Enzymes are proteins that contains ribonucleic acid (RNA) .An enzyme binds to one or more reactant Molecule in order to catalyze a reaction.

Explanation:

1. Enzymes speed up chemical reactions by lowering the Activation Energy, which allows the reaction to proceed much more quickly.

2. During an enzymatic reaction, a molecule of Substrate binds to the enzyme and is broken down into one or more molecules of product, which are released.

3. The induced fit between an active site and its substrate often strains bonds and helps the reaction proceed

4. The specific location within an enzyme molecule where the substrate binds is called the Active site.

5. Lactose takes years to break down on its own. But if exposed to the protein lactase, the reaction proceeds very quickly, while lactase itself remains unchanged. Lactase is an example of an enzyme

6. High temperatures or changes in pH can an enzyme, causing it to lose its shape and biological activity. An inhibitor is a molecule that can bind to an enzyme and prevent the enzyme from working.

7. An enzyme is considered a Catalyst because it speeds up a chemical reaction without being used up.

The colored chromosomes represent chromatids. There are two of each color because one is an exact duplicate of the other. How ma

OverLord2011 [107]

Answer:

92.

Explanation:

92 chromatids are visible for humans at prophase stage because the replication of 46 chromosomes occur. When the replication of chromosomes occur, each chromosome is converted into two chromatids so when 46 chromosomes replication occur then it changed into 92 chromatids. So we can say that there is 92 chromatids in humans in the prophase stage of mitosis.

________ refers to the size and shape of the aggregates of particles of soil.

Softa [21]

The correct answer is soil structure. Soil structure refers to the arrangement of soil separates into units which are called soil aggregates which possess solids and pore space. Aggregates are separated by planes of weakness and are dominated by clay particles. Example of an aggregate is silt and fine sand.

Answer:

B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules

Explanation:

DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.

In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.

A pea plant that has round seeds has the genotype Rr. It is crossed with a pea plant that has wrinkled seeds and the genotype rr

alexandr402 [8]

In order to answer this, you will need to set up a Punett Square (I have attached a picture).

Since Rr is the genotype of round seeds, we know that round must be dominant to wrinkled, and therefore represented by the allele, R.

Since rr is the genotype of wrinkled seeds, we know that wrinkled must be the recessive trait, and there represented by the allele, r.

Since the Punnett Square shows that the genotype ratio is 2Rr : 2rr, or simplified, 1Rr : 1rr, we now know that there is a 50% chance the offspring will have wrinkled seeds.
