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:

Provides both the RNA and the polymerase needed for synthesis

Explanation:

Telomerase is an enzyme which extends the telomere sequences present at the end of the chromosomes. The telomerase enzyme acts as DNA polymerase as well as provides the RNA which serves as a template strand rather than the primer.

The polymerase acts as a reverse transcriptase enzyme and synthesizes the DNA strand from the  RNA template. Since the telomerase provides RNA and acts as DNA polymerase, therefore, it is known as the ribonucleoprotein molecule.

Thus, the selected option is correct.

What is the different between mechanical digestion and chemical digestion in the mouth?
Alborosie

Answer and Explanation:

The mouth is part of the digestion system.

Mechanical Digestion is the physical motion our mouth makes to chew up the food. We grind up the food with our teeth, then swallow the food into the next part of the digestive system.

Chemical Digestion in the mouth is the saliva our mouth produces. It breaks down the food along side the mechanical part of the mechanical digestion.
