Answer:
C
Explanation:
A substance that affects the rate of a chemical reaction is typically referred to as a "catalyst."
A catalyst is a substance that increases the rate of a chemical reaction by providing an alternative reaction pathway with a lower activation energy. The catalyst itself is not consumed in the reaction and remains unchanged at the end of the reaction, making it available for use in subsequent reactions.
Catalysts work by providing an alternative mechanism for the reaction that has a lower energy barrier, allowing the reaction to occur more rapidly. They facilitate the formation of reaction intermediates and transition states, making it easier for the reactants to transform into products.
Catalysts are widely used in various chemical processes, both in laboratory settings and industrial applications, to speed up reactions, improve efficiency, and reduce the amount of energy needed for a reaction to occur. They play a crucial role in fields like chemistry, biochemistry, and industrial manufacturing, enhancing the production of essential materials and products.

A substance that affects the rate of a chemical reaction is ________.
The chance that their first child will have type O blood is 25% since the genotypes of offsprings are .
An allele is a particular form of genetic information that can be found in our DNA at a particular spot on a certain chromosome. This form of genetic information is known as an allele. IA, IB, and i are the three distinct alleles that can determine a person's blood type. I is the most common. These three alleles can be referred to as A (for IA), B (for IB), and O for the sake of simplicity (for i).
Therefore, when a man heterozygous for blood type A marries a woman heterozygous for blood type B the chances that their first child will have type O blood is 25% since the genotypes of offsprings are .

Answer: The work done by the ramp against the force of gravity is -343 J
Explanation:
Work is defined as the force that is causing the movement or displacement of an object.
Mathematically,
We know that:
where,
W = work done by the ramp = ?
m = mass of the box = 7 kg
g = acceleration due to gravity = (Negative sign appears because it is acting against the gravity)
d = displacement = 5 m
Putting values in above equation, we get:
Hence, the work done by the ramp against the force of gravity is -343 J
