<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>C</u>. containing
- <u><em>egg albumen
</em></u>
- <u><em>protease
</em></u>
- <u><em>dilute hydrochloric acid</em></u>
Explanation:
A protease is a kind of peptidase enzyme that breaks down proteins into peptide molecules. As a digestive enzyme it is located in the lining of the stomach where, relative to the hydrochloric acid in digestive juices, the pH is usually low/ acidic.
<em>Enzymes speed up reaction rates by </em><em>providing alternative pathways</em>. By modifying the enzyme composition, supplying more collision energy, and changing the collisions between and the ratio of reactants, certain variables will increase the reaction rate.
Proteases function well at 37℃, the typical internal temperature of the human body- this temperature provides adequate energy for the reaction. Similarly, proteases require low pH for the correct configuration, and beyond this pH and temperature, they may become denatured or simply not function well as catalysts.

Cholera, its a water borne disease.
One dominant and one recessive for each parent is what you were asking for right ?
Answer: A scenario often presented to introductory physics classes is that of a "gravity tunnel" — a tube drilled from one side of the Earth to the other through the planet's center. The answer taught for nearly a half-century for how long a fall through such a hole would take was about 42 minutes and 12 seconds.
Explanation: However, solar and lunar gravity, which also perturb orbiting satellites, would eventually pull you into the tunnel wall anyway [source: Darling ]. Strike a chord: Fun fact: A straight line from any point to any other point through the planet would take the same amount of time to fall through like a tunnel through Earth's center.
