Question 4

Juliette [100K]

Answer:

In eukaryotes, thousands of chemical reactions are able to take place in separate compartments called organelles.

Explanation:

Organelles are specific cellular structures that are the means of compartmentalizing the various functions that occur within cells.

Examples of organelles and their functions are:

- Nucleus: contains DNA and in it occur the replication of this molecule and its transcription into RNA.

- Rough endoplasmic reticulum: protein synthesis and conjugation of these molecules occurs.

- Mitochondrion: houses all oxidative phosphorylation reactions and the electron transport chain for ATP synthesis to occur.

The organelles are then the structures that allow the development of the multiple functions that a cell has.

The other options are not correct because:

Bacteria is a prokaryotic organism.
Prokaryote refers to simple organisms that lack organelles.
Proteins are biomolecules that allow the structure and function of living beings.

tatyana61 [14]

The answer is Vaccination.
Acquired or adaptive immunity is the body's third line of defense. This is protection against specific types of pathogens. Acquired immunity may be either natural or artificial in nature. Both natural and artificial immunity have passive and active components. Active immunity results from an infection or an immunization, while passive immunity comes from naturally or artificially gaining antibodies.
