<h3><u>Answer;</u></h3>
A. global temperatures drop several degrees after several massive volcanic eruptions
<h3><u>Explanation;</u></h3>
- <em><u>A mass extinction refers to a widespread and a rapid decrease in the Earth's biodiversity. </u></em>
- <em><u>Mass extinctions may occur due to a number of reasons which includes, asteroid impacts, climate change, massive volcanic eruptions or a combination of all these causes. </u></em>
- <em><u>An example of mass extinction was during the Mesozoic Era, that led to the extinction of dinosaurs, about 65 million years ago.</u></em>
Answer:
<u>In the mitochondrial matrix</u>
<u></u>
Explanation:
The mitochondria is an organelle within the cytoplasm of the cell. It consists of an outer membrane, inner membrane, and matrix containing a gel-like substance. During aerobic respiration in mitochondria, cells break down sugars in the form of glucose into 
(carbon dioxide) and 
(water) to obtain energy in the form of ATP or adenosine triphosphate.
aerobic respiration:
C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
(glucose) (oxygen) (carbon dioxide) + (water)
The Kreb's cycle involves several enzymatic reactions, where pyruvate derivatives obtained from glycolysis, are reduced and oxidized to harvest energy as ATP.
The answer would be true! A table does display data in a row and columns!
Answer: wind power, As with all energy supply options, wind energy can have adverse environmental impacts, including the potential to reduce, fragment, or degrade habitat for wildlife, fish, and plants. Furthermore, spinning turbine blades can pose a threat to flying wildlife like birds and bats.
Prokaryotes are organisms that consist of a single prokaryotic cell. Eukaryotic cells are found in plants, animals, fungi, and protists. They range from 10–100 μm in diameter, and their DNA is contained within a membrane-bound nucleus. Eukaryotes are organisms containing eukaryotic cells.
A cell cycle is a series of events that takes place in a cell as it grows and divides. ... The cell then leaves interphase, undergoes mitosis, and completes its division. The resulting cells, known as daughter cells, each enter their own interphase and begin a new round of the cell cycle. mark brainliest plzz
Explanation:
The term Neurotransmitter describes the chemical substances that make it possible for messages to cross from the synapse of a neuron to the target receptor.
<h3>What are Neurotransmitters?</h3>
- Neurotransmitters are endogenous chemicals that allow neurons to communicate with each other throughout the body.
- Chemical synaptic transmission is primarily through the release of neurotransmitters from presynaptic neural cells to postsynaptic receptors.
- There are a number of neurotransmitters used by the body for different functions, including acetylcholine, norepinephrine, glutamate, GABA, glycine, dopamine, and serotonin.
- Glutamate is the principal excitatory neurotransmitter used in the brain.
- GABA and Glycine serve as the major inhibitory neurotransmitters.
