Energy from the sun heat and chemicals
Wing’s of butterfly’s are unique
It’s ability to change its form.
In his experiment mendel first crossed tall and short peas plant and noticed that the F1 plants were all tall. in the second experiment he crossed the the F1 plants and noticed that short plants reappeared in the rate of 25% in F2 generation. in his third experiment he crossed he crossed F2 plants and noticed that when he crossed some tall plants with the shot plants the F3 generation contained short plant in frequency of 50%. after this observations mendel concluded that there were genes that could be only expressed in homozygous state but not in heterozygous state. these genes were later referred to as recessive alleles wheres the genes that prevented the expression of recessive genes were later referred to as dominant genes.
Receptor specificity Physical energy such as light, sound,
and heat is detected by specialized receptor cells in the sense
organs—eyes, ears, skin, nose, and tongue. When the action potential that
relays information about the stimulus through the nervous system to the brain. Sensory
receptors take in information from the environment, creating local electrical
currents; These currents are graded.
