The ovum and oviduct are part of which bodily system?
reproductive |
|
circulatory |
|
nervous |
|
digestive |
Approximately every 28 days during female ovulation an egg (ovum) is released from one of the ovaries and travels through the oviduct (fallopian tube) and into the uterus. At the same time, the endometrial lining of the uterus becomes prepared for implantation.
The __________ nervous system controls voluntary actions.
central |
|
somatic |
|
autonomic |
|
peripheral |
Part of the peripheral nervous system, the somatic nervous system is made up of nerve fibers that send sensory information to the central nervous system and control voluntary actions.

absolute zero |
|
-273°C |
Absolute zero is the coldest possible temperature in the universe. In the Kelvin scale, absolute zero is 0K and in the Celsius scale it is -273°C.
Within DNA, a variety of a particular gene is called a(n):
chromosome |
|
heterozygous |
|
allele |
|
homozygous |
The gene is the base unit of inheritance and is contained within DNA. A gene may come in several varieties (alleles) and there are a pair of alleles for every gene. If the alleles are alike, a person is homozygous for that gene. If the alleles are different, heterozygous.
Water has a refractive index of 1.33. Which of the following is true?
light is 1.33 times brighter in a vacuum than it is in water |
|
light travels 1.33 times faster in a vacuum than it does in water |
|
light is 1.33 times dimmer in a vacuum than it is in water |
|
light travels 1.33 times slower in a vacuum than it does in water |
The speed of light varies based on the material that the waves are passing through. The refractive index of a material indicates how easily light travels through it compared to how easily light travels through a vacuum. For example, the refractive index of water is 1.33, meaning that light travels 1.33 times faster in a vacuum than it does in water.
