(a) What cell structures best reveal evolutionary unity?

Biology
1 answer:
xeze [42]3 years ago
7 0

Answer:

The correct answer will be-

1. Evolutionary unity-  DNA

2. specialized cellular modifications- plant cells have chloroplasts and large central vacuole.

Explanation:

<u>Case I </u>

Evolutionary unity is a concept which explains that all the organisms possess some common structure or universal structure or molecules.

The best characterized evolutionary molecule is DNA molecule which took the role of genetic material in past and is passed on to the daughter cells and still is made up of the same components which are a five-carbon sugar, four types of nitrogenous bases and a phosphate group. This DNA molecule is present in almost every organism except for a few viruses.

<u>Case II </u>

The specialization of the cellular components depends on the function a cell has to perform which became established in the population. The plant cells depended on the sunlight to prepare food for themselves which was done by the chloroplast organelle which is absent in the animal kingdom.

What is the medical term for inflammation of the nose and throat
marysya [2.9K]

The medical term nasopharyngitis is used specifically to refer to the swelling of the nasal passages (the nose) and the back of the throat.

<h3>What is nasopharyngitis?</h3>

It is associated with the rhinopharynx or nasopharynx, which is the sector of the pharynx that is next to the nostrils and above the back of the throat.

It is an inflammatory condition or a disease that is caused by the action of a virus in the upper respiratory system.

Therefore, we can conclude that the medical term nasopharyngitis is used specifically to refer to the swelling of the nasal passages (the nose) and the back of the throat.

If a mother is type A and has a child who is type B what are the possible blood types of the father​
jenyasd209 [6]

The possible father's  blood groups are B, AB.

<u>Explanation:</u>

If the mother blood type of A, and the father blood type is AB, B then the child is B. Each biological parent donates one of their two ABO alleles to the child. The blood types in our body are classified as the four paternal blood types and the four maternal blood types.

The blood type has the 16 combinations of the blood samples. The genetic information from the body is independently inherited to the ABO blood types alleles. In the Rh factor, the genetic information is inherited from the one parent to another.

Identify how the deletion of a single nitrogen base in DNA can cause a harmful mutation in an organism.
ra1l [238]

Answer:

B. Nearly every amino acid translated after the error will create the wrong protein after the deletion of a base.

Explanation:

Generally, mutations occur in two ways: 1) a base replacement, where one base is replaced for another; 2) insertion or deletion, where a base is either incorrectly inserted or deleted from a codon.

When a nucleotide is wrongly inserted or deleted from a codon, the effects of this change can be extreme. An insertion or deletion can affect every codon in a particular genetic sequence.  For example, given the code:

GAU GAC UCC GCU AGG. It is the codes for the amino acids aspartate, aspartate, serine, alanine, and arginine. If the A in the GAU were to be deleted, the code would become GUG ACU CCG UAG G. It won't produce any right amino acid.

So, if the code becomes changes, it won't produce any amino acid or will produce the wrong amnio acid.
