The answer to number 4 is D
Answer:
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%.
D)Ethically conducted science seeks to inform rather than influence policy
Gene- a thread like molecule in the nucleus composed of DNA
allele- alternate forms of a specific gene
trait- a genetic characteristic of an individual
chromosome- a portion of DNA which codes a specific heredity trait

Enzymes can either help break a substrate molecule down to smaller ones or help substrate molecules join to form a larger one. They work as catalysts by reducing the activation energy of the reaction by providing an alternate pathway for it. The enzymes are specific with their substrates.
