What is the difference between animal cells and plant cells? What is aquaporin?
The difference between animal cell and plants cells is that in plants cell has chloroplast and rigid like called cell wall. And animal cells have centrioles, with no cell wall. Also, the animal cell shape is round and the plant cell has a rectangle shape. The aquaporin is the protein channels in the cell membrane is responsible for the transport water through osmosis. Because cell membranes have both properties of the hydrophobic mean cannot dissolve in water and hydrophilic properties mean dissolve in water. Therefore, it needs a separate channel to have a hydrophilic property to transport water from in and out of the membrane.

At the ice-cream vending machine, an ice-cream sandwich costs $2.00, Marino Italian ice costs $1.50. The costs of a total 200 ice-cream sandwich and Marino Italian ice was $356.50. How much ice-cream was sold?
Step 1: Define Variables Let "s" be the number of ice-cream sandwich was sold. Let "i" be the number of Marino Italian ice sold. Step 2: Write systems of equations: 2.00s + 1.50i = 346.50 s + i = 200 Step 3: Solve the Systems of Equations: 2.00s + 1.50i = 346.50 (100) * Multiply 100 to the first equation. s + i = 200 * Multiply the second equation with -150 200s + 150i = 34,650 using the elimination method to eliminate -150 (s + i = 200) one variable and solve for another. _____________________ * Solve for the varible "i" and it leads s= 93. 200s + 150i = 34,650 - 150s -150i = -30,000 __________________ 50s = 4,650 50s/50 = 4,650/50 s = 93 Step 4: Substitute the Value s + i = 200 93 + i = 200 -93 = -93 __________ i = 107 Step 5: Check Your Answer 2.00s + 1.50i = 346.50 s + i = 200 2.00(93) + 1.50 (107) = 346.50 93 + 107 = 200 186 + 160.5 = 346.50 ____________ 346.50 = 346.50 200 = 200
