The salinity of a small inland lake has recently started to increase. researchers are planning to study the lake over several decades to investigate how freshwater organisms survive significant changes in their natural habitat. which of the following physiological mechanisms will the researchers most likely observe among the surviving organisms in the lake? a. prokaryotic organismus will use various menchanismus to counteract swelling of cells as a result of increased water uptake. b. single- celled organismuss will use various mechaismus to counteract the increased flow of water from cells to the entvironment. c. eukaryotic organismus will use various mencahismus to counteract the diffusion of positively charged ions across the cell membrane. d. eukarytic organismus will use mechanismus to counteract diffusion of swelling of scells charged ions of increased water uptake. e. multicellular organismus organismus will use various mechanismus to counteract the loss of cell adhesion as a result of calcium deficiencies.

White-tailed deer are considered to be an overpopulated species in the central united states. which of these events probably contributed the most to white-tailed deer exceeding their carrying capacity?

On a recent expedition to a remote region of northern canada, scientists uncovered skeletal remains from about 100,000 years ago. surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees fahrenheit (or 538 degrees celsius). which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures? (a) chemical changes that naturally occur during the process of decay in only one north canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found. (b) a little over 103,000 years ago, a large fire is known to have occurred in northern canada. (c) strong evidence exists that as early as 70,000 years ago, homo sapiens around the world relied heavily on fire to cook animals. (d) in the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.

Omg substrates with the same size and shape as the active site will bind to the enzyme. why is the key labeled the “bad” substrate?
