Answer the following question given this paragraph: Bacteria come in many different shapes. Some of the most common shapes are bacilli (rods), cocci (spheres), and spirilli (spirals). Bacteria can be identified and classified by their shape. Q: Spirals, spheres, and rods are examples of what distinguishing property of bacteria? Choices: - function - color - organ - shape A:
shape
Answer the following question given this paragraph: Roots absorb water and minerals and transport them to stems. They also anchor and support a plant, and store food. A root system consists of primary and secondary roots. Each root is made of dermal, ground, and vascular tissues. Roots grow in length and width from primary and secondary meristem. Q: What system transports minerals and water in a plant? Choices: - leaves - stamen - flowers - roots A:
roots
Q: Answer the following question given this paragraph: Photosynthesis is the base of nearly all food chains on Earth. This is true of marine food chains, too. Q: What is the base of nearly all food chains on earth? Choices: - glycolysis - atherosclerosis - synthesis - photosynthesis A:
A: photosynthesis
Question: Answer the following question given this paragraph: The concentration of copper ions in the solution is effectively constant. This is because the electroplating process transfers metal from the anode to the cathode of the cell. Other metals commonly plated onto objects include chromium, gold, silver, and platinum. Q: The electroplating process transfers metal from the anode to which part of the cell? Choices: - plasma - electrode - atom tube - cathode A:
Answer: cathode

Answer the following question given this paragraph: Q: In mismatch repair, other enzymes remove and replace incorrectly paired nucleotides that have resulted from what? Choices: - typing errors - interaction errors - evolution errors - replication errors A:
**Answer**
replication errors
(Q).
Answer the following question given this paragraph: Buffers work well only for limited amounts of added strong acid or base. Once either solute is all reacted, the solution is no longer a buffer, and rapid changes in pH may occur. We say that a buffer has a certain capacity. Buffers that have more solute dissolved in them to start with have larger capacities, as might be expected. Human blood has a buffering system to minimize extreme changes in pH. One buffer in blood is based on the presence of HCO3 and H2CO3 [H2CO3 is another way to write CO2(aq)]. With this buffer present, even if some stomach acid were to find its way directly into the bloodstream, the change in the pH of blood would be minimal. Inside many of the body's cells, there is a buffering system based on phosphate ions. Q: Human blood has a buffering system to minimize extreme changes in what? Choices: - sodium level - calcium - ions - ph A:
(A).
ph
