Answer:
For an individual who is heterozygous for two genes, Aa and Bb, what does independent assortment predict? Offspring inheriting the recessive allele
of the first gene will also inherit the dominant
Explanation:
Aa x Bb= AB, Ab, aB and ab
so the first gene will also inherit the dominant gene
The correct answer is A, a good hypothesis does not have to be complex
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.
Answer:
A. They have the same number of atoms
