Answer:
The correct answers are: Glucose, Sucrose.
Explanation:
- The given question is an example of a Chemical Reaction.
- A Chemical Reaction can be defined as the process by which two or more substances interact with each other in such a way that a rearrangement of chemical bonds and molecular position occurs in them. This alteration in bonds and molecular position results in the formation of a new substance.
- In a chemical reaction, the substances which are responsible for interacting with each other are called the Reactants.
- In a chemical reaction, the new substances those are formed are called the Products.
- A Chemical Reaction can be represented as follows:
W + X → Y + Z.
- Here, W and X are reacting to form Y and Z.
- So, W and X are the Reactants.
- Y and Z are the Products.
- As the Reactants react to form the Products, so the arrow → is represented from the Reactant to the Product.
- In the given question,
glucose + fructose → sucrose + water
- As arrow → always direct from Reactants to the Products, so the left side of the arrow will be the reactants and the right side of the arrow will be the products.
- Hence, the Reactants are Glucose and Fructose.
- The Products are Sucrose and Water.
- So, Glucose and Fructose undergo chemical reaction to form Sucrose and Water.
The answer is F, false. Natural selection is still involved, with stronger and more procreative individuals spreading their genes. An example of when natural selection is not involved would be when human breeders look for specific traits and breed accordingly.
Cons:
It kills animals
It destroys land and trees
It ruins animals homes
Pros
It clears up lane so we can build
Some rare animals need fire to reduce overhanging plants to live ( it’s called a karner blue Caterpillar btw)
And fire is a natural phenomenon that nature has evolved with
Fish is good to lowering blood pressure because contain vitamin D, and this hormone-like vitamin has properties that can lower blood pressure.
Answer/Explanation:
DNA polymerase is the enzyme responsible for replicating DNA. It is hugely important that is performs its functions accurately, as if incorrect bases are incorporated this can lead to mutations that disrupt the structure and function of genes. It adds nucleotides in a 5' - 3' direction only.
DNA polymerase III also has high processivity, which means that for every time it binds DNA, it is able to add many bases before it becomes dissociated.
A. DNA polymerase avoids the incorporation of improperly paired nucleotides in two ways:
- The first way depends on the structure of the enzyme. If the nucleotide that the enzyme is in the process of adding is not complementary to the template, then the nucleotide will not align with the template, and thus it is more inefficient to add. This inefficiency means the nucleotide is more likely to leave the active site before it is added, and DNA polymerase can replace it with the correct nucleotide.
- It also has proofreading capabilities. This means, when an incorrect base is added, it recognises the error and can fix this. It can do this because it possesses 3'-5' exonuclease activity. That means, it can chop out incorrectly added bases.
B. Ribonucleotides are the nucleotides that are incorporated into a growing RNA molecule. They are different from deoxyribonucleotides because of the differences in the sugar backbone (ribose vs deoxyribose). Their incorporation would disrupt the structure and function of the DNA, leading to problems with transcription and replication.
DNA polymerase avoids incorporating these nucleotides primarily because of the structure of the enzyme. Ribonucleotides cannot fit into the active site of DNA polymerase due to what is called a "steric filter" or "steric gate". This gate/filter function is performed by specific amino acid residues which usually have a bulky side chain and thus block the incorporation of the 2'OH of the ribose sugar (which is lacking in the deoxyribose sugar)
