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.

Answer:
Atom-Molecule-Organelle-cell-Tissue
Explanation:
Biological is a hierarchical system that arranges biological structures in the order of complexity.
In the given sequence,
- The atom is the simplest and smallest unit
- Molecule-It is made up of two or more atoms
- Organelle-A specialized structure within a cell
- Cell- Is the smallest functioning unit of life and it contains organelles
- Tissue-an assembly of cells that perform a specific function.
B. Decreasing the surface area of solid reactant;
Why? Collision theory suggests that the more opportunities for reactants to come into contact or "collide" with other reactants, the faster the reaction will take place. Hence, decreasing the surface area will decrease the probability of collisions between reactants thereby decreasing reaction rate.
True because its trueeeeee easy
