Which of the following are necessary for a seed to germinate?

The question lacks options, the options are:

A. moisture content of seed must be at least 9%

B. Moisture content of the seed must be less than 9%

C. certain enzymes in the seed are activated

D. temperature must be above 80 degrees

E. temperature must be below 80 degrees

The answer is A

Explanation:

Germination is practically the very first step of every seed-producing plant. It is the process whereby seeds sprout or begin to grow. Germination requires certain conditions to be met in order to occur. This conditions include presence of moisture in the soil etc.

The water is absorbed by the seed helps to soften the seed coat, which protects the seed from damage. The seed coat ruptures, causing the emergence of growth structures from the seed. In general, seeds need water to activate their dormant physiology. Hence, the moisture content of the seed must not be lower than 9%.

a warm, wet climate will produce the highest rate of weathering. the warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering (figure below). this happens because plants and bacteria grow and multiply faster in warmer temperatures.

is this a psat question, if so do not cheat try your best.
