Answer:
a. are often transmitted by fecal contaminated water and food.
Explanation:
<em>Eschericia coli</em> belongs to a group of bacteria generally referred to as fecal coliforms because they are of fecal origin.
<em>Hence, their common mode of transmission is through fecal to oral routes such as fecal contaminated food, water and any other substance that passes through the mouth.</em>
<em>E. coli </em>infections can be treated using suitable antibiotics.
The correct option is a.
Answer;
-Photosynthesis
Explanation;
-Photosynthesis is referred to as the process where plants use energy from the sun, carbon dioxide, and water to make food. Photosynthesis is largely responsible for maintaining and producing oxygen content of the atmosphere of the earth and then supplies all organic compounds and energy which is necessary for life.
- Carbon dioxide may be removed from the atmosphere when it is used by plants and algae for photosynthesis, dissolved in water, or deposited in the sediments on land or in the ocean. During photosynthesis there is photosynthetic conversion of carbon dioxide into carbohydrates by plants, releasing oxygen in the process.
The important point is that the surface area<span> to the </span>volume ratio<span> gets smaller as the </span>cell<span> gets larger. Thus, if the </span>cell<span>grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased </span>cellular volume<span>.</span>
Answer:
The mandibular canal, also referred to as the Inferior Alveolar Canal (IAC), sits within the mandible. It serves the purpose of housing the <em>inferior alveolar nerve</em> which is responsible for supplying sensation to the lower teeth.
This canal also houses the <em>inferior alveolar vein</em> - a dental vein whose function is to (with the assistance of the posterior alveolar artery) drain blood from the lower teeth and jaw.
A picture of the mandibular canal is attached.
