All modern primates, including humans, are descendants of the earliest primates.
<span>Amylase needs an optimum pH for its activity. It is in the range of 6-7. Below or above pH will denature this enzyme. The pH level is optimum for this enzyme in the mouth and hence it catalyses the break down of sugar. The pH level of stomach is lower than its optimum level duet to the activity of gastric acid. Hence the enzyme becomes inactive in the stomach.</span>
Explanation:
Natural selection is the mechanism that is responsible for the evolution of organisms.
In the given case, the Freshwater shrimp has been introduced to a pond in which the two species with variations are introduced.
The <em>C. cantonensis </em>is brighter in color whereas the <em>C. multidentata</em> is mottled drab in color. The predator fish can feed easily on the species which is brighter therefore <em>C. cantonensis</em> is more susceptible. The mottled drab species is not easily predated by the species.
The 30 % offsprings of <em>C. cantonensis</em> can survive till the reproductive age whereas 75% of C. multidentata. This shows that natural selection has acted on the color of the shrimp species selected against the predator fish species.
The species with mottled drab color is the result of the differential reproductive rate.
Unicellular - composed of only one cell.
multicellular - composed of multiple cells.
Answer:
<em>The correct option is A) The sundew population would increase. </em>
Explanation:
Organisms in a community interact with one another in some way or the other.
In the above-mentioned example, sundews and wolf spiders of a community are in competition with each other for food resources. If the population of one of the species i.e wolf spider decreases this means that there would be lesser competition for food resources. As a result, there will be more food present for the sundews. Hence, the population of sundews would increase if the population of wolf spider decreases.
