Comparing and contrasting a compound light microscope, basically both operate by bouncing tiny particles or waves off of objects in order to make them visible. Electrons are smaller than light photons so we can see smaller objects clearly with electron microscopes. There are disadvantages though. First, color is a function of light wave frequency so we can't see electron micrographs in color. Color can be added artificially though by computer to differentiate structures, (think photoshop). Also, we cannot see electrons so we make them visible by bouncing them off a cathode ray screen similar to a TV set or computer monitor
The Great Barrier Reef is one of the most sought-after scuba diving spots in the entire world, with phenomenal coral beds that are flooded with light and sea life.
TRUE if the genetic component of a family history of osteoarthritis, rheumatoid arthritis, or ankylosing spondylitis is significant.
<h3>What are rheumatoid arthritis, ankylosing spondylitis, and osteoarthritis?</h3>
Ankylosing spondylitis (AS) and rheumatoid arthritis (RA) are two of the most prevalent rheumatic illnesses. The joint degradation and decline in physical fitness are caused by these chronic progressive inflammatory disorders. [1] Their symptomatology and etiology differ despite being closely related.
<h3>What aspects of a patient's condition might point to a higher risk of osteoarthritis?</h3>
Age: As people get older, their chance of having OA rises. Gender—After the age of 50, women are more likely than males to acquire OA. Obesity—Extra weight increases the strain on joints, especially those that bear the body's weight, including the hips and knees.

Ansywer: (C) The hypothalamus is located in each endocrine gland to help regulate functioning.
Explanation: Hypothalamus is located at the base of the brain lying below the thalamus (in the third cerebral ventricle).
Hypothalamus is connected to pituitary gland and both modulates transmission of stimuli. It also regulates internal functioning in response to external stimuli and other functions.
Thus, all the above options are correct EXCEPT “it is located in each endocrine gland to help regulate functioning”.
