<h3><u>Answer;</u></h3>
When particles were pulled together so tightly they combined.
<h3><u>Explanation</u>;</h3>
- The solar nebular hypothesis describes the formation of our solar system from a nebula cloud made from a collection of dust and gas.
- It is believed that the sun, planets, moons, and asteroids were formed around the same time around 4.5 billion years ago from a nebula.
- According to this theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust.

Fossils are one of the best evidence of evolution, mainly because they are the remains of living organisms from the past, which allow us to compare them with living organisms. However, the fossil record is notoriously incomplete and it is also biased in favor of animals with hard body parts, such as skeletons and shells. Soft bodied organisms and soft body parts are rarely preserved and there are often huge gaps in some evolutionary sequences. For example, Archaeopteryx is the earliest known bird, but it is already a bird, nothwithstanding some of the features that are unquestionably reptilian. The earliest known reptile with feathers is Longisquama, but there is a gap of some 75 million years between Longisquama and Archaeopteryx, and nothing has yet been found that are intermediate between these two important fossils.
Finally, DNA is virtually unobtainable from fossils, making it nearly impossible to compare the DNA of most fossils with living organisms. In terms of phylogenetic tree construction, DNA data is far superior to fossil evidence. However, if not for the existence of fossils, DNA data alone would be unconvincing as evidence of evolutionary change.

The specimen is VIRUS.
A virus is an infective agent which can only reproduce within a living cell. All virus contain genetic materials, either DNA or RNA but not both. A protein coat usually surround the genetic material of the virus. Virus can be classified based on the genetic material found in them and the size of the material.
I think it does make up all of the body tissues and organs.
Answer:
Angiosperms evolved during the late Cretaceous Period, about 125-100 million years ago.
