Answer:
I took this in middle school option 3
Explanation:
Answer:
When frequency increases more wave crests pass a fixed point each second. That means the wavelength shortens. So, as frequency increases, wavelength decreases. The opposite is also true— as frequency decreases, wavelength increases.
Explanation:
The number of complete wavelengths in a given unit of time is called frequency. As a wavelength increases in size, its frequency and energy decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
Answer:
None of the options provided is correct but some are close
Explanation:
One of the ways in which a cell maintain homeostasis is by regulating what goes in and out of the cell through the cell membrane (which is a semi-permeable barrier). The amount of water is highly regulated by the cell in this case so as to regulate osmosis (movement of water molecules from a region of higher concentration to a region of lower concentration). Other substances regulated are oxygen and carbon dioxide.
NOTE: The cell <u>does not create water molecules neither does it use carbon dioxide to maintain homeostasis</u>, it rather regulates these two compounds.
