First and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus - ANS: Prophase Second phase of mitosis, during which the chromosomes line up across the center of the cell - ANS: Metaphase The third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles - ANS: Anaphase The final phase of cell division, between anaphase and interphase, in which the c...

positive-feedback mechanisms - ANS-- are you in a normal healthy individual - are used to amplify the effect or response of a system - sometimes can create a deviation from homeostasis that leads to death - cause the deviation from normal to become even more pronounced Which portion of a feedback mechanism carries out a response to change a body variable? - ANS-effector Homeostasis is the condition produced by - ANS-The tendency for change in a body variable to be counteracted as soon a...

Penn Foster Introduction to Biology Questions and Answers 100% Pass What is the role of the endoplasmic reticulum in synthesizing lipids and proteins? The smooth endoplasmic reticulum synthesizes lipids, while the rough endoplasmic reticulum helps in protein synthesis. How do prokaryotic cells reproduce? Through binary fission, where the cell divides into two identical cells. What is the purpose of the central vacuole in plant cells? To maintain cell rigidity and store nutrients...

What six functions characterize all living things? Organization Responsiveness Growth Reproduction Movement Metabolism/Excretion What is homeostasis? A steady state of internal environment of an organism. What is the difference between positive and negative feedback? Give an example of each. Positive feedback enhances change (labor contractions during birth, blood clotting, etc...) Negative feedback resists change (body temperature, insulin, cortisol, etc...) List...

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...

Chapter 01: Cellular Biology MULTIPLE CHOICE 1. A student is observing a cell under the microscope. It is observed to have supercoiled DNA with histones. Which of the following would also be observed by the student? a. A single circular chromosome b. A nucleus c. Free-floating nuclear material d. No organelles ANS: B The cell described is a eukaryotic cell, so it has histones and a supercoiled DNA within its nucleus; thus, the nucleus should be observed. A single circular chromosome ca...
