Your shoe does not fit correctly. Blisters often mean that the shoe is rubbing places too much when you walk. If the shoe is too small, the shoe will be too tight and restrict your foot, in turn making your toes forced together and heels being rubbed. If the shoe is too big, your foot moves around too much in the shoe, making the shoe to cause blisters.
Answer:
Many people don't understand why or how other people become addicted to drugs. They may mistakenly think that those who use drugs lack moral principles or willpower and that they could stop their drug use simply by choosing to. In reality, drug addiction is a complex disease, and quitting usually takes more than good intentions or a strong will. Drugs change the brain in ways that make quitting hard, even for those who want to. Fortunately, researchers know more than ever about how drugs affect the brain and have found treatments that can help people recover from drug addiction and lead productive lives.
Store your medicines in a cool, dry place. For example, store it in your dresser drawer or a kitchen cabinet away from the stove, sink, and any hot appliances. You can also store medicine in a storage box, on a shelf, in a closet. If you are like most people, you probably store your medicine in a bathroom cabinet.
Answer:
a. osmosis
: Diffusion of water across a semi-permeable membrane.
b. diffusion
: Process that causes red dye to uniformly color a beaker of water red.
c. facilitated diffusion
: Type of passive transport where glucose is "helped" across the membrane.
d. phagocytosis
:
e. pinocytosis
: Process by which the cell brings water droplets into the cell.
f. hypertonic
: Describes a solution that is more concentrated than the inside of a cell.
g. hypotonic
: Describes a solution that is less concentrated than the inside of a cell.
h. isotonic
i. filtration
: Pressure gradient is the driving force for this type of passive transport.
j. exocytosis
: Process by which a cell eliminates waste.
k. equilibrium
: State in which all particles in solution are evenly spaced from one another.
l. active transport: Process that moves molecules from low to high concentrations.
Explanation:
Passive Transport:
- Cellular transport that occurs without expenditure of energy. Types include:
- Diffusion which is the movement of substances down the concentration gradient from high to low concentration across a semi-permeable membrane.
- Osmosis is the movement of water molecules from high water (low solute) to low water (high solute) concentration.
- Facilitated diffusion is the diffusion of substances across membranes via channel or membrane proteins.
Active Transport:
- Cellular transport that requires energy.
Type of Solutions:
- Hypertonic solutions are more concentrated than the cellular environment.
- Hypotonic solutions are less concentrated than the cellular environment.
- Isotonic solutions possess same concentration as cellular environment.
