Answer:
The correct answer is A. The two cerebral hemispheres are separated by the longitudinal fissure.
Explanation:
The longitudinal or intercerebral fissure is a deep cleft that divides the brain longitudinally into two hemispheres (the right and the left) joined together by the corpus callosum. Other fissures, such as the central sulcus, the lateral sulcus and the internal perpendicular fissure, divide each hemisphere into large cerebral lobes, which in turn have cerebral convolutions.

Answer:The net force is the sum of all the forces acted upon an object. The direction of force depends on which side you are taking as a positive and negative force. If the force of 22 newtons is positive and the force of 13 newtons is negative, they are actng on the object on different directions, thus in order to get the net force, we just sum them up.
newtons
The net force is +9 Newtons.

DNA isolation is a process of purification of DNA from sample using a combination of physical and chemical method while on the other hand, Polymerase chain reaction (PCR<span>) is a technique used in molecular biology to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence.</span>
