The right answer is photosystem I
And the three protein complexes are : plastoquinone, cytochrome b6f complex, plastocyanin.
In plants, photophosphorylation occurs in the membrane of thylakoids, within chloroplasts:
H2O ==> photosystem II (which contains P680) ==> plastoquinone ==> cytochrome b6f complex ==> plastocyanin → photosystem I (which contains P700) ==> ferredoxin ==> ferredoxin-NADP + reductase ==> NADP +
As newer rock layers form, they overlap with the ones with the pre-existing ones. Therefore, when looking for older rock layers, we would look for the ones that are deeper beneath the surface of the earth. On the other hand, newer rock layers are found at the top. This is also observed in the fact that oil rigs dig very deep into the ground to access the layers that are millions of years old.
B. Two disaccharides bonded together
You must pack food that has high concentrations of fat and protein. Food like granola bars and canned meat are a good source of energy and heat. This is because the body breaks this food down easily converting it into usable energy. Though some people would suggest that you pack food that are high in carbohydrates, fats and proteins are long-term sources of energy that you would need for your hiking trip.
Answer:
A
Explanation:
Because there are two DNA strands in the DNA molecule and they both rotate around each other in a helix formation. So two helixes = double helix.
