The correct answer to your question is the last one; how species change over time.
Hope that helps!
Errors can occur when the chromosomes segregate into the gametes during meiosis resulting in egg or sperm with too many or too few chromosomes. As a result, fertilised eggs and the ensuing embryos may have trisomy (an extra chromosome of a particular pair) in each cell or monosomy (one chromosome fewer in each cell).
This method is called Scientific Notation.
Answer:
they are the base of the food chain, they provide for all life above them.
Explanation:
Answer:
Option C is correct
Explanation:
Wavelength of the sound waves varies inversely with respect to frequency which means that if frequency increases wavelength will decrease and if frequency decreases wavelength increase.
Mathematically this relation can be represented as -

Where W represents the wavelength and f represents the frequency
When frequency is constant, wavelength exhibit direct proportionality relationship with speed.
