When new habitat is made available, organisms can diversify rapidly. this can be gradual or punctuated this process called as adaptive radiation.
<h3>What is Habitat?</h3>
The term "habitat" in ecology refers to the variety of resources, physical characteristics, and biotic elements that exist in a region and are necessary for a specific species to survive and reproduce. An animal's habitat can be thought of as the outward representation of its biological niche.
Thus, the term "habitat" refers to a specific species and is fundamentally distinct from ideas like the environment or vegetation assemblages, which are better described by the term "habitat-type."
The physical elements could consist of things like soil, moisture, temperature range, and light intensity, for instance. The availability of food and the existence or absence of predators are examples of biotic variables. Every species has certain habitat needs; habitat generalist species can survive in a variety of environmental circumstances, whereas habitat specialist species need a specific habitat.

Answer:
The correct answer is option D, that is, the elephant will not react.
Explanation:
A kind of behavior that comprises a stimulus-response, which is distinct from the natural one is termed as conditioning. It is a kind of learned behavior. It is a kind of learning where the efficacy of stimulus enhances while provoking a response. When the presentation of two stimuli is done at a suitable time and with appropriate intensity, then one of them will be able to provoke a response that resembles the other one.
In the given case, the mouse and the trombone are termed as unconditioned and conditioned stimuli. When a conditioned stimulus is demonstrated in a context of classical conditioning, it will result in the non-predication of the coming unconditioned stimulus. The conditioned response will get to cease slowly and will eliminate the conditioned fear. Thus, in the given case, the elephant will fail to react towards the trombone subsequently.
Answer: Erythrocytes also known as Red blood cell compose about 40-45% of blood
