A mutation is a change in the DNA sequence that can be either beneficial or harmful. 1) B, false.

<h3>What is a mutation?</h3>

A mutation is a stable and hereditably change in the genetic material that introduces new variants.

These changes are unpredictable, and occur due to the action of mutagenic agents that alter DNI sequences.

Different mutagenic agents cause changes in genetic information, increasing mutations over the normal level.

Mutagenic agents cause changes in the base sequences and pairing.

Many of these mutations are eliminated, but some might succeed and be incorporated into each individual, getting to even affect the entire species.

These mutations are the ones that have been selected by natural selection.

Mutations depend on environmental conditions and ecological pressures, and accumulate in time. Mutations can be damaging or beneficial to the organism and might be inheritable or not.

Those favored by natural selection are inherited by the following generations and get to spread.

The statement is False, Option B.

Amiraneli [1.4K]

Answer:

1, 2, and 5

Explanation:

Viruses are pathogenic microorganisms that lack the ability to thrive and reproduce outside of a living host cell. Their structure is simple - they consist of a nucleic acid molecule surrounded by a protein coating and sometimes an outer envelope. They are too small to be seen by a light microscope.

As they are way smaller than living cells, viruses are smaller than organelles as well. They don't have their own metabolism. Their reproduction is not based on division. They don't have any organelles, including the cytoplasm. They are surrounded by a protein coat called the capsid.

Based on this information, we can see that the correct statements are statements 1, 2, and 5.

Plants have chloroplasts and mitochondria. What is the purpose of mitochondria when a cell already has chloroplasts?

slega [8]

Answer:

To turn sugars into energy

Explanation:

$\bf{ \underline{ \large{Functions \: of \: Mitochondria}}}$

Mitochondria are main sites of aerobic respiration. They are miniature biochemical factories where food stuffs are completely oxidised to carbon dioxide and water.
The energy (ATP) produced in the mitochondria helps to perform various energy requiring processes.
Because of the formation of ATP in mitochondria it is called power house of the cell.

$\bf{ \underline{ \large{Functions \: of \: Chloroplast}}}$

Photosynthesis: Light reaction (in thylakoids), Dark reaction (in stroma).
Storage of starch.
