Answer:
Dispersion of white light by a prism
Explanation:
When white light is passed through a prism, the white light separates into its component wavelengths which are:
Red
Orange
Yellow
Green
Blue
Indigo
Violet
Together, all of these wavelengths constitute the spectrum of white light.
Hence, the dispersion of white light shows that each color of visible light has a specific wavelength.
Mutations are the source of all new alleles. An allele is a variant form of a gene. Variations in alleles lead to variations in organisms. Positive mutations give an organism a better chance of survival. It means that the mutation may be passed on to the offspring. Negative mutations may lead to an early death.<span> Therefore, changes in alleles from one generation to another form the basis of evolution.</span>
Two main factors that affect enzyme activities are temperature and pH value.
Every type of enzymes has their own optimum temperature and pH, where they work the fastest at.
for temperature, if the temperature is too low for the enzyme, they may become inactive, they work slow. Give them their suitable temperature they'll work fast again.
However, if the temperature is too high, the enzyme would be denatured. You cannot use them again.
Denatured enzymes means the enzymes already changes shape of the active site and can no longer bind into substrates and therefore no longer works, no matter if you provide the suitable environment again.
For pH, the concept is same, unless if the pH value is too extreme than the optimum pH, the enzyme will be denatured instead of being inactive.
Yay so happyyyyyyyyyyyyy for youuu
