Answer:
The correct answer is: a) osmosis.
Explanation:
- Osmosis can be defined as the physiological process by which molecules (in this case water) tend to move from a region where their concentration is high to a region where their concentration is low by the process of diffusion across a semi-permeable membrane.
- Active Transport can be defined as the physiological process in which molecules are forced to move from a region where their concentration is low to a region where their concentration is high across a semi-permeable membrane. This process requires the expenditure of energy and is usually mediated by carrier proteins or integral membrane proteins which span across the plasma membrane.
- Filtration can be defined as the physical process by which insoluble solute molecules are separated from the solvent molecules by the help of a porous filter paper which allows the solvent molecules to pass through it but restricts the insoluble solute molecules from passing through it.
- Diffusion can be defined as the physical process by which molecules tend to move from a region where its concentration is high to a region where its concentration is low. However, unlike osmosis, there is no semi-permeable membrane which separates the two regions.
Well in most ecosystems, all the energy in the food chain originally comes from the sun. Plants absorb carbon dioxide from the air and using energy from the sun, the plants turn it into glucose. Then the glucose is transformed into ATP inside the bodies of animals
D because it is the correct one
The answer to this question is the term ictal. Ictal is a term which means in the state of stroke, seizure, or headache. In seizure, the middle of this is what we called the ictal that can be seen through an electroencephalography or ecg.
