Species richness increases _____. Group of answer choices as we increase in altitude in equatorial mountains as community size d

erica [24]

Species richness increases as we travel southward from the North Pole.

Explanation:

Species richness is at its highest in places near or surrounding the equator and reduces gradually towards the poles. As one travel towards south from the northern pole, the temperate, tropical and equatorial regions will be reached where there is huge diversity of species.

Be it the tropical rain forests, the Amazon forests, or the deciduous forests, they are highly rich in their species population and variety. This is mainly due to availability of favorable conditions like weather, temperature, rainfall, etc which favors their growth and reproduction. Numerous phyla or classes of species can be found in such equatorial belts rather than in the north or the south pole.

Elevation gradient also plays an role in species richness.

A marine biologist measured the amount of heat radiated from an aquarium over the course of an experiment. His measurements are

Andrews [41]

Answer:

The correct answer is - A closed system exchanges all of its energy with its surroundings, and the scientist only measured the exchange of heat.

Explanation:

The amount of heat radiated is measured and analyzed by the marine biologist in this given experiment from an aquarium and on the basis of data the diagram is represented that states that the radiated energy is not constant over time and there are fluctuations.

It can not be considered as a closed system as energy is still exchange with the surrounding system, however, mass is not exchange but still, it cannot be called a closed system.

The venom of the Eastern diamondback rattler and the Indian cobra contains phospholipase A2, which catalyzes the hydrolysis of f

faust18 [17]

a) Lysolecithins refers to the compounds, which are obtained from phosphatidylcholine, it is amphipathic in nature and comprises both the hydrophobic and hydrophilic regions.

On the basis of the composition of a lysolecithin, the choline, glycerol, and phosphate are hydrophilic in nature, while the fatty acid on C1 is hydrophobic.

b) Phospholipase refers to an enzyme, which functions on phospholipids and discharges fatty acid from the 2nd carbon of glycerol resulting in the formation of common arachidonic acid and lysophospholipids.

The phospholipase A2 comprises 15 groups out of which four are very essential, that is, cellular phospholipase A2, secreted phospholipase A2, calcium-independent phospholipase A2, and lipoprotein-associated phospholipase A2.

They perform essential functions like pro-inflammatory activity, antimicrobial actions, bone formation, insulin secretion, apoptosis, axon regeneration, sperm development, and also function as markers of coronary heart disease.

The molecular clock has limited usefulness for estimating divergence times among species in part due to the saturation of DNA se

Greeley [361]

Answer:

In highly diverged lineages, the substitutions process will occur at sites that have been substituted previously.

Explanation:

Molecular clock uses the mutation rate to reduce the time in prehistory when the life forms are diverged. The molecular clock uses the sequence of amino acids and nucleotide sequence for the DNA.

This clock does not measure any time but the number of mutations, and other changes over certain time. Sometimes its useful property might be limited due to the highly diverged lineages.
