Inhibitory neurotransmitters such as glycine and GABA make a postsynaptic cell harder to depolarize by allowing "an influx of Cl-".
<u>Explanation:</u>
The neurotransmitters which have inhibitory influence on the neuron are termed as "Inhibitory neurotransmitters". The major inhibitory neurotransmitters involve serotonin and gamma-aminobutyric acid (GABA) in the brain and brain stem (spinal cord) respectively.
GABA uptake is temperature and ion-dependent as require both 
and 
. Even glycine transporters are also members of the large family of 
dependent neurotransmitter transporters. Both of them with the GABA transporters share approximately 50% sequence identity.
Answer:
This statement refers to Test Cross.
Explanation:
Generally a Test cross involving an individual with a homozygous recessive trait . When a single trait is being studies, a test cross is a cross between an individual with the dominant phenotype but of unknown genotype (either homozygous or heterozygous) with a homozygous recessive individual. If the unknown is heterozygous for a trait, then approximately half of the offspring will display the recessive phenotype. If all the offspring carry dominant phenotype, Then the unknown genotype is homozygous.
