Answer:
The sickle cell gene is recessive to the normal gene
Please find the description below
Explanation:
Sickle cell is a blood disease inherited genetically from one's parents. The sickle cell is associated with the blood genotype of an individual. The allele for sickle cell trait is S, while that of the normal gene is A. In this gene, the allele for normal gene (A) is dominant over the allele for sickle cell (S).
Hence, people that have one sickle cell gene (S) and one normal gene (A) will have an AS genotype. The individual will have few defective cells and no symptoms because the phenotypic expression of the sickle cell allele has been masked by the normal one.
Answer:
3.4 × 10²³ molecules of CBr₄
Explanation:
Given data:
Mass of CBr₄ = 189 g
Number of molecules = ?
Solution:
First of all we will calculate the number of moles.
Number of moles = mass / molar mass
Number of moles = 189 g/ 331.63 g/mol
Number of moles = 0.6 mol
Now the given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
Foe 0.6 moles of CBr₄:
0.6 mol × 6.022 × 10²³ molecules of CBr₄ / 1 mol
3.4 × 10²³ molecules of CBr₄
The answer to the question is
35,400,000 cm^3
Dont quote me here, I would do some more research. but I think its oblique lighting. I'm trying to remember but im not fully sure :) sorry if im wrong
