<span>The answer is letter C.

Protonema or Protonemata in plural form, refers to the thread-like chains of cells that form during the haploid phase of a bryophyte cycle. They give rise to gametophytes much like in the growth of moss which originates from spores that eventually develop into a leafy gametophore. Simply put, a protonema is a juvenile gametophyte that grows through an apical cell division. This then eventually grows into its adult form developing stems and leaf like structures that are photosynthetic.<span>

  • A point mutation in the first chromosome of a sperm cell
  • A substitution mutation in the third chromosome of a uterus cell

Answers:

A point mutation in the first chromosome of a sperm cell

Explanation:

Only mutations that affect the germ line are passed on to the next generation. Therefore, only mutations in the egg and sperm of an individual have the potential to affect the next generation.

Mutations in cheek cells, kidney cells, and uterus cells might cause cell death or cancer. This genetic material is not passed on to the next generation, only the egg and sperm contribute this material. Therefore, only mutations here will affect the generation.
