The right option is; orbital period
T stands for orbital period.
Orbital period is the time a certain astronomical object such as planets takes to complete one orbit (360° revolution) around another object such as sun or stars. Orbital period is expressed in different units of time, usually in years, days or hours.
Answer:
A substance that is more dense per volume has more mass per volume. ...
Explanation:
Thus, sound will travel at a slower rate in the more dense object if they have the same elastic properties.
Answer:
Inbreeding and greater chance of passing deletereous mutations through generations
Explanation:
There are several reasons why small populations are more prone to genetic diseases. One of them is that in small populations there tends to be more inbreeding
, that is breeding between individuals are closely related. Inbreeding increase the chances of offspring being affected by deletereus homozygous genotypes.
On the other hand, the acquisition of a deleterious mutation in a small population is more likely to be spread in that small population than in a large population.
<span>When the landmasses are again collected together in a specific area
The Pangea theory supports the theory of plate tectonics because it is based on the idea that all the present continents were one super-continent. For reasons still unknown, the super-continent got separated and created separate smaller continents. This theory also supports the fact that this movement will continue until the day arrives when all the smaller continents will again merge in a different configuration to create another super-continent. </span>
