In a species of tropical fish, e colorful orange end black variety called montezuma occurs. when two montezu- mas, are crossed, 2/3 of the progeny are montezuma, and 1/3 are the wild-type, dark grayish green color. montezuma is e single- gene trait, end montezuma fish are never true-breeding. a. explain the inheritance pattern seen here end show how your explanation accounts for the phenotypic ratios given. b. in this same species, the morphology of the dorsal fin is altered from normal to ruffled by homozygos- ity for a recessive allele designated f whet progeny would you expect to obtain, end in what proportions, from the cross of e montezuma fish homozy- gous for normal fins to a green, ruffled fish? c. whet phenotypic ratios of progeny would be expected from the crossing of two of the montezuma progeny from part b?

emerald ash borer

the emerald ash borer is a green buprestid or jewel beetle native to north-eastern asia that feeds on ash species. females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years. hope this !

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.
