1

50°F is how many °C?

72% Answer Correctly

-10

58

122

10


Solution

The formula to convert from F° to C° is:

\(C° = {5 \over 9} (F° - 32)\)

plugging in our values gives:

\(C° = {5 \over 9} (50 - 32)\)

\(C° = {5 \over 9} (18)\)

\(C° = {90 \over 9}\)

\(C° = 10\)


2

58% Answer Correctly

peripheral

autonomic

central

3

Plant cells may generate energy through which of the following?

73% Answer Correctly

aerobic respiration

anaerobic respiration

all of these

photosynthesis


Solution

Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.


4

The transfer of heat by the circulation or movement of the heated parts of a liquid or gas is called:

61% Answer Correctly

convection

diffusion

conduction

radiation


Solution

Convection is the transfer of heat by the circulation or movement of the heated parts of a liquid or gas. Examples of heat transfer by convection include water coming to a boil on a stove, ice melting, and steam from a cup of coffee. 


5

A __________ is the smallest multi-atom particle of an element or compound that can exist and still retain the characteristics of the element or compound. 

72% Answer Correctly

isotope

neutron

ion

molecule


Solution

A molecule is the smallest multi-atom particle of an element or compound that can exist and still retain the characteristics of the element or compound. The molecules of elements consist of two or more similar atoms, the molecules of compounds consist of two or more different atoms.
