finding virus concentration in terms of infectious dose.
- Viral plaque assays determine the number of plaque forming units (pfu) in a virus sample, which is one measure of virus quantity.
Answer:
Letter b. Gluconeogenesis
Explanation:
Immediately after eating we use the sugars in the food and utilize for energy and last a couple of hours. After that and about 15 hours later our body uses the energy stored in the liver in the form of glycogen, a process called glycogenolysis, that is the action of breaking the glycogen to free the energy. After 24 hours, the body starts to use another molecule for energy like fatty acids and start to synthesize glucose from other precursors, this process is called gluconeogenesis, and fuels the vital organs like the brain to maintain its function.
