Answer:
The correct answer would be - "aa".
Explanation:
Albinism is an autosomal recessive genetic condition which means it will be expressed only if both alleles for the pigmentation are recessive. If a single copy of the dominant allele present with the recessive allele the expression of the recessive allele would be masked by it and skin will be pigmented however they will act as carriers of the condition.
There would be three condition or three allele combination:
AA - no recessive allele so no albinism
Aa - dominant allele with recessive allele which means carrier but pigmented skin
aa - both alleles are recessive so the albinism will be expressed.
Answer:
Fireflies produce a chemical reaction inside their bodies that allows them to light up. This type of light production is called bioluminescence. When oxygen combines with calcium, adenosine triphosphate (ATP) and the chemical luciferin in the presence of luciferase, a bioluminescent enzyme, light is produced.
Answer:
123.2 L
Explanation:
We must first put down the required reaction equation;
6CO2(g) + 6H2O(g) ------> C6H12O6(g) + 6O2(g)
We know that 1 mol of a gas contains 22.4 L
hence the number of moles of carbon dioxide is obtained from;
1 mol = 22.4 L
x mol = 738 L
x = 738/22.4 = 32.9 mols
For water;
1 mol = 22.4 L
x mol = 792 L
x = 792/22.4
x = 35.4 mol
We obtain the limiting reactant;
6 mols of CO2 = 1 mole of glucose
32.9 mols of CO2 = 32.9 * 1/6 = 5.5 moles of glucose
For water;
6 mols of water yields 1 mol of glucose
35.4 mol of water yields 35.4 * 1/6 = 5.9 moles of glucose
CO2 is the limiting reactant
1 mol = 22.4 L
5.5 mol = 5.5 * 22.4 = 123.2 L
