Answer and Explanation:

Easter Island, a small island of around 64 square miles, has been a mystery for many scientists who study the changes on the past and current biodiversity abundance. According to research, this island used to be extremely diverse in species of fauna and flora, especially the latter. However, it is now composed of few species of invertebrates and little to almost no vegetation. This occured due to the first colonizers who rapidly deforested the region.

Research suggests that, apart from this deforestation, which caused the decline of wildlife species that depended on shrubs and palm trees, Polynesian colonisers introduced the Polynesian rat, which consumed almost all of the trees that were present in the island, leading to the absence of their regeneration.

Which statement most likely describes the daughter cells produced in the diagram

Juliette [100K]

Answer:

The daughter cells will each produce offspring that will have the same genetic information as the original cell.

Explanation:

The diagram you were given is shown in the image attached below. The options you were given are the following:

The daughter cells will pass on only half of the genetic information they received from the original cell.
The daughter cells will each produce offspring that will have the same genetic information as the original cell.
The daughter cells will each undergo the same mutations as the original cell after reproduction has occurred.
The daughter cells will not pass on any of the genes that they received from the original cell.

The diagram shows what cell division looks like. Cell division is the process in which we get two daughter cells from one parent cell. When a cell divides, everything in it divides as well. This is how daughter cells end up with the same structure (e.g. same organelles) as their parent cell.

The daughter cells have the same genetic information as their parent cell. This means that the cells produced by these daughter cells will have the same genetic information as the original parent cell.
