Answer:
Ribosomes
Explanation:
Ribosomes are organelles with the main purpose of protein synthesis in cells, both in eukaryotes and prokaryotes.
Ribosomes create proteins through translation of mRNA, and the linking of amino acids.
These linked amino acids are the proteins, which can also develop into more complex types of protein structures, such as tertiary and quaternary structures.
So, the correct answer is Ribosomes.

How to overcome Confusion?????
Answer:
use a full heal
Explanation:
Female mosquitoes need a meal of blood from a person or other animal in order to produce eggs. It has been discovered that mosquitoes have cells on their antennae that can detect the insect repellent known as DEET. The repellent is not harmful to mosquitoes, but when mosquitoes detect DEET, they will not land on the surface where the DEET has been applied. This protects people from being bitten by mosquitoes. Recently, scientists found some mosquitoes that are resistant to DEET because they do not detect its presence. They bred these mosquitoes and eventually produced a population consisting of about 50% DEET- resistant insects. Identify the process most likely responsible for a mosquito initially becoming resistant to DEET.
Answer:
Mutation followed by natural selection made mosquitos resistant to DEET
Explanation:
Natural selection selects beneficial alleles, which increase their frequency in the population, resulting in adaptation. Aptitude, which is the contribution of each genotype to the next generation, increases too.
In many cases adaptations, resulting from the natural selection process can be correlated to environmental factors or selective pressures applied by other organisms or habitats.
Let us remember that, a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
So, in the exposed mosquitos´ example,
The selective pressure or modeling environmental factor is the DEET repellent.Some of the mosquitos mutated changing their behavior. The new mosquito´s response is not-detection of the repellent presence -only in those individuals carrying the mutations-. Natural selection benefits these mutations. Mosquitos survive and become more resistantProbably some of the mosquitos in the population suffered a mutation that favored them in not detecting repellent DEET. These individuals developed resistance to the chemical and were able to survive and reproduce, enhancing population sizes again. Natural selection benefited the mutation that gave them resistance.
Let us remember that the term resistance refers to an inheritable change in the population sensitivity, reflected through the consecutive failure of the chemical effects, correctly used in order to cause an effect on the insect population.
Repellents might produce a genetic modification in the insects, leading them to not detect the chemical. Insects evolve with the capability of tolerating the DEET dose that normally is used to repel mosquitos
The excessive use of DEET leads to the fixation of new genes -by natural selection- that result from mutations in the mosquito genetic material, which makes them become even more resistant to the chemical.

The pancreas contains exocrine cells that secrete digestive enzymes into the ____________ , and clusters of endocrine cells called pancreatic islets, which secrete insulin and ____________ , to regulate blood glucose levels. When blood glucose levels are high, the pancreas secretes the hormone insulin, which causes the liver to remove excess glucose from the blood and to store it in the liver as ____________ . When this stored form of glucose is low, the liver converts ____________ from fats and amino acids to glucose molecules. Most pancreatic cells produce pancreatic juice, which contains ____________ , to help neutralize the stomach acid. Pancreatic amylase digests ____________ , trypsin digests protein, and lipase digests fat. The major functions of the liver include: removing or detoxifying harmful substances from the blood; storing glycogen, ____________ , and several vitamins; synthesizing many proteins found in the blood ____________ ; and regulating blood cholesterol. Another function of the liver is to produce bile, which is a yellowish-green color because it contains bilirubin, a breakdown product of ____________ . Bile also contains bile salts, which serve to emulsify ____________ in the small intestine.
Answer:
The correct answer is - small intestine; glucagon, glycogen; glycerol, sodium bicarbonate; starch, iron, plasma, hemoglobin; fats.
Explanation:
The digestive enzymes are released in the small intestine by pancreatic cell, the cluster of these pancreatic exocrine cells called pancreatic islets that release insulin and glucagon hormones for controlling blood sugar level.
Insulin stores the excess amount of blood glucose in the liver as glycogen and in the case of low sugar glycerol is converted to glucose from fats. Pancreatic juice contains sodium bicarbonate to regulate acidity and the amylase enzyme helps in digesting starch. The liver stores various nutritional substances such as vitamins and iron and others and release them in blood plasma.

Answer:
Converting information in a mRNA sequence into the amino acid sequence of a protein
Explanation:
The correct answer would be Converting information in a mRNA sequence into the amino acid sequence of a protein.
The inheritance of a gene requires that the DNA sequence of such gene is first transcribed to mRNA in a process known as transcription and then translated to protein in a process known as translation.
During the translation process, the genetic codes in the nucleotide sequence of the mRNA are converted to their respective amino acids joined together by peptide bonds to form a protein.
Hence, the correct answer is that translation is a process that involves the conversion of information in a mRNA into the amino acid sequence of a protein.

Cytokinesis (cytoplasmic division) in plant cells Group of answer choices starts when vesicles cluster at the future plane of division. occurs when the plasma membrane is pulled inward by a ring of microtubules. usually precedes nuclear division. involves a cleavage furrow. occurs exactly the same as in animal cell.s
Answer:
when vesicles cluster at the future plane of division
Explanation:
Cytokinesis is the process whereby the cytoplasm of a cell divides into two. This process of cytokinesis occurs after nuclear division i.e. division of the nucleus. However, cytokinesis differs in plant and animal cells.
In plant cells, the separation of the cytoplasm involves the formation of a cell plate. The process begins when a structure called phragmoplasts carry vesicles to the cell plate. In other words, vesicles cluster at the future plane of division (cell plate).

what are the three main particles of soil are? How do these shape and influence the type of soil we observe and its uses?
Answer:
Soil particles vary greatly in size, and soil scientists classify soil particles into sand, silt, and clay. Texture indicates the relative content of particles of various sizes, such as sand, silt and clay in the soil. Texture influences the ease with which soil can be worked, the amount of water and air it holds, and the rate at which water can enter and move through soil. Soil provides plants with foothold for their roots and holds the necessary nutrients for plants to grow; it filters the rainwater and regulates the discharge of excess rainwater, preventing flooding; it is capable of storing large amounts of organic carbon; it buffers against pollutants, thus protecting groundwater.
