Organisms
Explanation:
Come to think of it,what do organs form
<span>These German physicians discovered that mild electrical stimulation to parts of an animal's brain, particularly the cortex, allowed for different parts of the animal's body to move. They discovered the brain's motor cortex.
Stimulating parts of the left or right hemispheres or halves of the brain resulted to movements of certain body parts on the opposite side. Thus, stimulating parts of the <u>left side of the brain </u>caused specific parts on the right side of the body to move. Meanwhile, stimulating parts of the right side of the brain caused specific parts of the left side of the body to move. </span>
Answer:
B. centromere
Explanation:
Identical chromatids are attached to each other at the centromere.
Other incorrect answers:
A. centriole
The centriole is an organelle that produces the mitotic spindle, also called spindle fibres.
C. spindle
Also called mitotic spindle or spindle fibres, they are produced by the centrioles. The spindle is like long, thin tentacles that attach to the centromeres and move the chromosomes within the cell. During metaphase, they move chromosomes to the equator or metaphase plate. During anaphase, they pull chromosomes apart.
D. chromosome
Chromosomes are condensed DNA. It is the entire structure which includes a centromere. The number of chromosomes in a cell is counted by the number of centromeres.
