Answer:

Bacteria

Explanation:

Bacteria are a group of single celled organisms that are neither plants or animals.

Bacteria lack cell organelles such as the nucleus and the chlorophyll.

They can be found in many environments and most of them are adapted to survive in extreme environments such as hot-springs where the temperatures are extremely high.

Unlike the plant cell wall, bacterial cell wall has a layer of peptidoglucan which determines their shape. Their cytoplasm contains both DNA and RNA.

.. Which of the following mutations would have the potential to affect future generations of
ch4aika [34]

Answer choices:

  • A frame shift mutation in the X chromosome of a cheek cell
  • A chromosomal mutation in the Y chromosome of a kidney cell
  • 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.
