Sickle cell anemia is a condition where the red blood cells are deformed. Which is affected by sickle cell anemia?

Answers

Ans.

Sickle cell anemia is defined as a genetically inherited disorder that causes deformation of red blood cells (RBCs) and inadequate oxygen transport. It is caused by a mutation in the gene that encodes for hemoglobin and leads to formation of a defective protein.

The RBCs transport oxygen to the various parts of body with the help of hemoglobin molecules. Due to defective hemoglobin, blood cells become sticky and rigid, and shape like sickles. The resulting sickle-shaped cells get stuck in blood capillaries that block or slow down blood flow or oxygen transport to the body organs.

Thus, 'sickle cell anemia affects oxygen transport in the body.'

A genetic disorder in which the deformation of red blood cells occurs due to which transportation of oxygen is hindered is called sickle cell anemia.

Further Explanation:

The inherited form of anemia is sickle cell anemia. It is a condition during which the body contains an inadequate amount of red blood cells to fulfill the required supply of oxygen in the body. The normal red blood cells are round and flexible and move with ease through the blood vessels. The defective red blood cells during sickle cell anemia appear like a crescent moon and become sticky and rigid. These defective cells cannot pass the blood vessels and get stuck in between. It may lead to a stoppage and slow down of blood flow, which in turn also obstructs the passage of oxygen throughout the body.

The gene mutation is the cause of the anemia. This gene is responsible for the production of haemoglobin. Haemoglobin is an iron-rich compound which provides the blood with its red color. The red blood cells carry oxygen with the help of hemoglobin, which binds oxygen. Abnormal hemoglobin is produced during sickle cell anemia, which makes the red blood cells rigid and sticky.

These defective genes are passed from parents to the offspring and generate an inheritance pattern, which is called autosomal recessive inheritance. This means both the parents must transfer the defective allele to produce an affected child. If a person inherits a sickle cell gene from only one parent, he/she is a carrier of the disease. This implies that the person can further pass on the gene to his/her progeny.

Glucose provides energy for cells. Different cells have different mechanisms for glucose intake. Intestinal cells contain proteins that transport glucose against its concentration gradient. These proteins couple the movement of glucose to the movement of sodium down its concentration gradient. Red blood cells have transporter proteins embedded in their membranes. When bound by a glucose molecule, these proteins change shape and allow glucose to move down its concentration gradient into the cell. Based on this information, what type of transport is used for glucose in blood and intestinal cells?

Answers

The answer is; active transport in small intestines and passive transport in blood cells

In passive transport, no energy is required to transport the glucose molecules because they spon6tanosuely move down their concenntrati0n gradient. The transport protein in the blood cell membrane only enables the molecule to pass across the hydrophobic layer of lipid in the membrane and into the cell.

In active transport, energy is required in the transportation of glucose against their concentration gradient (glucose is highly concentrated in the lumen of the intestines than in the bloodstream). Sodium/Potassium (Na+/K+) pumps play a significant role in the transport of glucose. When sodium diffuses back into the cells, they drag along glucose molecules with them across the sodium-glucose transporter protein.

Answer: active transport in small intestines and passive transport in blood cells

Explanation: It is a Passive Form Of Transport In Blood

This cross will yield four phenotypes in the 1:1:1:1 ratio:rryy x rryy
RrYy x rryy
RrYy x RrYy
RRYY x rryy

Answers

The answer would be:

RrYy x rryy

Here's more about your question:

The Punnet square for this cross is attached below.

As you can see the results will be:

RrYy = 4/16 = 1/4

rrYy = 4/16 = 1/4

Rryy = 4/16 = 1/4

rryy = 4/16 = 1/4

All four phenotypes have a 1/4 chance of occurring. So the ration between them would be 1:1:1:1

RrYy x rryy will yield the phenotypic ratio you want, I think

Which sentence lists events in the cell cycle in correct order, from earlier to later?The chromosomes become longer and thinner; spindle fibers attach to the centromeres.
The nuclear membrane reforms; the chromosomes align in the middle of the cell.
The chromosomes replicate; the nuclear membrane dissolves.
The sister chromatids are separated; the chromosomes condense.
Which of the choices below describe one similarity between meiosis II and mitosis?
In both processes, sister chromatids are pulled apart.
Homologous chromosomes separate in both stages.

Answers

The chromosomes become longer and thinner; spindle fibers attach to the centromeres.

Cell cycle refers to the process by which the cells undergo several DNA duplication activities creating daughter cells. It is very important because without the cell cycle there would be no reproduction of the body cells and that would lead to dysfunctional body organs.
