Which of the following correctly describes contrasting features of a plant cell and an animal cell?
plant cells have a cell membrane, and animals have both cell walls and a cell membrane.
plant cells have lysosomes with enzymes, while animal cells have only the golgi apparatus.
plant cells have a large central vacuole that takes up most of the cell’s space, and animal cells have many smaller vacuoles.
plant cells have both rough and smooth endoplasmic reticulum, while animal cells have only smooth endoplasmic reticulum.

The correct answer is option Plant cells have a large central vacuole that takes up most of the cell’s space, and animal cells have many smaller vacuoles.

The coulees of the plant cells takes up a large volume of the plant cell structures, as they play a very important role in the maintenance of the turgor pressure in the plants. In the plant cell, generally have only one large vacuole. The animal cells have a large number of the vacuoles and the vacuoles are very smaller as compared to the vacuole of the plant cells.

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 !
