Answer:

It can form four bonds. It is small and can form long chains

Explanation:

The carbon atom has specific properties that enable it to form covalent bonds to as many as four separate atoms, rendering this flexible factor suitable as a simple structural part.

How can the ethiopian wolves prey be classified as.<br><br> Dont say endangered plz

TEA [102]

Given what we know about the diet of the Ethiopian wolves, we can confirm that their prey can be classified as rodents.

<h3>What are Ethiopian wolves?</h3>

The Ethiopian wolves are a canine native to Ethiopia.
They are carnivores and hunt in packs.
Despite their name, they more closely resemble foxes or jackals.
They feed on rodents such as rats and hares.

Therefore, given their diet based primarily on animals such as hares, giant mole rats, and grass rats, we can confirm that the prey of the Ethiopian wolves can be classified as rodents.

Answer:

The nucleic acid is a macromolecule present in living systems in the form of either DNA or RNA, whose molecule consists of many nucleotides which are linked with each other to form long chains. The presence of DNA or RNA in an individual promotes continuity of life. The variability and complexity of nucleic acid are dependent on its constituent molecules as, sugar, a phosphate group, and a nitrogenous base. However, two monocyclic nitrogenous bases were classified purines (adenine:A, guanine:G) and pyrimidines (thymine:T, cytosine:C, and uracil:U).

In addition, RNA is a single-stranded structure which differs from DNA in two aspects, the sugar content of RNA is ribose, and pyrimidine base uracil replaces the thymine base of DNA. A ratio between two strands of DNA can be calculated by using Chargrff's rule which states that "DNA from any cell of all organisms possess a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases'.

The purine to pyrimidine ratio in RNA with different bases is given below in the following table:

Presence of single strand in RNA does not follow chargaff's rule and alters the purine: pyrimidine ratio. The above ratio of each base in the given information is not equal, due to which the ratio of purines to pyrimidines is different. The ratio of DNA and RNA is not equal because DNA has its complementary DNA strand. However, bases in RNA might vary due to its single-strandedness property, but its ratio is dependent on the species.

Therefore, it can be concluded that the ratio of purines to pyrimidines is dependent on the species due to its genetic makeup. Hence, option (c) is correct.
