We alter carrying capacity when we manipulate resources in a natural environment. If a population exceeds carrying capacity, the ecosystem may become unsuitable for the species to survive. If the population exceeds the carrying capacity for a long period of time, resources may be completely depleted and Then the population size remains relatively the same. If abiotic or biotic factors change, the carrying capacity changes as well. Natural disasters can destroy resources in an ecosystem. ... If a population exceeds carrying capacity, the ecosystem may become unsuitable for the species to survive.
Explanation:
Frontal lobe
Frontal lobe is situated near the front of the head and it is the most forward of the four lobes of the cerebral cortex. The frontal lobe is the area responsible for primary motor functions and some of the most complex cognitive processes such as memory, problem solving, sexual behaviors, emotional expression, language, and judgment.
Tiktaalik is a transitional fossil which shows how fish evolved into amphibians and reptiles. So the correct option is B.
What is Tiktaalik?
Tiktaalik is a direct ancestor of tetrapods or four-legged animals. It is an extinct fish-like animal and it lived on earth 380-385 million years ago (Devonian period).
The word Tiktaalik is derived from the <em>Inuktitut</em> language which loosely translates to large freshwater fish. This animal had characteristics of both fish and tetrapod and is therefore called the link between these two kinds of animals.
The characters resembling fish are gills and scales and the characters resembling tetrapods are rib bones, movable neck and lungs. There are characters that are a mix of both tetrapods and fish. These are bones and joints in limbs but fish-like fins instead of feet or hands.

The larger vacuole in the plant helps the structure of the plant more. An example would be when you see a not watered plant and it looks droopy. It's because the vacuole has no water or waste in it to help with the structure. Plus, the vacuole is able to contain more in a plant cell. This is needed because animals can go get water or food when they need it, but plants are stationary and they have to use what they have stored.
