Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by dwarf shrubs close to the ground.
Answer:
D. decreasing in population.
Explanation:
Triggerfish are the brightly colored fish and sea urchins are the globular animals, echinoderms. Triggerfish eat sea urchins for their survival.
An increase in the use of recreational boats over the area will damage the habitat of the triggerfish and also affect their food supply, it will result in a decreasing population of triggerfish. Due to lack of sea urchins and habitat disturbance, the Triggerfish population will decrease
Hence, the correct answer is "D. decreasing in population."
Answer:
D.Competitive inhibition will decrease because the proportion of the active sites occupied by substrate will increase.
Explanation:
Methyl alcohol is a competitive inhibitor of ethyl alcohol. This means that both of them compete with each other for the same enzyme (ADH). Methyl alcohol leads to poisoning because it is converted to toxic formaldehyde in body. It can be treated by increasing the concentration of ethyl alcohol.
More ethyl alcohol (substrate) will reduce the competitive inhibition by methyl alcohol (inhibitor). This will happen because a substrate needs active sites on an enzyme to attach to it. If ethyl alcohol is increased in concentration, it will occupy more active sites and their availability to methyl alcohol will be reduced. Thus, the enzyme will not be able to act on methyl alcohol.
Answer:
The correct answer will be option- A and D
Explanation:
<em>E.coli</em> is a bacteria which is pathogenic to humans and<em> E. histolytica</em> is an amoeba which is a parasite. Both are different species but both are single-celled organism which to survive share feature among them.
The common characters shared by these two species are: they depend on the source of energy for their survival which they usually get from the hosts.
Both the species reproduce to produce progenies like them which help them maintain continuity of the species of Earth.
Thus, options- A and D are the correct answer.
