Moons like ours are commonplace among the planets and are drawn into orbit by strong gravitation on smaller bodies.
Identical forms of elements on both the Moon and Earth lead scientists to believe that Earth and Moon were formed.
That Earth collided with a Mars-sized body forming the Moon.
The Moon was originally a dwarf planet captured by the Earth's gravitational pull billions of years in the past.
Answer:
C
Explanation:
The most accepted theory on the Moon's origins, the Giant Impact Hypothesis, proposes that a Mars-sized body known as Theia collided with Earth approximately 4.5 billion years ago. This collision ejected material into Earth's orbit, which then formed the Moon.
The most recent and widely accepted theory about the origins of the Moon, known as the Giant Impact Hypothesis, suggests that approximately 4.5 billion years ago, a protoplanet roughly the size of Mars, known as Theia, collided with the nascent Earth. This violent collision resulted in a massive amount of matter ejecting into the Earth's orbit, eventually coalescing and forming what we now know as the Moon. This theory is supported by several pieces of evidence, such as the similar composition of certain isotopes on both the Earth and Moon and the Moon's low density compared to Earth, which suggests it came from the Earth's outer crust.

d. hailstorms
B) gene duplication
C) histone modifications
D) random point mutations
Answer:
A) exon shuffling
Explanation:
Exon shuffling refers to the process of evolution of a new gene that consists of unique combinations of preexisting exons. These novel combinations of preexisting exons are formed when the interspersed repeats of introns of two different genes undergo the process of recombination.
The process of exon reshuffling is responsible for the presence of common domains between two otherwise different proteins of eukaryotes.
Example: Tissue plasminogen activator and epidermal growth factor are very different proteins but share the EGF domain.
