Which of the following can serve as an "effector" in physiological feedback loops in animals? Group of answer choices a gland brain spinal cord olfactory receptor (smell receptor)

please type the answer out

Which of the following would serve as an integrator in a feedback loop? Group of answer choices brain muscle gland taste bud

Imagine you are conducting a beta fish experiment. Your experiment consists of finding the response of the betta fish to various vibrations. This is your results (picture). Put your results into a graph, be sure to include error bars if applicable.

The single largest category of receptor type in Animal Cells is A. Enzymatic receptors B. G protein coupled receptors C. Chemically gated ion channels D. Intracellular receptors

Rods and cones differ in how they connect to bipolar cells and eventually to ganglion cells. The major difference is that many cones converge onto one ganglion cell many cones converge onto one bipolar cell many rods converge onto one bipolar cell one rod reaches one bipolar cell

The figure shows the effect of an acidic pH (6.0) on conductance in bare mole rat neurons. Based on this figure, which of the following are affected by pH: channel’s ability to let ions through, channel activation, channel inactivation? (More than one of these might be affected.)

Five different types of taste receptors have been identified in humans.  These are salty, sour, sweet, bitter and umami.  Taste receptors consist of specific types of proteins incorporated into the plasma membrane of taste receptor cells, which are clustered together in structures called taste buds.  All five receptor types are present in each taste bud, which are distributed over most of the tongue surface area.  Olfactory receptors are located in the nasal cavity and consist of several thousand different types, each type specific for a different odorant molecule (ligand).   If you plug your nose, red wine and coffee taste exactly the same.  Explain why this is so.

which of the following is true of chemical signals? - they can only be perceived by the intended reciever - they require physical contact between a molecule and a receptor adapted to fit that molecule - they are perceptible from longer distances, on average, than mechanical signals such as sound waves - they are used almost exclusively in a mating or courtship context

Which of the following provides the most accurate example of active sensing being used by an animal? Male moths use paired antenna to track the pheronome trail of a female moth Electric fish detect the electric field of other nearby electric fish Cats have a tapetum that enhances their night vision for hunting prey in the dark Bats use echolocation to hunt flying insects at night
