Answer:
O True
Explanation:
Ecosystem engineers are able to modify the surrounding environment, either by creating new habitats or modifying/destroying existing ones to adjust them to their needs. These species can significantly alter their environments, having a large impact on the species richness as well as modifying the availability of abiotic factors (e.g., water, space, etc) of a particular area. In certain environments, ecosystem engineers can even act as keystone species. Some examples of ecosystem engineers include, among others, beavers, woodpeckers, corals, etc.
Answer:
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.
Answer:
Explanation:
It is carbon because its used to build macromolecules
The correct answer is option C, that is, behavioral isolation.
The phenomenon of behavioral isolation takes place when two populations possess the tendency of interbreeding, but exhibit distinctions in courtship rituals or other kinds of behavior. For example, the western and eastern meadowlarks are very identical birds whose habitat overlap in the middle of the United States.
However, the members of the two species will not mate with each other, possibly as they use different songs in order to fascinate males. The eastern meadowlarks will not respond to the songs of western meadowlarks, and vice versa.
Answer:
RNA Polymerase plays an important role in the process called transcription which result in the in the synthesis of RNA from DNA molecule.
Explanation:
RNA polymerase helps in the addition of ribonucleotides in the growing RNA strans that is synthesized from template DNA .
one ribonucleotide is joined to the adjacent ribonucleotide by the formation of phosphodiester bond.
RNA polymerase is named so because this enzyme helps in the polymerization of ribonucleotides leading to the formation of a Primary RNA transcript.
