Textbook Question
Chapter 27, Problem 17PS
Interpreting Data Marine mammals, such as seals, whales, and dolphins, have adapted to their watery environment in many ways, including a respiratory system that allows for long underwater dives and a language used to communicate through water Another adaption studied by researchers involves bottlenose dolphins. These dolphins spend approximately 33% of a 24-hour day with one eye open and the other closed, alternating which eye is open and which is closed at intervals of approximately 1 hour. During this time, the animals continuously swim and intermittently rise to the surface of the water to breathe air. Look below at data collected on brain activity in bottlenose dolphins. Why do the dolphins swim with one eye open and the other eye closed—that is, what are they doing? How does their brain activity relate to what is happening with their eyes? Why might this be a successful adaptation?

at a large
Assume that you are the nurse
elementary school where children frequently come to
you with nosebleeds.
Design an experiment to test whether dropping
keys down the back of the neck causes nosebleeds to
stop. (Assume parents of all children in the school have
given permission for their participation in the
experiment and you have followed ethical guidelines for
research with human subjects.
One possible explanation for why keys down the
back might actually be effective in stopping a nosebleed
is that they are cold, causing blood vessels to constrict.
Treatments should be randomly assigned to the
children. Describe how you accomplish this.
That is, when a child with a nosebleed comes
to the nurse's office, how will you know which
treatment he or she should get?
Ture or False:(T/F) A bee would detect the odor of the flowers using trichoid sensilla located on the antennae and the olfactory information would be processed in the glomeruli of the deuterocerbrum and incorporated into olfactory learning in the corpora pedunculata of the protocerebrum.(T/F) A bee would monitor and control flight speed using interommatidial hairs and the optomotor response.(T/F) Stresses and strains on the exoskeleton during flight would be monitored by basiconic and coeloconic sensilla located in the wing hinge.
“Animal personality” has been defined as consistent differences between individuals that persist over time.
Briffa & Greenaway (2011) studied wild beadlet anemones (Actinia equina) to see whether they display ‘personalities’.
They disturbed individual anemones with a jet of water (which causes their tentacles to retract) then recorded how long it took each anemone to reopen (seconds). The experiment was then repeated two weeks later to see whether individual anemones showed consistent reopening times (consistency indicates they have ‘personalities).
a)Sketch an appropriate graph to show whether any association exists between the day 1 and day 14 anemone responses. What kind of graph is it?
b)Is a strong association present? (i.e., do anemone’s have ‘personalities’?)

What about absolute numbers of animals—are there more animals on land or in the ocean?arrow_forwardplease asap. thanku You discover a new species of frog in extremely dark parts of the Amazon rain forest. You hypothesize that this frog detects light using a mechanism similar to mammals.

- The tympanic membrane is a covering that transmits sound to the inner portions of the frog ear. It doesn’t detect sound – it just transmits it. It would be similar to how the human eardrum works. It also protects the frog ear from water/debris. Some frogs have large external tympanic membranes; others have very small ones. Some frogs do not have them at all – they transmit sound to their ears in other ways. Look at the Coastal Plains leopard frog and the bull frog. Be able to identify the tympanic membranes, and the dorsolateral or supratympanic folds on both.

- Listen The following passage comes from an abstract in a study about analyzing hearing loss in twins: "A clinical and genetic study on 25 twin pairs with at least one deaf member was performed. Concordance rate of hearing loss was 0.88 in MZ and 0.50 in DZ pairs" (MZ =monozygotic or identical twins. DZ -Dizygotic or fraternal twins). From this data alone, what can you conclude about the roles of environment and genetics in hearing loss?

Drug X was developed to reduce blurred vision in healthy patients, but the effectiveness had not been tested on those suffering from multiple sclerosis. A study was conducted to determine if Drug X is effective at reducing blurry vision in multiple sclerosis patients. To be considered effective, a drug must reduce blurred vision by more than 30% in patients. Researchers predicted that a 20 mg dose of the drug would be effective for treating blurred vision in multiple sclerosis patients by reducing blurred vision by more than 30%. Drug X was administered to groups of multiple sclerosis patients at three doses (10 mg/day, 20 mg/day, 30 mg/day) for three weeks. A fourth group of patients was given a placebo containing no drug X for the same length of time. Vision clarity was measured for each patient before and after the three-week period using a standard…arrow_forward
