Rom4ik [11]

Answer:

The correct answer is option c. "frameshift mutations".

Explanation:

The reading frame of a gene is based on base-pair triplets, starting from the start codon until the ribosome encounters with the end codon. Base-pair additions and deletions are collectively referred to as frameshift mutations because they alter the reading frame of the gene. Base-pair additions and deletions break down the original sequence of the gene triplets, which alters the open reading frame and usually results in the production of non active proteins.

4. Discuss the sense organs of cnidarians
HACTEHA [7]

Answer:

To tell the truth I don't know what none of this stuff so I searched it up.

Explanation:

Cnidarian sense organs are thought to be exclusive to the medusa, a point we dispute subsequently. Nevertheless, the sense organs of the medusa are highly developed and distributed across Scyphozoa, Hydrozoa, and Cubazoa. In those hydrozoans with a medusa stage, many have eyes associated with the tentacle base.

Hope that is what you are looking for.
