Answer: nucleolus
Explanation: Ribosomes are manufactured in the nucleolus. Ribosomes are the sites where protein synthesis takes place. Ribosomes are usually made up of two subunits: one large subunit and one small subunit. Ribosomes are manufactured and assembled in the nucleolus. Ribosomal proteins combines with four ribosomal RNA strands in the nucleolus to form two ribosomal subunits: one small subunit and one large subunit that make up the complete ribosome
Wild Bedbugs become insecticide resistant because of the mutations and natural selections.
<h3><u>Explanation</u>:</h3>
As the huge amount of pesticides and insecticides are sprayed in the rooms for cleaning, the pests and insects like bedbugs dies in huge portions because of the toxin. But some of the bedbugs remain alive as they have mutations that help them to detoxify the toxins given, or bypass the metabolic processes so that the toxins don't hamper them much.
Now as the population becomes very small(bottle neck effect), the nature selects these organisms over the other to propagate more sufficiently and enormously. As the nutrients and supplies are also available, so the bedbugs don't suffer any lack of nutrition which can be a determining factor of their population.
Thus the wild bedbugs become resistant to insecticides while the experimental one remain succeptible to insecticides.

Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.
The Doppler Effect is also known as red shift. Red shift shows the distance of galaxies. The redder the shift then the further away the galaxy, however the bluer the galaxy then the closer it is. Red Shift shows that the universe is continuously expanding. <span />
