Answer:
NADPH is produced from NADP+. The major source of NADPH in animals and other non-photosynthetic organisms is the pentose phosphate pathway (oxPPP), by Glucose-6-phosphate dehydrogenase (G6PDH) in the first step. The oxPPP pathway also produces pentose, another important part of NAD(P)H, from glucose.
Explanation:
B. Earth is tidally locked, while the moon spins on its axis.
C. The moon is older than Earth by approximately 300 million years.
D. Earth and the moon have nearly the same mass.
Answer:
A
Explanation:
It is believed that the moon was formed shortly (relative time) after the earth was newly formed. This occurred in a massive planet-sized collision that ejected a huge chunk of the earth out into space. The chunk, still within earth gravitational reach, began orbiting the earth becoming the moon. Both earth and moon are slightly more than 4 billion years old.
Answer:
A. Earth and the moon are nearly the same age.
Explanation:
These hypotheses are consistent with the evidence that shows rock from the moon and the earth have nearly the same age and composition.

Answer:
The correct answer is because of gravity and air resistance.
Explanation:
When we speak of free fall, we are referring to something that falls "into the void", and which has no force to oppose such a fall.
Due to the gravity and atmosphere of our planet, this situation is not possible. When an object falls close to our surface, it is very difficult to do it in free fall. Gravity is going to pull this object down, which along with air resistance, will cause the object to fall at a constant speed.
It is a bacterioptrage.
It undergoes a lysogenic cycle.
H.
It does not contain a viral envelope.
J.
It does not kill host cells after infection.
Answer:
The correct option is : It undergoes a lysogenic cycle.
Explanation:
A virus can replicate inside a host cell by two process :
In the lytic cycle, the viral DNA makes copies of itself and manufactures the viral machinery inside the host cell. Eventually, the host cell bursts causing the release of the viruses. In such a condition the varicella virus would cause chicken pox.
In the lysogenic cycle, the DNA of a virus get incorporated into the DNA of the host. The viral DNA might replicate when conditions become favourable and cause diseases. In such a condition, the varicella virus would cause shingles.

Answer:
coronary arteries
Oxygen is supplied to the heart muscle by the coronary arteries. These are the blood vessels that wrap around the surface of the heart: The left main coronary artery branches into the: Circumflex coronary artery, which supplies blood to the back left side of the heart
