| Term | Definition |
|---|---|
| Describe the homeostatic control mechanism? | Homeostasis relies on feedback systems, receptors, control centers, and effectors to detect changes and restore balance. Negative feedback maintains stability, while positive feedback expedites specific processes. |
| List one type of epithelial tissue and one function. | Simple Squamous Epithelium. Function: Facilitates diffusion and filtration processes, such as exchange of gas in alveoli of the lungs. |
| How do bonds attract another molecule to the other? | Molecules are drawn to each other by intermolecular forces, which differ from the chemical bonds, such as covalent or ionic bonds, that connect atoms within a molecule. |
| What is the difference between catabolism and Anabolism? | Catabolism involves breaking down molecules and releasing energy, while anabolism is about building molecules and using energy. |
| Describe the main function of the cell? | The main function of a cell is to act as the fundamental unit of life, executing vital processes essential for survival. In general, cells sustain life by performing all necessary biological functions. |
| what is organelle? List one function organelle. | An organelle is a unique structure within a cell that performs a specific function. One key role of organelle is energy production; for instance, mitochondria produce energy for the cell via cellular respiration. |
| Name three muscles tissue and their key difference? | Skeletal, cardiac, and smooth muscles differ in control (voluntary or involuntary), structure (striated or non-striated), and cell shape or nucleus number. |
| what are the functions and classification of connective tissues? | Functions include support, binding, protection, storage, transport, and immunity. Classification covers connective tissue proper, cartilage, bone, and blood. |
| Name and state locations of two involuntary muscles. | Cardiac muscle (heart wall), smooth muscle (walls of intestines) |
| The skull is made up of how many divisions? Give examples. | Two divisions: Cranium and Facial bones. An example of a facial bone is the Maxilla, while a cranium bone example is the Frontal bone. |
| what is chemical digestion? | chemical digestion is the process by which complex and large food molecules are broken down into simpler molecule by action of an enzymes for nutritional absorption. |
| what is referred to as chief cell. | Chief cell also known as zymogenic cell or peptic cell is a specialized type of cell found in the lining of the stomach within the gastric glands located in the mucosa of the stomach wall. |
