Well some aquatic organisms won't know what they are taking into their bodies and they could die from that thing...
Hello!
To solve this problem you need to use the following equation for heat transfer to calculate the heat added (Q) and substitute in this equation the values for specific heat (c), mass (m) and temperature difference (ΔT). The following equation describes the heat needed to raise the temperature of a given object:
:
So, to heat the cafeteria fork made of iron with a mass of 20 grams from 25 °C to 75°C, you'll need
121 cal of heat energy.
Answer:
Salivary glands make saliva, which aids in digestion, keeps your mouth moist and supports healthy teeth. You have three pairs of major salivary glands under and behind your jaw — parotid, sublingual and submandibular. Many other tiny salivary glands are in your lips, inside your cheeks, and throughout your mouth and throat.

Answer:
C. If microbes can live in toxic arsenic, they have evolved.
Explanation:
After reading the chapter "Earthbound Extraterrestrial? Or Just Another Microbe in the Mud?" We can conclude that if microbes can live in toxic arsenic, they have evolved. This is because toxic arsenic is not a favorable environment for any living thing. Living conditions in a toxic arsenic environment are very inhospitable for the development of microorganisms that are able to survive under these environmental conditions. However, some microorganisms can survive and reproduce more microorganisms with the same survivability. This process indicates that these microorganisms have evolved since this new generation has a feature that the past generation did not have.
Answer;
A. gases or particles present in high enough concentrations in the atmosphere to harm humans, other organisms and structures.
Explanation;
Air pollution is a type of pollution that occurs when harmful or excessive substances such as particulates, gases and biological molecules are introduced into Earth's atmosphere.
The burning of fossil fuels, such as coal, oil, natural gas, and gasoline to produce electricity and power our vehicles is the major cause of air pollution.
