Explanation:
Cell membranes are barriers which protect and regulate the movement of substances in and out of the cells. It is a semi-permeable and selective structure.
In the passive transport system, substances move along a concentration gradient and it doesn't require energy. The examples of passive transports include; simple diffusion which transports carbon dioxide and oxygen, osmosis and facilitated diffusion which transports charged molecules like ions, sucrose etc.
In active transport, substances move against the concentration gradient. This requires energy. The two main types are: primary active transport, which uses direct metabolic energy e.g Na+/K+ pump, and the secondary active transport system which couples the transported molecules with another molecule moving along the gradient, example the Na+/glucose transporter.
These are fun facts about greenhouse gases that...
1.) The three greenhouse gases that are of most concern are Carbon Dioxide (CO2), Nitrous Oxide (N2O), and Methane (CH4).
2.) Greenhouse gases trap heat in the atmosphere warming the Earth’s temperature above freezing. This is known as the Greenhouse effect.
3.) Greenhouse gases are naturally produced; however humans produce additional amounts of certain greenhouse gases.

Answer:
think about it as a wave
Explanation:
The first steps in this sensory process are the stimulation of light receptors in the eyes, conversion of the light stimuli or images into signals, and transmission of electrical signals containing the vision information from each eye to the brain through the optic nerves.
