Answer:

Acids are sour, gives burning sensation, generally sticky, reacts with metals to produce hydrogen gas. Although bases are opposite as they are bitter, generally odorless (except ammonia), they are slippery; bases react with fats and oils. In phenolphthalein, indicator acids remain colorless, and base gives pink color.

Explanation:

An acid is a substance that releases hydrogen ions into an aqueous solution. A base is a substance that releases hydroxide ions.

https://quizizz.com/admin/quiz/5c9100e1202f89001c843569/stages-in-aquatic-ecological-succession

The event described, where a layer of humus covers the sandy bottom of the lake and affects the fish populations, is an example of succession.

Succession is the process of ecological change over time in a particular area. It involves a series of predictable and sequential changes in the composition and structure of an ecosystem.

In this case, the gradual accumulation of humus, a layer of decomposed organic matter, is altering the habitat conditions in the lake.

The decline in the populations of black bass and bluegill, which build nests on the sandy bottom, can be attributed to the changing habitat.

The humus layer is likely making it difficult or impossible for these fish to construct their nests. On the other hand, fish that are capable of making nests in humus, possibly adapted to this type of substrate, are increasing in numbers.

Therefore, the observed changes in fish populations and the altered habitat due to the accumulation of humus indicate a shift in the ecological community over time, which is a characteristic of succession.

Tropical rainforest, temperate deciduous forest, temperate rainforest

I'm not too sure if the temperate forest is more diverse than the rainforest, so sorry if I'm wrong. Tropical rainforests are the most diverse because of the humidity, which is water. The water helps the soil stay healthy, which makes more plants, which makes more animals and insects.

I hope this helps! Good luck!

The biomes in order from the greatest to least diversity will be tropical rainforest, temperate deciduous forest, and temperate rainforest.

Tropical rainforests refer to the rainforests that occur in areas that have no dry season.

The temperate deciduous forest refers to a biome that always changes. It has seasons such as winter, spring, summer, and fall.

Temperate rainforest refers to the broadleaf or coniferous forests that receive heavy rain. This condition supports ferns, shrubs, etc.

It should be noted that the biome with the greatest diversity is tropical rainforest while the least is the temperate rainforest.

True

Explanation:

The main difference between glucose and ATP is that Glucose is a storable form of energy, while ATP is a usable form of energy.

Glucose is storable form of energy because it can't be used as energy until it can be broken down by mitochondria of the cell while on the other hand, ATP is the usable form of energy which we can get from the break down of glucose molecules. Our cells use ATP as a fuel to do various activities of the cell so we can conclude that in glucose, energy is present in stored form whereas ATP is used as energy in various activities.

Answer:

I think its C but I am not sure, I hope this helps :)

Explanation:

The statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).

Diffusion (both facilitated diffusion and simple diffusion) refers to the movement of substances across biological membranes from an area of high concentration to an area of low concentration.

Facilitated diffusion and simple diffusion are two types of passive transport that do not require energy to move molecules/ions in favor of a concentration gradient.

In facilitated diffusion, specific membrane proteins known as carriers or channels help to the movement of substances in favor of a concentration gradient.

Conversely, in simple diffusion, small molecules (e.g. CO2 and oxygen) freely diffuse across a selectively permeable membrane in favor of a concentration gradient.

In conclusion, the statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).

Explanation:

lol just did it

and pls give me thanks

The circulatory system is the system which consist of blood vessels, heart, and blood. The main function of this system is the transport of oxygen and minerals to all the cells of body. Thus, the correct option is D.

The circulatory system of body consists of all the blood vessels, blood and heart. In this system, blood travels through different blood vessels (arteries, veins, and capillaries) in all parts of the body.

The blood is the main fluid of the body that contains hemoglobin protein which is responsible for the transport of oxygen and carbon dioxide in the body. The blood exchanges gases at the surface of alveoli in the lungs and sends the blood to the heart, heart pumps the blood to all the cells of body.

Therefore, the correct option is D.
