- magnetic crystals
- polar bonds

Q: Answer the following question given this paragraph: Longer chains of monosaccharides are referred to as polysaccharides . Starch, glycogen, and cellulose are three extremely common polysaccharides made entirely out of glucose molecules. The differences lie in the types of bonds between the glucose units and the extent of branching in the carbohydrate chain. Starch is found in plants and is consumed as part of our diet. Glycogen is made by the body and is a storage form of glucose for when the cells need extra energy. Cellulose is another long-chain polysaccharide found in plants. Unlike starch and glycogen, the human body cannot break cellulose down into molecules of glucose. Although cellulose does not have any nutritional value in terms of calories, it is a major component of dietary fiber, which has other digestive benefits. Q: What is the term for longer chains of monosaccharides ? A:
Answer: polysaccharides

Problem:OPTIONS:
- physiological succession
- continuous succession
- environmental succession
- ecological succession

Answer the following question given this paragraph: Imagine walking in the forest in Figure below . The towering trees have been growing here for hundreds of years. It may seem as though the forest has been there forever. But no ecosystem is truly static. The numbers and types of species in most ecosystems change to some degree through time. This is called ecological succession. Important cases of ecological succession are primary succession and secondary succession. Q: The numbers and types of species in most ecosystems change to some degree through time and this is called? A:
****
A: ecological succession

Answer the following question given this paragraph: Partly movable joints allow only a little movement. Your backbone has partly movable joints between the vertebrae ( Figure below ). Q: Are the joints between the vertebrae contained in your backbone fully movable, partially movable, or unmovable? A:
OPTIONS:
- none of these
- unmovable
- fully movable
- partially movable
partially movable

Answer the following question given this paragraph: Each particular organism contains many protein molecules that are specific to that organism. The particular base sequence of DNA is responsible for the production of all of the different proteins that are present in each and every living thing that has ever inhabited the Earth. How does that work? Cells use the unique sequence of DNA bases to decide which proteins to synthesize. A gene is a segment of DNA that carries a code for making a specific polypeptide chain. The cell essentially decodes the DNA in order to make whatever peptides and proteins are needed by that organism. Q: What is a segment of dna that carries a code for making a specific polypeptide chain called? A:
OPTIONS:
- a protein
- nucleotide
- amino acid
- a gene

Answer: a gene

input with options: Answer the following question given this paragraph: Today, evolution is still questioned by some people. Often, people who disagree with the theory of evolution do not really understand it. For example, some people think that the theory of evolution explains how life on Earth first began. In fact, the theory explains only how life changed after it first appeared. Some people think the theory of evolution means that humans evolved from modern apes. In fact, the theory suggests humans and modern apes have a common ancestor that lived several million years ago. These and other misconceptions about evolution contribute to the controversy that still surrounds this fundamental principle of biology. Q: Misconceptions about what theory contribute to the controversy that still surrounds this fundamental principle of biology? A:
OPTIONS:
- darwin on evolution
- brain of evolution
- cycle of evolution
- theory of evolution
output:
theory of evolution
