Answer:

including other cells, by enclosing the particles in an extension of the cell membrane and budding off a new vesicle. During pinocytosis, cells take in molecules such as water from the extracellular fluid. Finally, receptor-mediated endocytosis is a targeted version of endocytosis where receptor proteins in the plasma membrane ensure only specific, targeted substances are brought into the cell.

Explanation:

so the answer is exocytosis

Boris Magasanik collected data on the proportion of each base in RNA from different species. To compare the relative amount of e

just olya [345]

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.

Imagine a scenario where Barr bodies are not due to random inactivation, but rather, the silencing is due to paternal imprinting

artcher [175]

Answer:

<h2>If Barr bodies are not due to random inactivation, but rather, the silencing is due to paternal imprinting then the frequency of men and women differs. </h2>

Explanation:

Red-green color blindness: color blindness is an X-linked recessive disorder. The male having this disease will transmit his X chromosome (with the mutation) to his daughter, who will then be a carrier of the disease.

If Barr bodies are not due to random inactivation, but rather, the silencing is due to paternal imprinting then the frequency of men and women differs.

Male inherit its X chromosome only from mother and no X chromosome from father, having one Y chromosome but female receive one X chromosome from father and one from mother, having no Y chromosome, So if the paternal allele is silenced then the males are no affected.

Use 2-3 sentences to describe what would if populations never evolved?

s2008m [1.1K]

Answer: Well, populations never evolved than one human might have gone extinct due to many different viruses and sicknesses but other animals might not be extinct. If populations never grew more then that would be because we could not overpower dome viruses. If we never. If we never evolved animals like a Carrier pigeon would not be dead or extinct today.
