For #1, the last choice is correct. A geocentric model means that the earth is the center of the universe while all other bodies orbit around it. A heliocentric model means that the sun is the center of the inverse while the other bodies orbit around it. The shared feature is that the other bodies in space move in circular orbits.
For #2, the first answer is correct. When the moon is between the earth and the sun, positions X and Z are being pulled by the moon’s gravitational force, creating high tides at these places. However, positions W and Y are experiencing low tides because no gravitational pull is making them high.
Last one: blood going to the cells receives co2
Answer:
In high glucose-NADH and FADH2
In depletion case- NAD+ and FAD+2.
Explanation:
MCAD (Medium-chain acyl-CoA dehydrogenase) deficiency may be defined as inherited disorder in which the body's ability to breakdown the fat decreases and converting them in energy.
Excess glucose stores: The presence of excess glucose prevents the proton gradient to transfer electrons in the electron transport chain. This causes the buildup of NADH and FADH2.
Low energy state: This state needs ATP that decrease the carriers and causes the buildup of NAD+ and FAD+2.
