Answer:

a bacterium

Explanation:

<em>Penicillium nonatum is a type of </em><em>bacterium</em><em>.</em>

<u>Bacteria are prokaryotic, microscopic organisms that are capable of adopting different lifestyles based on their mode of nutrition. While some are capable of manufacturing their foods via photosynthesis/chemosynthesis, some are saprophytic in nature while others lives as parasites on living organisms.</u>

Those that lives as parasites are often capable of causing diseases and are therefore called pathogens.

Penicillium nonatum is capable of producing a substance that has the capacity to inhibit the growth of another bacteria. Substances that are capable of inhibiting or killing bacteria are generally known as antibiotics.

Mutations in which of the following cells would get passed on to the next generation?
creativ13 [48]

Answer:

C. I and III

Explanation:

A mutation needs to occur in a gamete cell in order to be passed down to the next generation.

If it occurs in a somatic (body) cell, the mutation will only be present in that organism.

On the other hand, in a gamete cell, the mutation will pass down because gamete cells are directly involved in the genetic makeup of the offspring.

So, since sperm and egg cells are gametes, mutations in those cells would get passed on.

The correct answer is C. I and III
