Answer:
deletion of a chromosome.
Explanation:
Changes usually occur in the nuclear material (chromosomes) of a cell. These changes are called MUTATION. A mutation, depending on how it occurs, consists of different types. Mutation can result into deletion of a chromosome or addition of a chromosome.
Deletion mutation is the removal of a part of the chromosome segment or chromosome while Insertion mutation is the addition of a part of the chromosome segment to the original chromosome. Both insertion and deletion can be detrimental to the organism as it can lead to the serious genetic disorders, however, deletion of a chromosome has the most adverse effect.
During deletion mutation, information encoded in a particular chromosome is lost completely which can make the resulting individual deficient of certain traits that makes him/her normal but in Insertion mutation, a different chromosome is added which can sometimes be beneficial to the resulting organism e.g can confer resistance to certain unfavorable condition.

For example, enzymes are proteins that speed up chemical reactions in the body and hormones, like insulin, are proteins that regulate the activity of cells or organs. Some proteins transport materials throughout your body, such as hemoglobin, which is the oxygen-transporting protein found in your red blood cells
The loop of Henle conserves water and minimizes the volume of urine.
Answer:
The correct answer would be "NADH delivers its electrons to complex I and FADH₂ deliver its electrons to complex II" in cellular respiration.
There are mainly four complexes associated with electron transport chain of cellular respiration.
Complex I or NADH: ubiquinone oxidoreductase is the complex at which NADH is oxidized to form NAD⁺. The free electrons are transported with the help of ubiquinone.
Complex II or succinate dehydrogenase is the complex associated with oxidation of FADH₂ to FAD⁺. It also transports the free electrons with the help of the ubiquinone pool.
Complex III or cytochrome bc1 complex transport free electrons from ubiquinone to the cytochrome C which is a water-soluble electron carrier.
Complex IV or cytochrome c oxidase transport the free electrons to oxygen to form water.
