Answer:
Roughly around 24 miles per hour or 11 meters per second
Explanation:
The question is <u>incomplete,</u> options are given below:
A. A tropical area with moderate rainfall
B. A temperate forest
C. A steep slope
D. A river delta
Answer:
<em>C.</em><em> A steep slope</em>
Explanation:
Erosion is a <u>weathering process</u> that causes removal of the top layer of sediments from any geological material (rock, plain area, etc) and then transports that material to another place. This process is governed by the combined action of wind, water (precipitation), gravity, and other meteorological parameters.
For this question, four options are given among which rate of erosion would be faster than the rate of soil formation for a steep slope. For a steep slope, the movement of water and wind would be stronger along with high gravitational pull as compared to the tropical area, river delta, and temperate forest. In principle, in the temperate forest, the erosion would be lowest due to the presence of plant roots that support the soil material to stay aggregated and resist against weathering.
Answer:
I think it's two x chromosomes.
Answer:
These crops can fix nitrogen into usable nitrates.
Explanation:
There are certain crops which are called cover crops, specifically legumes like peas, vetch,clover and winter field beans . Farmers grow these crops during winter before the growth of actual target crops like cabbage etc which are thirsty for Nitrogen.
What is special about these cover crops is their ability to fix nitrogen into the soil from the atmosphere. There are various ways through which these leguminous crops can fix nitrogen into the soil:
- Some legumes like hairy vetch and crimson clover, may fix upto 100 pounds of nitrogen per acre for the utilization by the crop growing in same soil next season.
- Other legumes like red clover and bigflower vetch can fix from 30 to 80 pounds of nitrogen per acre .
- Now how the legumes fix nitrogen is through a symbiotic relationship with soil-dwelling bacteria. These are the bacteria that dwell in soil and take nitrogen from atmosphere and provide this nitrogen to leguminous crops through roots which later fix this nitrogen into nitrates.In return, the bacteria can get food in the form of carbohydrates from legumes.
This phenomenon confers the leguminous crops with an ability to fix nitrogen in the soil that can be used by the nitrogen requiring crops like cabbage when grown next season in same soil.
Hope it help!
