describe how the position of the Earth Moon and Sun can be detected on Earth
Answer:
As the Earth rotates, it also moves, or revolves, around the Sun. As the Earth orbits the Sun, the Moon orbits the Earth. The Moon's orbit lasts 27 1/2 days, but because the Earth keeps moving, it takes the Moon two extra days, 29 1/2, to come back to the same place in our sky.

Why does the mitochondrial gene tree suggest a later split? Why the disparity between the nuclear gene tree?
this is the link: https://learn.genetics.utah.edu/content/evolution/bears/
Answer:
Why does the mitochondrial gene tree suggest a later split?The mitochondrial gene tree suggests a later split because it occurred hybridization later in time, with the transference of the brown bear mitochondrial genetic information to the polar bear population. So the mitochondrial gene tree exhibits a later divergence.
Why the disparity between the nuclear gene tree?Because the first divergence event of the common ancestor occurred 60,000 years ago, evidenced by nuclear DNI and mitochondrial DNI. However, 100,000 years ago, concerning the mitochondrial genetic material, the hybridization event defined a new more recent common ancestor between the two species.
Explanation:
The use of mitochondrial DNA might present a few problems that need to be considered in evolution studies. It involves only one locus, so it has some limitations when reconstructing history, especially if the locus went through any process, such as natural selection, bottleneck events, or its transference to another population due to hybridization. There is also a high possibility of an incomplete reconstruction of the population history if males and females have different dispersal patterns.
The most proper way of reconstructing history is by complementing mitochondrial information with nuclear genetic information and evaluating their concordancies.
In the exposed example, 600,000 years ago, the original species split into the polar bear and the brown bear. But 100,000 years ago, hybridization occurred between a brown bear female and a polar bear male. The offspring joined the polar bear population, carrying the female genetic information, nuclear and mitochondrial. With time, these individuals interbred with the polar bears, diluting the nuclear brown bear genetic information. However, females carrying the brown bear mitochondrial DNI seemed to be more successful reproductively than the polar bear females. The mitochondrial information, hence, has been in the population for many generations, until today. And this information came from a more recent common ancestor, compared with nuclear genetic information.

Explanation:
Red-eyed tree frog eggs can hatch up to two days earlier than average when they detect vibrations. However, if they hatch more than two days earlier than expected due to vibrations, the embryos are typically not developed enough to survive outside of the egg. Explain how natural selection inhibited frog eggs from hatching any earlier than two days before expected hatching. Explain your answer in 1–2 sentences.
Natural selection inhibited the eggs from hatching before expected because this trait is negative in terms of survival and reproduction.
How does natural selection work?Natural selection is a natural process that causes evolution over time. This mechanism implies only individuals with traits that represent an advantage for survival and reproduction will prevail over time, which causes the traits of these individuals to become dominant.
For example, if in a population of deer male deer with big antlers are more likely to survive and reproduce, it is expected after some generations this trait is dominant.
How does natural selection work in the red-eyed tree frog case?In this situation, we know that if an egg hatches before time the embryo is not likely to survive. This means this trait is a disadvantage in terms of survival and reproduction, and due to this and as a result of natural selection the trait is not dominant.

The diagram below shows a hand warmer. It uses a controlled burn of a type of lighter fluid called naphtha.
The device has a refillable reservoir that holds the naphtha liquid. The fuel moves into a glass fiber burner, which absorbs the fuel and allows it to burn slowly without producing a flame. Oxygen reaches the burner through the holes on the cap at the top of the device. As the fuel is burned, heat is conducted to the metal casing of the device.
When the hand warmer is tested, it becomes too hot and uncomfortable to hold. How could the device be modified to solve this problem?
A.
by increasing the size of the fuel reservoir so that it can store more liquid fuel
B.
by replacing the glass fiber burner with a material that does not soak up liquid fuel
C.
by attaching a covering to reduce the amount of oxygen entering the device
D.
by using a fuel that is more flammable than naphtha so that the fuel can be used faster
Answer:
