Answer: 90% energy is your answer
During cellular respiration, the bonds of food molecules are broken to energy can be released to fuel other cellular processes. In order for this to occur, new compounds with lower-energy bonds must be formed when high-energy bonds in food molecules are broken.
This is due to the Law of Conservation of Energy.
The journey of the food through the digestive system will actually digest the food. The rest will be given out as feces.
<h3><u>Explanation:</u></h3>
The digestive system actually consists of digestive tract and Digestive glands. The processes that are associated with digestive system is - ingestion, digestion, absorption, assimilation and egestion.
The food that is taken is first smashed and chewed into a rough bolus by mixing with saliva. The salivary amylase slightly digests the starch into dextrin.
Then the food is engulfed through the oesophagus into stomach. Inside stomach, the food is mixed with an enzyme pepsin and HCl. Pepsin digests the proteins into peptones and peptides. The food is converted into a bolus and transported into duodenum.
In duodenum, there are several enzymes from small intestine and pancreas breaks the fats into fatty acids, proteins into peptides and starch into carbohydrates like glucose. They are absorbed and the undigested substances are left over ad feces.
That would be false. Chicken pox is caused by varicella zoster virus and hepatitis is caused by hepatitis B virus (i.e. the common form of hepatitis)
Answer:
b. Common structures with different functions suggest that the species share a common ancestor that also had a similar structure.
Explanation:
The presence of organs with the same basic structures in the organisms of different species reflects their homology. It represents the fact these species shared a common ancestor that also had a similar structure. These homologous organs with identical basic structural plans have been used by the members of different species to perform different functions. For example, the bones of the forearms of humans and flippers of whales are the same. Humans use forearms mainly in holding objects while flippers assist whales in swimming.
