TRUE OR FALSE:The amount and type of precipitation in temperate rainforests is the same as tropical rainforests.

Answers

Answer:

The given statement is false.

Tropical rainforests are located near the equator and receive precipitation generally in the form of rain. These forests receive a large amount of precipitation throughout the year which can range from 80 inches to 400 inches in a year.  

Temperate rainforests are located on higher altitudes as compared to the tropical rainforests. They receive precipitation in the form of rain and snow. They receive less amount of rain as compared to tropical rainforests. They receive precipitation which lies between 40 inches and 60 inches in a year.

Thus the amount and type of precipitation in tropical and temperate rainforests are different.


definitely false. a tropical rainforest would have much more precipitation.

Suppose you use a microscope to look at a cell from the leaf of a tree. What structure will you see that would not be found in a cell from your fingernail? A. mitochondria B. cilia C. cell wall D. ribosomes

Answers

Cell walls made of cellulose are present in plant cells. Human cells (skin, fingernails, muscle, etc.) do not have cell walls. Both plant and human fingernail cells have ribosomes and mitochondria. There are no cilia on either of the cells. Therefore, answer C is correct. Hope this helps! :)

Answer:

c. cell wall

Where does the most absorption of nutrients take place?1. liver
2. small intestine
3. large intestine
4. stomach

Answers

The most absorption of nutrients take place in small intestine. The correct option is B.

Thus, The digestive system's small intestine is where the majority of nutrition absorption takes place.

Villi and microvilli, small finger-like projections that line its walls, significantly increase the surface area that can absorb nutrients.

These structures make it easier for nutrients like carbs, proteins, lipids, vitamins, and minerals to enter the bloodstream and be carried to the cells of the body where they can be used for energy and other purposes. The liver and other organs process the nutrients that have been ingested after that.

Thus, The most absorption of nutrients take place in small intestine. The correct option is B.

What is a climax community

Answers

Answer:

An extreme disturbance that only affects the organisms above the ground.

Explanation:

Final answer:

A climax community refers to the final, stable stage in the ecological succession of an ecosystem. An example is a mature forest ecosystem with a stable species balance that can self-perpetuate as long as the environment remains unchanged.

Explanation:

A climax community is a term used in ecology to describe a stable stage in the ecological succession of an ecosystem. To put it simply, it is the final stage of succession, wherein the species of plants, animals, and fungi are balanced and capable of self-perpetuation without further change in species composition. This state is achieved over a long period through the natural evolution of the ecosystem and it persists as long as the environment remains unchanged.

For example, in a forest ecosystem, where succession might begin with pioneer species like lichens or moss, the climax community would be a stable forest populated by trees that are capable of reproducing there, like oak or beech trees. This forest would also contain a variety of animal species that have adapted to the conditions of the forest and are part of a balanced food chain.
