Phosphorus has an atomic number of 15. This tells us that... - Answer-there must be 15 protons True or False: covalent bonds are stronger than ionic and hydrogen bonds because atoms that are joined with covalent bonds share electrons - Answer-True An e- in a hydrogen atom exists in the first valence shell. The valence e- of Aluminum exist in the 3rd shell. Which valence shell e- have higher potential energy and why? - Answer-the valence e- of aluminum, bc higher e- shells have higher energy...

Test Bank for Essential Cell Biology 5th Edition Alberts Hopkin ESSENTIAL CELL BIOLOGY, 5th EDITION CHAPTER 1: CELLS: THE FUNDAMENTAL UNITS OF LIFE Unity and Diversity of Cells 1-1 Living systems are incredibly diverse in size, shape, environment, and behavior. It is estimated that there are between 10 million and 100 million different species. Despite this wide variety of organisms, it remains difficult to define what it means to say something is alive. Which of the following can be desc...

describe the basic functions all life forms must accomplish -response to environmental stimuli & maintain homeostasis -uptake and processing of nutrients/energy -regulation -growth and reproduction compare and contrast eukaryotic and prokaryotic cell types Prokaryotes: -circular chromosomes, no nucleus, no organelles, 3.5 bya -DNA concentrated in nucleoid Eukaryotes: -linear chromosomes, nucleus, organelles, 1.5 bya -DNA concentrated in nucleus Both: -cellular function takes p...

What are the properties of a eukaryotic cell - • Well define nucleus. • cells are larger and have more extensive intracellular anatomy and organization than do prokaryotes. • cells bind with deoxyribonucleic acid (DNA) and are involved in the super coiling of DNA. • cells have several chromosomes, protein production or synthesis . it consists of three components: outer membrane called plasma membrane, a fluid filling called cytoplasm, and the intra cellular organs or organelles ...

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...

Most of the cell membrane's specific functions are controlled by: - Proteins Alcoholic Fermentation is a form of: - Anaerobic Respiration Phagocytosis is a form of: - Endocytosis What is a pyruvate? - Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. One molecule of glucose breaks down into two molecules of pyruvate, which are then used to provide further energy, in one of two ways. What are the small spher...

CHAPTER 3 NEUROSCIENCE CHAPTER LEARNING OBJECTIVES 1. Understand the key methods that scientists use to learn about brain anatomy and functioning. • Neuroscientists examine autopsy tissue and patients with localized brain damage to learn about brain anatomy and brain function. • EEGs and neuroimaging, such as PET scans and fMRI, allow scientists to study brain function in the living brain. 2. Describe the two major types of cells in the nervous system and describe the prima...
