A process that involves the movement of water A process that requires energy A process that occurs across a cell wall The movement of any molecule from high to low concentration ACTIVE TRANSPORT Question 16 5 / 5 points What is the name of the process by which a cell will uptake large molecules from the extracellular fluid? endocytosis active transport facilitated diffusion exocytosis EUKARYOTIC ORGANELLES Question 17 5 / 5 points What is the function of the peroxisome in the eukaryotic cell? protein synthesis organizing center of microtubules in animal cells oxidizes and breaks down fatty acids and amino acids storage and transport ATP production Question 18 5 / 5 points In what type of cells would you expect to find a large amount of smooth endoplasmic reticulum? brain liver intestinal muscle ANTIBIOTICS AND PROKARYOTIC CELLS Question 19 5 / 5 points You have a case of the common cold (which is caused by a virus). What would happen if you take antibiotics? you will get better you will get another viral infection nothing you will get worse Question 20 5 / 5 points Which is a plausible effect of taking oral antibiotics? the antibiotics could unintentionally kill good bacteria living in your intestines, leaving you more susceptible to infection by pathogenic bacteria the antibiotics could harm your own body cells. the antibiotics could interfere with your body’s own ability to produce antibiotics, and actually end up prolonging the infection. the antibiotics could destroy viruses that have infected your body [Show More]
