Reproductive haploids are also known as:

62% Answer Correctly

ovum

sperm

diploids

gametes


Solution

Reproductive (haploid) cells known as gametes have half as many (23) pairs of chromosomes as normal (diploid) cells. When the male gamete (sperm) combines with the female gamete (ovum) through meiosis to form a zygote, each gamete supplies half the chromosomes needed to form the normal diploid cells.


2

Which of the following is the correct order for types of radiation from lowest to highest frequency?

63% Answer Correctly

microwaves → radio waves → visible light

infrared waves → microwaves → ultraviolet light

radio waves → visible light → gamma rays

visible light → ultraviolet light → radio waves


Solution

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.

50°F is how many °C?

72% Answer Correctly

10

-10


Solution

The formula to convert from F° to C° is:

\(C° = {5 \over 9} (F° - 32)\)

plugging in our values gives:

\(C° = {5 \over 9} (50 - 32)\)

\(C° = {5 \over 9} (18)\)

\(C° = {90 \over 9}\)

\(C° = 10\)

In the foood chain, producers serve as a food source for other organisms. Typical producers are plants that can make their own food through photosynthesis and certain bacteria that are capable of converting inorganic substances into food through:

47% Answer Correctly

autotrophs

photosynthesis

chemosynthesis

decomposition


Solution

Producers (autotrophs) serve as a food source for other organisms. Typical producers are plants that can make their own food through photosynthesis and certain bacteria that are capable of converting inorganic substances into food through chemosynthesis
