Answer:
Because of the angle of the Earth relative to the sun. The higher the sun is in the sky, the higher the UV radiation level.
Explanation:
So, the lattitudes toward the poles that receive sunlight are at an oblique angle, with that being said, the amount of radiation is spread to a larger area than the equator.
In order to survive the winter, monarch butterflies "migrate to warmer areas".
<u>Option: B</u>
<u>Explanation:</u>
- The survival for Monarch butterflies is not possible in any of the United States 'cold winters, therefore they are needed to migrate south and west every autumn to avoid the cold temperatures.
- This species migration usually begins around every year in October, but may begin quicker if the weather turns cold earlier than that.
- Thus they spend their winter hibernation all year round in Mexico and some areas of Southern California where the temperature is warmer.
- If the monarch stays in the Eastern states, typically east of the Rocky Mountains, then they will migrate to Mexico and hibernate in <em>oyamel fir</em> trees.
Debris (Hydrogen and helium) from the big bang gravitationally clumped together, and frequently these clumps got big enough to start fusion in their centers and form stars.
What is big bang theory?
The Big Bang theory explains how the cosmos expanded from a highly dense and hot starting condition. The evolution of the observable cosmos from the earliest known times up to its later large-scale shape is explained by this prevalent cosmological model. A wide range of observable phenomena, such as the quantity of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure, are all thoroughly explained by the model.
Eventually, the large gaseous balls fuse hydrogen into heavier elements, which causes them to become stars. The periodic table's iron is created when stars combine light elements to create heavier ones.
The remaining elements of the periodic table are created as a result of the stars exploding, producing white dwarfs that explode, or forming neutron stars that collide and explode. The remaining hydrogen gas is now "contaminated" by this other material, and some of it forms an accretion disk in which planets form when it compresses under gravity.

The earliest modern humans in Australia, dating to 50 - 40,000 yBP, were found at Lake Mungo. Early modern humans moved into North and South America because of population increase, competition for food and climate change. Modern humans likely migrated to the Americas via walking across the Being land bridge.
Answer:
C.Fewer differences in the amino acid sequencing of a protein show a greater evolutionary relatedness.
Explanation:
Since there are less differences it indicates that they are more related.
