Osmosis requires energy

True
Or
False

Answers

Answer:

Diffusion and osmosis don't require the cell to expend any of its own energy, as they are passive processes. As we know both are passive processes and yet (in basic, short terms) diffusion is higher to lower and osmosis is lower to higher, so movement to concentration doesn't determine whether it is active or passive.

when do birds use their teeth????

Answers

Answer:

to eat worms

Explanation:

Answer:

Birds do not have teeth, however...

Explanation:

[tex]--------------------------------------------[/tex]

According to The Cornell Lab, "Birds do not have teeth, however, they may have ridges on their bills that help them grip food, but this does not count as teeth. So what about birds that have “tooth” in their name, like Double-toothed Kite? Some birds of prey have a sharp ridge or “tomial tooth” on the bill that they use to bite into their prey when subduing it. But these modifications to the bill surface are not considered the same thing as individualized teeth seen in other animals."

Answers

Glycolysis is the process of breaking glucose into energy. If oxygen is still available for cellular respiration after glycolysis then, the Krebs cycle and oxidative phosphorylation will occur.

What is Kreb's cycle?

Kreb's cycle (TCA) is the important cycle in aerobic organisms that produce energy from acetyl CoA into NADH, ATP, and FADH₂ through the proteins, carbohydrates, and fats.

In oxidative phosphorylation, the ATP synthesis is connected to the ETC and along with the citric acid, the cycle produces more energy in the form of ATP in the presence of oxygen.

Therefore, the Kreb cycle and oxidative phosphorylation occur if oxygen is still available after the process of glycolysis.
