Answer:

B.

Explanation:

Fossil fuels definitely harm the environment, and their supply is depleting. So that takes out answers C and D, leaving A and B. The main cause of ozone depletion and the ozone hole is manufactured chemicals being released into the air. While CO2 from fossil fuels does have an effect on worsening the hole, it has a much higher effect on global climate change.

The concentration of N2 in blood at 37 °C (body temperature) and atmospheric pressure (partial pressure of N2 = 0.80 atm) is 0.0
devlian [24]

Answer:

volume  = 0.285 L

Explanation:

Henry constant is given as

Henry constant  =  \frac{C}{P}

Where C  is concentration

P is atmospheric pressure

Henry\ constant = \frac{0.00056}{0.80} = 0.0007 M/atm

when atmospheric pressure 4 atm

solubility = K_H\times P

              = 0.0007 \times 4 = 0.0028 M

In 5 litere blood , moles of N_2 = Molarity \times volume

                                                     = 0.0028 \times 5 = 0.014

At surface moles  = 0.0056 \times 5 = 0.0028

Moles of N_2 release = 0.014 - 0.0028 = 0.0112

Mass of N_2 = 0.0112 \times 28 = 0.314 g

T = 37 + 273 = 310 K

VOLUME = \frac{nRT}{P}

= \frac{0.0112\times 0.0821\times 310}{1}

volume  = 0.285 L

Select the correct statements about glycolysis. a) Major products of glycolysis include pyruvate, ATP , and NADH . b) Glycolysis
dalvyx [7]

Answer:

a). Major products of glycolysis include pyruvate, ATP , and NADH

b) Glycolysis is the process by which glucose is converted to two molecules of pyruvate.

Explanation:

Glycolysis is a process in which a glucose molecule is broken down into two molecules of pyruvate. The process of glycolysis occurs without oxygen therefore it can occur in both aerobes and anaerobes.

The process of glycolysis occurs in the cytoplasm of the cell and the products of glycolysis are 2 molecules of pyruvate, 2ATP, and 2 NADH molecule. Then the pyruvate molecule gets into mitochondria which it's complete oxidation takes place. Therefore the right answer is a and b.
