Answer:
In a neutral atom the number of protons = the number of electrons. 35 protons = 35 electrons. But Bromine anion with a charge of -1 has one extra electron so 35 +1 = 36 electrons. 36 electrons is the number of electrons in the stable inert gas Krypton. ... Protons + neutrons = Mass putting in known values.
Explanation:
The Atomic weight is <span>22.989769 ± 0.00000002 u</span>
That would be C. yy
This is also known as the law of segregation of alleles(Mendel’s law of segregation). So Y and y are separated from each other in meiosis(specifically anaphase 2).
The possible gametes are RY, ry, Ry, rY
B
Publish his findings in a research journal because he is experimenting what medicinal properties can be tested or are associated with the plant. He should have kept the notes in a research journal for making observations so B.
Answer:
Has three dominant alleles
Explanation:
Skin colour is a polygenetic inheritance and it is controlled by three genes pairs of alleles. The human skin is determined by the amount of melanin it contains. A combination of melanin producing alleles determines the skin color.
In the above question, the person has a skin color that is midway meaning only half of the alleles produced melanin. The total number of alleles is 6 and half of it is 3. So, only 3 alleles were dominant and the remaining three were recessive.
