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.
Answer: B C D
Explanation: it’s the food chain, and predators eat prey! In this case the smaller one!!!
The Taxonomic rank ( from the largest to the smallest) goes something like this:
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
So, the largest from your given options is phylum.
Hope this answered your question
B) The Earth's crust is pulled apart creating deep folds and then pushed together generating steep scarps to create fault-block mountains
Answer:
Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.
