Answer: Energy
Explanation:
If there is no chemical bonds in the substance or the bonds in the substances are so strong so there would be no energy released.
This is because there is a need of energy when any bond is formed and energy is released when bonds are broken down.
Energy is stored in the bonds which is released when bonds are broken down.
There would be no energy available for various processes and no movement of energy will take place.
Answer:
Water volume remains the same.
Explanation:
Ice formation is a phase change from liquid to solid. The ice is less dense so its volume gets larger. Warm it up, melt the ice and it will return to the same volume it had as a liquid.
The only logical answer would be C. Unicellular, but the answers seem to be all wrong.
Answer:
Photosynthetic reaction center differ from the chlorophyll molecules in the antenna complex by the presence and absence of core pigment and accessory pigment.
Explanation:
Photosynthetic reaction center contain core pigment known as chlorophyll A which can aborb wavelength of sunlight not more than 700 nm in case of Photosystem 1 and the core chlorophyll pigment of Photosystem 2 absorb light having wavelength of 680nm or less than that.
Antenna complex or light harvesting complex such as chlorophyll b ,Carotenoid,Xanthophyll absorb light energy from sunlight and transfer that light energy to photosynthetic reaction center by resonance energy transfer so that the photosynthetic reaction center uses the same(light energy) in form of chemical energy to out the further reactions of photosynthesis.
The embryo, endosperm and seed coat.
