Through the study of meteorites, their chemical composition of silicates—material made of silicon and oxygen. Others contain metal—nickel and iron. Knowing what the meteorite was composed of lets you know where it came from. Chondrites are composed of hardened lava - this is occurred at the beginning of the solar system (4.5 mya).

Define a chromosome and give more details about it​
solmaris [256]
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.

Chromosomes are not visible in the cell’s nucleus—not even under a microscope—when the cell is not dividing. However, the DNA that makes up chromosomes becomes more tightly packed during cell division and is then visible under a microscope. Most of what researchers know about chromosomes was learned by observing chromosomes during cell division.

URGENT! What results would you expect to see if exercise does not increase bone mass?
Nikitich [7]

When exercise does not increase bone mass, it has been observed that the risk of bone fractures increases due to osteoporosis.

<h3>What are the benefits of exercise to bone mass and density?</h3>

Bone mass refers to the mass of the bones in a living organism as a result of the deposition of minerals within the bone.

An increase in bone mass is directly related to the strength of the bone.

Strong bones have high bone masses whereas weak bone have low bone mass.

Physical activity have been shown to improve bone mass by increase the mass of deposited minerals in the bone.

Exercise such as walking, running, jogging, and other forms of exercise have been shown to improve bone mass and hence, the strength of bones.

However, when exercise does not increase bone mass, osteoporosis is observed which results in bone fracture.

In conclusion, the strength of a bone is directly related to the bone mass which is directly related to the mass of minerals deposited within them.
