The sickle cell anaemia is a condition, in which the red blood cells of the affected person becomes sickle shaped. This condition is caused by an autosomal recessive condition, which is a genetic disorder. Due to the sickle shaped RBC, the Hemoglobin becomes unable to bind with the oxygen efficiently, as a result it causes anaemia.
As this condition is caused by genetic abnormality, it can be detected by a DNA analysis.
Population growth is the increase in the population number of a given species in a time. Longevity, migration and fertility rates affect population growth.
<h3>What are the factors affecting population growth?</h3>
<u>Increased Longevity</u> has impacted the population growth as the life expectancy has resulted in the accumulation of more people as their age of living has increased.
<u>International Migration</u> can affect the population growth positively and negatively as moving of the person from one region will decrease its population growth while the region where they go will have increased population.
<u>Fertility Rates</u> has a great impact on the population as the fertility rate had decreased due to many factors and the population has declined.
Therefore, option A. longevity option B. migration and option C. fertility rates influence the population growth.

Answer: It is the carbon dioxide assimilation or carbon fixation reactions or the Calvin cycle.
Explanation: Carbon dioxide assimilation reactions are light independent reactions of photosynthesis. They do not require light to occur, thus they occur in the dark. The carbon dioxide assimilation reactions are driven by ATP and NADPH that are produced in the light dependent reactions of photosynthesis. The carbon dioxide assimilation reactions are the second stage of photosynthesis. It involves the incorporation of three molecules of carbon dioxide into three molecules of ribulose 1,5-bisphosphate in a cyclic pathway known as the Calvin cycle. In these reactions, triose phosphates are produced which serve as precursors for synthesis of glucose and other related substances such as starch.
