What is the prefix "nano-" used to describe?

What can you conclude from the fact that nanotechnology can change a substance's physical properties?

Nanobots might be able to differentiate between cancerous and non-cancerous cells. What does this mean?

In the sentence, "One liability of nanotechnology is its ability to create weapons," what does "liability" mean?

Sunscreen combines which two types of active ingredients?

Often written as λ. It is the distance between identical successive waves. Units of length are m, μm, nm, etc.

Often written as Greek letter ν. It is the number of waves that pass through a particular point in one second. Units are cycles per second (abbreviated as Hertz, or Hz).

It is the vertical distance from the midline of a wave to the peak or trough. Units will vary.

Electromagnetic (EM) radiation contains which two types of fields (HINT: look at the word itself)?

What type of light is responsible for sunburns in human skin, as well as skin cancers and cataracts?

True or False: Shorter wavelengths are associated with higher energy.

Which type of ultraviolet radiation is totally absorbed by the Earth’s atmosphere?

What is the best protection against solar overexposure?

A liposome is comprised of a lipid bilayer which encloses an aqueous core. What does the prefix bi mean in the context above?

A __________ is a molecule with a hydrophilic phosphate head and a hydrophobic lipid tail, and is also that which the lipid bilayer of a liposome is composed of.

A(n) __________ is a minute spherical sac of phospholipid molecules enclosing a water droplet, especially as formed artificially to carry drugs or other substances into the cells and tissues.

A liposome is comprised of a lipid bilayer which encloses an aqueous core. What does the word aqueous mean in the context above?

A(n) __________ is a molecule that binds to another (usually larger) molecule. These molecules can be part of a "lock and key" system within cells that allows them to be selectively permeable (only allowing certain molecules in or out).

If a substance is able to be dissolved, especially in water, it is said to be __________.

What is the lotus effect?

In certain plants, water adheres so loosely to the leaf that the tiniest movement causes the beads of water to roll smoothly off, taking any dirt, debris, or other particles with them. This makes the leaves ____________.

__________ is the effect the BODY has on the DRUGS. It includes absorption, distribution, metabolism and excretion of drugs.

__________ is the effect that DRUGS have on the BODY. It involves receptor binding (ligands), post-receptor effects, and chemical interactions.
