Answer: option D.

Phenotype

Explanation:

Theory of natural selection shows that different organism survive, adapt and reproduce in their environment due to their different phenotypic variation. The phenotypic variation exist among individual organisms and it is heritable which is transfer from one generation to another.

Phenotype are traits or physical characteristics or observable characteristics of organism e.g organisms appearance, behavior e.t.c.

Answer:

d. phenotype

Explanation:

<em>Natural selection exert pressure on the physical characteristics of organisms, that is, the phenotype.</em>

Natural selection refers to the variation in the survival and reproduction of individuals within a population based on how adaptable they are to the environment in which they live.

<u>The forces of natural selection act on the physical characteristics of individuals, that is how physically fit or unfit individuals are. Individuals that posses physical characters that makes them to be better adapted to the environment survives and reproduce better than their counterparts that are less adapted. Natural selection thus selects for the physical characters that make the individuals to be better adapted.</u>

The correct option is d.

List the types of RNA, and explain how the structure of RNA differs from the structure of DNA.
boyakko [2]

Answer:

   The types os RNA are: Messenger, ribosomal and transporter RNA and the difference between DNA and RNA are: DNA has deoxyribose as sugar, RNA has a ribose. The nitrogenous bases present in DNA are cytosine, guanine, adenine and thymine. In RNA, cytosine, guanine, adenine and uracil are found. DNA has two strands, but RNA is single stranded.

  In fact, the DNA has a genetica material like a genetical mensage and it must be translate and deciphered in proteins, many of which will act on the metabolic reactions of the cell. The message contained in DNA should initially be passed on to RNA molecules, which in turn will guide protein synthesis.

Explanation:

 Now talking about each types of RNA separately. The first one I am going to write about is RNA messenger. This type of RNA is of intermediate molecular weight and acts together with ribosomes in protein synthesis. The second one is ribossomal RNA. It is the largest molecular weight and major constituent of ribosome, an organoid related to protein synthesis in the cell. The last one is transporter RNA. It is the lightest of the three and tasked with transporting the amino acids that will be used in protein synthesis.
