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: Alexandrium catenella is a species of dinoflagellates. Alexandrium has two flagella that enable it to swim. While one flagellum encircles the cell causing the cell to rotate and move forward, the other extends behind the cell and controls the direction.
The cell wall is composed of cellulose Theca.
Length 20 - 48 μm, width 18 - 34 μm
Yellow-green to orange-brown
Forms chains of 2, 4 or 8 cells
The property of DNA which causes it to migrate to the positive pole of the electrophoresis apparatus is B. the negative charge of the DNA.
It acts just like a magnet - positive and negative forces attract.
Answer:
it would be at the bottom of the hill. That's where all of the energy from the descent is at its peak.
the number of oxygen atoms in each oxygen molecule
Explanation:
The subscript in O₂ signifies the number of oxygen atoms in each oxygen molecule.
An atom is the smallest indestructible particle that takes part in chemical reactions.
Molecules are combinations of atoms. They are usually formed when two atoms combines and shares their valence electrons to form covalent bonds.
- An oxygen molecule O₂ is made up of two oxygen atoms.
- The oxygen atoms are held by covalent bonds.
- The 6 coefficient denotes the volume or number of molecules.
