Typically, the actual yield is lower than the theoretical yield because few reactions complete (i.e., are not 100% efficient) or because not all of the product in a reaction is collected. It is also conceivable for the real yield to exceed the theoretical yield.
What is theoretical yield ?
Theoretical yield is what would be obtained if 100% of the reaction was completed and no product was wasted in any way; however, procedures are not this efficient. Everything is dependent on the experimenter's precision and the reaction. Some reactions are reversible, meaning that less than 100% of the reaction proceeds to completion; some reactions do not go to completion because they require a large amount of energy or additional time, for example. Substances in the reaction may be lost throughout the method or difficult to separate from other sections of the experiment. In chemistry, some degree of inaccuracy is always expected.

Answer:
A. ✔️Substitution
B. ✔️Insertion
C. ✔️Deletion
Explanation:
In A, the type of mutation that is shown is Substitution. In B, the type of mutation shown is Insertion and in C, the type of mutation shown is Deletion.
Mutation refers to the change in the DNA sequence. This occurs in an organism. In gene mutation, the structure of DNA molecule changes and produces a different allele of a gene. While in chromosome mutation, there is the change in the structure or number of the whole chromosomes in a particular cell.
Actually, mutations can take place both in prokaryotic cell and in eukaryotic cell.
In genetics, there are: Substitution, Insertion and Deletion mutations.
Substitution mutation is an exchange of one base for another. Insertion mutation is simply addition of one or more nucleotide pairs in a DNA sequence while Deletion mutation refers to the situation in which a sequence of DNA is left out when there is DNA replication.
Oxidation reaction
is a type of reaction wherein there is a
loss of electrons. An oxidation reaction may also be a reducing agent. Example
is the reaction Zn + 2H+ = Zn2+ + H2. When you separate them by their half cell
reaction, you have 2H+ 1e- = H2. H here is the reducing agent and has lost 1
electron in the process.
Answer:
pancreatic amylase, lingual amylase, intestinal amylase
Explanation:
When considering a sugar drink, the enzymes involved in its digestion are first the alpha amylase found in saliva, responsible for degrading starch molecules, thus generating unique molecules of monosaccharides. Then the ones in charge of continuing with the digestion will be the pancreatic amylase and the intestine at the duodenal level.
