Frogs or toads... If neither I’m so sorry!
Good luck on your studies!
Answer:
D) because they separate, develop different traits therefore, they can no longer reproduce with each other.
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.
Answer:
30meter per second
Explanation:
Given that
Distance = 3000 meters
Time = 100seconds
Speed = distance /time
Substituting the values
Speed = 3000/100
Speed = 30meter per second
The average speed needed to cover the travelling will be 30meter per second.
Answer:
Virchow was a German scientist whose most important work was in the filed of cellular biology and pathology.His scientific experiments and examinations aimed to disprove the idea of spontaneous generation. This idea is based on an assumption that life can spontaneously appear out of non-living matter. After years of scientific work he concluded that only living cells can produce other cells, or that only life can produce life.Therefore, if it was somehow proven that cells can be generated from non-living matter, that would disprove his findings.
