Making energy available for cellular activities

Answers

Answer:

The answer is C Providing information from DNA that is used to form proteins

Explanation:

i took the test

The statement that demonstrates the role that mRNA play in protein synthesis is as follows:

It provides information from DNA that is used to form proteins.

Thus, the correct option for this question is C.

What is Protein synthesis?

Protein synthesis may be defined as a type of biological process through which polypeptide chains are formed from coded combinations of single amino acids inside the cell. The process of protein synthesis terminates with the help of two processes:

Transcription.Translation.

The process of transcription involves the copying of a DNA sequence of a gene in order to make an RNA molecule. This RNA molecule is known as mRNA which determines the linkage of DNA from the manufacturing of the proteins. This process is carried out in the nucleus of the cell.

While the process of translation involves the synthesis of proteins using the genetic information carried in messenger RNA (mRNA). This process is carried out in the cytoplasm of the cell.

Therefore, the correct option for this question is C.

What is a isotonic solution? How does it affect a red blood cell?
What is a hypertonic solution? How does it affect a red blood cell?
What is a hypotonic solution? How does it affect a red blood cell?
Answer plz!

Answers

Answer: If you place an animal or a plant cell in a hypertonic solution, the cell shrinks

Explanation: because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). ... A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.


An isotonic solution is one wherein the solute concentration across the semipermeable membrane is the same resulting in an equilibrium state.

They do not shrink or swell in an isotonic saline solution, i.e., 0.9% w/v solution of sodium chloride

Hypertonic solution: A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood.

Now, let’s suppose RBCs are placed in a solution with a sodium chloride concentration of 2% w/v. The sodium chloride concentration of 2% w/v is greater than the RBC’s sodium content and hence the solution is hypertonic. This will result in shrinkage of the RBCs known as crenation

When a solution has a lower solute concentration than the solution present across the semipermeable membrane, it is known as a hypotonic solution. As a result, when a cell is placed in a hypotonic solution, an osmotic pressure gradient forces the solvent to move into the cell in order to attain equal solute

In another situation, let’s suppose RBCs are placed in a solution with a sodium chloride concentration of 0.1 % w/v. The sodium chloride concentration of 0.1% w/v is less than the RBC’s sodium content and hence hypotonic saline. This will result in swelling and eventually bursting of the RBCs which will result in the release of hemoglobin. This is known as hemolysis which is a very dangerous situation.

3. Sorry do not know the correct answer

Answer:

transcription starts with Initiation/the nucleus/DNA and makes mRNA with the aid of Polymerase RNA enzyme

Explanation:

Transcription is the process in protein synthesis consisting of a starting process of initiation where the nucleus hosts the creation of an mRNA sending the coding message to the ribosome, but the starting process is the Polymerase binding to a site on the DNA strand, then it makes the mRNA through the other steps in transcription.

What is cell cycle?

Cell cycle is defined as cycle in which cell produces, grows and divides. The cell cycle has mainly three steps the first one is G1 phase in which the size of cell increases, S phase synthesis of DNA takes place and the third step is G2 phase in which cell ready to divide.

Cell is defined as the base of life as it is the structural as well as functional unit of life. Cell is made up of pre existing cells and the cell contain various cell organelles such as mitochondria, endoplasmic reticulum, ribosomes, golgi appratus, nucleus, and cytoplasm.

Basically, cell is of two type one in prokaryotic and another one is eukaryotic. The prokaryotic cell is known as pre mature cells as they do not contain cell organelles and eukaryotic cell are known as advanced and developed cells as they contain several cell organelles.

Therefore, Robert Hooke was the first person to observe cells. He observed these cells in a piece of cork. Thus, option A is correct.

damage to the sinoatrial node in humans would ________.

Answers

Answer:

have a decrease in blood pressure

Explanation:

hope it helped<3

mark brainlliest

Damage to the sinoatrial node in humans can result in irregular heartbeats, abnormal heart rhythms, decreased cardiac output, and an increased risk of sudden cardiac arrest. Prompt medical evaluation and appropriate treatment are crucial to manage these effects and maintain a healthy heart rhythm.

Damage to the sinoatrial (SA) node in humans would result in disruptions to the normal electrical conduction system of the heart. The SA node is often referred to as the "natural pacemaker" of the heart because it initiates the electrical impulses that regulate the heartbeat. Here's how damage to the SA node would affect the heart:

1. Irregular Heartbeat: The SA node is responsible for setting the pace of the heartbeat. If it is damaged, the heart may beat too fast, too slow, or irregularly. This can lead to symptoms like palpitations, dizziness, and shortness of breath.

2. Abnormal Heart Rhythms: Without the SA node functioning properly, other areas of the heart may take over the role of generating electrical impulses. However, these impulses may not be coordinated or synchronized, resulting in abnormal heart rhythms such as atrial fibrillation or heart block.

3. Decreased Cardiac Output: The SA node helps regulate the timing of the heart's contractions, ensuring efficient blood flow throughout the body. Damage to the SA node can disrupt this coordination, leading to decreased cardiac output. This means that the heart may not be able to pump enough blood to meet the body's needs, resulting in symptoms like fatigue and weakness.

4. Risk of Sudden Cardiac Arrest: In severe cases, damage to the SA node can increase the risk of sudden cardiac arrest. Without the SA node's ability to regulate the heartbeat, the heart may stop pumping blood effectively, leading to a life-threatening emergency.

5. Treatment Options: Treatment for damage to the SA node depends on the severity and symptoms. In some cases, medication or cardiac devices like pacemakers may be used to regulate the heart's rhythm and ensure proper electrical conduction.
