Grooming in order to promote social bonding Transmission of learned behaviors such as termite fishing 10. Genetic effects on the neurochemical relationship between levels of noradrenalin and serotonin and aggression in humans have been observed due to deficiencies in genes that code for receptors enzymes vesicles neurotransmitters action potentials 11. Dr. Doolittle wants to find out if serotonin levels play a role in feeding behavior in an animal he discovered in the rainforest, the slobble. When he gives the animal a drug which blocks serotonin in other animals, the animal eats less. Dr. Doolittle has given his slobbles a hormone an agonist an antagonist an amine a weight loss plan 13.
Bats use a sophisticated system of echolocation to locate their insect prey.
As a bat prepares to strike it increases the rate of calling and uses calls with a shallower FM component increases the rate of calling, and uses calls with a steeper FM component decreases the rate of calling, and uses constant frequency calls decreases the rate of calling and uses calls with a shallower FM component decreases the rate of calling and uses calls with a steeper FM component 14. Moths can locate a bat up to 100 ft. away. When the bat is above a moth, the A1 cells in each ear fire equally. When the bat is below a moth, the A1 cells in each ear fire equally. When the bat is above a moth, the A1 cells fire more on the upstroke than the downstroke.
