In Activity A, you explored photosynthesis in a pond. The dissolved oxygen in a pond is produced by pond plants and algae (small, plant-like organisms) in a process called
photosynthesis.
What is the source of energy that is present during the time that photosynthesis takes
place?

Photons

Explanation:

Photons are the only source of energy for photosynthesis. Photons are absorbed by chlorophyll molecules within Photosystems I and II (and antennae complexes), generating higher-energy ‘excited’ states of the photosystems which can carry out energetically costly chemical reactions.

i am thinking the sun is the answer because the sun is usually the main source of energy that is included in photosynthesis

they absorb it i think

not sure

you

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
