In the fourth century BC, Aristotle observed a phenomenon in which he saw a circular shadow on the Moon. He argued that Earth was a sphere based on this observation. What phenomenon caused the shadow on the Moon? *


a solar eclipse

a lunar eclipse

a spring equinox

a summer solstice

Answers

Answer 1

Answer:

a lunar eclipse

Explanation:

The shadow that Aristotle saw was caused by a lunar eclipse. At that time the sun, earth, and the moon nearly straight alignment caused the Earth's shadow to be reflected on the moon. This shadow is what ultimately led Aristotle to believe that the Earth was a sphere. This should not be confused with a solar eclipse which is similar but instead the sun, moon, and earth align in that order which causes the moon to completely block the sun to anyone on earth.

Where are the statements?

Explanation:

Which conclusion about the growth of new bacterial cells does the experiment support?
O Heat helps bacterial cells grow new bacterial cells faster.
New bacterial cells can only arise from preexisting bacterial cells.
The amount of available nutrients impacts the growth of new bacterial cells.
Growth of new bacterial cells depends only on the presence of nutrients.

Answers

Answer: New bacterial cells can only arise from preexisting bacterial cells.

Explanation:

Option A is wrong because when heat was applied, there was no new bacterial growth. Most likely because the heat killed the bacteria cells. Option C is also wrong as well the third trial had nutrients but no new bacteria cells grew.

Option D is wrong because in Trial 1, there were nutrients and yet no new cells were formed. This means that growth of new cells depends on more than nutrients alone.

This leaves option B as the correct answer which is proven by the lack of growth of new cells when there were no pre-existing ones in trial 3.

Hopetown is farther from the equator than kamina. Which location has colder air temperature and why

Answers

Answer:

Hopetown

Explanation:

The farther from the equator the colder the air temperature. This is because the equator is the point on planet Earth that receives the largest amount of solar energy, so the regions that are above this line are the warmest in the entire planet. The further away from the equator a region is established, the less solar energy it receives, which is why the poles are so cold. In this case, we can say that the Hopetown temperature is colder than the kamine temperature.
