Answer:
biochemical compound
Explanation:
A biochemical compound is any compound that contains carbon and is found in
living things. They're involved in every process of life, including growth, digestion,
respiration, you name it. There are four classes of biochemical compounds :
carbohydrates, proteins, lipids (fats), and nucleic acids.
Answer: A. Extirpation
Explanation:
The term extirpation is also known as local extinction. It is situation whereby a particular species ceased to exist in an environment where it was once found, though it's existence is still observed elsewhere.
Extirpation maybe as a result of unfavorable environmental and human factors such as hunting, food scarcity and climate variation.
Answer:
True
Explanation:
There are several types of cytokines used in cell signaling; interferons, interleukins, tumor necrotic factor, and chemokines. T helper cells mainly produce interleukins. When activated by Antigen-Presenting-cells, t-helper cells produce interleukins that activate B cells and is significant in their proliferation during an infection.
Answer:
Because of niche partitioning or differentiation.
Explanation:
Competition is a common ecological and evolutive process in nature. Competition might be intra- or interspecific. Competition between different species in a community or ecosystem might be due to the same resource use, or the same territory, shelter, etcetera. When a resource is useful for two or more species and limited, they compete to gain it.
The <u>principle of competitive exclusion</u> states that different species with the same requirements sharing the niche can not coexist indefinitely based on the same limited resource. <u>When two competing species coexist, this is because of niche partitioning or niche differentiation.</u>
Differentiation of effective niche is closely related to character displacement. Resource partitioning and differentiation allow both species to coexist more effectively.
In the exposed example, swallows and bats feed on insects and breed in similar habitats. However, swallows feed during the day, while bats feed during the night. Feeding at different times is an example of niche differentiation. In this way, both species can inhabit the same area and feed on the same source of food, but avoid competition.
