Answer:
Soil condition directly affects crop growth.
Explanation:
Soil condition affects the crop growth directly. If a soil is in fertile condition then the growth of crop which is growing in such soil will be good but if the soil is infertile then the crop will not grow to its fullest. A fertile soil is the one which has optimum condition for growth of a crop like suitable pH, moisture retention capacity, good amount of nutrients & minerals like nitrogen, phosphorus, sodium, potassium, magnesium etc. If a soil is rich in all these constituents then the crop which is growing in this soil will be healthy.

32) is A it pointing arrows out of the cell so everthing need to go out cell A has more insde then out so think ATP as a force pushing it out. And B there more in then out so it can move out easily:
