False. Strontium 90 has a half life of only 30 years, and as millions of years pass, about the time fossils have been around, most if not all of any strontium would have decayed.
Answer:
5.37 °C
Explanation:
The optimal condition for most enzymes in the small intestine is 37 °C.
Enzymes are responsible for mediating several biological processes in the human body. The optimal condition for enzymes in the small intestine has an optimum pH of about 7.5 and the temperature is 37 °C, which is the normal body temperature of the human body.
Hence, the correct option is "5. 37 °C".
Electron Carriers such as NADH and FADH are generated during the Krebs cycle (Option D).
<h3>What is the Krebs cycle?</h3>
The Krebs cycle is the second step of cellular respiration, which allows aerobic cell to generate energy in the form of ATP.
The Krebs cycle generates the reduced forms of the carriers NADH and FADH, which are used in oxidative phosphorylation to generate ATP.
In conclusion, Electron Carriers are generated in the Krebs cycle (Option D).

Answer:
The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known organisms. A cell is the smallest unit of life. Cells are often called the "building blocks of life".
El Nino is a climate cycle where the temperature of the Pacific Ocean changes because of movements of air and ocean currents. During this period, the trade winds in the south weaken, causing the warm water to move from the Western region to the Eastern region.
El Nino climate cycle begins when warm water in the western tropical Pacific Ocean shifts eastward along the equator toward the coast of South America.
Opposite of El Nino is La Niña when the waters of the tropical eastern Pacific are colder than normal and trade winds blow strongly than usual.
