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.
It is approximately 0. It could be barley higher or lower for both. You have to take the altitude into consideration.
Answer:
CH4 +O2 => CO2 + 2 H2O
None were in excess
Explanation:
Equation for the reaction is,
CH4 + O2 =>CO2 +2 H2O
No of moles of CH4 = (20 /1000)/24 =0.02 /24 = 0.00083
No of moles of O2 =20 /24000 = 0.0083
CH4 : O2 = 1:1
THEREFORE
None of the gases were in excess.
Hello!
First you need to calculate q
<span>delta U is change in internal energy </span>
<span>delta U = q + w </span>
<span>q is heat and w work done </span>
<span>here work was done by the system means energy leaving the system so w is negative </span>
<span>delta U = q + w </span>
<span>q = delta U - w = 6865 J - (-346 J) = 7211 J = 7.211 KJ </span>
<span>q = m x c x delta T </span>
<span>7211 J = 80.0 g x c x (225-25) °C </span>
<span>c = 0.451 J /g °C
</span>
Hope this Helps! Have A Wonderful Day! :)
