Answer:
A dominant allele produces a dominant phenotype in individuals who have one copy of the allele, which can come from just one parent. For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent.
Explanation:
A dominant allele becomes a trait even if just one copy of it is present. A recessive allele does not become a trait unless both copies of the gene, one from mom and one from dad, are present. If one dominant allele and one recessive allele are present, the dominant allele trait will be expressed.
Only individuals with an aa genotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait.
Answer:
The concentration of H⁺ in stomach acid is approximately ten times greater than that of lemon juice.
Explanation:
The H⁺ concentration of a solution is exponentially related to its pH value:
![\rm [H^{+}] = 10^{-pH}](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-pH%7D)
.
For lemon juice:
![\rm [H^{+}] = 10^{-2.0} = 0.01\; M](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-2.0%7D%20%3D%200.01%5C%3B%20M)
.
For stomach acid:
![\rm [H^{+}] = 10^{-1.0} = 0.1\; M](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%7B%2B%7D%5D%20%3D%2010%5E%7B-1.0%7D%20%3D%200.1%5C%3B%20M)
.
Thus, the concentration of H⁺ in stomach acid is approximately ten times greater than that of lemon juice.
Answer:
44.95408163 kg
44.95 kg (2 decimal places)
Explanation:
Weight=Mass*Gravity
440.55=m*9.8
Make m the subject
M=440.55/9.8
M= 44.95 kg
False it's composed of 3 phosphate groups not phenol
Electrolysis is a process, which allows us to break down a chemical compound into its elements, completing the balance by adjusting the number of atoms on both sides of the reaction is important because the number of electrons given up during oxidation must be the same as the number of electrons gained during the reduction.
<h3>What is electrolysis of water?</h3>
It is a process of oxidation and reduction of one or more elements that, through the induction of electric current, breaks down the water molecule (H2O), thus producing gaseous hydrogen and oxygen.
Oxidation and reduction processes occur simultaneously and never in isolation, which is why they are called redox reactions.
Therefore, we can conclude that electrolysis is a process where electrical energy will change to chemical energy where it is important that the number of electrons given up during oxidation is the same as the number of electrons gained during reduction.
