The nucleus and the ribosome are the two cellular structures that will be most involved in making the enzyme in the frog's cells.
What is gene expression?Gene expression is the transcription and translation of a gene (DNA) into messenger RNA and thus into a protein.
Transcription is the synthesis of RNA under the direction of DNA while translation is the process whereby a strand of mRNA directs assembly of amino acids into proteins within a ribosome.
Transcription occurs in the nucleus of the cell while translation occurs in the ribosome.
Therefore, the nucleus and the ribosome are the two cellular structures that will be most involved in making the enzyme in the frog's cells.

DNA replication results in two identical daughter molecules each consisting of one old (original) strand and one newly-synthesized strand. Therefore, it is true.
What is DNA replication?The process of duplicating the parent DNA helix into two identical daughter helices is known as DNA replication. One parent strand is passed down to each daughter strand in this semi-conservative procedure.
In prokaryotic cells, DNA replication takes place in the nucleoid area, whereas it happens in the nucleus in eukaryotic cells. Prior to cell division, DNA replication takes place in the S phase of the cell cycle.
Replication fork pairs that form at the origins of replication and then move in opposition to one another carryout genome duplication. When convergent replication forks meet, DNA replication is complete. Hence, it is true.

Many of the sun's rays may be PARTIALLY blocked by dust or clouds
formed by volcanic eruptions or pollution. What are some possible short-
term effects of this on photosynthesis?
Photosynthesis will happen faster/more
Phstosynthesis will happen slower/less
Photosynthesis will NOT happen at all
Nothing will change
Answer:
B. Photosynthesis will happen slower/less
Explanation:
Option B is the possible short-term effect on photosynthesis when the sun's rays are partially blocked.
Photosynthesis is the process whereby plants manufacture their own food with the use of sunlight and carbon dioxide. When this occurs, (energy in form of glucose) and oxygen are produced. The oxygen is released for animals to use.
Photosynthesis makes use of sunlight. But if sunlight is partially blocked, the process by which photosynthesis occurs becomes slow or less. This is because as the sunlight is partially blocked, there is no adequate supply of sunlight to carry out photosynthesis.

Answer:
The heart consists of four chambers organized into two pumps (right and left) for the purpose of providing blood flow to the systemic and pulmonary circulations. The right atrium receives deoxygenated blood from the entire body except for the lungs via the superior and inferior vena cavae!
The heart has four chambers: two atria and two ventricles.
The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
The right ventricle pumps the oxygen-poor blood to the lungs.
The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
The left ventricle pumps the oxygen-rich blood to the body.

How do guard cells maintain homeostasis?
Answer:
Explanation: Guard cells in the plants prevent water loss from it in cases of soil dryness or high temperature by closing themselves. If this does not happen, water will keep leaving the plant by the process of transpiration in these harsh conditions and the plant will not have the important medium for the homeostasis process to continue.

What is mRNA?Messenger ribonucleic acid is a single-stranded RNA molecule that equates to a gene's nucleotide makeup and is read by a ribosome during the protein polymerization reaction.
The function of mRNA is to transport protein details from the nucleus of a cell to the cytoplasm.
Here the protein-making equipment likes to read the mRNA sequence as well as translates each three-base codon into the corresponding amino acid in a burgeoning protein chain.
Messenger RNAs are single-stranded molecules that move genetic information from the nucleus to the cytoplasm, in which proteins are sequenced.
Thus, the correct option is J.

If hydrogen peroxide is stored in a clear glass bottle and is left to stand, it decomposes into water and oxygen.Which of the following correctly shows the balanced equation for this decomposition?
1. 2HO2-------------> 2HO + O
2. 2H2O2--------------> 2H2O + O2
3. 2H2O-----------------> 2H2O + O2
4. H2O2----------------> H2O + O
Help pls
Answer:
2. 2H2O2 -> 2H2O+ O2
Explanation:
This equation is balanced because there are equal amounts of each element on each side. 4 Hydrogen on the left, 4 On the Right. 4 Oxygen on the Left, 4 on the right.
Although 1 is balanced it is not the Chemical equation for hydrogen peroxide (H2O2)
2. is not the equation for Hydrogen Peroxide

Why is the decomposing web important
Why is photosynthesis so important to living organisms?
Most consumers can convert energy into food, but they can’t make enough of it, so they need producers, too.
Consumers do not usually live in areas where they can get energy, so they have to eat producers to get enough energy.
All living organisms need energy to stay alive, but only producers can directly convert energy into food.
Decomposers take so long to recycle dead and decaying matter that producers have to make up the difference.
Answer:
All living organisms need energy to stay alive, but only producers can directly convert energy into food.
Explanation:
The process of photosynthesis is very important because all living organisms need energy to stay alive, but only producers can directly convert energy into food.
Photosynthesis is the process whereby green plants manufacture their food in the presence of carbon dioxide and water.
They take light energy from the sun and produce food materials. The light energy is converted to chemical energy which are stored in carbon chains as glucose. The chemical energy is then used by other living organisms for their own nourishment.
