There's similarities between green algae and plants .both plants and green algae contain the same form of chlorophyll.
but land plant are multicellular and autotrophic
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.
<span>This is an ascribed status. These are the characteristics and parts of one's being that are attained at birth or given to them later in life without their control. Age, sex, race, ethnicity: all of these characteristics are largely out of a person's control and are ascribed to them from the time they are born.</span>
