which statement correctly explains the rise of liquid in the tube at the end of the experiment?
(1) the concentration of sucrose molecules increased as water molecules entered the bag. this concentration
increase pushed the liquid up the tube.
12) water entered the bag due to the lower concentration of water inside. the extra water pushed the liquid up
the tube as the bag filled.
(3) sucrose indicator entered the bag and reacted with the sucrose molecules. the reaction made the bag
increase in size and pushed the liquid up the tube.
(4) sucrose molecules moved out of the bag and up the tube while water moved out, causing the rise of liquid in
the tube.

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 !

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
