Obsidian is an extrusive rock that is formed when magma from underneath the Earth's crust breaches and becomes lava. Once the lava starts cooling, it solidifies and elements are frozen, giving the rock its glassy appearance.

A inhibitor of carbonic anhydrase would:______
Naily [24]

Answer:

c. increase blood pH.

d. interfere with oxygen binding to hemoglobin.

Explanation:

A inhibitor of carbonic anhydrase increases the pH of the blood due to prevent the production of carbonic acid from the carbon dioxide formed during cellular respiration. This carbonic acid decreases the pH of the blood so inhibitor of carbonic anhydrase is responsible for the increase in the pH. It also interfere with oxygen binding to hemoglobin because oxygen bind with hemoglobin in low pH but the pH is higher due to inhibitor of carbonic anhydrase.

Which graph most likely represents a rabbit population that found a new, larger habitat, but then eventually experienced an
klio [65]

The graph will have a sharp curve in upwards manner when the new, larger habitat is found, but than will be followed by slight decrease when the predation increases.

Explanation:

If a population of rabbits finds a new, larger habitat, than the population will experience rapid rise, especially if there isn't high scale predation on them. This will be due to the abundant food resources, but also because of the fast reproduction of the rabbits. The low predation will mean that most of the rabbits will survive, so the numbers will be on the rise.

When the population starts to experience in increase in predation, the situation changes. The larger number of predators means that they would need much more food, so much more rabbits will be killed and consumed by the predators. This will stop the population rise, and it will either stagnate, or most probably it will experience slight decline.
