How do humans generate energy when oxygen is not available?

a. Using Kreb’s Cycle only
b. Using the Electron Transport Chain only
c. Using alcoholic fermentation
d. Using lactic acid fermentation

Answers

Answer 1
When Oxygen is not available, the cell is forced to produce energy (=ATP) through ANAEROBIC processes, that produce much less energy (about 15 times less), than AEROBIC processes. ... The electron transport chain (ETC) allows the cell to produce energy (ATP) by creating a proton gradient across the mitochondrial membrane. So B.

A truck was carrying a substance in a tank. The molecules of that substance were moving away from each other. The truck parked overnight in a place where energy transferred out of the substance. In the morning, the substance was a gas. How were the molecules moving in the morning?

Answers

Answer:

The gases will be together since they do not possess kinetic energy

Explanation:

let us use the kinetic theory of matter to explain the condition of the gas in the morning.

During the day, the atmosphere can be very hot so the gases tend to be in constant random motion, hence they will move away from themselves because they possess kinetic energy.

In the morning the temperature of the atmosphere is relatively low and the vehicle is not in motion, hence the gases will move together because they no longer possess kinetic energy anymore

C. Two slabs of rock slide past one another.
D. One slab of rock breaks into two pieces.

Answers

Answer: C. Two slabs of rock slide past one another.

Explanation:

Shear stress is one of four stresses that act on the Earth's crust with the other three being Confining, Compression and Tension.

Shear stress is the result of two parallel forces moving in opposing directions to each other. It is the force that results in two slabs of rock sliding past one another.

C. have net movement OUT of the tube, this is a hypotonic solution compared to inside the tube
D. have no net movement, this is an isotonic solution compared to inside the tube.

Answers

Answer:

The correct option is D.

have no net movement, this is an isotonic solution compared to inside the tube.

Explanation:

It will have no net movement, this is an isotonic solution compared to inside the tube because isotonic solution is a solution that has the same osmolarity or solute concentration in both solution, which allow free water movement across the semi permeable memberane on both solution i.e the concentration of the two solution are mostly the same.

which describes a difference between a positive and negative feedback loop?
a. the output of a system stimulates another cycle of the system only in a positive feedback loop.
b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.
c. the output of a system maintains conditions around a set point only in a positive feedback loop.
d. the output of a system signals the system to disregard the stimulus only in a negative feedback loop

Answers

Answer: b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.

Explanation:

In the negative feedback loop, the feedback reduces the excessive response of the stimulus for example regulation of body temperature, and control of blood glucose level. In the positive feedback loop, the response of a stimulus is intensified. Example, positive feedback is the childbirth and blood clotting. According to the negative feedback loop the output of the system keeps the internal body environment constant with respect to the changes in the external environment hence, maintains the homeostasis.

Answer:

b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.
