<span>Both photosystems have multi-protein complexes with pigments,
and an electron transport chain, in their thylakoid membranes reaction centers
that harvest energy from light photons and used for photosynthesis.

<span />
The difference
is that Photosystem II has a quinone-type reaction center <span>while that of photosystem I have
an iron-sulfur (Fe-S)-type. Additionally, in the electron chain reaction, photosystem
I pass the electron to ferredoxin, while Photosystem II contains plastoquinone,
which passes the energetic electron to cytochromes b6 and f.</span>
Yy x Yy yields 25%YY 50% Yy and 25% yy which is 1:2:1 (YY:Yy:yy)
Answer:
C.the fertile offspring of individuals that are well adapted to their environment will make up the greater proportions of the next generation.
H.individuals better suited to their environment are more likely to survive and reproduce.
Explanation:
The requirements for evolution by natural selection are;
C.the fertile offspring of individuals that are well adapted to their environment will make up the greater proportions of the next generation.
H.individuals better suited to their environment are more likely to survive and reproduce because
Natural selection refers to basic mechanism of evolution where by organisms develop traits or characters that will make them to adapt, survive and reproduce in their environments thereby transferring those traits or characters to their next generations.
It is survival and reproductive mechanism.
