Answer:There may be many possible alleles for any gene, but a diploid cell or animal contains only two alleles of each gene or two copies of a single allele; a haploid gamete contains one copy of each gene, so only one allele.

Answer: True,
Small amounts of hormones have large effects on an organism because the signals are amplified between glands and tissues due to the second messenger systems.
explanation:
Second messemgers are the intracellular molecules which are activated by the extracellular molecules. Second messengers intracellulary triggers physiological changes such as proliferation differentiation migration etc.
When hormones are released they bind to specific receptors such as G-coupled recptors,tyrosine recpetor which when activated further activates second messengers such as cAMP and STAT respectively.
These second messengers amplify the hormone secretion and production by phosphorylation and increasing transcription.
Hence this is true that second messnegers amplify the hormones and their physiological results.
