Concept explainers
(a)
To classify:
‘A surge of epinephrine initiates a flight response in a gazelle’ as either a proximate or an ultimate cause of the behavior.
Concept introduction:
Animal behavior is a very broad topic that covers everything that is done by animals. It includes movement and other activities that are performed by the animals. It is such a topic that helps to connect the two streams ecology and animal physiology to a great extent. In an animal behavior, there is involvement, and connection of many physiological systems and connections among the endocrine, muscular, nervous, reproductive and many other organ systems.
(b)
To classify:
‘Turtle uses Earth’s magnetic field lines as guides during migration’ either as a proximate or an ultimate cause of the behavior and for all proximate causes. Also, speculate about a possible ultimate cause of the behavior.

(c)
To classify:
The descriptions that ‘a small mammal ignores food sources that have low energy and that are difficult to obtain’ as either a proximate or an ultimate cause of the behavior and in case of proximate causes speculate about a possible ultimate cause of the behavior.

(d)
To classify:
The descriptions in which ‘a bird distracts its predator near its nest, which increases the chance of survival of the nestlings’ as either an ultimate or a proximate cause of the behavior and for all proximate causes give a possible cause of the behavior.

- Anwser these Discussion Questions: Part One Why were the plants kept in the dark prior to the experiment? Why is this important? Why is it important to boil the leaf? Explain why it was necessary to use boiling alcohol? What is the purpose of the iodine? Part Two What was the purpose of keeping the leaf in the dark and then covering it with a cardboard cut-out? What conclusions can you draw from this part of the lab? Part Three 7. In this experiment what was the purpose of adding the soda lime? 8. Why was a sealed bag placed around each plant? 9. What happened in the control plants? 10. What was the result on photosynthesis? Part Four 11. Why was a variegated leaf used in this experiment? !2. What conclusions can you draw about starch production in a variegated leaf?arrow_forwardHow did the color differences between the two bacterial species you used in this experiment help you determine if the streak plate method you performed was successful?arrow_forwardseries of two-point crosses were carried out among six loci (a, b, c, d, e and f), producing the following recombination frequencies. According to the data below, the genes can be placed into how many different linkage groups?
