What I Know True or False. Read each statement carefully. Identify whether the statement is true or false. Write your answer on
a separate sheet of paper. 1. Carbohydrates contain carbon. 2. Meat contains protein. 3. Lipids are soluble in water. 4. Proteins are made up of nucleotides. 5. DNA is a nucleic acid. 6. Sucrose is a disaccharide. 7. Starch is composed of many glucose units. 8. Fructose is also known as blood sugar. 9. Keratin is easily dissolved in water. 10. Proteins are made up of nucleotides. 11. The heme group of hemoglobion contains iron. 12. A nucleotide has three parts: nitrogenous base, sugar, and phosphate group. 13. DNA has a double-helix structure. 14. Triglyceride is a protein. 15. Generally, unsaturated fatty acids remain solid at room temperature,
1) TRUE - Carbohydrates are composed of carbon, hydrogen, and oxygen and have a general formula that approximates CH2O.
2) TRUE - Animal proteins, such as meat, eggs, and milk, are complete proteins, meaning they provide all of the essential amino acids our body needs.
3) FALSE - If talking about neutral lipids, they are soluble in organic solvents and are not soluble in water.
4) TRUE - Each sequence of three nucleotides, called a codon, usually codes for one particular amino acid.
5) TRUE -DNA and RNA are both nucleic acids
6) TRUE - Sucrose is a disaccharide made up of 50% glucose and 50% fructose.
7) TRUE - It has numerous glucose units
8) TRUE -Some doctors may call that
9) FALSE - Keratin is completely insoluble in cold or hot water.
10) TRUE - Each sequence of three nucleotides, called a codon, usually codes for one particular amino acid.
11) TRUE - Each heme group contains one iron atom, that can bind one oxygen molecule through ion-induced dipole forces.
12) TRUE - It has three parts
13) TRUE - DNA has a double-helix structure
14) FALSE - Triglycerides are lipid
15) FALSE - It’s debunked, the molecular structure of unsaturated fats makes them liquid at room temperature. Their fat molecules do not stack easily, so they cannot form a solid at this temperature.
It’s A liquid to a solid because if it’s a liquid they can move but not much and then it becomes a solid because they are packed closely together and are fixed in one position.
I do not think that it is the most reliable way to gain information since it is very hard to do and can be easily messed up. No, I don't think you can charge someone on only evidence from blood spatter, but if there was additional evidence I think that this would definitely help with the case but not on its own, since it doesn’t give you physical evidence about the suspect.
