Which of the following is true of unsaturated fats?
(a) they are more common in animals than in plants.
(b) they have double bonds in their fatty acid chains.
(c) they generally solidify at room temperature.
(d) they contain more hydrogen than do saturated fats having the same number of carbon atoms.

The correct answer is option B.

Explanation:

The fatty acids are differentiated into unsaturated and saturated fatty acids on the basis of the double bonds they contain in their composition. If a fatty acid contains no double bond, it is known as saturated fatty acid, on the other hand, the double bond constituting fatty acids are known as unsaturated fatty acids.  

These kinds of fatty acids are abundantly found in animals. An unsaturated fatty acid contains one or more double bonds in their composition. At room temperature, the saturated fatty acids are found in solid form, while unsaturated fatty acids come in liquid form. The number of hydrogen atoms is found more in a saturated fatty acid, in comparison to an unsaturated fatty acid.  

as a camel goes without food, its hump begins to shrink. its fur prevents the camel from sweating too much.camels store fat in their humps, not water.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
