The geological conditions.
Answer:
The correct answer is option A. "The contents of blood come into closer contact with tissues in a closed system than an open system".
Explanation:
In a closed circulatory system, the blood has an specific path, circulating from arteries to veins and to smaller blood vessels throughout the body. This is in contrast with open circulatory systems at which the blood is not contained in arteries or veins but it suffuses the body. A closed circulatory system have many advantages over open circulatory system, however in a closed circulatory system the contents of blood are not into closer contact with tissues in than an open system. Actually, in an open circulatory system the blood is in closer contact with tissues.
Answer: Both the pupil will constrict in response to the light shown into the pupil.
Explanation:
The papillary response can be defined as a reflex that is generated in response to the intensity of light falling on eyes, which either dilates the pupil or constrict the pupil.
This reflex will constrict the pupil when light will be shown on eyes so that less light can enter the retinal ganglion cells of the retina.
Thus, in this way the papillary response of both eyes will be same and both the pupil will constrict.
Hence, both the pupil will constrict together in response to the light falling on right eye.
Answer:
100,000 years
Explanation:
A photon of light takes only eight minutes to get to the Earth from the surface of the Sun. But it can take 100,000 years from the core of the Sun to get to the surface. Where it bursts out and flies at the speed of light.
