Answer:

If the oil spilled in the gulf would have been processed oil, it would be worse than a normal oil spill as these oils have a higher shelf life.

Explanation:

Oil spills happen when a large quantity of oil gets mixed with large water bodies like sea and oceans. The oil being denser than water floats on the surface and does not mix with the water. It forms a coating on top of the water.

The difference between processed oil and normal oil is that they are heated at very high temperatures and this results in oxidation which creates free radicals, which are not good for the body and its cells. Also they have a very long shelf life due to which they will remain on water for a long time.

When oil spills happen, the wind cause the spill to spread over the water surface, thereby engulfing a large amount of area. The major disadvantages of the spill are:-

The oil gets stuck in the feathers of the birds who come by to dip themselves,
Animals like whale, dolphins have blow holes for releasing water. the oil covers these holes and makes it difficult for them to breathe.
The fur of animals like seal and otter gets mixed with the oil and can prove harmful to them as it gets them exposed to cold.
The overall BOD of the water body decreases, and organisms which use sun rays coming inside the ocean suffer as these get blocked.
Since processed oil has longer shelf life, a large quantity of animals will suffer and die.

The invention of the electron microscope opened up many doors for biologist’

The invention of the electron microscope opened up many doors for biologists as it helped them to view and learn the appearance of cells and their sub-cellular structures

<h3>What is an electron microscope?</h3>

Electron microscope are microscopes which helps biologists to view the appearances of cells of organisms which cannot be seen with our nak -ed eyes.

Generally, electron microscopes:

Uses a beam of accelerated electrons as its source of illumination
Helps in obtaining high resolution images of biological and non-biological specimens.
It is also used in biomedical research

In conclusion, electron microscope helps biologists to view, learn and to also understand the appearance of cells and their sub-cellular structures

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.
