Which of the following indicates the correct reproductive sequence?
ovum → zygote → fetus |
|
zygote → ovum → fetus |
|
ovum → fetus → zygote |
|
none of these are correct |
During intercourse, the penis ejaculates sperm, produced in the testes, into the vagina. Some of the sperm makes their way to the uterus where, if they encounter an egg to fertilize, unite with the ovum to form a fertilized egg or zygote. The zygote then may implant in the uterus and eventually develop into a fetus.
I biome is made up of naturally occurring flora and fauna. Fauna is which of the following?
animals |
|
minerals |
|
plants |
|
habitats |
A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).
The transfer of heat by the circulation or movement of the heated parts of a liquid or gas is called:
diffusion |
|
conduction |
|
convection |
|
radiation |
Convection is the transfer of heat by the circulation or movement of the heated parts of a liquid or gas. Examples of heat transfer by convection include water coming to a boil on a stove, ice melting, and steam from a cup of coffee.
Convert -20C° to F°.

-36 |
To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(-20) + 32\)
\(F° = {-180 \over 5} + 32\)
\(F° = -36 + 32 = -4\)
During continental drift, the drifting plates move across which of the following?
water |
|
sediment |
|
liquid mantle |
|
fault lines |
The crust and the rigid lithosphere (upper mantle) is made up of approximately thirty separate plates. These plates more very slowly on the slightly more liquid mantle (asthenosphere) beneath them. This movement has resulted in continental drift which is the gradual movement of land masses across Earth's surface. Continental drift is a very slow process, occurring over hundreds of millions of years.
