The disease is spread from chimpanzees, who are infected with a very dangerous virus that induces rage. These infected chimps are held captive in a laboratory, but a group of animal activists sets out to liberate them. So, they get infected too, and spread the infection further.
Answer:
B) binding of a molecule to a binding site affects the binding properties of another site on the protein.
Explanation:
In an allosteric interaction between a protein and a ligand, the ligand binds to a site in the protein. As a result, there is a change in the properties of other active sites on the protein. These active-site changes may or may not allow the protein to bind to other molecules. There is a change in the protein that affects the affinity of the active site for other molecules. The affinity on the active site increases if the protein binds to an activator and decreases if the protein binds to an inhibitor molecule.
Birds have great vision and can see throughout night and day
Answer:
1) By 11:30pm
2) Shortly before midnight (few minutes to 12:00am)
Explanation:
Since the strain of bacteria takes 1 minute to divide (double its population), and by midnight (12:00am) the entire bottle becomes full, then:
I) Subtract Initial division time from Final division time i.e 12:00 - 11:00 = 1 hour
II) Split 1 hour into two (60minutes makes 1 hour)
I hour/2 = 30 minutes
Definitely, the bottle will be half filled by 11:30pm
2) Once half filled, the rapidly dividing cells reach for the top of the bottle as midnight approaches. By 11:50pm upwards, bottle space must have been running out
Answer:
B
Explanation:
The structure of the mitochondrion is key to the process of aerobic (in the presence of oxygen) cellular respiration, especially the Krebs cycle and electron transport.
