Basically the seed contains 2 parts, the testa, which is the seed coat that protects the seed and cotelydon, which is the inside of the seed, containing the radical and plumle.
for seed to germinate, we need 3 basic conditions,
warmth, it is the suitable temperature for seed germination, it can influence the activity of enzymes. providing a optimum temperature
water, to soften down the testa so that the shoot can break out from the testa
and oxygen, for aerobic respiration
.
If these conditions are absent, the seed may be in the state of dormancy. where is won't germinate until it meets the suitable conduction.
after that, the enzyme will digest the nutrient inside the seed and provide amino acid, which is necessary to seed germination. and meanwhile the aerobic respiration provides energy, so that the plumlecan shoot out, and be the shoot of the plant.
and then until it grows leaves, it'll start to complete photosynthesis, instead of using the nutrients inside the cotelydon.
D) Long chains of amino acids used for building, repair, and maintenance
Proteins are made up of amino acids, and they are used to create substances (like hair, nails, etc.)
Hope this helps!!
Answer: Biotechnology is the area of biology that uses living processes, organisms or systems to manufacture products or technology intended to improve the quality of human life.

Answer:
B) a sequence of three nucleotides
Explanation:
A codon is the sequence of three nucleotides that decide that which particular amino acid would be incorporated in the polypeptide chain. Each codon code for a particular amino acid and responsible for the primary structure of proteins.
During translation the transfer RNA have the anticodon on its one side and amino acid bound to it on its other side. It adds the amino acids to growing polypeptide chain by binding to particular codon on messenger RNA.
Example; AUG is the starting codon for every protein and code for methionine in eukaryotes and anticodon for it is UAC.
