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.

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.

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.

after death, the cornea absorbs fluid and becomes opaque. in a living person, the cornea is translucent due to _______________.
Answers
Given what we know about human anatomy, we can confirm that the cornea of a live human is translucent due to the arrangement of its collagen fibers and the lack of vascularity.
One important factor in the translucent nature of the cornea and lens is its lack of vascularity. This area of the eye has few if any vascular components, which contributes to its lack of pigment.
However, the main component that contributes to the translucent nature of the human cornea is its very specific arrangement of collagen fibers.
The bundled nature of these fibers, together with the water content of the cornea, allow it to remain translucent.
