A 6-year-old child ate a peanut butter sandwich at snack time in school. Five minutes later, her
throat became swollen and she collapsed. This
allergic reaction occurred because her body
(1) recognized an antigen in peanut butter and
produced antibiotics against it
(2) digested the white blood cells that can
recognize an antigen in peanut butter
(3) did not recognize an antigen in peanut
butter and could not produce antibodies
(4) recognized an antigen in peanut butter and
produced an immune response
A client who uses portable home oxygen states, "i still like to smoke cigarettes every now and then." what is the appropriate nursing response?
Correct answer: you should never smoke when oxygen is in use.
Explanation: Although oxygen is a gas which doesn't catch fire. But an environment rich in oxygen can easily cause burning of other substances which catch fire quickly. Therefore, doctors suggest that the patient should put off the oxygen mask away for few minutes while he/she is smoking.
Also, since the patients on oxygen already have some sort of respiratory or heart diseases, such patients can worsen the condition by smoking.
A nurse is teaching a client how acupressure works to relieve pain. which explanation would the nurse most likely use?
Acupressure is considered as the acupuncture in the absence of the needles. In this the use of fingertips, that is, the manual pressure is done on the particular points of the body.

what is the most important factor that holds a gene pool of a species together and prevents speciation?
The correct answer is Gene Flow.
Gene flow which is also known as allele flow or gene migration is the transference of genetic distinction from one population to the other. If the degree of gene flow is high enough, then it means that two populations are said to have equal genetic variety and a single population.
Bears typically eat a mixture of plants and animal food sources. When a bear is unable to find meat, it will have a much lower fat intake, which will limit its supply of (1)___. This would directly affect the (2)___ and normal body functions. 1. amino acids, essential fatty acids, or glucose.
2. cell membrane, muscles, or bones.
Fats are complex biomolecules, made up of long hydrocarbon chains. For bears, meat and fishes are main source of fats. Fats provide essential fatty acids to the body that play various biological roles, such as in energy storage functioning of bones, and insulating vital organs.
When a bear cannot find meat, it will show a much lower intake of fats. Lower fat intake would lead to limit the supply of essential fatty acids as these molecules are produced by the digestion of fats.
Essential fatty acids molecules help in proper growth and functioning of bones, as they are necessary for proper calcium metabolism. So, limited supply of essential fatty acids will directly affect the bones and normal body functions.
Thus, the correct options are 1). essential fatty acids and 2). bones.
