Answer:
While digesting food, the liquid food then enters the small intestine where the acid is _neutralized_, and enzymes break down fat, protein and carbohydrates for absorption by tiny hairs called villi.
Explanation:
The small intestine is where most chemical digestion occurs. Most of the digestive enzymes that act in the small intestine are secreted by the pancreas and enter the small intestine through the pancreatic duct.
The enzymes enter the small intestine in response to the hormone cholecystokinin, which is produced in the small intestine in response to the presence of nutrients. The hormone secretin also causes <em>bicarbonate to be released into the small intestine from the pancreas in order to </em><em>neutralize</em><em> the potentially harmful acid that comes from the stomach.</em>
This is to protect the cells lining the small intestine from the acid.
<h2>Microbes and ruminants relation</h2>
Explanation:
The mixture of microbes allows the host animal to produce a much wider variety of digestive enzymes, far more than the host could encode in their own genome
- The microbes in the gut of ruminants include bacteria,fungi and protozoa
- These microbes helps the ruminant animals to digest food,without the microbes these animals would die
- The microbes break down feed to produce volatile fatty acids, which are used by the cow(ruminant animal) as energy for maintenance and milk production
The answer is; B
Mutation is one source of variation (in addition to sex and gene flow). Mutations are rare and occur in a small proportion of individuals. However, due to the advantage that the genetic mutation confers to these individuals, their chances of passing the genes to the next generation is higher than that of the general population.
This way, the allelic frequencies of these advantageous mutated genes increase with each generation and eventually become the majority population over time.
The drinking bird works by evaporation of ether inside its body and evaporation of water outside its head. The liquid ether in its body evaporates at room temperature. As it vaporizes it creates an increased pressure inside the body, which pushes liquid ether up the tube to the head.
The first law of thermodynamics, also known as law of Conservation of Energy, states that energy cannot be created or destroyed in an isolated system. The second law of thermodynamics states that the entropy of any isolated system always increases.
