All of my 9th grade year vocabulary (Updated frequently)
| Term | Definition |
|---|---|
| Carbohydrate | It is a compound made up of carbon, Hydrogen, and Oxygen. It's function is to produces energy for living organisms. You can find it in: Pasta, Bread, Cereal, Candy and Jams. |
| Lipids (Fat) | It's a macro-molecule made form Carbon, and Hydrogen. It's function is to store energy, it's part of the cell membrane. You can find it in: Wax, Oils, and Fats. |
| Nucleic Acids (DNA/RNA) | It's made from nucleotides, it is a polymer. It's Function is to store and transmit genetic information. It is made up of Hydrogen, Oxygen, Nitrogen, Carbon and Phosphorus. |
| Proteins | Controls and regulates cell process, enzymes, aid's the bone and muscle development. It is made up of Nitrogen, Carbon, Hydrogen, and Oxygen. |
| Macro molecules | Smaller units or monomers join together to create polymers. There are four types of Polymer Macro molecules, Carbohydrate, Lipids, Nucleic Acids, and Proteins. |
| Solvent | Something that dissolves another substance. (Water is a universal Solvent) |
| Solute | The substance that is being dissolved (Like sugar being put into water) |
| Adhesion | The attraction between two molecules of different substances. |
| Cohesion | The attraction between two molecules of the same substance. |
| Mass | Mass is how much matter is in an object |
| Volume | Volume is the amount of space an object has in it |
| Pressure | Pressure is the amount of force pushing on another object |
| Density | Density is how compact the particles are |
| Convection | Convection transfers heat through things like, gas's, liquids, and soilds. |
| Asexual Reproduction | Form of reproduction, Does not involve meiosis or fertilization there is only one parent involved. |
| Sexual Reproduction | Production of offspring from 2 parents using Gametes (Sperm and Egg) They are given 1/2 of chromosomes from each parent. |
| Inheritance | The process of genetic transmission of characteristics from a parent or ancestor to an offspring. |
| Gene | The fundamental, physical, and functional unit of heredity. |
| Geno type | A set of genes in our DNA which is responsible for a particular trait. |
| Phenotype | The physical appearance of an organism as distinguished from it's genetic makeup. |
| Dominant Trait | A trait will appear in the offspring if one of the parents contributes it. Ex: A girl born with black hair like her mothers, her mothers gene is dominant. |
| Recessive Trait | Relating to the form of a gene that is not expressed as a trait in an individual unless two such genes are inherited, one from each parent. |
| Pedigree | A genetic representation of a family tree that diagrams inheritance of a trait or disease through several generations. |
| Genetic Engineering | The science of altering and cloning genes to produce a new trait in an organism or to make a biological substance, such as a protein or hormone. |
| Cloning | Is the process of producing similar populations of genetically identical individuals that occurs in nature when organisms such as bacteria, insects or plants reproduce asexually. |
| Bioethics | A field of study concerned with the ethics and philosophical implications of certain biological and medical procedures, technologies, and treatments, as organ transplants, genetic engineering, and care of the terminally ill. |
