Which organelle performs autophagy? a) Proteasome b) cytoskeleton c) Ribosome d) Lysosome - correct answer Lysosome Lysosomes can digest worn-out organelles and release the by products in the cytoplasm. (autophagy=self digestion) -Proteasome degrades malfunctioning/ misfolded proteins to peptides -Cytoskeleton maintains the shape and organization of cell contents -ribosome is large and translates mRNA to proteins Fe+ O2----->Fe203 a) Fe +o2-----> 2Fe2O3 b) Fe+3O2-----&g...

Which of the following cell types provides a waterproofing function for the outer layers of skin? A. Melanocytes B. Keratinocytes C. Merkel cells D. Langerhans cells - correct answer B. Keratinocytes Keratinocytes contain the protein keratin. They are produced in the epidermis and migrate upwards. The tight junctions between cells prevent water entry. They eventually form a layer of dead cells on the skin surface, which produces a waterproofing effect. A person is suddenly frightened...

The price of a 20" television changed from $450 to $400. Find the percentage change in price. A. -10% B. -11% C. -13% D. -15% - correct answer Correct answer: -11% Change in price: 450 - 400 = 50 To determine the percentage change, divide the change in price by the initial price: 50 = 0.1111 450 Multiply by 100 to determine the percentage: 0.1111 × 100 = 11.11% Because the price decreased, the change in price is negative: -11.11%, or about -11% Which of the ...
