Problem: OPTIONS:
- substructure
- history
- iteration
- phylogeny
Q: Answer the following question given this paragraph: Phylogeny is the evolutionary history of group of related organisms. It is represented by a phylogenetic tree that shows how species are related to each other through common ancestors. Q: What is the evolutionary history of group of related organisms A:
Answer: phylogeny

Problem:OPTIONS:
- scoliosis
- fibrosis
- arthritis
- atherosclerosis

Answer the following question given this paragraph: Atherosclerosis is a condition in which a material called plaque builds up inside arteries. Plaque consists of cell debris, cholesterol, and other substances. As plaque builds up in an artery, the artery narrows, as shown in Figure below . This reduces blood flow through the artery. Q: What is a condition in which a material called plaque builds up inside arteries? A:
****
A: atherosclerosis

OPTIONS:
- somatic meristem
- interior meristem
- algal meristem
- apical meristem
apical meristem

Answer the following question given this paragraph: Objects have the same velocity only if they are moving at the same speed and in the same direction. Objects moving at different speeds, in different directions, or both have different velocities. Q: Objects moving at different speeds, in different directions have different what? A:
OPTIONS:
- protons
- vibrations
- electrons
- velocities

Answer: velocities

Question: Answer the following question given this paragraph: ART CONNECTION QUESTIONS 1. Figure 5.7 On a hot, dry day, plants close their stomata to conserve water. What impact will this have on photosynthesis?. Q: On a hot, dry day, plants close their stomata to conserve what? A:
OPTIONS:
- sunlight

input: OPTIONS:
- replication reaction
- osmosis
- metabolism
- reabsorption Now, answer this question: Answer the following question given this paragraph: Flame Cells of Planaria and Nephridia of Worms As multi-cellular systems evolved to have organ systems that divided the metabolic needs of the body, individual organs evolved to perform the excretory function. Planaria are flatworms that live in fresh water. Their excretory system consists of two tubules connected to a highly branched duct system. The cells in the tubules are called flame cells (or protonephridia) because they have a cluster of cilia that looks like a flickering flame when viewed under the microscope, as illustrated in Figure 41.10a. The cilia propel waste matter down the tubules and out of the body through excretory pores that open on the body surface; cilia also draw water from the interstitial fluid, allowing for filtration. Any valuable metabolites are recovered by reabsorption. Flame cells are found in flatworms, including parasitic tapeworms and free-living planaria. They also maintain the organism's osmotic balance. Q: How are valuable metabolites recovered? A:
A:
output:
reabsorption
