Answer:
C is surely the answer
C. Disrupting intermediate filaments will result in cells that are more susceptible to mechanical forces. In the case of the keratinocytes, disrupting keratin, a key IF in these cells, would result in very fragile cells. Less force would need to be applied using the magnetic beads to damage them or change their shape.

Answer:
12. Protein 13. Atmosphere 14. Nitrogen fixation 15. Plants 16. Consumers 17. Urinate 18. Decay 19. Decomposers 20. Ammonia 21. Denitrification
Explanation:
<em>12. Protein</em>
Nitrogen is essential to organisms. It is the main constituent of amino acids, which is the building blocks of protein in organisms.
<em>13. Atmosphere</em>
Nitrogen occurs naturally as gas in the earth’s atmosphere, accounts for about 78% of gases found in the atmosphere. This gaseous Nitrogen which is inert cannot be accessed by plants and animals for use.
<em>14. Nitrogen fixation</em>
For plants to be able to use the gaseous Nitrogen in the atmosphere, Nitrogen fixation has to take place. It involves the turning of gaseous Nitrogen in the atmosphere into ammonia. Nitrogen atoms is combined with Hydrogen atoms by enzyme called “nitrogenase”. This enzyme is present in nitrogen-fixing bacteria.
<em>15. Plants
</em>
Nitrogen enters the food web when plants assimilate nitrogen compounds from the soil to form nucleotides, amino acids, and other important chemicals in life.
<em>16. Consumers
</em>
Consumers are mainly animals that feed on plants in an ecological food web in other to be able to use the amino and nucleic acids formed from Nitrogen as a major component. Consumers can be categorized as primary, secondary, and tertiary consumers.
<em>17. Urinate
</em>
Nitrogen is very much concentrated in the urine of animals and also in their faeces. As animals urinate, Nitrogen is being returned to the soil.
<em>18. Decay
</em>
Decay starts, as organisms die. The organisms start decomposing.
<em>19. Decomposers
</em>
Decomposers are the bacteria in the soil that break down the nucleic and amino acids in dead organisms into nitrates and ammonia through a process called ammonification
<em>20. Ammonia
</em>
This is the end result of the decomposition of dead organisms by decomposers
<em>21. Denitrification
</em>
Compounds of nitrogen are turned back into gaseous nitrogen by anaerobic bacteria. This prevents
<u>A 22-year-old patient with a history of iv drug abuse arrives at the clinic complaining of fever, night sweats, and weight loss. the physician suspects </u><u>acquired immune deficiency syndrome</u><u> an infectious disease caused by the human immunodeficiency virus.</u>
Acquired immune deficiency syndrome or AIDS is a disease caused by the human immunodeficiency virus or HIV wherein it attacks the body's immune system mainly the lymphocytes, specifically the helper T-cells which mainly promotes the differentiation of B cells into plasma cells. With a low helper T-cell count, there will be increased risk for other infectious diseases such as pneumonia and tuberculosis.
<u>A patient is diagnosed with heart failure. during assessment, the patient's feet show an abnormal accumulation of fluid, a condition known as </u><u>edema</u><u>. </u>
Edema is the accumulation of fluid to the interstitial space. In a patient with heart failure, there is edema of the feet as a result of increased filtration of the plasma due to the increased capillary hydrostatic pressure brought about by the pooling of blood to the systemic circulation as a result of right-sided heart failure. In left sided heart failure, pooling of blood is in the pulmonary circulation causing pulmonary edema.
<u>Brittany E., a college freshman, tells her roommate that she has a sore throat, tiredness, fever, and swollen neck glands. Brittany's roommate encourages her to go to the college infirmary, where the nurse suspects </u><u>infectious mononucleosis</u><u>, an acute infection caused by the Epstein-Barr virus.</u>
Infectious mononucleosis is a diseases characterized by sore throat, fatigue, fever, and prominent cervical lymphadenopathy caused by Epstein-Barr virus or EBV. Infectious mononucleosis is common among people in the teenage group as this is mostly transmitted by kissing (hence called as the kissing disease). EBV infection also predisposes the patient into developing nasopharyngeal carcinoma, especially if untreated.
<u>A 73-year-old patient is admitted from a longterm care facility with fever and chills. blood cultures identify the presence of Escherichia coli. the physician diagnoses </u><u>septicemia</u><u>, also known as a blood infection.</u>
Septicemia is the systemic inflammatory response with consequential tissue damage in the background of severe systemic infection, especially in the blood. The presence of E. coli in blood cultures confirms the presence of bacteria in the blood causing sepsis. Sepsis can proceed to septic shock, with signs such as low blood pressure and cold, clammy extremities, which can lead to death if untreated.
<u>Kate S. is brought to the emergency department by her husband because she has had a fever for the past 3 days. blood specimens are drawn and her white blood cell count is elevated. the physician asks the laboratory staff to perform a(n) differential count to determine the distribution of white blood cells.</u>
A differential count is a component of complete blood count wherein it aims to determine the distribution of different kinds of white blood cells. The different kinds of white blood cells are neutrophils, lymphocytes, eosinophils, basophils, and monocytes. The percentages of differential count will determine whether the infection is acute/bacterial (neutrophil predominant), chronic/viral (lymphocyte predominant), allergic (presence of eosinophils and/or basophils), etc.
