The side of the chair facing the fireplace gets warm because of_______________. 3. A certain type of decorative lamp contains colored liquids. These liquids form globs that break off and rise to the top of the liquid. The globs rise due to _______________.

Answers

Answer 1
Answer:

Answer:

1) Conduction.

Heat transfers to a spoon as the heat energy is passed from the coffee to the spoon through conduction.

2) Radiation

The heat on the glass surface gets radiated into the chair which causes the chair to warm up.

3) Convection

The globs are hot and less dense, which rises to the top whereas the cold globs are more dense which causes it to settle down.
Answer 2
Answer:

Final answer:

1. Hot coffee warms the spoon through conduction,  

2. a chair warms through radiation from the fireplace,

3. decorative lamp globs rise through convection.

A flatworm obtains oxygen needed for cellular respiration through simple diffusion. A human obtains oxygen by breathing it in from the air and into the lungs. Which system is the flatworm missing?

Answers

Flatworms are high-flattened organisms dependent on direct diffusion as means of oxygen intake and release of carbon. This small organisms lack "fully evolved respiratory tissues such as lungs or gills and complex circulatory system as means to transport oxygen through out the body. 
>Direct diffusion of gases through the outer membranes can be used by organisms such as flatworms as a means of respiration due to their small size and simplicity.

Echolocation is an adaptation bats use to _______.a.
hunt insects in flight
b.
locate flowering plants
c.
find warm places for hibernation
d.
all of the above

Answers

The correct answer is option D

Echolocation can be defined as the technique by which the bats use sound to locate the places or objects. It is the active use of sonar to locate the insects for hunting in flight during the night time.

Bats also use this technique to locate the places needed for hibernation during the time they are not active and also for locating the flowering plants.
The right answer for the question that is being asked and shown above is that: "all of the above." Echolocation is an adaptation bats use to hunt insects in flight; locate flowering plants; find warm places for hibernation
