Semi-permeable substances allow certain things to pass through, but others can not. Such as coffee filters, the hot water and newly made coffee can pass through, but the coffee grinds can not. These specifically allow the passage of a solvent, but not many solutes.

PLEASE HELP! ILL GIVE YOU A MEDAL AND FAN YOU!

A cladogram is a type of graph that shows how closely related different types of organisms are in an evolutionary context. It resembles a tree, with various organisms being placed at the end of each branch. If two organisms have a close common branch, they are more closely related than those who have more distant branches. Since DNA, or corresponding protein sequences are more similar in closely related species, and more different in more distant species, a biologist can use those sequences to numerically determine how closely related three species are.

Glycolysis is the first step of cellular respiration, in which glucose is used to generate ATP to power the cell. The major chem
lutik1710 [3]

Answer:

The correct answer is b. C6H12O6 -> 2 C3H4O3+2 H+

Explanation:

Glycolysis occurs in both the condition aerobic and anaerobic so it does not require oxygen. In glycolysis, one glucose molecule is converted into two pyruvate( 2 C3H4O3) and two 2 ATP, 2NADH, and 2 H₂O are produced.

Initially, 2NAD⁺ is produced during glycolysis which is reduced to produce 2NADH and 2 H⁺. Therefore the correct equation is  C6H12O6 -> 2 C3H4O3+2 H+.

Then this pyruvate is used in the Kreb cycle which is required for the complete breakdown of glucose into carbon dioxide and water and this process occurs in aerobic conditions. Complete oxidation is important to produce more energy from partially oxidized glucose.
