What is soil salinization?Soil salinization is defined as the accumulation of water-soluble salts within soil layers above a certain level.
Now, an Increase in soil salinity will lead to total crop failure in a field due to the fact that plants need to take up water from the soil for growth and development. However the salinity levels of this soil will draw water from the plants by osmosis since the soil water will be hypertonic to the plant's cells cytoplasm as well as seeds.
In osmosis, water moves from the hypotonic solution to the hypertonic solution via a semi-permeable membrane until osmotic equilibrium is achieved. Thus, planted seeds will find it hard to germinate and plants will wilt and die as a consequence.
The missing options are;
A) Forests are being cleared as land is re purposed for agricultural uses, which reduces biodiversity in the region.
B) Land is being farmed so intensively that soil nutrients are degraded to the point that crops will not grow.

How many people are within receiving distance of the broadcast signal? use 3. 14 for pi. Select from the drop-down menu to correctly complete the statement. There are about choose. People within broadcast distance of the radio station.
Answer:
Explanation:
Calculate the number of square miles if d = 120 miles
d = 120 miles
r = d/2
r = 120/2 miles
r = 60 miles
Area of radio station coverage. = pi * r * r
Area of radio station coverage = 3.14 * 60 * 60 = 11304 square miles.
1 square mile contains 100 people
11304 square miles contain x people
