Answer:

Archaea that live in extremely salty water are called as halophiles. Normal organisms would shrivel in high salt condition because water would be pulled out of them. Halophiles have developed several mechanism to avoid this problem.

  • The first route is by increasing their osmolarity. They accumulate organic compounds called as osmoprotectants in the cytoplasm from the environment or by synthesis. As a result osmolarity increases inside the cell and water does not move out of the cell.
  • Another way is to make potassium ions selectively move inside the cell. The osmolarity is again increased by the influx of ions and hence the organism does not desiccate.

Are most mutations bad?
nikdorinn [45]

Answer:

Mutational effects can be beneficial, harmful, or neutral, depending on their context or location. Most non-neutral mutations are deleterious. In general, the more base pairs that are affected by a mutation, the larger the effect of the mutation, and the larger the mutation's probability of being deleterious.
