Answer:
All living organisms are made up of one or more cells
All living organisms reproduce by passing on specific genetic information to future generations
Only living organisms are capable of evolving
Only living organisms require an input of energy to drive cellular activities
All living organisms grow by increasing cell size or cell number.
Explanation:
More than one million Earths could fit inside the Sun if it were hollow. The Sun has a radius of 696.340 km / 432.685 mi and a diameter of 1.39 million km / 864.000 mi.
when an atom gains or loses an electron, it becomes an ion. Ions formed by the loss of an electron have a positive charge, and those formed by gaining an electron have a negative charge. Positive ions are called cations, and negative ions are called anions.

Answer:
The correct answer is c. adding a catalyst for the reaction
Explanation:
The function of a catalyst in a chemical reactionis to increase the rate of reaction by decreasing the required activation energy which is clearly illustrated on energy diagrams. It is not consumed in the reaction and can be reused repeatedly,as such, only small quantities of catalysts are required in the reaction. Catalyst provide a separate route for a chemical reaction to proceed at a lower activation energy than an uncatalysed reaction
The process of speeding up a chemicals reaction by the addition of a catalyst is known as catalysis
