The division of a bacterial cell into two daughter cells (called binary fission) is accomplished by a protein called FtsZ. FtsZ is very similar to the tubulin subunits that form microtubules in eukaryotes. After the replicated bacterial chromosomes have moved to opposite ends of the cell, a ring of FtsZ proteins forms inside the plasma membrane in the region where the cell will divide. As the FtsZ ring constricts, the plasma membrane and bacterial cell wall fold in and eventually separate into two cells. Division of a bacterial cell into two daughter cells. A chromosome, located mid-cell, replicates. Then two chromosomes pull apart, and a ring of FtsZ protein forms mid-cell. The ring contracts, the membrane and cell wall invaginate. Division is completed after the cells separate. Plant and animal cells also require cytoskeletal proteins for cytokinesis, although the roles these proteins play differ among bacteria, plants, and animals.

The question is incomplete and the complete question is:

For each space in the table, drags the appropriate label to indicate if the statement is true or false for each group of organisms

1. Cells divide by constriction of a ring of protein

2. The presence of a cell wall prevents the cell from diving by constriction

3. Tubulin or tubulin-molecules function in binary fission(in bacteria) or cytokinesis(in animals and plants)

1. Bacteria: true , Animals: true  and Plants: false

2 bacteria: false , Animals: false and Plants: true

3. Bacteria: true , Animals: false  and Plants: true

Explanation:

Option-1

Bacteria: true  as the protein FtsZ is involved in the binary fission and the formation of constriction.

Animals: true  as the microtubule ring is formed

Plants: false  as no constriction of the ring is formed instead of a cell divides by plate formation

Option-2

Bacteria: false  as the ring is formed and no cell wall is involved

Animals: false as there is no cell wall in the animals

Plants: true as the cell wall divides by plate formation

Option-3

Bacteria: true  as FtsZ is involved in the ring formation which is tubulin like structure

Animals: false  as the actin and myosin are involved in a ring formation

Plants: true as tubulin are involved

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 !
