Answer:
1→4→5→3→2
∙
Mitotic cell division starts with the condensing of chromosome accompanied by splitting of the centrosome and its movement towards the opposite poles.
∙
As the nuclear envelope and nucleolus disappear, spindle fibres arise from the centrosomes and start binding to the condensed chromosomes at the centromeres.
∙
The chromosomes bound by the spindle fibers are then arranged in the middle of the cell forming the equatorial metaphase plate.
∙
Next the centromere splits and the sister chromatids are pulled away towards the poles by the contraction of spindle fibres.
∙
Following this, a cleavage furrow starts to develop in the middle of the cell while the nuclear membrane starts to reappear around the separated chromatids.
∙
The condensed chromatids start thinning into chromatin fibre along with reappearance of the nucleolus and the cleavage furrow deepening further.
∙
Finally as the nuclear membrane becomes fully intact, the cleavage furrow deepens and split the cells from middle into two daughter cells.
It really depends on the type of genetic mutation. You see, genetic mutations can be both good and bad for us. For example, the ability to produce lactase is a desirable thing because it helps us digest and break down lactose, which is a type of sugar found in milk. If we did not have lactase in our bodies, when we consume milk, it would result in temporary sickness since we are unable to break it down. A bad genetic mutation could simply be being born without arms - obviously it is very uncomfortable, so it is undesirable.
Answer:
D: All levels contain the same amount of energy
Explanation:
This is due to how the number of animals also increase as the energy pyramid level decreases.
