In multi-celullar organisms , the cell cycle produces groups of cells that perform the same function. These groups of cells form what it is called a tissue. A tissue is made up of cells that all are specialised to perform the same function. A bunch of tissues form an organ. Organs are more complex in structure and functions.
lots of different organs together form an organ system.
This is true. There are a few websites online that talk about how it happens, I suggest looking them up.
I believe the answer is: Different scientists use different data for investigation.
I say that because different scientists have different equipment, ideas, and have different methods. I hope I was right and i hope it helped and i wasn't to late to answer this question.
Debris (Hydrogen and helium) from the big bang gravitationally clumped together, and frequently these clumps got big enough to start fusion in their centers and form stars.
What is big bang theory?
The Big Bang theory explains how the cosmos expanded from a highly dense and hot starting condition. The evolution of the observable cosmos from the earliest known times up to its later large-scale shape is explained by this prevalent cosmological model. A wide range of observable phenomena, such as the quantity of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure, are all thoroughly explained by the model.
Eventually, the large gaseous balls fuse hydrogen into heavier elements, which causes them to become stars. The periodic table's iron is created when stars combine light elements to create heavier ones.
The remaining elements of the periodic table are created as a result of the stars exploding, producing white dwarfs that explode, or forming neutron stars that collide and explode. The remaining hydrogen gas is now "contaminated" by this other material, and some of it forms an accretion disk in which planets form when it compresses under gravity.

It contains the DNA and control the cell :)
