Answer:
prezygotic ... behavioral isolation
Explanation:
Prezygotic barrier is a reproductive barrier that occurs when fertilization is prevented from occurring as a result of isolation leading to prevention of copulation, and as such there is no fusion of gametes for fertilization to take place, and eventually formation of zygote. Zygote is not formed as fertilization does not take place.
Behavioral isolation is a prezygotic reproductive barrier that prevents two or more different species to copulate together in order for fertilization to take place due to differences in behavior that is unique to each species. One of such behaviors is mating calls.
As a result of the differences in mating calls which is unique to each species of frogs mentioned in the question, only members of each species get attracted to themselves and mate with their members, thereby making it almost impossible for the three different species of frogs to mate together.
Answer:
Chlorophyll molecules donate electrons to an electron acceptor in the reaction center.
Explanation:
Light reaction of photosynthesis takes place in the reaction centre. Light reaction may comprises of several proteins such as pheophytin, chlorophyll and quinones which act as light absorbing molecules.
The light reaction is the core of photosynthesis that produces ATP and NADPH to carry out the dark reaction for the production of high energy carbon molecules. During light reaction light photons are captured by photosystems such as photosystem I and II of chlorophyll in green plants. This photon cause the excitation of electron that flows through the electron transport chain from higher potential to lower potential and energy released by it is utilized for creating the gradient potential of H+ ions across the membrane. This gradient potential difference of H+ ions is used for the production of ATP through ATP synthase complex.
So chlorophyll molecules donate electrons to electron acceptors through the excitation of electrons from light photons in the reaction center.
Explanation:
I think the answer is NEAs
Necleuic acids. Remember, this has to do with the brain.
