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 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 ...

Honors Biology Semester 2 Final Exam with Complete Solutions What is the role of helicase in DNA replication? Helicase unwinds the DNA double helix by breaking hydrogen bonds between base pairs, allowing replication to begin. How does complementary base pairing ensure accuracy during DNA replication? Complementary base pairing (A with T, C with G) ensures that each new strand is an exact copy of the original template. What is a codon, and how is it related to DNA? A codon is ...

Honors Biology – Plants Questions and Answers Graded A+ What is the primary function of roots in plants? Roots anchor the plant and absorb water and nutrients from the soil. What is the role of chlorophyll in photosynthesis? Chlorophyll absorbs light energy, which is used to convert carbon dioxide and water into glucose. How do stomata regulate gas exchange in plants? Stomata open and close to allow the exchange of oxygen, carbon dioxide, and water vapor between the plant a...

Honors Biology Elephants Questions and Answers 100% Pass What is the primary diet of African elephants? African elephants primarily eat grasses, leaves, bark, and fruits. How do elephants use their trunks? Elephants use their trunks for breathing, grabbing objects, drinking water, and communicating. What role do elephants play in their ecosystem? Elephants act as keystone species, helping to shape their environment by creating pathways and dispersing seeds. How do elephant...

Honors Biology Semester 1 Final Study Guide with Complete Solutions How do plasmodesmata function in plant cell communication? Plasmodesmata are channels that connect plant cells, allowing the transfer of water, nutrients, and signaling molecules between them. What is the significance of operons in prokaryotic gene regulation? Operons allow prokaryotes to regulate the expression of genes by controlling the transcription of multiple genes simultaneously. How does the secondary str...

Honors Biology - Unit 2 Questions with Verified Solutions What is the term for the process by which cells take in large particles, such as food or pathogens, through engulfing? Phagocytosis What is the name of the fluid mosaic model that describes the arrangement and movement of proteins within the phospholipid bilayer of cell membranes? Fluid Mosaic Model What is the term for the cellular structure responsible for packaging and modifying proteins and lipids before they are se...

Honors Biology Basics Questions and Answers Already Passed What is the term for the chemical process where cells break down glucose to produce energy, without using oxygen? Anaerobic Respiration What is the name of the cell structure that contains enzymes to digest and recycle cellular waste? Lysosome What is the term for the process by which a cell membrane engulfs extracellular material to form a vesicle? Endocytosis What is the name of the pigment found in plant cells...

Honors Biology Unit 3 Test with Complete Solutions What is the primary role of the Golgi apparatus in the cell? The Golgi apparatus modifies, sorts, and packages proteins and lipids for transport to various destinations inside or outside the cell. How does passive transport differ from active transport? Passive transport moves substances across the cell membrane without energy input, while active transport requires energy to move substances against their concentration gradient. ...

Honors Biology Chapter 5 Latest Update Graded A+ What is the primary source of energy for most life forms on Earth? The primary source of energy for most life forms on Earth is the sun. How is energy stored in cells? Energy is stored in cells primarily in the form of adenosine triphosphate (ATP). What is the role of ATP in cellular processes? ATP provides energy for various cellular processes by releasing a phosphate group to form adenosine diphosphate (ADP). What is cellul...
