A non-disjunction in meiotic anaphase occurring in either an egg or sperm might produce a human zygote with 45 chromosomes. A condition in which human contain 45 chromosomes instead of 46 chromosomes is called aneuploidy or abnormal chromosome number.
<h3>What is aneuploidy?</h3>
The occurrence of one or more extra or missing chromosomes leading to an unbalanced chromosome complement, or any chromosome number that is not an exact multiple of the haploid number (23). It is the presence of an abnormal number of chromosomes in a cell, for example a human cell having 45 or 47 chromosomes instead of the usual 46. An extra or missing chromosome is a common cause of some genetic disorders. The most common cause of aneuploidy happens during cell division when the chromosomes do not separate properly between the two cells.

Answer:
C) Is the right answer
Explanation:
chemical reactions occur when a substance is changed into a whole 'nother substance, and cannot be changed back.
how do I know this?
I just learned it today... UwU
I hope this helps!!
That is false. Physical characteristics of an organism are genetically passed down.
—Evidence—
A characteristic that an organism can pass on to its offspring through its genes.
The set of information that controls a trait; a segment of DNA on a chromosone that codes for a specific trait.
Heredity is the biological process responsible for passing on physical traits from one generation to another.
The correct answer should be (d) The Krebs cycle
After Glycolysis, the Krebs cycle begins in the matrix of the mitochondrion.
Marine biologists study changes in the ocean. so they will look at the chemical composition of deep waters and see how consecrated the oxygen is. They will also study the movements of the plates because when planted move it usually makes new food for deep life
they will also check animal concentrations in certain areas.
Another thing they do is track animal movements. this could be by putting a tracker on a whale or a shark or anything and watching its depths it goes or watching the distance it goes in a day.
