Answer:
C
Explanation:
Protein synthesis occurs through a chain of processes.
1) transcription of DNA in nucleus to form a RNA strand
2) RNA then undergoes modifications to form a mRNA
3) mRNA then migrates out of nuclear pore and complexes with a small and large ribosomal subunit to form a translational complex
4) translation occurs at the ribosomes to form a polypeptide by joining correct amino acids together through the formation of peptide bonds
5) polypeptide gets modified chemically and folded physically to form a protein in rough endoplasmic recticulum and golgi body.
Protein synthesis is accomplished primarily by the interaction two cell structures namely; nuclei and ribosomes.
PROTEIN SYNTHESIS:
Protein synthesis is the series of process that involves how proteins are produced by genes. Protein synthesis takes place in two stages namely: transcription and translation.TRANSCRIPTION:
Genes are stored in the nucleus as DNA, hence, the process of synthesizing mRNA from DNA called transcription, takes place in the nucleus.TRANSLATION:
Translation is the process whereby mRNA is used to synthesize proteins in the ribosome. The mRNA, produced in the nucleus of a cell moves to the ribosome, which is the site of protein production. Therefore, protein synthesis is accomplished primarily by the interaction two cell structures namely; nuclei and ribosomes.Learn more at: https://brainly.com/question/241631?referrer=searchResults

Choose the correct word that describes the description. When there is very little solute dissolved in a lot of solvent. solute? solvent? saturated? dilute?
Answer: Dilute
The maximum amount of solute that can be dissolved in a solvent is a saturated solution at a certain temperature is called saturated solution.
Solute and solvent are not the correct description.
A dilute solution has very little solute dissolved in the solvent.

Which describes a target cell? releases hormones into the blood produces a particular hormone recognizes a hormone’s chemical structure destroys hormones in the blood
Answer:
recognizes a hormone’s chemical structure
Explanation:
In living systems, chemical messengers called hormones are secreted into the body via the bloodstream or ducts by certain glands called endocrine glands e.g pancreas, hypothalamus etc. These hormones are meant to effect a physiological change in certain cells called TARGET CELLS.
In biology, a target cell is any receiving cell that has the ability to respond to signals and messengers like hormones. This responding ability of hormones is due to the possession of specific receptor sites for the specific hormones. The receptor on a particular target cell recognizes that specific hormone's chemical structure, hence, will only respond to it.
For example, an insulin hormone secreted by the pancreas will only be responded to by a target cell that recognizes the chemical structure of the insulin protein using its receptor molecule.

On April 20, 2010, an explosion on the Deepwater Horizon Macondo oil well drilling platform released 4 million barrels (636,000 cubic meters) of oil into the Gulf of Mexico. It took scientists and engineers nearly three months and several different attempts to cap the well. The Macondo oil well was located 1524 m (5000 feet) below the surface of the water, about 80 km (50 miles) off the coast of Louisiana. The spill affected 2113 km (1300 miles) of shoreline along the coasts of five states. Most crude oil contains 84–87% carbon by weight. Scientists have not yet fully assessed the environmental impact of the accident.
Computer modeling can be used to help improve cleanup and response systems for the next major oil spill. Which of these uses demonstrates how computer modeling can be used to minimize the impact of another spill?
a
Creating a model of how the oil spread through the Gulf of Mexico to predict what areas need the greatest amount of protection.
b
Calculating the total oil that entered the Gulf of Mexico during the spill.
c
Recording the number and type of each dead organism collected during the spill.
d
Finding the average flow rate of the oil through the burst pipeline during the spill.
Answer:
I would pick a, because if you can see where the most oil spills or where it flows it will be easier to predict when another spill is about to happen.

Why is flooding more likely after many trees are removed from an area?
A. Without the trees, evaporation rates slow down.
B. Without the trees, water runs off rather than percolating into the
soil.
C. Without the trees, most of the animals die and therefore don't
drink the water.
D. Without the trees, precipitation increases dramatically.
SUBMIT
Answer:
Without the trees, water runs off rather than percolating into the
soil.
Explanation:
Flooding is the excessive flow of water due to increased rainfall. It usually deprives the soil of the affected area of essential nutrients. However, the presence of trees in an area can help prevent or reduce the possibility of flooding. The roots of large trees help hold the soil together, which improves the porousness of the soil. Also, trees store water that is meant to runoff.
Without the trees, the absorption or percolation of water into the ground/soil will be reduced, hence, the excess water runsoff the surface leading to flooding.
