C. calcium, hydrogen, sodium, and potassium D. carbon, oxygen, magnesium, and zinc. E. carbon, sulfur, calcium, and potassium.Explanation / Answer
90. Option D is correct. A clumping (reaction between antigen to their corresponding antibody) reaction occurs, which is known as aglutination reaction. Since antigens are present on erythrocytes, known as erythrocyte aglutination.
91. Option B is correct. Electrolytes ionize when dissolved in water. For example NACl converts into Na+ and Cl- when dissolved in water.
92. Option E is correct. Eicosanoids are 20 carbon compounds which play a role in the response of tissues to injuries. For example prostaglandins (eicosanoids) releases against injuries which causes inflammation.
93.Option C is correct. Carbodioxide contains 2 atoms of oxygen bonded with one carbon atom and thus, this is compound and as we know all the compounds are molecules but not all the molecules are compunds therefore option C is correct.
94. Option B is correct. Human body has 60 % water and thus hydrogen and oxygen is most abundant. Also, protein is a major component of human body and thus, nitrogen and carbon are also abundant.
