The relative humidity would be ________% if the actual water vapor in the air was 10 grams per cubic meter, the air's capacity t
lys-0071 [83]

Answer: The Relative humidity is 50%

Explanation: Relative humidity is the ratio of the air’s water vapour content (the actual amount of water vapour in the air) to its water vapour capacity at a given temperature. It depends on temperature and the pressure of the system of interest and it is usually expressed in PERCENTAGE; the higher the percentage, the more humid the air/water mixture.

The formula of Relative humidity (%) = (water vapor content / water vapor capacity) x 100%

Where: Water vapour content is the actual amount of water vapour in the air. Which is 10g/cm³ from the question above;

Water vapour capacity is the air's capacity to hold water vapour. Which is 20g/cm³ from the question above.

Therefore, RH(%)= (10g/cm³ / 20g/cm³) x 100 = 0.5 x 100= 50%

This means that the air contains half of the water vapour it could hold at 20 degree Celsius.

During glycolysis, glucose is broken down into two molecules of pyruvate.
mojhsa [17]

Answer:

<em><u>Glycolysis produces pyruvate, ATP, and NADH by oxidizing glucose.</u></em>

Explanation:

Glycolysis is an oxidation reaction in which glucose reacts with oxygen molecules and oxidized. By oxidizing glucose, it produces pyruvate, adenosine triphosphate (ATP) and nicotinamide adenine dinucleotides (NADH). Glycolysis has two phases. In the first phase, 2 ATP molecules are invested for the phosphorylation of glucose to break down into a simpler one. In the second phase of glycolysis, 4 ATP molecules are earned back with 2 NADH and a simpler form of glucose (6C) to pyruvate (3C) by oxidizing glucose.

Are there any similarities between this Galapagos research and Darwin’s research? Explain your answer.
Usimov [2.4K]

Answer: This modern-day researcher used some of the same theories that Darwin proposed. Like Darwin and his finches and tortoises, this scientist understood that the Galapagos cormorants inherited flightless wings. Darwin eventually discovered that his Galapagos finches likely evolved from other species of finches on the mainland. This evolution was similar to how the flightless Galapagos cormorants evolved from other species of cormorants.
