Errors can occur when the chromosomes segregate into the gametes during meiosis resulting in egg or sperm with too many or too few chromosomes. As a result, fertilised eggs and the ensuing embryos may have trisomy (an extra chromosome of a particular pair) in each cell or monosomy (one chromosome fewer in each cell).
<h3><u>Processes that form different fossil types:</u></h3>
The remained parts and elements of an organism that live several years ago is called as fossils.
Due to natural processes like weathering, soil erosion and other geological activities fossils are hard to preserve.
Carbonization, permineralization, recrystallization and replacement are the fossil formation processes.
Carbonization is the chemical reaction forming the thin film of carbon of the organic material.
Permineralization includes the fossils of bones and teeth. The recrystallization process is responsible for changing the micro-structure of the organic materials to form the fossils.
Explanation: Methamphetamine is a potent central nervous system(CNS) stimulant that is mainly used as a recreational drug and less commonly as a second line treatment for attention deficit hyperactivity disorder and obesity.
Explanation: If two angles measure 60 degrees, that means that the triangle is equilateral and the third angle is also 60 degrees. You can also just add the two given measures and subtract the sum from 180 degrees.
