The sodium amytal test involves the injection of a small amount of sodium amytal into the carotid artery on one side of the neck. This injection anesthetizes the hemisphere on that side for a few minutes.
A method that involves injecting a small amount of a barbiturate into the carotid artery on one side of the head to assess hemispheric functions, usually memory and language. The cerebral hemisphere that was injected selectively becomes impaired for 10 to 15 minutes during this operation.
Various cognitive tests are given while each hemisphere is seperately anaesthetized; deficiencies on these tasks imply that these functions are represented in the anaesthetized hemisphere. Prior to a temporal lobectomy, the Wada test may be utilised in cases with severe and uncontrollable epilepsy. Also known as the Wada technique, intracarotid sodium Amytal test (ISA), Wada dominance test, and intracarotid amobarbital procedure.

Cell membranes are mostly made up of lipids (fats)
Answer:
Deuterium
Explanation:
Deuterium is an isotope of hydrogen with one proton and one neutron in its nucleus.
Thus it has a mass number 2.
Answer:
The amount of target DNA segments doubles with each cycle of PCR.
Explanation:
A polymerase chain reaction is an in vitro technique that is performed in the labs to replicate the DNA from a very small amount of DNA sample. The DNA sample is replicated or double in a very small amount of time that is the target sample doubles after each cycle.
The PCR technique is based on the DNA replication mechanism and thus employs the primer, A Taq DNA polymerase enzyme and the adequate amount of temperature.
Thus, the selected option is correct.
