Answer:
B. 26amu
Explanation:
The nucleus of an atom in an element contains protons, electrons and neutrons. The proton number equals the electron number in a neutral atom. The proton number is also called the atomic number, denoted by Z.
The mass number also called Atomic mass unit (amu) in this case, of an element is the sum of the proton number and the neutron number in the atom of that element. The mass number is denoted by A.
Hence, A = Z + N
Where A = Mass number
Z = Proton (atomic number)
N = Neutron number
In this question, N is 11 while Z is 15
Hence, the mass number of the element in the question, in AMU, is 15 + 11 = 26amu.
Explanation:
Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein.
An allele is dominant and heterzygote (Pp) when a dominant allele (P) is crossed with a recessive allele (p).
Explanation:
A dominant allele is the one with a particular dominant character or phenotype which dominates even though there are other alleles found.
A heterozygous allele results from two different alleles coding for a gene.
A heterozygous dominant allele (Pp) results from the crossing of a dominant allele (P) with a recessive allele due to complete masking of the recessive allele (p).
For example, when dominant brown eyes are crossed with recessive blue eyes, in a heterozygous dominant allele results in brown eyes and masks the recessive blue eyes.
