Answer:
Sexual competition often occurs within complex social environments where male displays can be received by potential mates, rivals, or both at once. In brown-headed cowbirds’ breeding flocks, for example, multiple males sometimes vie directly for a single female’s attention; at other times males have opportunities to sing to females without interference. It was tested whether cowbirds vary the intensity of their signalling across contexts like these. The songs were recorded from males courting females both with and without a male competitor in sight. The recordings were now played to solitary, naïve females in sound attenuation chambers, and also to a naïve aviary-housed flock. The songs males had produced when they could see their competitors were more attractive, eliciting more copulatory postures from naïve females and more approaches from birds in the flock.
Explanation:
The correct answer is (c) They show which part of the brain are involved in specific activities.
The functional magnetic resonance imaging is used to measure the activity of brain by the detecting the change in the blood flow. This is done because the cerebral blood flow is associated with the neuronal activation. The functional area of brain has a higher blood flow that can be observed in functional MRI. The commercial application of functional magnetic resonance imaging is used in lie detectors. This technique is also used in research world and in some clinical trails. Physicians use this technique to see how risky a brain surgery can be. It is also used to learn how a normal, diseased, or injured brain functions.
The complete question is as follows:
A group of 100 bomb blast victims were admitted to the hospital within an hour of the event. How should the hospital management use this information?
A
. Arrange surgery facilities for 50 victims.
B
. Arrange beds for at least 20 more victims.
C
. Prepare staff to treat 100 more clients.
D. Shift the 100 existing clients to other hospitals.
Answer:
The correct answer is option C. prepare staff to treat 100 more.
Explanation:
Management of hospital can predict the total number of the victims of a particular disaster by the number of the victims come who come in very first hour to the disaster.
One can predict the double the number of the patient of the victims that arrive the first hour. So by the assuming that 100 victims more might come so management should prepare more staff for the more 100 victims.
Thus, the correct answer is - option C.
