Explain how the structure of DNA determines the structure of proteins which carry
out most of the work of cells.
Explanation:
A; Structure and Function. All cells contain genetic information in the form of DNA molecules. Genes are regeions in the DNA that contain the instructions that code for the formation of proteins, which carry out most of the work of cells.
The linear order of nucleotides in a gene sequence is used to encode a specific protein by the sequential processes of transcription and translation.
Deoxyribonucleic acid (DNA) is a double helix molecule that contains the information required to synthesize all proteins present in an organism.
During the mechanism of gene transcription, a specific fragment of DNA referred to as a 'gene' is used as template to encode a complementary messenger RNA (mRNA) sequence.
Subsequently, this mRNA travels to the ribosome where it is used as a template to encode a specific protein.
The linear order of triplets of nucleotides or 'codons' in the mRNA sequence specifies the linear order of amino acids in the nascent polypeptide chain (i.e., the protein).
In conclusion, the linear order of nucleotides in a gene sequence is used to encode a specific protein by the sequential processes of transcription and translation.

What biotic and abiotic factors influence the flow of matter and energy in different biomes
Answer:
Temperature, water and nutrients.
Explanation:
Biotic factor refer to the living component of the ecosystem. Plants and animals.
Abiotic factor refer to the nonliving component of the ecosystem such as light, temperature e.t.c.
Biomes refers to group of terrestrial ecosystems on the earth.
Therefore, the following factors affect biomes
Water: water can affect biomes in the sense that too much of it can lead to flood, thereby leading to loss of plants and animals. Decrease of it can lead to famine which also can lead to loss of biomes.
Temperature: The best temperature should be optimum temperature. An increase or decrease in temperature have negative effect on biomes which can lead to low vegetation, dehydration, inactiveness of animals.
Nutrients: nutrients availability can lead to increase in plants growth. Vegetation will increase if there is adequate nutrients supply but if there is low nutrients there will be reduced growth.
Therefore, temperature, nutrients and water is important for biomes.

What best describes the role of photosynthesis and respiration in the carbon cycle?
Answer:
Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
Explanation:
Please mark me as brainlist
Photosynthesis removes carbon from the atmosphere, respiration adds carbon to the atmosphere.
What is photosynthesis?Photosynthesis is defined as the process through which plants convert carbon dioxide, water, and sunshine into oxygen and sugar for energy.
It can also be defined as a method used by plants and other living things to change light energy into chemical energy that can then be released through cellular respiration to power the organism's activities.
Through photosynthesis, plants transport carbon from the atmosphere into the biosphere and up the food chain. They use solar energy to chemically combine carbon dioxide, oxygen, and hydrogen from water to create sugar molecules.
Photosynthesis is primarily used to convert solar energy into chemical energy, which is then stored for use at a later time.
Thus, photosynthesis removes carbon from the atmosphere, respiration adds carbon to the atmosphere.

Paleontologists construct a model of a dinosaur from its fossil bones and teeth. The fossil bones and teeth can help the paleontologists to infer all of the following about the dinosaur except the?
height of the dinosaur,
type of food the dinosaur ate
length of the dinosaur,
skin color of the dinosaur
Answer:
B - Dinosaur Skin
Explanation:
Unless the skin is mummified, like that of a Pinacosaurus, the chromatin in the bones will be completely deteriorated.
From fossils, scientists can learn more about dinosaurs. Scientists can learn about dinosaur lengths and tooth shapes from fossils. Scientists speculate on the weights, movements, and diet of the dinosaurs.
What are fossils?Fossils are defined as the well-preserved remnants of plants and animals whose carcasses were buried beneath ancient seas, lakes, and rivers in sediments like sand and muck. Usually, sedimentary rocks include fossils, though rarely, low-grade, fine-grained metamorphic rocks will as well. It's possible that the fossils have been removed, leaving molds in the surrounding rock.
Take note of pattern, color, and shape. Matthew continues, "Seek for something distinctive on the ground, and as you examine it, look for patterns." Dinosaur bones typically have a lined organic pattern, which are the original bone tissue's preserved Haversian canals.
Thus, from fossils, scientists can learn more about dinosaurs. Scientists can learn about dinosaur lengths and tooth shapes from fossils. Scientists speculate on the weights, movements, and diet of the dinosaurs.

What happens to DNA once transcription is done?
O It is destroyed.
O It makes more copies of itself right away.
O It zips back up until it is necessary to transcribe the gene again.
O It mutates.
Answer:
it makes more copies of itself right away
Explanation:
transcription is the process by which the information in a strand of DNA is COPIED into a new molecule of the messager RNA
When DNA transcription is done, it zips back up until it is necessary to transcribe the gene again (option C)
What is DNA transcription?The process of DNA transcription involves copying the information, from DNA into RNA.
Once transcription is complete the DNA molecule returns, to its double helix structure. This occurs because DNA is highly stable and doesn't require transcription. The DNA molecule is transcribed again solely when the cell requires production of a protein.
With the above information, we can conclude that when DNA transcription is done, it zips back up until it is necessary to transcribe the gene again (option C)

What is meant by "concentration"? How can you increase the concentration of salt (electrolytes) in a solution of water? How can you decrease the concentration of electrolytes in a solution?
Answer:
See the answer below
Explanation:
The concentration of a solution refers to the amount of solute that is dissolved in a particular amount of solvent.
In order to increase the concentration of salt in a solution of water, more solute (that is, the salt) would be required to be added to a fixed volume of the solution. The more the amount of the salt added, the more the concentration of the solution provided the volume remains constant.
In order to decrease the concentration of electrolytes in a solution, more solvent would be required to be added to the electrolyte while keeping the dissolved solute constant. The more the added solvent, the lower the concentration as long as the amount of solute dissolved remains constant.

A model answer for translation is always this:
mRNA leaves the nucleus via the nuclear pores and travels to a ribosome (in the cytoplasm or on the rough endoplasmic reticulum)
The ribosome attaches to the start codon on the mRNA.
A tRNA molecule with an anticodon complementary to the start codon on the mRNA carries a specific amino acid to the ribosome and lines up against the mRNA codon.
This is repeated, and each tRNA molecule transports a unique amino acid to the ribosome until the stop codon on the mRNA strand is reached.
As the ribosome moves along the mRNA strand, peptide bonds form between the adjacent amino acids, forming a polypeptide chain.
This chain detaches from the ribosome and will undergo folding to become a specific type of protein.
