| Question | Answer |
|---|---|
| Define cell. | The smallest unit that can perform all life processes; cells are covered by a membrane and have DNA and cytoplasm. |
| Define stimulus. | Anything that causes a reaction or change in an organism or any part of an organism. |
| Define homeostasis. | The maintenance of a constant internal state in a changing environment. |
| Define sexual reproduction. | Reproduction in which the sex cells from two parents unite, producing offspring that share traits from both parents. |
| Define asexual reproduction. | Reproduction that does not involve the union of sex cells and in which one parent produces offspring identical to itself. |
| Define heredity. | The passing of genetic traits from parent to offspring. |
| Define metabolism. | The sum of all chemical processes that occur in an organism. |
| Define producer. | An organism that can make its own food by using energy from its surroundings. |
| Define consumer. | An organism that eats other organisms or organic matter. |
| Define decomposer. | An organism that gets energy by breaking down the remains of dead organisms or animal wastes and consuming or absorbing the nutrients. |
| Define protein. | A molecule that is made up of amino acids and is needed to build and repair body structures and to regulate processes in the body. |
| Define carbohydrate. | A class of energy-giving nutrients that includes sugars, starches, and fiber; contains carbon, hydrogen, and oxygen. |
| Define lipid. | A type of biochemical that does not dissolve in water; fats and steroids are lipids. |
| Define phospholipid. | A lipid that contains phosphorus and that is a structural component in cell membranes. |
| Define ATP. | Adenosine triphosphate, a molecule that acts as the main energy source for cell processes. |
| Define nucleic acid. | A molecule made up of subunits called nucleotides. |
| What are the six characteristics of all living things? | Living things have cells, sense and respond to change, reproduce, have DNA, and grow and develop. |
| What are the six elements that are key to life? | Sulfur, phosphorous,nitrogen, oxygen, carbon, hydrogen |
| What is one way you respond to stimulus? | Examples: squinting, sweating, shivering |
| Name the two types of carbs. | Simple and complex |
| Which portion of the phospholipid is attracted to water? | Phosphorous portion |
| What do nucleic acids make? | Protein |
| How are carbohydrates and lipids used for energy? | They are transferred to ATP. |
| What are two examples of proteins? | Enzymes and Hemoglobin |
| What are the five chemical components of cells? | Proteins, Carbohydrates, Lipids, ATP, Nucleic Acid |
| Give an example of a simple carbohydrate. | Table sugar. |
| Give an example of a complex carbohydrate. | Potatos, pasta |
| Could organisms survive if the air was only oxygen? | No, plants need carbon dioxide, and we would die without plants. |
| Are decomposers also consumers? | Yes, decomposers break down or consume dead organisms or organic waste |
| What is the difference between growth and development? | Growth is a change is size, development is a change in form. |
