After you graduate, while looking for a job, you come across an advertisement for a recent graduate who has knowledge of biospheres. You have no problems with applying for this position because: Biospheres are another name for cells. They consist of cell membranes, nuclei, proteins and the other organelles within a cell. Being a major are well versed in this area. Biospheres are the spherical structures that when assembled form atoms and molecules. Each proton, neutron, electron is considered a biosphere. Being a biology major you are well versed in this area. \"Biosphere\" can be defined as the ecological system of different species (Mus musculus, Rattus norvegicus, Homo sapiens, etc.) that are found within earth. You are glad that you took Ecology during your 4 years and have closely followed the Mars mission. You can feel confident in working in this position. Since many organisms have varied physical shapes, \"biosphere\" is general term used to describe the organs, organs systems, organisms and populations of a specific species. Since these different biospheres may include a single species (Mus musculus, Rattus norvegicus, Homo sapiens, etc.) you will need to read more extensively about the biosphere that the position is advertising prior to applying for the job. None of the above. A 15-year old girl comes to the clinic, where she presents with cellulitis. The physician explains that cellulitis involves an infection and inflammation the integumentary system. Having successfully completed your Physiology Course at The University of Texas at El Paso, you know that the physician is referring to the system that normally: Coordinates body function through synthesis and release of regulatory adhesion proteins Exchanges oxygen and carbon dioxide between the internal and external environments. Maintains water and solutes in the internal environment and is also responsible for waste removal. Protects a host from its external environment Transports materials between all cells of the body It is said that under normal conditions the body reaches homeostasis, which is the same as saying that the body is: At a dynamic steady state At a state of equilibrium Normally functions with diploid, homologous pairs of chromosomes. Under a condition where the host is in its natural habitat All of the above You are asked to stop by the pharmacy to pick up a bag of intravenous fluid. The composition of the fluid must isotonic. You pick up a bag of water that contains 5% dexstrose mixed with: 150 mM Amonium chloride; 5mM potassium sulfate 100 mM Calcium chloride; 50mM Sodium bicarbonate 150mM Potassium chloride 150mM Sodium chloride Any of the above solutions would be fine since they contain 5% dextrose

Solution

1.c.from the options you can clearly know that biosphere is zone of life on Earth where all living organisms interdepent on each other. Being biology student you will be having the idea of what biosphere consist of.

2.d. Because integumentary system protect the body from external abrasions, water loss and includes skin and its appendages like hair, nails etc.

3.a Dynamic steady state. Homeostasis is the maintenance of equilibrium within an internal environment in response to external changes. The term comes from the Greek words \"homeo,\" which means \"similar,\" and \"stasis,\" which means \"stable.\"

4.d. 150mM sodium chloride in 5%Dextrose is isotonic intravenous fluid.
