Answer:
The correct option is c. The sensors for the arterial baroreceptor reflex are located in carotid sinus and aortic arch.
Explanation:
Baroreceptors are primary sensors (or mechanosensitive nerve endings) that detect distention in vascular walls and are stimulated by mechanical deformations during blood vessel stretching. They are located in the carotid sinus and the aortic arch. The stretching the vessel walls at any of these locations causes vasodilation and bradycardia. The baroreceptors detect the stretching of the vessels due to changes in blood pressure, through them a more efficient control of blood pressure is achieved.
C. is your correct answer.
The invention of the electron microscope opened up many doors for biologists as it helped them to view and learn the appearance of cells and their sub-cellular structures
<h3>What is an electron microscope?</h3>
Electron microscope are microscopes which helps biologists to view the appearances of cells of organisms which cannot be seen with our nak -ed eyes.
Generally, electron microscopes:
- Uses a beam of accelerated electrons as its source of illumination
- Helps in obtaining high resolution images of biological and non-biological specimens.
- It is also used in biomedical research
In conclusion, electron microscope helps biologists to view, learn and to also understand the appearance of cells and their sub-cellular structures

Answer:
d. Skinner box
Explanation:
Skinner box provides an experimental condition that is used for examining natural flow of the behavior. It is also known with the other name as Operant conditioning chamber. It is a small chamber in which the animals for research are kept. Within the chamber there is a lever or key that the organisms under research can operate in order to get food or water in the chamber. An electronic equipment is connected to the chamber which records the activities of animals on keys or lever.
