Hemoglobin SS and sickle beta zero thalassemia are the most severe forms of sickle-cell disease and are sometimes referred to as sickle cell anemia. Hemoglobin SC disease is considered moderate and in general, sickle beta plus thalassemia is the mildest form of sickle-cell disease.

You can tell if asthma is related to exercise
(i) If a person has a coughing and shortness of breath. This feels a few minutes after an activity
(ii) You feel constricted. When on the exercise you feel like you can’t get enough air in your lungs.
(iii) A person feels fatigue after training instead of being energized.
(iv) If a person lives in a dry environment the breath in air that is divided and colder than the other parts of your body.
Answer: The correct answer is D
Explanation:
As long the progression of the cell to the M phase of the cell cycle is controlled by the chemical signals in the cytoplasm, then a cell in early M phase fused with a cell in G1 would result in the chromatin in prep of nuclear division in both cells to be condensed.
When a cell is immersed in a hypotonic solution, the volume of the cell will rise as it will cause will be a net inflow of water inside the cell. If the concentration of solutes outside the cell is lower as compared to inside the cell and when the solutes are not able to cross the membrane, then the solution is called hypotonic to the given cell.
The ability of an extracellular solution to induce water to osmotically enter or depart a cell is known as tonicity.
Three terms—hypertonic, hypotonic, and isotonic—are employed in order to evaluate if a solution would cause water to move into or out of a cell:
- If a cell is immersed in a hypertonic solution, it will lose volume because there will be a net flow of water out of the cell.
- A cell will shrink if it is submerged in a hypertonic solution because water will escape the cell.
- Since there is no net water movement in an isotonic environment, the cell's size remains constant.
- A cell will absorb water and swell when it is exposed to a hypotonic environment.

The answer to the biology question being presented above would be 'sexual reproduction'. Genetic variability is the most important result of sexual reproduction. In this variability, the genes are varied through sexual union and reproduction.
