Answer:

Alveoli

Explanation:

Bronchioles end in tiny air sacs called alveoli, where the exchange of oxygen and carbon dioxide actually takes place. Each person has hundreds of millions of alveoli in their lungs. This network of alveoli, bronchioles, and bronchi is known as the bronchial tree

A grassland is experiencing a severe drought. The lack of rain is causing the grass to die and the ponds and creeks to dry up.
dusya [7]

The population of fish will decrease.

The population of grazing animals will decrease.

<h3>What is drought?</h3>

A drought is a prolonged period without enough precipitation/water to support people, animals or crops.

With less water, fish and other creatures have fewer places to dwell, swim, and evade predators. In the near run, shrinking streams and lakes necessarily result in fewer fish. Drought conditions can cause water temperatures to rise, affecting cold-water species such as native trout.

The population of grazing animals would decrease as the grass is a food source and without their food source, there would be no source of staying meaning that they would result to finding new food sources through migration likely.

Climate changes can produce various effects in ecosystems. Which of the following is a way that marine ecosystems can be affecte
Darya [45]

Since the speed of many physiological processes in marine organisms is determined by the temperature, the first consequence of the changes in the conditions of the medium becomes offset the timing of seasonal events, such as the timing of spawning fish. There have also offset migration routes and spawning areas. So, as a result of warming in the Sea of ​​Japan, spawning navaga shifted to an earlier date, because of the reduction of the area of ​​"cold spots" in the eastern Bering Sea shelf feeding migration of pollock, halibut and crab are lengthened, but because of the temperature rise to the east of Japan, spawning saury expanding. These changes significantly affect the success of reproduction, resulting in changes populations of their fishery.

An allosteric protein demonstrates a decrease in its Kg for molecule Y as the concentration of molecule X increases. Based on th
djyliett [7]

Answer:

X is negative heterotropic modulator

Explanation:

In allosteric regulations, modulators are molecules that causes a change in the conformation of an enzyme, hence, resulting a change in enzyme activity. It can lead to a decrease or an increase of the enzyme.  When a molecule decreases the enzyme activity it called a negative modulator, when it increases or activates the enzyme activity, it is called a positive modulator.

A positive or negative modulator can either be homotrophic (substrate acts as modulator) or heterotropic (another ligand acts as modulator).

In the example above, X is negative heterotropic modulator, because the modulator is different from the substrate and it also decreases the enzyme activity.
