To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(5) + 32\)
\(F° = {45 \over 5} + 32\)
\(F° = 9 + 32 = 41\)
Traits represented by genes may be which of the following?
recessive |
|
all of these |
|
expressed |
|
dominant |
The traits represented by genes are inherited independently of each other (one from the male and one from the female gamete) and a trait can be dominant or recessive. A dominant trait will be expressed when paired with a recessive trait while two copies of a recessive trait (one from each parent) must be present for the recessive trait to be expressed.
Plant cells may generate energy through which of the following?
aerobic respiration |
|
all of these |
|
anaerobic respiration |
|
photosynthesis |
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.
What part of the brain is responsible for for balance, movement, and muscle coordination?
brainstem |
|
cerebellum |
|
medulla |
|
cerebrum |
The cerebellum is a large cluster of nerves at the base of the brain that's responsible for balance, movement, and muscle coordination.
A compound is a substance containing two or more different chemical elements bound together by what kind of bond?
molecular |
|
chemical |
|
covalent |
|
ionic |
A compound is a substance containing two or more different chemical elements bound together by a chemical bond. In covalent compounds, electrons are shared between atoms. In ionic compounds, one atom borrows an electron from another atom resulting in two ions (electrically charged atoms) of opposite polarities that then become bonded electrostatically.
