Explanation:
The catalyst decreases the activation energy needed.
Catalyst can speed up a chemical reaction by decreasing the activation energy needed. Thus option a is correct.
What is catalyst?Catalyst is defined as a material that allows a chemical process to happen under new circumstances or at a typically faster rate.
It can also be defined as an additive ingredient that can speed up a reaction without being consumed during the process.
There are basically four types of catalyst.
Homogenous catalystHeterogenous catalystHeterogenized homogenous catalystBiocatalystNickel, When making margarine out of palm oil, Ni is employed. In the Haber process, iron (Fe) is employed etc. are some of the example of catalyst.
Thus, catalyst can speed up a chemical reaction by decreasing the activation energy needed. Thus option a is correct.

This is my little sisters question in 6th grade that I forgot the answer to
Answer:
C
Explanation:
There are two kinds of water, fresh and salt water. Salt water is found in the ocean, which means that any answer with salt water, or the ocean, in it is not a correct source of freshwater. A, B, and D, all include the ocean as their answer, which means that they all include salt water, so C is the only option left. Lakes, rivers, water vapor, and ice sheets are all examples of sources of freshwater. I hope your sister gets a good grade!

Explanation:
if the hawk were to removed from the food chain, which consumer would increase in population
Answer:
Everything from the hawk's diet
Explanation:
Mice, rats, shrews, without their main predator, the ecosystem would become unbalanced by the increasing overpopulation of rodents and most likely small snakes that are also on hawks' diet. Another consumer would probably be other animals that eat the hawks' diet. Without a competing consumer, the, let's say snake, population would grow larger.

How do metamorphic rocks work?
Answer: Metamorphic rocks are formed from other rocks that are changed because of heat or pressure. They are not made from molten rock. rocks that do melt form igneous rocks instead. Earth movements can cause rocks to be deeply buried or squeezed. As a result, the rocks are heated and put under great pressure.

Rico and Bree are camping and have potatoes wrapped in foil to eat. Bree put her potato in the campfire for a while, but Rico did not. Now Bree's potato has a high temperature. What is the difference between the molecules of the two potatoes? *
There is no difference because both potatoes are made of the same type of molecules.
What is Molecules?Molecule is a group of two or more atoms that are bound together with the help of some attractive forces. These attractive forces are known as chemical bonds. It is the smallest particle of a substance that has all the physical and chemical properties of that substance.
Atoms have a single nucleus with a positive charge protons surrounded by a cloud of negatively charged electrons. When these come close to each other, the electrons interact with each other and with the nucleus, lowering the total energy of the system, then the atoms bond together to form a molecule.
There are three types of molecules:
1. Molecule of an atom
2. Molecule of an element
3. Molecule of a compound
Thus, there is no difference because both potatoes are made of the same type of molecules.

Answer:
In the process of transcription, DNA is used as a template for making another type of nucleic acid called RNA. The process begins when the enzyme RNA polymerase binds to a region called the promoter.
Explanation:
I took the test lol
Transcription is a particularly important stage in gene expression, since it is the main method by which the cell regulates which proteins are to be created and at what rate.
What is the role of enzyme in the transcription process?RNA polymerase, which creates a complementary strand of RNA using a single-stranded DNA template, is the primary enzyme involved in transcription.
Each new nucleotide is added to the 3' end of the strand as RNA polymerase constructs an RNA strand in the 5' to 3' orientation.
The first step in unlocking a cell's genetic code is transcription. Enzymes known as RNA polymerases construct complementary RNA molecules to a section of one strand of the DNA double helix during transcription.
Therefore, In the process of transcription, DNA is used as a template for making another type of nucleic acid called RNA. The RNA polymerase enzyme binds to a region known as the promoter to start the process.

How do molecules move differently if the temperature is increased?
Answer:
Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion
