Answer:

1. GCA:arginine

2. AGU:cysteine

3.UAC:Tyrosine

4.AUG:Methionine

The correct amino acids which are encoded by the codons are GCA- Alanine, AGU- Serine, UAC- Tyrosine, and AUG- Methionine.

A codon is a specific three nucleotide sequence of nucleotides such as DNA or RNA which are transcribed on an mRNA that corresponds to a specific amino acid or a stop signal during the process of protein translation in the ribosome of cytoplasm.

In the eukaryotic cells, there are 64 codons of four nucleotide are observed, from which 61 codons codes for twenty amino acids whereas three codes for stop codons or termination codons.

The amino acids which are encoded by the following codons include: GCA- Alanine, AGU- Serine, UAC- Tyrosine, AUG- Methionine. AUG also acts as the initiation codon i.e., it is responsible for the initiation of translation in the eukaryotic cell.

When rocks are exposed to extreme temperatures, high pressures, hot mineral-rich fluids, or, more frequently, some mixture of these conditions, metamorphic rocks are created. These kinds of conditions can be obtained deep within the planet or where plate tectonics collide.

Heat and pressure cause an existing rock to change into a new rock, creating metamorphic rocks. When hot magma hits rock, contact metamorphism takes place. Under the intense heat and pressure produced by tectonic forces, regional metamorphism changes substantial portions of existing rocks.

The majority of metamorphic rocks are formed underground. Extreme pressure and heat are used to produce them. This includes any procedure where heat, force, or the use of chemical fluids change the structure or makeup of a rock while it is still solid.

Answer:

flexion - depression

extension - elevation

adduction - medial rotation

abduction - lateral rotation

Explanation:

Flexion is the process of bending an arm or leg. It occurs as a result of the contraction of the muscles. Depression is a downward movement. Hence, flexion refers to the depression of an arm or leg.

Extension is the process of stretching the body parts. Elevation is an upward movement. Hence, extension refers to the elevation of body parts.

Adduction is the movement of a limb or other part of the body towards the midline or another part of the body. The movement of the limb towards the midline of the body is known as medial rotation.

Abduction is the movement of a limb or other part of the body away from the midline of the body. The movement of the limb away from the midline of the body is known as lateral rotation.

Answer: They are important because they help modify different proteins.

Explanation:

The importance of CDK in the cell cycle is that they are important because they help modify different proteins and CDK are important in the regulation of the cell cycle.

CDKs are important in many reasons as they help in the regulation of the cell cycle. They carry out their function by adding phosphate groups to target proteins. Protein kinases called CDKs (cyclin-dependent kinases) are involved in controlling the cell cycle. The regulatory proteins known as cyclins are responsible for activating the cyclin-dependent kinases. As the cell moves through the cell cycle, the activity of different Cdks rises and then falls.

A cyclin-Cdk complex is created when a particular CDK binds to the associated cyclin. Proteins and other targets are phosphorylated by cyclin-Cdk complexes. Some of these proteins are activated by phosphorylation whereas the others are deactivated. For instance, phosphorylation causes the protein p27 to be broken down. Since p27 is one of the main inhibitors of cell division, low levels of p27 cause cells that aren't dividing to start doing so.

Therefore, The importance of CDK in the cell cycle is that they are important because they help modify different proteins and CDK are important in the regulation of the cell cycle.

A sort of radiant energy that is visible and moves in waves is light. It is the only type of energy that the human eye is capable of seeing, hence option D is correct.

Radiant energy sources comprise the full electromagnetic radiation spectrum, including gamma rays, x-rays, radio frequencies, microwaves, light, and heat radiated by a bonfire.

Light energy is produced by the Sun and other stars, light bulbs, lasers, and heated things, heat coming off of a heated sidewalk. Radiant energy may be found in X-rays.

Any energy produced by the sun is referred to as solar energy, nuclear fusion occurs in the sun and produces solar energy.

Therefore, In the sun's core, fusion takes place when the protons of hydrogen atoms forcefully collide and fuse to form helium atoms, hence option D is correct.

Explanation:

Abiotic factors are nonliving components.

Answer:

Since each island is very different, birds from each of these islands all have different beaks, colorations, and sizes depending on the natural environmental factors surrounding their island.

Explanation:

I would also add in how birds had to adapt with different beak lengths and sizes in order to be able to get the food type that was most abundant. Natural selection was abundant in this case if one food source (say small seeds) was scarce, a bird with a small beak 1. Had very little if no small seeds to eat and 2. If there were large nuts that required breaking open (ability with birds for larger beaks to do so), the small bird could not break them open and then would unfortunately probably starve to death. Thus, natural selection occured so the birds with the large beaks were able to carry on their traits while the birds with the small beaks did not have as great of an opportunity (if not opportunity) to carry on their traits.
