Answer:
Anemometer
Explanation:
It should be understood that the anemometer is different to wind vane in both structure and function.
This is because, anemometer is an instrument that is used to measure the speed of the wind, while the wind vane is used to measure the direction of the wind.
Therefore, in this case, the anemometer is going to be the instrument to measure the speed of the wind above the ocean waters.
Answer:
D
Explanation:
proteins make up every thing
Cyanobacteria are oxygenic photosynthetic bacteria. They harvest the sun's energy, absorb carbon dioxide, and emit oxygen. Like plants and algae, cyanobacteria contain chlorophyll and convert carbon dioxide to sugar through carbon fixation. Unlike eukaryotic plants and algae, cyanobacteria are prokaryotic organisms.
Carbon dioxide is what humans exhale, giving trees carbon dioxide will produce oxygen
