What is photo synthesis ?​

is a process by which phototrophs convert light energy into chemical energy.

The word “photosynthesis” is derived from the Greek words "phos" (which means “”) and "σύνθ-εóîς" (which means “ .”) And so it means “combining together with the help of light.”

The process of photosynthesis occurs in green plants (the primary producers in a food chain) and a few other autotrophic organisms such as cyanobacteria, purple bacteria and green sulfur bacteria.

Following is the photosynthesis formula:

6 CO2 + 6 H2O —> C6 H12 O6 () + 6 O2 ().

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
