*Sickle cell disease is a constitutional corpuscular hemolytic anemia related to an abnormal structure of the globin chain. It is an autosomal recessive disease, which means homozygosity is necessary to fully express the illness.
*It corresponds to the synthesis of an abnormal hemoglobin, HbS, which is different from normal Hb (HbA).
*The S allele (located in the chromosome 11), responsible for the anomaly, is especially widespread in the African continent, it is also found in other regions of the Mediterranean.

*Mutation GAG to GTG leading to the substitution Glutamine by a valine in position 6 of the chain of the globine.</span>
They live about 2 weeks to 3 weeks I think and they probably would die in 4 days.
Answer:
When the plant cell is placed in a hypotonic solution , it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting. The plant cell is said to have become "turgid" i.e. swollen and hard. The pressure inside the cell rises until this internal pressure is equal to the pressure outside.
Explanation:
The right answer is A. greater leaf surface area.
In botany and agronomy, the specific leaf area (SFS) is defined as the ratio of the leaf area to the dry weight of the leaf (expressed in m².kg-1).
The specific leaf area reflects the "thickness" of the leaves and has a particular physiological significance. This parameter is correlated positively with the photosynthetic capacity of the plant.
The specific leaf area can be used to estimate the reproductive strategy of a particular plant based on, among other factors, light and moisture levels. The specific leaf area is one of the most widely accepted key features used in the study of leaves.
