Answer: Recombinant DNA is the correct answer
Answer:
Solar energy is used today in many ways. The most common form of solar energy used today are photovoltaic solar panels, which uses the sun's light to create electricity. They are commonly used as a secondary source of power.
Explanation:
Alleles. Alleles are the "same" genes, but provide a variation of the intended function.
Answer:
f(x)=5/4(4/5)^x
Explanation:
For example, a function stretch if it was multiplied by a number higher than 1. Assuming the base number is 1, if it becomes 5 then it is stretched. If the number become 1/5(less than 1) it is called compressed. Exponential decay function has ratio <1.
Answer:
1- Soil filters our water, provides essential nutrients to our forests and crops, and helps regulate the Earth's temperature as well as many of the important greenhouse gases.
2- Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, animals, and humans.
3- Humans affect erosion rates in a number of ways across the globe. ... Human activities such as repeatedly walking or biking the same trails or areas can also contribute to erosion slowly over time. Forest fires also contribute to soil erosion, as vegetation previously holding the soil in place is often destroyed
4 - 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.
5 - You can reduce soil erosion by:
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.
