input: OPTIONS:
- muscles
- molecules
- proteins
- tissues Now, answer this question: Answer the following question given this paragraph: The human body is organized at different levels, starting with the cell. Cells are organized into tissues, and tissues form organs. Organs are organized into organ systems such as the skeletal and muscular systems. Q: What structure of the body falls between cells and organs in complexity? A:
A:
output: tissues

Answer the following question given this paragraph: The Cell Wall The cytoplasm of prokaryotic cells has a high concentration of dissolved solutes. Therefore, the osmotic pressure within the cell is relatively high. The cell wall is a protective layer that surrounds some cells and gives them shape and rigidity. It is located outside the cell membrane and prevents osmotic lysis (bursting due to increasing volume). The chemical composition of the cell walls varies between archaea and bacteria, and also varies between bacterial species. Bacterial cell walls contain peptidoglycan, composed of polysaccharide chains that are cross-linked by unusual peptides containing both L- and D-amino acids including D-glutamic acid and D-alanine. Proteins normally have only L-amino acids; as a consequence, many of our antibiotics work by mimicking D-amino acids and therefore have specific effects on bacterial cell wall development. There are more than 100 different forms of peptidoglycan. S-layer (surface layer) proteins are also present on the outside of cell walls of both archaea and bacteria. Bacteria are divided into two major groups: Gram positive and Gram negative, based on their reaction to Gram staining. Note that all Gram-positive bacteria belong to one phylum; bacteria in the other phyla (Proteobacteria, Chlamydias, Spirochetes, Cyanobacteria, and others) are Gram-negative. The Gram staining method is named after its inventor, Danish scientist Hans Christian Gram (18531938). The different bacterial responses to the staining procedure are ultimately due to cell wall structure. Gram-positive organisms typically lack the outer membrane found in Gram-negative organisms (Figure 22.15). Up to 90 percent of the cell wall in Gram-positive bacteria is composed of peptidoglycan, and most of the rest is composed of acidic substances called teichoic acids. Teichoic acids may be covalently linked to lipids in the plasma membrane to form lipoteichoic acids. Lipoteichoic acids anchor the cell wall to the cell membrane. Gram-negative bacteria have a relatively thin cell wall composed... Q: The cytoplasm of prokaryotic cells has a high concentration of dissolved solutes. therefore, the osmotic pressure within the cell is what? A:

OPTIONS:
- relatively normal
- relatively low
- relative
- relatively high

Answer: relatively high

Problem: OPTIONS:
- hypoxia
- myopia
- micropsia
- hyperopia
Q: Answer the following question given this paragraph: Hyperopia is commonly called farsightedness. People with hyperopia can see distant objects clearly, but nearby objects appear blurry. Hyperopia occurs when images focus in back of the retina because the eyeball is too short. This vision problem can be corrected with convex lenses, which curve outward. The lenses focus images correctly on the retina. Q: What is the scientific term for farsightedness? A:
Answer: hyperopia

Problem:OPTIONS:
- soil
- ash
- sand
- sediment

Answer the following question given this paragraph: Most fossils form when a dead organism is buried in sediment. Layers of sediment slowly build up. The sediment is buried and turns into sedimentary rock. The remains inside the rock also turn to rock. The remains are replaced by minerals. The remains literally turn to stone. Fossilization is illustrated in Figure below . Q: Most fossils form when a dead organism is buried in what? A:
****
A: sediment

Answer the following question given this paragraph: Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Q: Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a? A:
OPTIONS:
- cell wall
- chloroplast
- brain
- plasma membrane
plasma membrane

Answer the following question given this paragraph: The rise in greenhouse gases due to human actions is too much of a good thing. It increases the greenhouse effect and causes Earth's average temperature to rise. Rising global temperatures, in turn, are melting polar ice caps and glaciers. Figure below shows how much smaller the Arctic ice cap was in 2012 than it was in 1984. With more liquid water on Earth's surface, sea levels are rising. Q: The rise in greenhouse gases has what effect on the temperature of earth? A:
OPTIONS:
- no effect
- more moderate
- it drops
- it increases

Answer:
it increases
