A substance that affects the rate of a chemical reaction

Answers

Answer 1

Answer:

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.

I will give out 90 points. Please answer!!DNA Polymerase is used to (select all that apply) the answer is not just “synthesize the daughter strand)
-“read” the template strand
-synthesize the daughter strand
-unzip the template strand
-cut the template strand
-cut the daughter strand

IS THE ANSWER 2-5 and not 1??

Answers

The answer is number 4 hope this helps

Final answer:

DNA Polymerase 'reads' the template strand and synthesizes the daughter strand during DNA replication. It does not unzip or cut the template or daughter strands.

Explanation:

DNA Polymerase has specific functions during DNA replication, a process that occurs prior to cell division. Out of the given options, DNA Polymerase is responsible for two actions:

"Read" the template strand: DNA Polymerase 'reads' the DNA sequence in the 3'-to-5' direction and synthesizes the new DNA strand in the 5'-to-3' direction.
Synthesize the daughter strand: DNA Polymerase helps in the synthesis of the new DNA strand (known as the daughter strand) by adding nucleotides to the 3' end of the growing DNA chain.

However, DNA Polymerase does not 'unzip' the template strand, this is the job of another enzyme called DNA helicase. Likewise, DNA Polymerase does not cut the template or the daughter strand. Thus, answers 3, 4, and 5 are incorrect.

Which statement describes what occurs in both animal and plant cells? A) Nitrogen is used for respiration and oxygen is a waste product. B) Oxygen is used for respiration and carbon dioxide is a waste product. C) Nitrogen is used for respiration and carbon dioxide is a waste product. Eliminate D) Carbon dioxide is needed for respiration and oxygen is a waste product.

Answers

The statement that occurs in both animals and plant cells is letter C,Carbon dioxide is needed for respiration and oxygen is a waste product. Theprocess is known as cellular respiration. Cellular respiration is the processof breaking down food such as glucose into carbon dioxide and oxygen. Duringthe process, cellular respiration also releases energy in the form of ATP(adenosine triphosphate) for use by all energy consuming activities of thecell. It is found in the simultaneous process of Gycolysis and Kreb’s cycle.Glycolysis is the breakdown of glucose to two pyruvic acids. These two pyruvicacids will be used for the production of carbon dioxide and water in Kreb’scycle.

The simplest animals that are bilaterally symmetrical and triploblastic (composed of three fundamental layers) are the Platyhelminthes, which are the flatworms. true or false?

Answers

This statement is false. The simplest animals that are bilaterally symmetrical and triploblastic (composed of three fundamental layers) are the Platyhelminthes, however, it is not the flatworms, instead, it is the roundworms who are the simplest animals that are bilaterally symmetrical and triploblastic.

Using the defects method, which of these relationships represents the Law of Cosines if the measure of the included angle between the sides a and b of ∆ABC is more than 90°?a.area of square c2 = -area of square a2 – area of square b2 + area of defect1 + area of defect2
b. area of square c2 = area of square a2 + area of square b2 + area of defect1 – area of defect2
c. area of square c2 = area of square a2 + area of square b2 – area of defect1 – area of defect2
d. area of square c2 = area of square a2 + area of square b2 + area of defect1+ area of defect2
e. area of square c2 = area of square a2 - area of square b2 + area of defect1 - area of defect2

Answers

"area of square c2 = area of square a2 + area of square b2 – area of defect1 – area of defect2" is the one relationship that represents the Law of Cosines if the measure of the included angle between the sides a and b of ∆ABC is more than 90°. The correct option among all the options that are given in the question is option "c".

Answer: c. area of square c2 = area of square a2 + area of square b2 – area of defect1 – area of defect2

(Option C)

Explanation:

The cosine rule helps to determine the different angles and sides of a triangle. The cosine rule is helpful when you need to find the third side of the triangle when the other two sides of the triangle are given and the angle between them.
