In cell biology, cytokinesis results in two separate:
nuclei |
|
chromatids |
|
cells |
|
chromosomes |
During cell division, the cytokinesis phase occurs when cytoplasm and cell membranes complete their separation resulting in two separate cells.
50°F is how many °C?
10 |
|
122 |
|
-10 |
|
58 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (50 - 32)\)
\(C° = {5 \over 9} (18)\)
\(C° = {90 \over 9}\)
\(C° = 10\)
The angle of reflection is equal to which the following?
angle of incidence |
|
90° |
|
refractive index |
|
focal point |
The law of reflection specifies how waves, including light waves, bounce off of surfaces. Specifically, the angle of incidence of the approaching wave is equal to the angle of reflection of the reflected wave as measured from a line perpendicular (90°) to the surface.
Which of these is not a type of fat?
saturated |
|
cholesterol |
|
monounsaturated |
|
polyunsaturated |
Fats come in three types, saturated (meats, shellfish, eggs, milk), monounsaturated (olives, almonds, avocados), and polyunsaturated (vegetable oils).
pH is a scale that measures of how basic or acidic a solution is. A solution with a pH of 9 is:
water |
|
alkaline |
|
acidic |
|
neutral |
An acid is a substance that gives up positively charged hydrogen ions (H+) when dissolved in water. A base (alkaline) gives up negatively charged hydroxide ions (OH-) when dissolved in water. pH is a scale that measures of how basic or acidic a solution is. Numbered from 0 to 14, solutions with a pH of 7 are neutral, less than 7 are acidic, more than 7 are alkaline.
