In which situation does the biosphere or hydrosphere cause a chemical change to the atmosphere? a. density currents in the ocean transfer heat that warms the atmosphere. b. photosynthesis by oceanic algae removes carbon dioxide from the atmosphere. c. evaporation from the surface of the ocean cools the lower atmosphere. d. transpiration from coastal ocean plants adds water vapor to the atmosphere.

Option B, Photosynthesis by oceanic algae removes carbon dioxide from the atmosphere

Explanation:

All the three processes i.e heating, evaporation and transpiration as mentioned in option A, C and D respectively are form of physical transformation where a substance change its form . However, in case of photosynthesis the carbon dioxide gas taken by plants  undergo chemical reaction with water in presence of sunlight to produce oxygen and energy.

Thus, option B is represents a situation where the biosphere or hydrosphere cause a chemical change to the atmosphere

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

2. how does an enzyme inhibitor work?

separate your answers so i dont get confused : )
