Answer:
C. Balancing a chemical equation simply means ensuring that the same numbers of atoms of the elements which are involved in the reaction (reactants) are represented in the result of the reaction (products). This demonstrates that matter is not created nor destroyed in a chemical reaction.
Explanation:
The products of a reaction contains a certain number of each atom constituting each product;
Matter cannot be created or destroyed so the reactants must contain the same number of each atom;
Balancing the equations means this will be the case and hence, this will demonstrate the number of each reactant atom/molecule necessary for the reaction to proceed
The definition of faith contains two aspects:intellectual assent and trust. intellectual assent is believing something to be true.Trust is actually relying on the fact that something is true.A chair is often used to help illustrate this. Intellectual assent is recognizing that a chair is a chair and agreeing that it is designed to support a person who sits on it. Trust is actually sitting in the chair.
My faith with God is strong and I never tend to ignore it....!!!
Answer:
In the 1960s, scientists found evidence that new material is indeed erupting along mid-ocean ridges. The scientists dived to the ocean floor in Alvin, a small submarine built to withstand the crushing pressures four kilometers down in the ocean. In a ridge’s central valley, Alvin’s crew found strange rocks shaped like pillows or like toothpaste squeezed from a tube. Such rocks form only when molten material hardens quickly after erupting under water. These rocks showed that molten material has erupted again and again along the mid-ocean ridge.
When scientists studied patterns in the rocks of the ocean floor, they found more support for sea-floor spreading. You read earlier that Earth behaves like a giant magnet, with a north pole and a south pole. Surprisingly, Earth’s magnetic poles have reversed themselves many times during Earth’s history. The last reversal happened 780,000 years ago. If the magnetic poles suddenly reversed themselves today, you would find that your compass needle points south.

I found this somewhere.
5% of $20 is $1; 5% off $20 is $19
Answer: Directional selection
Explanation:
In the population genetics, directional selection is the mode of selection during which the extreme phenotype are favored more than the other phenotype.
This causes the allele frequency to shift towards the time in the direction of that particular phenotype.
Here, in the question the acid tolerant plant species is favored over the other phenotype.
Hence, the correct answer is option D
