A design of growth in which (occurs only in a different situation), the population frequency of an organism rises gradually originally, in a good acceleration time, later progresses swiftly nearing an exponential growth pace just like the J-shaped curve, however, it later declines (meaning rejects) in a bad acceleration time till at zero growth rate the population maintains. For example, yeast is a tiny fungus, so tiny, a microscope is required to view it, furthermore, it is used to produce bread and alcoholic drinks, displays the traditional S-shaped curve if raised in a test tube. Its maturity levels off as the population deplete the nutrients that are essential for its growth.
<span>Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.</span>

Long before chromosomes were visualized under a microscope, the father of modern genetics, Gregor Mendel, began studying heredity in 1843. With the improvement of microscopic techniques during the late 1800s, cell biologists could stain and visualize subcellular structures with dyes and observe their actions during cell division and meiosis. With each mitotic division, chromosomes replicated, condensed from an amorphous (no constant shape) nuclear mass into distinct X-shaped bodies (pairs of identical sister chromatids), and migrated to separate cellular poles.
Answer:
Grinnell was the scientist who coined the term niche. An ecological niche the place where the species and their members live together. Niche is quite different from habitat.
Niche include all the things which have impacts on a population and population impact on its environment and other species in their area. So the ecological niche does not mean the volume of area a species occupies but also include its specific functional role in its community.
For example, a lake can be considered as a habitat for fish but a lake can provide a different niche for fishes. A big fish hunting a small fish in a portion of a lake is a niche and a small fish hunting an insect in another portion of the lake is another niche.
