Answer:
Blood types: AB, A, B, and O in ratio 1:1:1:1
Explanation:
The ABO blood group system is employed in Humans. The alleles for blood type A (A) and blood type B (B) are dominant over the allele for blood type O (O).
If a man who is heterozygous for blood type A (AO) marries a woman who is heterozygous for blood type B (BO), the following gametes will be produced by each parent:
AO - A and O
BO - B and O
Using these gametes in a punnet square, the following proportions of offsprings will be produced:
Blood type AB - 1/4
Blood type A - 1/4
Blood type B - 1/4
Blood type O - 1/4

Answer:
Effects of Ecstasy on the nervous system:
- stimulant
- psychedelic
- neurotoxic
- abnormal neurotransmitter function
- injured cognitive functions (e.g., sleep and pain control)
Explanation:
Ecstasy, also known as MDMA (3,4Methylenedioxymethamphetamine), is a stimulant and psychedelic drug that may exhibit neurotoxic effects. This amphetamine analog (i.e, drug based upon the amphetamine structure) has several effects on the nervous system which are caused by the increase in the activity of three major neurotransmitters: serotonin, dopamine, and norepinephrine. It has been shown that Ecstasy alters the central nervous system, producing neurotoxic effects and affecting brain functions including, among others, cognitive functioning and development, neuroendocrine release mechanisms, sleep control, pain control, etc.
