Wes places red blood cells in a petri dish with pure water and observes them under a microscope. he drew a model to illustrate his observations. swollen red blood cells. one blood cell has burst, releasing its contents. what is the most likely explanation for wes’s observations? a. the red blood cells were placed into an isotonic solution. water moved into and out of the cells to maintain homeostasis. b. the red blood cells were placed into an isotonic solution. water moved into the cells until the cells burst. c. the red blood cells were placed in a hypertonic solution. water moved from the inside of the cells to the outside of the cells to maintain homeostasis. d. the red blood cells were placed in a hypotonic solution. water moved from the outside of the cells to the inside of the cells until the cells burst.

The correct answer is: D. The red blood cells were placed in a hypotonic solution. Water moved from the outside of the cells to the inside of the cells until the cells burst.

Hypotonic solution can be described as solution that has less solute and more water (H2O) than another solution. In order to maintain homeostasis, the water will move (via osmosis) into the cell, through the semipermeable membrane of the red blood cell.

D.The red blood cells were placed in a hypotonic solution. Water moved from the outside of the cells to the inside of the cells until the cells burst.

Explanation:

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
