The first blank is hypertonic and the second blank is hypotonic
The rungs are composed of hydrogen bonded paired Nitrogenous Bases. These pairings are Adenine to Thymine and Guanine to Cytosine.
Answer:
B. Sea stars are the prey of seagulls
Explanation:
Seagulls eat sea stars, meaning that sea stars are their prey (the organism that is eaten).
Predator: an organism that eats (preys on) another organism
Prey: an organism that is eaten by another organism (creatures can be both predator and prey. For example, a rabbit is a predator to grass, while they are prey to foxes)
Host: An organism that is fed on by a parasite. Think of a dog with a tick. The dog is the host, the tick is the parasite.
Incorrect answers (and why):
A. Sea stars do not eat seagulls
C. If a sea star was a predator to a seagull, that would mean that they eat seagulls. They do not.
D. A host is an organism that a parasite preys on. Not only are sea stars not parasites, but they definitely do not prey on seagulls.
I hope this helps! :)
Answer: Enzyme compartment cannot be used as metabolic control mechanism.
Explanation: Metabolic control or regulation employs many substrates,enzymes and byproduct to send a signal to cells to perfom or stop perfoming certain duties. Too much glucose for instance will regulate, activate and send signals using insulin to store glucose in form of glycogen using the process of glycogenolysis. Hormones and enzymes will also signal to activate the process of sleep, menstruation, digestion etc activating and regulating different kind of cells.
On the other hand enzyme cormpartmentation is there to maintain order and protect cells from lysis by making sure that each enzyme and cell works in its own confined space.
