coldgirl [10]

The carrying capacity for a species in an ecosystem is primarily determined by the resources in the ecosystem.

<u>Explanation:</u>

The availability of food, raw materials, water and other resources in that ecosystem are those factors that is used for the determination of the carrying capacity. The factors such as nature, the levels of wastage accumulation, removal of very important things from the system also determines the carrying capacity. a system's carrying capacity may involve matters such as available supplies of food, water, raw materials, and/or other similar resources.

The main components that determines the carrying capacity of an ecosystem are food and other resources, provided, the humans must not disturb the ecosystem for their self survival. The resources limitations and their availability determines this factor to a greater extent.

Consider the mRNA wheel. mc022-1.jpg Which amino acid is coded for by the mRNA codon UAA? start codon stop codon Leu Asn

Temka [501]

Attached is an example of a mRNA wheel.

The codon UAA codes a stop codon. The mRNA wheel is read by starting to choose from the four letters at the centre the one that is the first in the codon. Then, on that quarter of the circle, choose from the four letters, the second in the codon. Repeat again the process for the 1/16 part you chose previously choosing now the last letter in the codon. You are now able to identify what is coded by the mRNA codon.
