You will not find a cell wall in which of these kinds of organisms?
a. plants
c. fungi
b. animals
d. all of the above

The best answer is b - animals.

A cell wall is defined as a rigid layer found outermost in plants and certain algae, bacteria and fungi. in animals, the cell wall is absent.

 In plants it is composed of cellulose, a type of structural polysaccharide which offers mechanical support allowing plants such as trees to grow up to great heights.

In fungi the cell wall is made of chitin, a polysaccharide composed of N - acetylglucosamine.  Chitin is also a major ingredient of the exoskeletons of arthropods and crustaceans.

answer: although many types of viruses can cause a common cold, rhinoviruses are the most common culprit. a cold virus enters your body through your mouth, eyes or nose. the virus can spread through droplets in the air when someone who is sick coughs, sneezes or talks. theres your answer

explanation:

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.
