<h3>The discovery that is related to careers in biology is</h3><h3 /><h3>B. The discovery of the genes that are responsible for Alzheimer’s disease</h3>

Explanation:

Biology is the study of Life and living organisms. Any person associated with research or scientific studies of living organism is directly related to careers in biology.

Alzheimer's disease is a genetic defect caused in living beings. The genes causing this disease are:

  • Amyloid precursor protein (APP)
  • Presenilin 1 (PSEN1)
  • Presenilin 2 (PSEN2)

Due to mutation of these genes the nerve cells get damaged and patients begin to show the symptoms usually at the age of 60 and above. The genetic test results can help in early prevention and cure to Alzheimer's disease. Though research is being continued to find if there are more genes involved.

rjkz [21]

Answer:

The correct answer would be A) ribosomes.

A ribosome is a vesicular structure present in both prokaryotic and eukaryotic cells. They consist of ribosomal RNA and associated proteins.

They are the site of translation in both prokaryotic and eukaryotic cells.

They are made up two units which are called large sub-unit and small sub-unit.

In prokaryotic cells, 70S ribosomes are present which are made up of 50S large sub-units and 30S small sub-units.

In eukaryotic cells, 80S ribosomes are present which are made up of 60S large sub-units and 40S small sun-units.
