SCIENCE

Which mode of heat transfer involves direct contact?

Conduction

The transfer of heat through the physical movement of fluids (liquids or gases)

Convection

The transfer of heat through empty space via electromagnetic waves (such as infrared).

Radiation

A non-contact method of heating that uses electromagnetic fields to induce electrical currents (eddy currents) directly inside a conductive material

Induction

These properties measure the "extent" or size of a system. If you increase the amount of the substance, they scale up accordingly (e.g., they are additive).

Extensive Properties

These properties are inherent to the material itself and are often used to identify an unknown substance. If you divide the sample in half, the value of an intensive property stays exactly the same.

Which phase of mitosis separates sister chromatids?

Anaphase

Which process absorbs heat from the surroundings?

Endothermic

Which statement best describes a virus?

A non-living particle that requires a host cell to reproduce

Which is an ethical issue in genetic technology?

Designer babies

Which best describes a biotic relationship?

Interaction between two or more living organisms

Relationship where one organism kills and eats another organism

Predation

Happens when organisms compete for limited resources such as food, water, or territory.

Competition

Is a symbiotic relationship where a an organism lives on or inside a host and causes harm.

Parasitism

A relationship where one organism benefits while the other organism is not affected.

Commensalism

A symbiotic relationship where both organisms benefit. Bees collect nectar from flowers for food, but they also transfer pollen between flowers, helping them reproduce.

Mutualism
