The method used above involves the determination and comparison of the genes of the three species of finches. So, the answer is
<span>(3) Obtain molecular evidence from all three species and identify similarities.
</span><span>The genetic makeup of the three species will show different similarities that can be used to relate the evolution of the different species.</span>
Answer:
It would be difficult to recreate the exact conditions of the chemical release elsewhere.
Explanation:
Answer:
c) melatonin
Explanation:
Melatonin its a hormone formed by the pineal gland, which regulates an individual wake cycles and sleep. Jetlag alters the hormone function leading to an alteration with the body clock of the persom.
Jetlag is a sleep disorder common to those who travel swiftly over several time zones. It is not a permanent sleep disorder. Its due to the body's internal clock lacking sync with cues generated in a different time zone, Cues may be due to light exposure and how often the person eats.
A basic factor on ones internal clock is sunlight. It controls the regulation of melatonin which aid in synchronizing cells in the body.
Specific cells of the tissue at retina moves the light signals the thypothalamus.
At night, the hypothalamus signal to the pineal gland to produce melatonin. At daylight hours, the reverse is the case.
Answer:
The correct answer is: the group of 10 people that lifted the barbell with music is the control group.
Explanation:
The personal trainer made an experiment to test her hypothesis. When experiments are being made, is common to have a control group and an experimental group.
The control group is the one that is subjected to the usual conditions, the group that shows what normally happens. The experimental group is the opposite, this group is observed while it goes through an unusual condition that may impact how they perform in the task observed.
<u>The personal trainer thinks that playing music for her clients is of benefit to them, so we can assume that she always plays music during the workouts, which means that the control group is the one that is listening to music while lifting a barbell</u>. The group that worked out without music is the experimental group because they were the ones that performed that activity with a change in their normal environment.
