Answer:
Photons
Explanation:
Photons are the only source of energy for photosynthesis. Photons are absorbed by chlorophyll molecules within Photosystems I and II (and antennae complexes), generating higher-energy ‘excited’ states of the photosystems which can carry out energetically costly chemical reactions.
Answer:
The correct answer is b) Food → Glycolysis → Krebs cycle → Electron transport chain.
Explanation:
When food enters the organism it goes through a lot of processes to become the beginning of glycolysis which produces pyruvate, which turns into acetyl CoA, which at the same time is the beginning material of Krebs cycle. The products of this cycle provide energy for the electron transport chain (NAD(H) and FAD(H)).
Sponges have specialized cells and an endoskeleton, but they lack tissues and body symmetry. ... They include jellyfish and corals, both of which have radial symmetry. All cnidarians have nematocysts, and many are bioluminescent. They may exist in medusa and/or polyp form.
