Answer:
I am pretty sure it is B, weathering and erosion. Hope this helps!
Answer:
Glycocalyx
Explanation:
Most of the eukaryotic cells have a coating outside their cell membrane. This coating is called the glycocalyx. It consists of glycoproteins and glycolipids. The sugar parts of these compounds are in contact with the underlying plasma membrane. The function of the glycocalyx is to protect the cell. Certain specific molecules of the glycocalyx are involved in the recognition of cells so that they can recognize one another to make contact.
Rainwater is normally free from dangerous substances, which makes it perfect for irrigation schemes. Added significant benefit is that it decreases the requirement for fresh water. It is important particularly in regions with low water levels.
Another benefit might water harvesting have in these areas with land erosion due to runoff are as follows;
Reduces Water Shortages
In temperate areas, the strain on public water supply can become hard, even in advanced countries. Rainwater decreases the uncertainty of water shortages. Using rainwater for non-essential actions such as spraying the lawn means less pressure on the supply of safe drinking water.
Replenishes Groundwater
Extensive rainwater harvesting projects with the water collected into storage containers or tanks are important to assure a sustainable groundwater level.
Reduces soil erosion
Heavy rainfall generates erosion because some of the soil is transferred along with the passage of water. Soil erosion exhausts agricultural land of topsoil and nutrients, provides to sediment build up in waterways and, in advanced cases, can turn land inadequate for agriculture. Harvesting rain checks a great chance of soil erosion before it can originate.
Answer:
Ia tidak mempunyai badan fizikal.
Penjelasan:
Jisim udara tidak diukur oleh keseimbangan tuas atau keseimbangan berat yang lain kerana mustahil untuk mengukur jisim udara. Hanya dua sifat udara yang dapat diukur seperti kadar aliran dan tekanan. Imbangan tuas mengukur berat bahan-bahan yang mempunyai badan fizikal sehingga sebab itu jisim udara tidak dapat diukur kerana tidak mempunyai badan fizikal. Udara mempunyai jisim tetapi tidak mempunyai badan fizikal sehingga mustahil untuk mengukur beratnya.
I'm going to make an educated guess and say the answer is A.
