A because in protein synthesis you need proteins and ribosomes make proteins

Answer:

A. ribosomes, rough endoplasmic reticulum, Golgi apparatus

Explanation:

Protein synthesis is a rapid process that occurs in all cells of the body, more precisely in ribosomes, organelles found in the cytoplasm and the rough endoplasmic reticulum. Golgi complex is also an organelle related to protein synthesis, since among these functions we can mention the processing of lipids and proteins.

For this reason, we can say that the correct answer to your question is the letter A.

8. In a population of beetles, there is a gene for color with two codominant alleles. The allele R leads to red beetles and the
Eddi Din [679]

Answer:

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

Explanation:

Given that:

The allele → R = Red beetles

The allele → B = Blue beetles

Since the gene color shows a codominant allele

The Red Beetle = RR

The blue beetles will be = BB

The heterozygous beetle will be = RB

∴

The punnet square showing the crossing of RB × RR is:

                R                   B

R                RR               RB

R                RR               RB

The result shows that we have two red beetles and two heterozygous beetles.

Hence;

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

In nature during 24-hour period what substance do green plants continuously use
almond37 [142]
<span>Plants take in oxygen all the time for respiration.
Photosynthesis which begins by combining water and CO2, continues in the "dark phase" in making the glucose molecule. Light is not used for this part of the reaction so it is called dark , because light is needed for the first part.

What type of bonds form between the nitrogenous bases? Why are these bonds important?
Bond [772]

Answer:

The bonds that are formed between nitrogenous bases are Hydrogen Bond.

Explanation:

When a hydrogen atom interract with an electronegative atom such oxygen,fluorine hydrogen bond forms,

              A single hydrogen bond is weak noncovalent bond but collectively they exerts  very strong interraction.

            Hydrogen bonding occurs between complementary base pair .For exam An adenine base forms 2 hydrogen bonds with thymine base whereas guanine forms 3 hydrogen bonds with cytosine base.

             The hydrogen bonding between complementary is very much important to stabilize the structure of DNA .
