Answer:
c. add coefficients as needed
Explanation:
A chemical equation is defined as the equation that shows changes in a chemical reaction. A chemical equation consist of reactant and product, reactant is at left side of the arrow and product is at right side of the arrow.
Reactant => Product
While balancing a chemical equation, the basic rule is to balance the coefficient as required. Coefficient represents the number of molecules and is used at front of a chemical symbol. Change in coefficient helps balance the number of atoms or molecules of the substances on both the sides of the arrow.
Subscripts are never allowed to change because it can change the chemical involved in the reaction.
Hence, the correct answer is "c. add coefficients as needed".
Answer:
False
Explanation:
A liquid has a definite shape and takes on the volume of its container. A gas has both the shape and the volume of its container. The particles in a gas cannot be compressed into a smaller volume. Liquids tend to contract when heated.

Answer: Static electricity will help in seed dispersal in cone bearing seeds.
Explanation:
Static electricity is the stationary electric charge produced by the friction. The static electricity can be produced by the turbulence or air currents in the storm clouds. This is responsible for the cause of lightening phenomena.
The cone bearing seeds exhibit cones that are hard and woody in nature. The static electricity due to the effect of lightening generate electrical shock which breaks open the cone and disperse the seeds. Thus the static electricity is important for seed dispersal in cone bearing trees.
The hydrogen bonds between molecules of hydrogen peroxide loosen as temperature rises toward the optimal point, facilitating catalase's reaction with the molecules. The enzyme denatures and its structure is affected if the temperature rises above the ideal level.
<h3>What is a catalase?</h3>
The catalase is an enzyme that is responsible for reducing hydrogen peroxide.
<h3>What does catalase do?</h3>
- This enzyme is in charge of neutralizing hydrogen peroxide through its breakdown
- It hence preserves an ideal level of the molecule in the cell that is also necessary for cellular signaling processes
<h3>Importance of catalase enzyme:</h3>
- Almost every organism that is exposed to oxygen contains the very common enzyme catalase.
- In order to prevent oxidative damage, which can happen when cells or other molecules in the body come into contact with oxidative chemicals, catalase serves as a protective barrier in live cells.
