__________ is caused by a lack of Vitamin C.
scurvy |
|
diabetes |
|
anemia |
|
shingles |
Scurvy is a difficiency disease caused by a lack of Vitamin C in the diet.
212°F is how many °C?
100 |
|
-100 |
|
\(135 {5 \over 9}\) |
|
0 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (212 - 32)\)
\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)
\(C° = {900 \over 9}\)
\(C° = 100\)
The most diverse kindgom of life is which of the following?
fungi |
|
animals |
|
protists |
|
plants |
Below domain, life is classified into six kingdoms: plants, animals, archaebacteria, eubacteria, and fungi. The last kingdom, protists, include all microscopic organisms that are not bacteria, animals, plants or fungi. (Archaebacteria and eubacteria are sometimes combined into a single kingdom, monera.)
In which type of compound are electrons shared between atoms?
chemical |
|
ionic |
|
covalent |
|
molecular |
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.
Which of the following is the correct order for types of radiation from lowest to highest frequency?
visible light → ultraviolet light → radio waves |
|
infrared waves → microwaves → ultraviolet light |
|
radio waves → visible light → gamma rays |
|
microwaves → radio waves → visible light |
The electromagnetic spectrum covers all possible wavelengths and frequencies of radiation. From lowest frequency (longest wavelength) to highest frequency (shortest wavelength) radiation: radio waves → microwaves → infrared waves → visible light → ultraviolet light → X-rays → gamma rays.
