Answer:

3. An Apple Turning Brown

Explanation:

When an apple is cut (or bruised), oxygen is introduced into the injured plant tissue. When oxygen is present in cells, polyphenol oxidase (PPO) enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.

Answer:

I believe It's 3. If it isn't it's probably 4, because that also has to do with change. (If I'm being honest none of these really pertain to oxidation, since it has to do with weathering things but eh.)

Hope I could help!

True or false? If the Sun is directly over the shoreline, the water heats up faster than the land, even though both get the same
Arte-miy333 [17]

Answer:

False.

Explanation:

The water can not heat up faster than the land if both receives similar solar radiation because land heats faster than water. Water has a higher specific heat capacity than soil which means that a lot of heat energy is needed to raise the temperature of water by one degree, while on the other hand, soil particles needs little energy to change the temperature of soil by one degree so that's why we can say that land heats faster than water.

JulijaS [17]

Answer:

Potato

Explanation:

Hypertension is a condition developed due to the continuous high or elevated blood pressure in the arteries in the body. The main cause of hypertension is the contraction of the arteries and the consumption of food with a high level of sodium and low level of potassium.

It is suggested that people with hypertension should consume a diet rich in potassium but with a low amount of sodium.  The good source of food with a high level of potassium is baked potato which provides carbohydrates also, salmon, and the banana.

Since the amount of potassium is high in the baked potato, therefore, is the correct answer.
