Homeostasis – Homeostasis is the ability to maintain a relatively stable internal state that persists despite changes in the world outside
<span>Early pre-cambrian period the atmosphere consisted only of nitrogen and carbon dioxide without oxygen.
<span>A
Prokaryotic cell does not contain a nucleus. It only contains one
chromosome and is a single-celled organism. It was the only form of life
on earth for millions of years. Examples of a Prokaryotic cell are the
different types of bacteria present today.
</span><span>Autotrophs
obtain energy by the process of photosynthesis. Any living organism
need energy to survive and autotrophs are no different. Two types of
autotrophs are present and they are Photoautotrophs and Chemoautotrophs.
The Photoautotrophs rely on the energy produced during the process of
photosynthesis and the Chemoautotrophs get their energy from most of the
inorganic substances. Phtoautotrophs actually get their energy from the
sunlight and then convert it into reusable form. In case of
Chemoautotrophs ammonia is an important source of energy for them.</span></span>

poly is the prefix for many
Answer:
A concentration gradient will be developed.
Explanation:
1. When the oxygen concentration is more outside a cell, then by the process of diffusion the oxygen will pass into the cell.
2. Diffusion can be described as a process in which molecules move from a higher concentration to a lower concentration i.e. along a concentration gradient. Hence, this process does not require energy.
3. When the oxygen concentration will be more in a cell then again through diffusion the oxygen will move out of the cell.
