Answer:
True!
Explanation:
Sometimes an entire ocean closes as tectonic plates converge, causing blocks of thick continental crust to collide. A collision mountain range forms as the crust is compressed, crumpled, and thickened even more. The effect is like a swimmer putting a beach ball under his or her belly—the swimmer will rise up considerably out of the water. A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction.
The natural succession of a small farm pond will tend to make the pond more likely to freeze solid in winter time,the nature of things helps them to merge more quickly and adapt to their environment.
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.
