<span>Ecosystems are named according to the vegetative inhabitants of the ecosystem which means that the answer is B. by the plants that inhabit the ecosystem. The plants themselves however depend on the climate that is found in the place where they are found, which means that they wouldn't be able to thrive and spread in any other ecosystems.</span>
In the deep layers of the ocean, various distinct kinds of species are found like fangtooth fish and vampire squid, to sea urchins and coffinfish.
One of the probable adaptation, which is not fully understood in the deep sea is gigantism. This refers to the ability of animals to become highly enormous in size. A well-known illustration is a giant squid, and others, like giant isopod, the kings of herrings selfish, and the colossal squid.
One of the possible reason of gigantism is the tendency of the species in the deep sea to live for long years, that is, for decades or for even centuries. As food is not abundant in the deep zones, thus deep sea creatures have evolved some interesting mechanisms of feeding.
In the non-existence of photosynthesis, the majority of food comprises of detritus, that is, the decaying leftovers of algae, microbes, animals, and plants from the upper layers of the ocean. Apart from that, the corpses of large animals, like whales that sink to the bottom give irregular but huge feasts for deep-sea animals.
Answer:
a. True
Explanation:
Bruce Wallace was a professor emeritus of genetics who performed many population studies. He worked in 1958 at the University of Cornell as a professor of genetics. In 1963, he performed a population study wherein the recessive allele <em>It </em>was at a frequency of 0.5. The population was propagated for 10 generations and the frequency of <em>It</em> for each generation was determined.
The result of this study showed that<em> lt/lt </em>died without reproducing, whereas, individuals with genotype <em>+/+ </em>were normal.
The mechanoreceptor that is located deeper in the skin and responds continuously to stimulation and is associated with perceiving stretching of the skin is called Ruffini corpuscle.
Mechanoreceptor is a sensory receptor that responds to mechanical pressure. They are connected with sensory neurons that convert this mechanical pressure into electrical signal. It is of four types-
1. Merkel corpuscles- detect pressure and roughness on skin.
2. Ruffini corpuscles- detect deep tension in skin, skin stretch.
3. Meissner corpuscles- perception of light touch and slip on skin.
4. Pacinian corpuscles or Vater-panician corpuscles- detect rapid vibrations.
When these receptors sense a stimuli they gets excited and generates an impulse that travels through the nerve cells into the brain.

The four major types of germs are bacteria, viruses, fungi, and protozoa. They can invade plants, animals, and people, and sometimes they can make us sick.
