Answer:
Herbivores and omnivores have evolved specialised muscles and dentition in order to sufficiently masticate their vegetation to allow for adequate digestion of the feed intake. Herbivores, when compared against carnivores, have a pronounced masseter muscle, which initiates and aids the movement of the jaw in a lateral movement, which grinds food on the flat molar dentition at the back of the mouth. An animal that can live solely on a vegetarian diet should have a pronounced masseter muscle to help break down the strong cellulose walls that would otherwise prevent the absorption of proteins and fat within the plant cell. Carnivores, however, have a masseter muscle that is smaller in size, due to the fact that the muscle cannot move the mandible in a lateral movement due to the shape of the jaw. It is noted in Dyce (1987), that the only movement of the mandible in a lateral movement will cause trauma, and is 'occasionally so severe that the coronoid process engages the zygomatic arch, locking the jaws in the depressed position'. This problem occurs due to that the mouth of evolved carnivores, such as the dog and cat having the scissor-like movement of the jaw bones, and the postglenoid process prevents the temporalis muscle from dislocating the jaw. This would evidently be possible because the temporalis muscle is a powerful muscle that joins the mandible to the top of the cranium by stretching from the large coronoid process in carnivores to the occipital region. The pronounced zygomatic arch on a carnivore's skull shows that it is bowed to allow the large muscle to work properly. It is believed that the temporalis muscle evolved to restrain prey species for consuming (Dyce, 1987; Pough, 2002). A strong temporalis muscle wouldn't have evolved as much as the cat, which is defined as an obligate carnivore.

Answer:
True
Explanation:
Physical contamination are foreign objects such as hair, fingernails, broken glasses , jewelries etc that are mixed with food. Although, it is important for a food handler who realizes that he is sick such as having fever, jaundice,wound while working to report such to his supervisor or manager,who will then take necessary action and to avoid risk of contamination; yet not the only cause of physical food contamination.
Physical contamination does not necessarily have to occur until the food handler is sick. It could be as a result of carelessness or not paying attention enough by the food handler . Physical contamination might not at all times cause injury or illness to the customer, yet such could bring discomfort to a customer who notices foreign objects in his food while eating. To avoid risk of physical food contamination, it is important for food handlers to keep jewelries to a minimum, wash fruits and vegetables thoroughly, wear hear neatly tied back, throw out and replace cracked, chipped, or broken dishware, glassware and equipment amongst others.
the type of asexual reproduction is Binary Fission
Answer:
sugars are not related to lipids
Answer: d. insulin
<span>Actually, there are two hormones secreted by islet cells within the pancreas: insulin and the glucagon. However, their secretions in response to blood sugar levels, are in opposite fashion! </span>
<span>Insulin is normally secreted by the beta cells of the pancreas while glucagon by the alpha cells. The </span><span>amount of insulin secreted into the blood increases as the blood glucose rises. In the same way, as the blood glucose falls, the amount of insulin secreted by the pancreas goes down.</span>
In glucagon, it is opposite. If blood glucose is high, then there is no glucagon secreted. Therefore, the answer is insulin.
