Giant Impact Theory: The Moon was formed by a collision between Earth and a planet the size of Mars.
Colliding planetesimal Hypothesis: Planetesimals collided and merged to form the Moon.
Capture Hypothesis: As it passed past, Earth's gravity locked the Moon into orbit.
Accretion Hypothesis: The Moon was produced from the same material cloud that created the Earth.
According to scientists, the following are the recognized theories of lunar formation:
What is giant impact theory?According to this idea, a Mars-sized object named Theia collided with Earth, leaving a large portion of the planet to float in space, eventually forming the Moon. This is the most widely accepted idea of all since the Moon is moving away from Earth and its rocks are fairly similar to those of Earth.
1: According to this idea, the Moon was born somewhere else and was drawn into Earth's orbit by its gravity as it passed by.
2. Capture Hypothesis: According to this idea, the Moon and Earth arose from the same cloud of material at the same time.
3. Accretion Hypothesis: According to this idea, a vast number of small rocky objects known as planetesimals crashed and merged over a long period of time.
4. Colliding planetesimal Hypothesis: According to this idea, the Moon was formed by a huge number of small rocky objects known as planetesimals colliding and combining over a long period of time.

Answers
Answer:
The most closely related are amphibians and reptiles.
The least related are amphibians and mammals
Explanation:
Amphibians broke off from reptiles, birds, and mammals around 260 millions years ago and next up are the reptiles which broke off around 225 million years ago. So they are the most closely related
Mammals are the last to break off, around 200 million years ago. So they are the least related to amphibians.

Which statement best describes how Watson and Crick's model used other scientists' work to create a model of DNA?
Answers
Which statement best describes how Watson and Crick's model used other scientists' work to create a model of DNA? They used Chargaff's rule to determine that it contains ribose sugar. They used Franklin's photo to determine that DNA was a double helix. They used Levene's work to determine the number of base pairs in each strand. They used Nirenberg and Matthei's studies to determine that DNA is made of nucleotide
The statement best describes how Watson and Crick's model used other scientists' work to create a model of DNA.
A) They used Chargaff's rule to determine that it contains ribose sugar.
B)They used Franklin's photo to determine that DNA was a double helix.
How, explain your answer briefly?Watson and Crick used pieces of information available from different researchers such as Chargaff's rules and Franklin.
Chargaff had explained that the four kinds of nucleotides are present in a DNA molecule in such a manner that 2 types of nucleotides were always present in the same amounts and the other 2 types of nucleotides were also always present in the same amounts.
The first X-ray picture of DNA, created by Rosalind Franklin using a technique known as X-ray crystallography, which led to Watson and Crick's model of DNA. It explained the helical shape of the DNA molecule.
Thus, The correct statement is-They used Chargaff's rule to determine that it contains ribose sugar. They used Franklin's photo to determine that DNA was a double helix.

do you think that all living organisms show all of the characteristics of living organisms of all time?
Answers
Let’s explore this with an example,
The Characteristics of living things are:
Movement
sensitivity
respiration
reproduction
growth
excretion and nutrition
Human for example are living organisms, but we as organisms do not reproduce constantly or excrete constantly. The cells which make us up are constantly working but because we are multi cellular they are not considered the whole living organism.
If we were looking at a unicellular organism like salmonella bacteria, it might be a bit different. But even in bacteria they reproduce and excrete following a rhythm. They don’t do it constantly all the time, I hope that makes sense.
