Topics Acceleration, Decomposers, Kidneys & Bladder, Proton, Stomach

Study Guide

Acceleration

Acceleration is the rate of change of velocity per unit of time. In physics, the delta symbol (\(\Delta\)) represents change so the formula for acceleration becomes \(\vec{a} = { \Delta \vec{v} \over t }\)

Decomposers

Decomposers (saprotrophs) are organisms such as bacteria and fungi that break down the organic matter in the dead bodies of plants and animals into simple nutrients.

Kidneys & Bladder

Chemical waste like excess water, minerals, and salt are filtered from the blood by the kidneys and secreted into the urine. Urine is transported from the kidneys to the bladder through ureters.

Proton

A proton is a subatomic particle found in the nucleus of an atom. It carries a positive electric charge.

Stomach

Food is mixed with gastric acid and pepsin in the stomach to help break down protein.
