Explanation:
Carrier proteins are proteins that carry substances from one side of a biological membrane to the other.
Answer:
nature preserve to save the population since thats where they breed
Answer:
3) away from the area where it is more concentrated
Explanation:
A substance that moves across a cell membrane without using the cell's energy tends to move away from the area where it is more concentrated.
It is known as passive transport.
It is the process in which substance without using the cellular energy tend to move down the concentration gradient.
It is also known as simple diffusion.
All other options are incorrect because,
In case of active transport substance move against the concentration gradient i.e to wards the area of higher concentration.
This process require energy.
Answer: amplitude would help measure height
low f, constant speed, long wavelength
speed = frequency x wavelength
Explanation: constant speed, low frequency
frequency = speed/wavelength; at constant speed f proportional to 1/wavelength, so low f __> long wavelength
speed = freq*wavelegth
