The <u>radiant </u>energy of the sun is converted into <u>chemical </u>energy by the plants. Answer is C and A.
Answer:
F=dominant, 6 fingers
f= reccessive, 5 fingers
Ff= 6 fingers( contains dominant gene)
if you combine Ff and Ff you get:
25% FF (6 fingers)
50% Ff (6 fingers)
25% ff ((5 fingers)
so only 25% will have 5 fingers (normal)
Answer2:
Dominant=normal hearing
Recessive= deafness
If one parent is RR and the other Rr, the offspring will be:
50% RR
50% Rr
so all the offspring will have normal hearing, and there is 0% of deafness.
