Pick one of the following genetic variations that have occurred in human evolution. Then pick one of the three causes of genetic

Marrrta [24]

Smaller teeth and jaws are due to genetic variation, which occurred by mutations (errors in DNA replication) and were selected to fill a suitable niche.

<h3>What is evolution?</h3>

Evolution is the mechanism of change of one species to adapt given environment, whereas mutations are the raw material for evolution.

In this regard, scientific evidence supports the fact that jaws evolved to become shorter in humans and thus adapt to a pastoral lifestyle.

In conclusion, smaller teeth and jaws emerged by mutations and were selected to fill a suitable niche.

Two balloons having the same charge of 1.2 × 10-6 coulombs each are kept 5.0 × 10-1 meters apart. What is the magnitude of the r

Pavel [41]

The answer is 5.2 × 10-2 newtons.

To calculate this, we will use Coulomb's Law:
F = $\frac{k * Q_{1} * Q_{2} }{ r^{2} }$
where F is repulcive force, k is constant, Q is charge, r is distance between charges.

If:
 $Q_{1}$ = $Q_{2}$ = 1.2 × $10^{-6}$ C²
r = 5.0 × $10^{-1}$ C²
k = 5.0 × $10^{9}$ $\frac{N*m^{2} }{ C^{2} }$

Then:
 $F = \frac{5.0* 10^{-1} \frac{N* m^{2} }{ C^{2}} * 1.2 * 10^{-6} C * 1.2 * 10^{-6} C }{(5.0* 10^{-1} m)^{2}}$
⇒ $F= \frac{9 * 1.2 * 1.2 * 10^{-3} N }{25* 10^{1} }$
⇒ $F = \frac{12.96* 10^{-2} }{25} N$
⇒ $F = 5.2 N$

The first trilobites found in China were discovered in a layer of rock called the Devonian Shale. If you were hunting for trilob

olasank [31]

Answer:

Rocks which were underwater long time ago.

Explanation:

If we were hunting for trilobites in Canada, we look for those types of rocks where once water present on it because trilobites are the organisms which lived in the marine ecosystem so if they are present in marine so we have to look those rocks which were underwater millions of years ago. Trilobites are the extinct marine arthropods that were present around 521 million years ago.
