A fish is excreting large volumes of water; we would describe it as ______________________ relative to its environment. : An osmoregulator that is hyperosmotic. Which of the following animals likely makes the most nitrogenous waste? A. Frugivorous Bat B. Insectivorous Frog C. Piscivorous Seal D. Granivorous Bird : C. Piscivorous Seal Which of the following statements about mammalian excretion if FALSE: A. Substances like solutes always diffuse across the nephron membrane, with directi...

(aerobic respiration) whay are two main types of energy releasing pathways : Both start at cytoplasm, one ends in cytoplasm, other ends in mitochondria What is a collection of light harvesting pigments called? : Photosystems In the Calvin-Benson cycle what bines with co2, and what does it make? : 1. Ribulose Bisphosphate 2. G3p Where does aerobic respiration occur? : Mitochondria During preparatory reaction pyruvate is oxidized into two-carbon ________ units and ___________________. ...

chapter 22 : natural selection The theory of evolution through natural selection is considered a scientific theory because __________. : All of the listed answers are correct.: - it is broad enough in scope to explain many observations -it is supported by a massive body of evidence from many disciplines -it is general enough to provide many testable hypotheses An adaptation is : a trait that gives an organism a reproductive advantage in the current environment 2 EXP: Evolutionary ad...

Evolution : Descent with modification-- Charles Darwin Change in heritable traits (genes) over time; change in allele frequency from generation to generation evolution is a scientific theory : a comprehensive explanation, supported with substantial evidence (like the fossil record). we are very confident that this is a real thing but not sure that it happens 100% of the time Before Darwin : Aristotle (philosopher): the scale of nature arranges species in a ladder order of lower to ...

Which of the following animals generally has the lowest volume of urine production? freshwater flatworm vampire bat marine bony fish salmon in fresh water : marine bony fish Birds, insects, and many reptiles excrete nitrogenous wastes in the form of uric acid, which _________ : reduces water loss compared to other nitrogenous wastes, but requires more metabolic energy to produce The movement of substances out of the glomerulus and into Bowman's capsule is referred to as _____. 2 ...

extracellular enzymes : increase protection against host defenses and attack and kill host defensive cells to enable spread of infection two extracellular enzymes : coagulase & hyaluronidase coagulase : -pathogen produces coagulase -coagulase causes formation of a clot around pathogen -kinase causes breakdown of a clot -bacteria is released into blood hyaluronidase : -pathogens approach epithelium 2 -pathogens produce hyaluronidase -pathogen can now invade deeper tissues Bacteria...

The theory of evolution by natural selection does NOT assume that: A) populations produce more offspring than can be supported in most environments. B) traits within a population vary. C) some traits that give individuals an advantage within their environment are heritable. D) individuals with advantageous traits will evolve to have higher fitness, making the trait more common over time. : D) individuals with advantageous traits will evolve to have higher fitness, making the trait more ...

the advantage of excreting nitrogenous wastes as urea rather than as ammonia is that ______. : urea is less toxic than ammonia Birds, insects, and many reptiles excrete nitrogenous waste in the form of uric acid, which ______. : reduces water loss compared to other nitrogenous wastes, but requires more metabolic energy to produce Ammonia is likely to be the primary nitrogenous waste in living conditions that include ______. : lots of fresh water flowing across the gills of a fish U...
