Answer:
Consciousness is the awareness of INTERNAL and EXTERNAL stimuli; often described as a continuum ranging from full awareness to deep sleep.
Explanation:
Internal stimuli include pain, hunger, thirst while external stimuli include light, sound.
Variation of consciousness is seen in different physical states ranging from full alertness to deep sleep. This is controlled by the biological clock, the circadian rhythm.
Answer: chorionic villus sampling
Explanation:
CVS: A thin tube that is guided through the cervix. Is a type of prenatal diagnostic test to detect chromosomal problems that can result in genetic diseases and birth defects.
The answer is convergent plate boundaries. Convergent of two plates depends on the types of crust that are colliding. Convergence can take place between two slabs of continental lithosphere, two slabs of oceanic lithosphere or between one continental and one oceanic slab. Oftenly when two plates collide one or both are destroyed nd when oceanic crust converges with continental crust the denser oceanic plate plunges beneath the continental plate.
Exercise and reactions to exciting stimuli include increased activity in the sympathetic, and decreased activity in the parasympathetic divisions.

What is the sympathetic nervous system?</h3>
The autonomic nervous system includes the sympathetic nervous system. It might be referred to as the "automatic" nervous system because it controls many processes that we don't have to think about. This can affect a variety of bodily processes, such as the regulation of our heart rate, blood pressure, digestion, urination, and perspiration. For its role in reacting to risky or stressful conditions, the sympathetic nervous system is best known.
<h3>
What is the parasympathetic nervous system ?</h3>
One of the two functionally separate and perpetually active divisions of the autonomic nervous system is the parasympathetic nervous system (PNS) (ANS). It opposes the sympathetic nervous system, which is the other (SNS). In calm "rest and digest" situations, the parasympathetic nervous system predominates, whereas the sympathetic nervous system activates the "fight or flight" response in stressful circumstances. The major functions of the PNS are to regulate body processes like digestion and urine as well as to store energy for later use.
Hence, Option B is correct. Exercise and reactions to exciting stimuli include increased activity in the sympathetic, and decreased activity in the parasympathetic divisions.
