<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
None of the provided choices provide a completely correct answer. In fact, 75% of humidification takes place in the nose and mouth, with the rest taking place in the trachea. When you breath in, mucous
membranes inside the nose and mouth release
moisture to air. It is estimated that the average adult evaporates 200 to
300 ml of water per day during this process. The process is very efficient: while breathing in through
nose or mouth, the mucous membranes are cooled down. During breathing out, this cooling effect causes condensation of some of the moisture in the air coming from the
lungs, thereby moisturizing the mucous membranes
Answer:
Able to produce its own food
The answer is B. Is found only is a particular time period
Answer:
c) happened by chance
Explanation:
d and e answers are not correct:
mutations won't happen because of an environmental necessity, like being more efficient at eating grass, nor because a specific diet requirement, like eating seeds or grass. Mutations could happen if the organisms have the genetic pool to express a specific mutation dealing with a phenoypic character like longer teeth. If the organism doesn't have the genetic pool for developing longer teeth it will never have this feature, even if it keeps eating grass all its life.
A is not correct:
The mutation allowed the teeth to grow longer and to pass this feature to the next generation, but there is nothing that can predict an optimal length for eating grass to make them stop growing. Mutations are not a synonym of optimal features or benefit.
B is not correct:
It could happen that longer teeth arose in many members of the population, but we cannot say that it arose at the same time.
