tia_tia [17]

Answer:

G-protein-linked receptor

Explanation:

Epinephrine acts via G-protein-linked receptors. The heterotrimeric G proteins located within the cell are activated by G protein-coupled receptors that span the cell membrane. Signaling molecules bind to a domain on the GPCR located outside the cell, and an intracellular GPCR domain then in turn activates a particular G protein.

vitfil [10]

Answer:

The correct answer is -

Decrease plant growth - decrease sunlight, decrease CO2, decrease H2O

NO effect - increase O2, decrease O2, increase C6H12O6, decrease C6H12O6

Increase plant growth - increase CO2, increase sunlight, increase H2O

Explanation:

Decrease in exposure of sunlight to the plant or less intense light will affect the production of oxygen and glucose negatively which affect the growth of the plant. Decrease CO2 will be affect the growth of the plant similarly as light and water molecules which is decreased in plant growth.

Increase in the in production of the products which are 02, glucose, will have no effect in plant growth though increase in the carbon dioxide, water, and sunlight will positively affect plant growth.

Thus, the correct answer is - decrease plant growth - decrease sunlight, decrease CO2, decrease H2O

no effect - increase O2, decrease O2, increase C6H12O6, decrease C6H12O6

increase plant growth - increase CO2, increase sunlight, increase H2O

The effect of such toxic chemicals to the body is that they stimulate uncontrolled cell division. Uncontrolled cell division or cells proliferation may lead to cancer. The unchecked cell growth results to mutations in genes that can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death.
