What type of mutation occurs when a nucleotide is added to the DNA?

Yanka [14]

Answer:

A frameshift mutation.

Explanation:

A frameshift mutation is when one adds an extra nucleotide to a series of nucleotides. This will mess up the order of the nucleotide, thus when it forms the codons, and eventually, the amino acids; all of the codons are wrong, thus all of the amino acids are wrong.

In this situation, an extra nucleotide is added to a sequence of DNA, this results in all of the other nucleotides getting pushed over by (1). Thus, all of the nucleotides form the wrong codons and the wrong amino acids. Therefore, a frameshift mutation has occured.

How do fungi beneﬁt from being able to reproduce both asexually and sexually?

Alekssandra [29.7K]

Asexual reproduction is an advantage because they don't need to depend on contacting a suitable mate, or expand energy producing gametes and attractions, in order to spread .

sexual reproduction is an advantage because it enables the exchange of genetic information and produces variety in the offspring that makes them more resilient and capable of adapting to changes in their environment .

If a cell's MITOCHONDRIA were to stop working, what would happen to the cell right

shepuryov [24]

Explanation:

If a cell's mitochondria was to stop working, energy would not be produced.

This is so because The Mitochondria as part of the cell is the power house of the cell, it produces or gives energy to the cell so if were to stop working, energy will not be produced.

The hay included as part of the culture medium provided a food source for bacteria. Bacteria are a good food source for some typ

lions [1.4K]

Answer:

Protozoans → would not have survived because they have no way to produce their own food → Heterotrophs
Algae → would have survived without this food source → Heterotrophs

Explanation:

The protist kingdom is composed of two main groups. The principal difference between them is that algae can produce their own food, while protozoans need to ingest other organisms or organic molecules to survive.

Algaes are autotroph
Protozoans are heterotroph

Protozoans:

Microscopic unicellular organisms, eukaryotic and heterotrophs -predators or detritivores-. Most of them are aquatic free-living organisms, but some species are parasites. They feed on bacteria, other organic wastes, and other microscopic organisms. The phagocytosis process is normally used to ingest the food, invaginating their cell membrane.

Algae:

Eukaryotic micro- or macroscopic organisms. Autotroph and photosynthetic. They might be either unicellular or pluricellular. They use sunlight to synthesize organic matter from water, CO₂, and mineral salts. Unicellular ones can be free-living or associate with others to form colonies. They are part of the phytoplankton and are ingested by heterotrophic organisms. Pluricellular algae do not create real tissues but they compose a tale. The depth at which they inhabit depends on the pigments they produce. All of them inhabit fresh or sea waters.
