Explanation:
Yes, I think communities should use these green energies because not only does it keep the atmosphere safer and cleaner, it could help tremendously in the case that we run out of fossil fuels before we can find an alternative. Yes there are environmental risks, such as birds dying from wind turbines, but the lack of electricity might be more severe.
Answer:
The correct answer is- facilitated diffusion
Explanation:
In facilitated diffusion molecules(solutes) are moved from area having a high concentration of solute towards the area having low solute concentration through a semipermeable membrane with the help of specific proteins is called facilitated diffusion.
As molecules move along the concentration gradients so no energy consumption is required in facilitated diffusion. Transport proteins like channel proteins are used to transport the molecules across the cell.
The rate of transport is higher in facilitated diffusion than simple diffusion. Polar and charged molecules can be diffused by facilitated diffusion.
Answer:
The correct answer is (B) A larger area of the sensory cortex is associated with our lips.
Explanation:
All the sensory inputs that come from the body is received by the somatosensory cortex. Neurons are responsible for sensing the perception of touch, heat, pains, etc on any body part and pass the information to the somatosensory cortex where the information gets processed.
Our lips contain many nerve endings and nerves which makes it very sensitive towards touch, warm, and cold. So due to the large number of nerve in lips it is considered as an erogenous zone which states that this area is very highly sensitive. So the correct answer is B.
