BESC 204 TAMU EXAM 1 Question and answers correctly solved fungi - correct answer -own kingdom -3 domains (archea,eukarya,eucaryota) -eukaryotic -heterotrophic -no chlorophyll -obtain nutrients by absorption -reproduce by spores -exhibit a pronounced polarization of growing cells hyphae - correct answer each of the branching filaments that make up the mycelium -elongate by tip growth mycelium - correct answer vegetative part of a fungus, consisting of a network of fine wh...

Agonist - Competitive inhibition, binds to active site and causes a signal response in receptive tissue. Antagonist (blocker) - Competitive inhibitor, binds to active site so signal molecules cannot bind but causes no response in receptive tissue, can bind and release eventually. Apply your understanding of channels and synapses to predict how various neurotoxins affect nervous function. - Neurotoxins block receptor proteins on the post-synaptic neuron. Example: tetrodotoxin form Fugu fish...

OpenStax Microbiology Test Bank Chapter 3 The Cell * = Correct answer Multiple Choice 1. The idea that life could appear from nonliving materials was called which of the following? A. the cell theory B. the cellular genesis theory C. the theory of biogenesis D. the theory of spontaneous generation* 2. The first known use of epidemiology to trace the source of a disease outbreak was the identification of contaminated water as the cause of cholera transmission in London. Which of the ...

How do pseudohyphae in yeasts differ from vegetative hyphae in mold? Yeasts use pseudohyphae to invade host tissue, whereas mold use their vegetative hyphae for obtaining nutrients. Based on its Gram status, why are penicillin and other beta-lactam antibiotics effective against Streptococcus pneumoniae? Penicillin and Beta lactam antibiotics are effective against Streptococcus pneumoniae because it is a Gram positive organism and does not have a protein layer surrounding it's cell wall Choose...

Shoot system - consists of two portions: the vegetative (non-reproductive) parts of the plant, such as the leaves and the stems, and the reproductive parts of the plant, which include flowers and fruits. The shoot system generally grows above ground, where it absorbs the light needed for photosynthesis. Root system - which supports the plants and absorbs water and minerals, is usually underground. Meristematic tissue - either undifferentiated or incompletely differentiated, and they ...

Microbiology The study of microorganisms. The science which treats the nature, life and action of microorganisms. Me Him Contamination The state of being soiled or infected by contact with infectious organisms or other material Microns A unit of measurement; 1/1000 of a millimeter or 1/25,000 of an inch; usually designated by the Greek letter "u". Protoplasm Describes all living materials in a cell. A thick mucous-like substance that is colorless and translucen...

What do all fungi have in common? absorption of nutrients The hydrolytic digestion of _____ should produce the monomer, an aminated molecule of -glucose? Insect exoskeleton and fungal cell walls If all saprobic fungi in an environment were to suddenly die, which group of organisms should benefit as a whole? prokaryotes When a mycelium infiltrates an unexploited source of dead organic matter, what are most likely to appear within the food source soon thereafter? c. exoenzymes What is NOT ...

BIOL 2325L: FUNDAMENTALS OF MICROBIOLOGY LABORATORY| LAB REPORT 5| LATEST UPDATED 2024 SCORED A+ Differential Staining: Capsules, Endospores and Flagellates Introduction: Many staining procedures are available for use with microorganisms. Such stains target a specific part of the cell or may be used to identify a certain class or type of microorganism due to some unique staining feature. Several examples of such “structural” stains are the endospore stain, the capsule stain, and the ...

"-cide" - refers to killing. "Bacteriocide" kills bacteria, "fungicide" kills fungi, etc. "-static" - means 'to stand still'. Refers to an agent which prevents growth but doesn't kill. "Bacteriostatic" or "fungistatic" or "virustatic" agent "troph" means - eat A solution containing an antibiotic? - Filtration Abiogenesis - life arise from non-living matter Acidophiles - like low ph Active transport - Moving from lower to higher concentration. Aerotolerant - If there'...
