BIOL 172L EXAM 1 UH MANOA; Questions and Answers 100% Solved Endosymbiosis Correct answer Organelles originated when a single-celled organism engulfed another single-celled organism • Usually obligate: the survival of one depends on the other the process in which unicellular organisms engulf other cells, which will then function as organelles within the host cell. Studies of DNA sequencing suggest that green and red algae developed when heterotrophic eukaryotes engulfed cyanobacter...

AP Biology Exam Question and Answers Verified 100% A+ 2024, With Rationale. The resting membrane potential depends on which of the following? I. Active transport II. Selective permeability III. Differential distribution of ions across the axonal membrane A. III only B. I and II only C. II and III only D. I, II, and III D The resting potential depends on active transport (the Na+K+-ATPase pump) and the selective permeability of the axon membrane to K+ than to Na+, which leads t...

They are also referred to as consumers. Primary consumers may be herbivores herbivores - ANSWER-plant eaters omnivores - ANSWER-plant and meat eaters Secondary consumers - ANSWER-are carnivores, meat eaters, or omnivor...

Bacteria shapes - Cocci, bacilli, vibrios (comma shaped), spirilla (spiral), pleiomorphic (various shapes) adherence molecules to stick to surfaces - - mediated by pili, fibers of pilin proteins possess other proteins on their tips for sticking - a sex pilus is used for conjugation - some microbes use an extension of the cell envelope tipped by a "holdfast" of paysaccharides 3 parts of flagella - - filament - hook protein - basal body active transport - - all microorganisms active tr...

Macronutrients - carbon, nitrogen, phosphorus, sulfur, oxygen, hydrogen, potassium, sodium, magnesium, calcium, and iron Micronutrients - manganese, zinc, cobalt, molybdenum, nickel, copper All organisms require - Carbon, Hydrogen, Oxygen, and electrons Autotrophs - Assimilate carbon from inorganic sources Heterotrophs - Assimilate carbon in preexisting organic form Phototrophs - Capture light energy to produce ATP Chemotrophs - Capture energy from oxidation of reduced organic ...

BIO 441A EXAM 3 STUDY GUIDE WITH COMPLETE SOLUTION. LECTURE ONE - METABOLISM INTRODUCTION ● Autotrophs synthesize all their own cellular constituents from simple molecules ● Heterotrophs obtain energy through oxidation of organic compounds and therefore rely on autotrophs ● Metabolism involves many reactions such as ○ Glycolysis/gluconeogenesis ○ The citric acid cycle ○ Oxidative phosphorylation ● Catabolism is the degradation of biomolecules ○ Energy rich nutrients are...

Life emerged on Earth shortly after the planet was formed, some BLANK years ago. - 3.8 billion Microbes are tiny living things that are found all around us and are too small to be seen by the naked eye. They live in water, soil, and in the air. The human body is home to millions of these microbes too, also called microorganisms - True Extremophiles are microbes that survive in intense conditions, such as very high or low temperatures. - True What is the difference between autotrophs and he...
