Answer:

B. half, half

Explanation:

When a diploid organism has one dominant allele and one recessive allele of a gene, it is said to be heterozygous for the gene. During gamete formation, random segregation of homologous chromosomes leads to separation and random distribution of alleles of a gene in separate gametes. Therefore, a heterozygous individual for a gene forms two types of gametes: 50% of the gametes with dominant allele and rest 50% with the recessive allele.

For instance, an individual with an "Aa" genotype will form 50% gametes with an "A" allele and 50% gametes with an "a" allele.

<h3><u>Answer;</u></h3>

All of the above are True

  • Part of the Bohr model proposed that electrons in the hydrogen atom are located in "stationary states" or particular orbits around the nucleus.
  • An orbital is the volume in which we are most likely to find an electron.
  • The uncertainty principle states that we can never know both the exact location and speed of an electron.
  • The emission spectrum of a particular element is always the same and can be used to identify the element.
