Answer:
The answer is C. The cell took in another ancient prokaryotic cell, which began living inside it.
Explanation:
- The Endosymbiont Theory explains the evolution of membrane bound organelles such as mitochondria and chloroplasts.
- According to the theory, mitochondria evolved when an ameoba like organism engulfed bacteria capable of cellular respiration.
- Similarly, chloroplasts were developed when the ameoba like organism engulfed cyanobacteria or blue-green algae capable of photosynthesis.
- These organisms survived inside the ameoba over millions of years to develop into mitochondria and chloroplasts.
- The fact that mitochondria and chloroplasts have their own circular DNA and ribosomes is evidence of the endosymbiont theory.
Answer:
Biogeochemical cycles and the rock cycle allow nutrients to be recycled through the abiotic and biotic zones of Earth. They are responsible for the cycling of oxygen, carbon dioxide, phosphorus and nitrogen between the biosphere and the rest of Earth. Hope this helped!
Explanation:
The monoamine oxidase (MAO) inhibitor is an enzyme inhibits monoamine oxidase that is involved in the breakdown of serotonin, norepinephrine, and dopamine at the brain.
<h3>Neurotransmitters and their uses</h3>
Neurotransmitters are the chemical that are used to transmit electrical signals from a nerve cell to the target organ.
Some examples of neurotransmitters are:
- gamma-aminobutyric acid (GABA),
- norepinephrine, and serotonin
Monoamine oxidase (MAO) inhibitor enzyme makes the neurotransmitters available at the brain by preventing their breakdown by the monoamine oxidase.

Answer:
New findings and new evidence about a scientific theory can change the aspects of this scientific theory and in some cases, it can be proved as wrong or can be supported by more strong evidence that can prove its liability.
New technology allows scientists and researchers to study various untouched aspects and leads to find new evidence to support or prove the theory can be either change or unproven.
Thus, new technology and experimental methods can lead to changes in theories.
