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%.

Answer;
all individual variation is due only to environmental factors
A population of organisms will not evolve if all individual variation is due only to environmental factors.
Explanation;
-Evolution of organisms is influenced by several factors which include; natural selection, random genetic drift, mutation, and gene flow.
-Mutation is a random heritable change in a gene or chromosome, resulting from additions, deletions, or substitutions of nitrogen bases in the DNA sequence. Gene flow works to decrease the variation between the two populations.
-Genetic drift is the random change in allele frequency from one generation to the next.. Natural selection is the process by which some organisms have a greater chance of surviving and reproducing than others due to features that are better adapted to the environment.
Answer:
Prophase I, prometaphase, metaphase I, anaphase I, telophase I, and cytokinesis, interphase, prophase II, prometaphase II, metaphase II, anaphase II, telophase II, and cytokinesis.
Explanation:
Prophase I, prometaphase, metaphase I, anaphase I, telophase I, and cytokinesis, interphase, prophase II, prometaphase II, metaphase II, anaphase II, telophase II, and cytokinesis are the 12 phases of cell division that occurs in the sex cells of human body. These double phases allow the sex cells to produce four daughter cells from a single parent cell but the chromosomes number is half in each daughter cell.
