The pleasure and the reward centers of the brain are control by the neurotransmitter known as dopamine. Besides this, the emotional responses and the movements of a person are also controlled by dopamine.
The reward response from eating ice cream is related to the nucleus accumbens part of the brain. The nucleus accumbens is a part of the basal forebrain, present in each of the brain hemispheres. The dopamine neurons in the VTA (Ventral tegmental area) are activated when the activity such as eating ice cream occurs. These neurons are projected into the nucleus accumbens, and their activation gives a feeling of pleasure.
Hence, the answer is 'nucleus accumbens'.
The right answer is ISOTONIC contraction (not isometric)
During an isotonic contraction, the length of the muscle varies but not the tension. For example, an athlete achieves (approximately) isotonic contraction when he lowers an extremely heavy weight, at a slow and constant speed, against maximum resistance.
Answer:
She inherited the trait from C: both parents.
Explanation:
The daughter, being female, has the chromosomes XX. Since the disorder is <em>recessive</em>, both of the chromosomes need to have the disorder's allele in order for it to activate. The daughter's chromosomes can be labeled as X(c)X(c); where the c stands for the color-blindness allele. She needs one X chromosome from the father, and one X chromosome from the mother. Both of these chromosomes contained the (c) allele, as said before, so the mother has one X(c) and the father has one X(c). This means that she inherited the trait from both parents. The final answer is C.
