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:
Every nation has its own natural resourse that has abundant and theres other that lack so the countries will trade they abundant for the ones they dont have.
Explanation:
<span>These
islands have different ecologies and most are not connected to each other by landmass.
Therefore, the organism adapt to each of the different ecologies on their
islands. These populations were physically separated due to lack of connection
to each other and would not breed randomly. They therefore formed different species
by allopatric speciation.</span>
Hello!
A polar molecule is where one of the atoms in a molecule has a slight positive charge, and another has a slight negative charge, due to the unequal sharing of electrons.
Water is one of these molecules - the electrons spend more time around the oxygen atom in the center, and less around the hydrogens, so the hydrogen atoms have a slight positive charge, and the oxygen a slight negative.
Therefore, your answer is B, water has a slight negative and a slight positive charge at opposite poles.
Hope this helps!
