Explanation:
E, will be lower- this denotes the activation energy
Activation energy is the specific amount of energy required for a chemical reaction to occur. Enzymes lower the activation energy, significantly speeding up the reaction rate.
Further Explanation:
Enzymes are proteins that catalyze reactions by working on substrates to promote reactions-including amylase breakdown of broad polysaccharides. Some enzymes like catalase, allow for the degradation of hydrogen peroxide into oxygen and hydrogen; the pH, temperature, and involvement of inhibitors influence their specificity.

Out of the following given choices;
contain ribose
consist of two strands
made of nucleotides
have an R group
The answer is 'made of nucleotides'. This is because out of the choices, DNA and RNA share the similarity of being made of nucleotides. However, while DNA is made of deoxyribose nucleotides, RNA is composed of ribose nucleotides. This difference is that in deoxyribose nucleotide, the 2nd carbon has a hydroxyl group while ribose nucleotide has hydrogen.
sludge
<span>Sewage treatment is also known as wastewater treatment. It is
a process whereby contaminant is removed from wastewater. Thus, chemical,
biological and physical process are commonly used to remove contaminants from
wastewater and the by-products of wastewater treatment is usually inform of
solid waste known as sewage sludge.</span>
Answer:
One band of light density and one band of heavy density.
Explanation:
According to conservative model of replication, the original strands do not separate from each other during replication. Hence, after replication the old strands are together and the new strands are together.
Here, cells were grown in 14N medium first so 14N was used for DNA replication and all DNA molecules had 14N. When the cells were transferred to 15N medium, only 15N was available for replication process. New DNA molecules would be synthesised using 15N (15N15N) and old DNA molecules have 14N (14N14N). Hence, in density gradient one band will be of light density (14N14N) and one band will be of heavy density (15N15N).
The answer would be serratus anterior.
Sentence form: The serratus anterior muscle is important in thrusting movements of the arm, much like a boxer's jab punch.
