HELP PLEASE I HAVE A WEEK LEFT OF SCHOOL I DONT WANNA FAIL
Oksana_A [137]

Answer:

I am too lazy to do this, but I am assuming you were supposed to do this in class. I will give you ideas.

Why is soil important?  Soil is our life support system. Soils provide anchorage for roots, hold water and nutrients. Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites.

What is soil erosion?  Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.

what human activities are responsible for soil erosion happening at advance rates?     Ploughing, unsuitable agricultural practices, combined with deforestation and overgrazing, are the main causes of human-induced soil erosion

What are some effects on soil loss?  The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

What can be done to prevent soil erosion?   Maintaining a healthy, perennial plant cover.

Mulching.

Planting a cover crop – such as winter rye in vegetable gardens. ...

Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.

Explanation:  Hope this helps and have a great day

Can someone help me with facts about rainforests? I have to do a project and I'm stumped.
jeka57 [31]
Rainforest cover only 2 % of the total surface area of the Earth but in spite of that about 50 % of plants and animals that live on the Earth live there.

By definition rainforests are forests that recieve high amounts of rainfall so you can actually find rainforests in Alaska for example (other examples: Canada, Asia, Africa, Latin and South-America)

About 1/4 of natural medicines are found in rainforests. 70 % or more of the plants that are used to treat cancer are found only in tropical rainforest on the planet.

Trees in tropical rainforests are so dense that it takes approximately 10 min for the rainfall to reach the ground from canopy.

Select the most accurate statement describing the basic function of the light reactions of photosynthesis. Select the most accur
S_A_V [24]

Answer:

The basic function of the light reactions of photosynthesis is the conversion of solar energy to chemical energy.

Explanation:

In photosynthesis, the light energy is captured by chlorophyll pigment which is present in the thylakoid membrane. Then this light energy is used split water which releases the electron that enters the electron transport chain. Then electrons move through several electron carriers and helps to generates NADPH and ATP.  

These NADPH and ATP are used in the Calvin cycle to fix the carbon into carbohydrates like glucose. Glucose molecules is then used by the plant to get energy source and to make structural components like cell wall. Therefore during photosynthesis solar energy is converted into chemical energy like glucose.
