Substrate Concentration on Enzyme Activity Correct Answer-• Increasing the concentration of substrate increases the rate of reaction (True up to a saturation point). • Collisions are more likely so more E-S complexes form. • The concentration will decrease over time therefore the rate of reaction will also decrease. • Therefore, the initial rate is the highest. As Km increases, affinity ____________ Correct Answer-decreases Homeostasis Correct Answer-A tendency to maintain a bal...

Amensalism -/0 interactions - : one species is harmed while the other is unaffected Tend to be more accidental than other relationships Example: a herd of elephants that crushes plants and insects while moving through a forest . Commensalism +/0 interaction: - one species benefits while the other is unaffected Brown-headed cowbirds follow grazing cattle and bison, foraging on insects flushed from the vegetation. Cattle convert plants into dung, which dung beetles can use. Dung beetles dispe...

Regulators - ANSWER-keep a physiological parameter constant despite fluctuations in the environment Regulators (graph) - ANSWER- Conformers - ANSWER-allow a physiological parameter to fluctuate with the environment Conformers (graph) - ANSWER- Homeostasis - ANSWER-Maintaining a stable condition (regulators) - regulation of internal environment - external environment can be highly variable - within a range rather than fixed 2 methods homeostasis can be regulated - ANSWER-1. Intr...

DAT Organic Chemistry Review Practice Test. Which are more stable conformers - CORRECT ANSWER staggered What are the rate laws of SN2 and E2 reactions - CORRECT ANSWER rate= k [RX][Nu:-] rate depends on concentrations of alkyl halide and nucleophile What are the rate laws of SN1 and E1 reactions - CORRECT ANSWER rate= k[RX] rate only depends on the concentration of the alkyl halide E2 elimination reactions must occur in bonds that are - CORRECT ANSWER coplanar or antiperiplan...

MCAT Organic Chemistry Written Exam. Electrostatic Forces - CORRECT ANSWER The attractive force between electrons and the nuclei that is responsible for all molecular bonds. Coordinate Covalent Bond - CORRECT ANSWER One nucleus donates both of the electrons in the bond. Hybridization - CORRECT ANSWER sp - 180° - linear sp2 - 120° - trigonal planar sp3 - 109.5° - tetrahedral, pyramidal, or bent dsp3 - 90°, 120° - trigonal-bipyramidal, seesaw, t-shaped, linear d2sp3 - 9...

Bio 316 Quiz 1; Questions and Answers 100% Correct Which of the following statements is FALSE for conformers? Conformers have a physiological mechanism conforming their bodies to their environment. A change in an animal's physiology in response to an abiotic stressor would be an example of... Phenotypic plasticity In our Alpaca example from lecture 1, the individuals with the highest hematocrit and reproductive output demonstrated all the following except... Adaption over the course ...

d) Cells can divide up the labor of performing essential physiological processes. correct answers Which of the following is a main benefit of multicellularity? a) Each cell can perform all of the necessary physiological processes needed by the body. b) Each cell can dump its waste directly into the environment c) Only some body cells need to make ATP. d) Cells can divide up the labor of performing essential physiological processes. e) Each cell has direct access to nutrients in the enviro...

Anatomy Biological form Physiology Biological function Interstitial fluid Fluid in the space between cells, which links exchange surfaces to body cells Regulators Uses some internal mechanism to control internal change regardless of external fluctuations (Warm blood) Conformers Allows internal environment to vary with certain external changes (Cold blood. temperature depends on the environment)

Endosymbiosis a mutually beneficial relationship in which one organism lives within another advantages of multicellularity 1. Organization of many cells into a single mass reduces SA to V ratio 2. Permits subdivision of labor amongst different tissues (specialization) origins of multicellularity 1. Intercellular connections (loss of cell wall in animal cells creates vulnerability) 2. cellular specialization 3. Communication (division of labor of cells means they must work together) 4. Evolutio...
