Heat Transfer

• Convection: Transfers heat through air and liquid. Creates a current. Warm air rises and cool air falls.

• Conduction: Transfers heat through touch. Heat moves from hot areas to cold areas.

• Radiation: Transfers heat through open space. You can feel the heat without touching it.

Multiple Choice

Which best descibes heat transfer due to convection?

• It occurs with direct contact

• It occurs only during the day.

• It occurs with movement of fluid.

• It occurs only when something is moving.

Multiple Choice

Which causes surface water in a lake to heat up during the hot summer?

• conduction

• convection

• evaporation

• radiation

Conductors:

• Allow heat to move easily between materials

• Good Conductors are: metals such as copper, brass, steel and aluminum

Insulators

• Insulators keep heat from moving easily between materials.

• Exampls of good insulators are: wood, plastic, rubber, ceramics

Multiple Choice

Which container used for cooking food would BEST conduct heat?

• a container made of foam

• a container made of glass

• a container made of metal

• a container made of plastic

Multiple Choice

Which BEST expains why a metal ice cream scoop works more efficiently than a plastic ice cream scoop when dipped in warm water prior to scooping the ice cream?

• The metal heats more quickly than the plastic.

• The plastic heats more quickly than the mtal.

• The metal insulates against the heat.

• The plastic conducts heat.

Multiple Choice

Why are pots used for cooking made of metal?

• Metal is an excellent conductor of heat.

• Metal makes the handle look attractive.

• Metal is a poor conductor of heat.

• Metal is natural and inexpensive.

Multiple Choice

Why is copper often used to line the bottom of cookware?

• Copper cools quickly.

• Copper is inexpensive.

• Copper is a good insulator.

• Copper is a good conductor.

Heredity

• In multicellular organisms parents transmit (pass) genetic traits to their offspring.

• Inherited traits are traits that parents pass to their offspring through genes. Examples include: eye color, hair color, height, shape of nose

• Aquired traits are traits that people learn or obtain over time. Examples incude: scars, ability to read, knowing not to touch a hot stove, riding a bike

• Environmental factors influence the acquired traits of an organism.

Multiple Choice

Which of the following BEST explains why children usually look more like their siblings (brothers and sisters) than their friends.

• The eat more of the same foods and drinks as their siblings.

• They spend more time together over the years with their siblings.

• They share many of the same genes from their parents with their siblings.

• They share more of the same environmental influences with their siblings.

Multiple Choice

A deer inherits some of its features from its parents. Other features come from its environment. Which feature would a deer MOST likely inherit from it's parents?

• a long scar

• brown eyes

• missing teeth

• a broken anter

Multiple Choice

By artificial selection, certain traits have been selected to be passed on to the offspring in certain tomato plants. Which traits have been strongly influenced by genetics in these tomato plants?

• length of the vines.

• depth of the plant roots

• directions the plant grows

• color and shape of the fruit

Multiple Choice

The following are inherited traits from humans EXCEPT?

• long hair

• blue eyes

• long eyelashes

• small dimples.

Multiple Choice

Which is an example of a learned behavior?

• a dog scratching an itch

• a fish breathing through gills

• a kitten having whiskers on its face

• a cheetah successfully hunting prey

Multiple Choice

William and Owen are brothers who have blond hair, green eyes and freckles. They both are skilled basketball players and play the guitar. Which two characterisics are most likely learned?

• eye color and hair color

• freckles and ability to play guitar

• eye color and ability to play basketball

• ability to play basketball and ability to play guitar

Unicellular organisms

• Have only one cell

• The single cell has to perform all the life functions

• Short lifespan

• Can reproduce asexually (make a clone of itself)

• Examples include: amoeba, Paramecium, protozoa

Multicellular Organisms

• Consist of more than one cell

• Differentiated cells perform specialized functions - cells work together to perform all of the life functions

• Cells have developed tranport systems to move the elements necessary for life around the body (example is oxygen)

• Specialized cells group together to form tissues, which group together to form organs, which group together to form organ systems, which group together to make up organisms.

Multiple Choice

Which is the order of cellular organisms from least to most complex in multicellular organisms?

• cell, tissue, organ, organ system, organism.

• tissue, cell, organ, organ system organism

• cell, organ, tissue, organ system, organism

• organism, organ, organ system, tissue, cell

Multiple Choice

How can a Paramecium carry out all of life's functions?

• by having specialized cells

• by being larger than most organisms

• by being smaller than most organisms

• by performing all processes in one cell

Multiple Choice

What is the difference between single-celled organisms and multicellular organisms ability to survive

• Multicellular organisms depend on other organisms for survival, while single celled organisms do not.

• Single-celled organisms depend on other organisms for survival while multicellular organisms do not.

• Single-celled organisms contain many specialized cells necessary for survival, while multicellular organisms do not.

• Multicellular organisms contain many specialized cells necessary for survival, while single-celled organisms can survice alone.

Multiple Choice

Which BEST explains why a human needs many cells to survive?

• Each individual cell is too small to function alone.

• Each cell joins with other cells to form one massive cell.

• Each cell works with other cells to perform all necessary life functions.

• Each cell absorbs a different gas from the environment, necessary for human survival.
