Answer:
Groundwater is all the water that has penetrated the earth's surface and is found in one of two soil layers. The one nearest the surface is the <u>"zone of aeration"</u>, where gaps between soil are filled with both air and water. Below this layer is the "zone of saturation", where the gaps are filled with water.
Explanation:
Groundwater is the water found underground in the cracks and spaces in soil, sand and rock. It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers.

The specific action of an enzyme with a single substrate can be explained using a Lock and Key analogy first postulated in 1894 by Emil Fischer. In this analogy, the lock is the enzyme and the key is the substrate. Only the correctly sized key (substrate) fits into the key hole (active site) of the lock (enzyme).
Smaller keys, larger keys, or incorrectly positioned teeth on keys (incorrectly shaped or sized substrate molecules) do not fit into the lock (enzyme). Only the correctly shaped key opens a particular lock. This is illustrated in graphic on the left.

Natural selection relates to adaptations except for Natural selection grants a species any trait it might need for survival
Explanation:
The ways in which an organism adapt to its changing environment is termed as natural selection. The individual with better trait compatible to the environment adapt themselves and reproduce to pass on the useful trait to its offspring. Through the process of natural selection, population survives.
Natural selection is also responsible for speciation where new species can occur in population.
If the environment changes rapidly, some of the species are not able to adapt
and eventually gets deleted from the environment.
Natural selection itself does not provide any trait to the species or population it is just a way how species adapt with traits they inherited over a period of time.
This is an example of behavioral isolation. This is an important evolutionary mechanism that helps members of similar species to identify each other as proper mates. It is based on the behavior of species in the context of mating signals and rituals.
Answer:
The correct answer is "pollinator".
Explanation:
Insects are the first animals that come to mind when we think about pollinators, however hummingbirds are an excellent example of pollinators as well. Hummingbirds feed frequently from flowers, transferring grains of pollens from a flower to others. Some species of flowers have adapted to develop some traits to attract hummingbirds, such as certain color, shape and scent.
