A living organism is defined by the presence of one or more cells that exhibit characteristics of life, such as metabolism, growth, and response to stimuli. How do monosaccharides contribute to larger carbohydrate structures? Monosaccharides serve as the building blocks for larger carbohydrates like disaccharides and polysaccharides through glycosidic bonds. What structura...

Bio 112 Exam 1 Questions and Answers Already Passed What is the role of transcription factors in gene regulation? Transcription factors are proteins that bind to specific DNA sequences to promote or inhibit the transcription of genes. How do lipids contribute to the structure of cell membranes? Lipids, particularly phospholipids, form a bilayer in cell membranes that provides barriers for cell compartmentalization and regulates permeability. What is the significance of the pH sca...

Honors Biology: Unit 2 Test Questions with Certified Solutions What is the role of the cytoskeleton in the cell? The cytoskeleton provides structural support, helps maintain cell shape, and facilitates movement of materials within the cell. How do plant cells differ from animal cells in terms of organelles? Plant cells have chloroplasts and a large central vacuole, while animal cells do not. Animal cells have lysosomes, which are less common in plant cells. What is the function...

Honors Biology EOC Practice Questions with Verified Solutions How do transport proteins assist in moving molecules across the cell membrane? Transport proteins facilitate the movement of molecules across the cell membrane by providing specific pathways for substances to enter or exit the cell. What is the role of the Golgi apparatus in a cell? The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles. How do the two stag...

Honors Biology Unit 4 Questions and Answers Already Passed What is the primary function of the endoplasmic reticulum (ER) in cells? The ER synthesizes and transports proteins and lipids within the cell. How do vacuoles contribute to cell function? Vacuoles store nutrients, waste products, and help maintain turgor pressure in plant cells. What role do mitochondria play in energy production? Mitochondria generate ATP through the process of oxidative phosphorylation. What is ...

Pancreas and Type 1 diabetes - Answer- The pancreas is the organ that produces insulin, and it plays a major role in regulating blood glucose levels. Type 1 diabetes occurs when the pancreas does not make enough or any insulin. How does insulin work in diabetes? - Answer- Insulin pumps are small, computerized devices that mimic the way the human pancreas works by delivering small doses of short acting insulin continuously (basal rate). The device also is used to deliver variable amounts of in...

Honors Biology Unit 2 Test Questions and Answers Graded A+ What is the significance of the fluid mosaic model of the cell membrane? The fluid mosaic model describes the cell membrane as a dynamic structure with proteins and lipids moving freely within a fluid bilayer, which helps maintain its flexibility and functionality. What role do centrioles play in cell division? Centrioles help organize microtubules during cell division, facilitating the separation of chromosomes. How d...
