Answer:

Explanation:

For this, I used process of elimination!

Lipids use most energy, and nucleic acids store RNA and DNA, which is hereditary information. None of the other answer included that, so A should be correct!

I hope this is enough, but I can help more if you'd like!

How do living things make use of the energy stored in food molecules?

ipn [44]

Answer:
The energy stored in food molecule (glucose) is released in he process of respiration.

Explanation: Respiration is a cellular process in which glucose molecule is broken down into carbon dioxide, water and ATP is produced as end product. Respiration consists of following main steps:
1. Glycolysis: It occurs in the cytoplasm of cell, and each glucose molecule is converted into two pyruvates with help of ATP.
2. Formation of Acetyl coenzyme A: It is a connecting link reaction between glycolysis and Kreb cycle. In this phase Each pyruvate react with Coenzyme A to become acetyl coenzyme A.
3. Kreb Cycle: It occurs inside mitochondria. In this cycle each acetyl coenzyme A with fixed with CO to produce citrate which undergo in a cyclic reaction to produce ATP and NADH. .
4. Electron transport chain: It is the last step of respiration which complete in mitochondrial membrane. In this phase most of the energy is produced along with H₂O as by product.

Although meat lacks cellwalls, repeated freezing and thawing

IgorC [24]

Answer:

Lysosome

Explanation:

Freezer burn occurs due to the sublimation of ice in unprotected meat rich in muscles during long-frozen storage. It appears after thawing. The ice crystals rupture the lysosomes which in turn contain hydrolyzing enzymes.

Leakage of the hydrolytic lysosomal enzyme causes freezer burn and affects the appearance of the frozen meat. The hydrolytic enzymes of lysosomes partially digest the cells which in turn impart bad flavor to the stored food.

Polar bears live in the arctic. the arctic is their select one:

Vadim26 [7]

Option C Habitat.... Polar bears are only found in the Arctic. The most important habitats for polar bears are the edges of pack ice where currents and wind interact, forming a continually melting and refreezing matrix of ice patches and leads (open spaces in the ocean between sea ice).

While taking a walk around the neighborhood, a student walks into a tree branch and cuts their arm. Which explanation BEST descr

DaniilM [7]

Answer:

Explanation:

First off, humans are considered animals, and since animal cells don't have chloroplasts, A and D are immediately incorrect. B is incorrect because lysosomes eject enzymes that digest materials in the cell, and to heal skin, you dont need to digest anything/ use enzymes to get rid if materials. That means the answer is C. The nucleus is the control center for the cell, so it tells the cell what to do. The mitochondria creates energy for the cell, and since it takes energy to heal, this answer is correct. (Tip- I find that using process of elimination in biology questions helps a lot.) Good luck!

What happens if you drop some type of liquid on a cable such as a phone charger? Can you get hurt? Can you still use it?

ipn [44]

It really just depends. If the liquid got in any crevices it might not work. If it wasn't plugged in, no you cannot get hurt. But I've had chargers that I spilled water on and they still work fine, but again, it depends. Like if there's a tear in the cord that liquid got in, then no it probably won't work anymore.
