Answer:
-60°C
Explanation:
According to this question, a material was cooled from 100ºC to 40ºC.
The temperature change, which is symbolized by ∆T = final temperature - initial temperature
That is, ∆T = T2 - T1
In this question, T2 = 40°C, T1 = 100°C
Hence, ∆T = 40°C - 100°C
∆T = -60°C
Answer:
A sugar called deoxyribose.
Explanation:
DNA is made up of molecules called "nucleotides". These are:
- A phosphate group
- A pentose sugar [deoxyribose]
- A nitrogen-containing base [adenine, thymine, guanine and cytosine]
Thus the first option is the right answer.
Reasons why the other options are wrong:
"A plasma called haemoglobin" is wrong as plasma and haemoglobin are related to the blood.
"A chemical called nucleic acid" is wrong as it is not what DNA's made up of. DNA and RNA are nucleic acids themselves.
"An acid called chlorophyll" is wrong as chlorophyll is related to plants.
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.
