Photosynthesis and glucose metabolism are able to use energy from the sun or glucose molecules to push hydrogen ions against the

ir concentration gradient. This stored energy can then be harnessed to synthesize ATP. The process of pushing hydrogen ions across the membrane against their gradient is an example of which of the following?

Answer:

Osmosis

Explanation:

The osmosis is a movement from somewhere with a lower concentration of a substance to somewhere with a higher concentration of the same substance. Against the concentration gradient. It occurs through a semi permeable membrane which prevents a non desired substance cross it. Also, it's very important to biological process.

Why does the lack of snow in the mountains make drought cycles worse
expeople1 [14]

Answer:

lack of snow in the mountains makes drought cycles worse because mountains are a natural part of the water cycle.

Explanation:

Mountains play a critical part In the water cycle by capturing moisture in the air and it precipitates as snow and when it does this the snow will melt in the warmer seasons and flow down stream then following the rest of the water cycle if we didn't have this then the streams would run less and it would greatly disrupt the water cycle.

What is the pH of a solution with an [H+] of (a) 5.4 x 10-10, (b) 4.3 x 10-5, (c) 5.4 x 10-7?
IgorLugansk [536]

Answer:

a. 9.2

b. 4.4

c. 6.3

Explanation:

In order to calculate the pH of each solution, we will use the definition of pH.

pH = -log [H⁺]

(a) [H⁺] = 5.4 × 10⁻¹⁰ M

pH = -log [H⁺] = -log 5.4 × 10⁻¹⁰ = 9.2

Since pH > 7, the solution is basic.

(b) [H⁺] = 4.3 × 10⁻⁵ M

pH = -log [H⁺] = -log 4.3 × 10⁻⁵ = 4.4

Since pH < 7, the solution is acid.

(c) [H⁺] = 5.4 × 10⁻⁷ M

pH = -log [H⁺] = -log 5.4 × 10⁻⁷ = 6.3

Since pH < 7, the solution is acid.
