Convert 0C° to F°.
32 |
|
16 |
|
-32 |
|
0 |
To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(0) + 32\)
\(F° = 0 + 32 = 32\)
Which of these is important for the body's maintenance, growth, and repair?
carbohydrates |
|
fats |
|
fiber |
|
protein |
Found in both animal sources (meat, fish, eggs, cheese) and vegetables (beans, nuts, some grains), proteins are important for the body's maintenance, growth, and repair.
Acceleration is the rate of change of velocity per unit of time. Which of these is the formula for acceleration?
\(\vec{a} = { \vec{v} \over t }\) |
|
\(\vec{a} = { t \over \Delta \vec{v} }\) |
|
\(\vec{a} = \Delta \vec{v} t \) |
|
\(\vec{a} = { \Delta \vec{v} \over t }\) |
Acceleration is the rate of change of velocity per unit of time. In physics, the delta symbol (\(\Delta\)) represents change so the formula for acceleration becomes \(\vec{a} = { \Delta \vec{v} \over t }\)
Bronchioles, alveolus, and capillaries are vital parts of which bodily system?
nervous |
|
circulation |
|
digestion |
|
respiration |
The trachea branches into the left and right bronchi which each lead to a lung where the bronchi subdivide into smaller tubes called bronchioles. Each bronchiole ends in a small sac called an alveolus which allows oxygen from the air to enter the bloodstream via tiny blood vessels called capillaries.
DNA is encoded through a combination of which of the following?
nucleotides |
|
helix |
|
genes |
|
gametes |
Deoxyribonucleic acid (DNA) is the molecule that contains genetic information. DNA is encoded through a combination of nucleotides that bind together in a specific double helix pattern.
