The primary cause of foodborne illness in north america is due to ingested bacteria.
The major pathogenic bacterial species are: Salmonella, E.coli, Campylobacter, and Staphylococci
Answer:
During translation the cell uses information from messenger RNA to produce proteins.
Answer:
The lids of the Petri dishes were inadvertently left on while being sterilized
Explanation:
- The process of eliminating any microbe from a particular object to achieve a sterile aseptic environment is termed as sterilization.
- Sterilization mainly aims to either remove, kill or make any microbe inactive by using various means such as irradiation, heat, pressure, etc.
- In the given question radiation is used to sterilize the Petri dishes and thus, if sterilization is successful there should not be any contamination.
- However, since there is contamination present amongst the bacterial colonies growing on agar plated in the Petri dishes this shows that the sterilization has not been done successfully and a possible reason for this could be that while sterilizing the<em> lids of the Petri dishes were kept on. </em>
The ocean is a carbon sink, with carbon being utilized by photosynthesis of phytoplankton describes the availability of carbon in the ocean and its use by marine processes
The ocean is a carbon sink, with carbon being utilized by photosynthesis of phytoplankton.
<u>Explanation:</u>
The carbon is found in the ocean is utilized by the phytoplankton found in the ocean. The carbon sinks in the ocean and then the process of photosynthesis required the carbon dioxide and the sunlight.
The ocean plays an important role in the carbon cycle, the carbon spreads in the ocean are called the ocean sink because it takes up more carbon from the atmosphere. The chemical and biological processes influence the carbon by producing more carbon dioxide in the atmosphere.
Answer: High Specific Heat Of Water
Explanation:
Water’s high specific heat helps to maintain low temperature and protects fish life. This is due to the presence of hydrogen bonds in larger amount between water molecules. Of course, specific heat plays a role to capture more energy without rise in temperature.
When heat gets absorbed, water molecules move freely and hydrogen bond gets broken. If temperature decreases, release energy by forming hydrogen bond. Hence, it clearly shows that this water property can drastically change the temperature quickly which is important in protecting a fish in a shallow pond on a hot summer day.
