In cell biology, cytokinesis results in two separate:
chromosomes |
|
nuclei |
|
chromatids |
|
cells |
During cell division, the cytokinesis phase occurs when cytoplasm and cell membranes complete their separation resulting in two separate cells.
Scalar quantities are fully described by which of the following?
a direction only |
|
a magnitude and a direction |
|
a magnitude only |
|
a magnitude and a polarity |
Velocity and displacement are vector quantities which means each is fully described by both a magnitude and a direction. In contrast, scalar quantities are quantities that are fully described by a magnitude only. A variable indicating a vector quantity will often be shown with an arrow symbol: \(\vec{v}\)
Minerals, vitamins, and fiber are:
proteins |
|
macronutrients |
|
carbohydrates |
|
micronutrients |
Minterals, vitamins, and fiber are micronutrients while proteins, carbohydrates, and fats are macronutrients.
Which of the following is the formula for power?
\(P = \vec{w}t\) |
|
\(P = {\vec{w} \over t}\) |
|
\(P = {w \over t}\) |
|
\(P = w t\) |
Power is the rate at which work is performed or work per unit time: \(P = {w \over t}\) and is measured in watts (W).
The large intestine does which of the following?
processes the physical waste produced by digestion |
|
breaks down starches |
|
breaks down fats |
|
breaks down proteins |
The large intestine (colon) follows the small intestine and processes the physical waste produced by digestion, absorbing water and minerials that remain back into the body. Solid waste is then stored in the rectum while liquid waste is stored in the bladder.
