Which of the following correctly describes the functions of the rough endoplasmic reticulum (RER) and Golgi apparatus, respectively?
Answer:
D
Explanation:
The rough endoplasmic reticulum produces proteins and the Golgi apparatus packages and transports the proteins.
The functions of the rough endoplasmic reticulum (RER) and Golgi apparatus is to process the protein, synthesis of protein for cell secretion. Thus option D is correct.
what is the function of Golgi apparatus ?The Golgi apparatus is present in eukaryotic cells have the structure of stacks of membranous sacs; The Golgi apparatus modifies, sort and transport the proteins for the secretion.
These are membrane-bound organelle present in the cytosol of eukaryotic cell.
It involves modification of the proteins, sorting and packaging them, and it mainly comes from the endoplasmic reticulum. The folds like cisternae of the Golgi involved in the transport of molecules and producing lysosomes.
It packages the proteins into membrane-bound vesicles transported to various organelles like lysosomes, plasma membrane or secretion; it also take part in the transport of lipids and the formation of lysosomes, it also serves as the site of synthesis of various glycolipids, sphingomyelin, etc.
Thus option D is correct.

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.

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.

The Canada lynx is a rare wildcat in Minnesota. The lynx has large "snowshoe' like feet that enables it to walk on top of deep, soft,
snows. Snowshoe hares are also common in the area. According to the graph of the interactions between the lynx and the hare, what
best describes their ecological relationship?
A)
Mutualism
B)
Predator/prey
C)Parasite/Host
D)
Interspecific competition
Answer: B) Predator/prey
=========================================================
Explanation:
The lynx is the predator that hunts and eats the snowshoe hare, which is the prey.
The graph shows that when the hare population is large, so is the predator population because they rely on the hares as a source of food. However, the more predators there are, the less prey there will be. This causes the prey population to decrease. In turn, this decrease causes the predator population to decrease as well. If there's less food, then some of the lynx population will starve to death.
At some point, the hare population will rebound and go back up due to less predators eating them. They have a better chance to survive. As the hare population goes up, so does the lynx population. They're both strongly linked together, and we have this cyclic pattern the graph indicates. You could say this is "the cycle of life" or "cycle of nature" so to speak.
This is a very simplistic viewpoint because it does not account for other factors such as other predators and other prey, and it also doesn't take account of things like habitat loss for instance. Despite that, such predator-prey models are still useful to understand the connection between the two species.

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.

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.
