Answer:
Mice and rats make up approximately 95% of all laboratory animals, with mice the most commonly used animal in biomedical research.
<h2>Active & Passive transport</h2>
Explanation:
- Active transport is where a chemical reaction using ATP moves things in/out of the cell through transport proteins within the cell wall. It uses a concentration gradient to trigger the reaction (it goes against the concentration gradient in active transport)
- Molecules move against a concentration gradient ( low concentration ―→ high concentration)
- Cellular energy (ATP) is required
- Passive transport also uses a concentration gradient by diffusion (hydrophobic or very small polar molecules) and facilitated diffusion via carrier proteins and channels
- Molecules move along the concentration gradient (high concentration ―→ low concentration)
- No cellular energy is required
Answer:
D
Explanation:
Diffusion and osmosis are both passive forms of transport because there is no energy need to transport something such as water from an area of high pressure, to an area of low pressure.
