Answer:
irritate people's breathing, ling cancer, asthma
Explanation:
Particulate matter in the air decreases life expectancy according to many researchers. Pollutants such as ozone irritate people's breathing, trigger asthma symptoms and cause lung and heart diseases. Exposure to environmental tobacco smoke causes many severe respiratory health problems such as asthma and lung cancer.
Natrual variations i think
Plants and fungi are usually filamentous to increase the surface area in which they uptake their food, and this is advantageous as they raise their surface area for sunlight in photosynthesis.
Conversely, animals are usually round to reduce surface area for loss of water and heat. Unlike plant and fungi, most of their food intake is through the mouth hence not affected by surface area.
The correct answer is A. They are synthesized.
In the endoplasmic reticulum, proteins are synthesized on to the surface of a rough endoplasmic reticulum. With the help of ribosomes which contains mRNA, the small bounded organelles enter the chamber where mRNA which contains proteins is being released.
Endoplasmic reticulum also regulates the quality of the proteins.
