Answer:
Some of the hydrogen bonds with other elements, but most of it remains free hydrogen. Both hydrogen and helium are light elements, so they will tend to evaporate into space over time. ... But the gravity of Earth isn't strong enough, so Earth's early atmosphere of helium and free hydrogen evaporated into space.
Explanation:
Answer: C
Explanation:
Pyruvate dehydrogenase complex (PDH) is covalently modified by phosphorylation by PDH kinase and dephosphorylation by PDH phosphatase.
The dephosphorylated form of the enzyme is active. Hence activators of PDH kinase like ATP, NADH and acetyl CoA inhibits the PDH reaction
PDH phosphatase is activated by Ca++, Mg++ and AMP; this will increase the rate of PDH reaction where as PDH kinase is inhibited by Ca++. When there is adequate ATP and acetyl CoA the enzyme is inhibited.
Answer:
Producer is the answer
Explanation: they take sunlight to produce food aka photsynthesis. Plants are a great example of this!
The correct answers are <span>rice, wheat, and corn.
These foods are considered to hold nutrients that may suffice an individual's body system. They can also make an individual's stomach full easily, when eaten in large quantities. They are considered to be heavy food, while corn can be hard to digest at times.</span>
