Answer:
B. misalignment of the chromosomes during anaphase I
Explanation:
Aneuploidy refers to an error in the chromosomal number of a cell. This occurs when the chromosomes fail to separate equally into individual cells, a process called MEIOTIC NONDISJUNCTION. Meiotic disjunction can occur in either the anaphase stage of meiosis I or meiosis II, however, different outcomes are produced.
When chromosomes fail to separate at meiosis I, it results in two gametes that lack that particular chromosome (n-1) and two gametes with two copies of the chromosome (n+1). This means that the four daughter cells will have an incorrect number of chromosomes, hence, the misalignment of the chromosomes during anaphase I will result in four aneuploid daughter cells.
Answer:
Ice caps melting, increased heat causing droughts and wildfires
Answer:
Part A It is associated with peroxisomes and mitochondria.
Part B. It is associated with smooth endoplasmatic reticulum.
Explanation:
The oxidation of long chain fatty acids are produced at the beginning in the mitochondria, it is called B oxidation because there is a carbon in this position that in this process is going to be oxidized to a carbonyl group. The very long fatty acid chains are also oxidized in the peroxisomes.
The cholesterol biosynthesis is made inside the hepatic cells, in the endoplasmatic reticulum. Is a process that starts with acetyl Coenzime A that was oxidized in the mitochondria. This process is regulated by the intake of cholesterol from the diet.
