Answer:
A
Explanation:
The correct answer would be that <u>the availability of food resources for black mice and brown mice will decrease.</u>
<em>Since the food requirements of the black mice are the same as that of the invasive brown mice, the available food supply that used to be only for the black mice would now be shared by the two strains of mice. Hence, the available food for the two groups of mice will naturally decrease.</em>
There is no sufficient information to conclude that the population of tan mice will decrease, hence, option B is incorrect.
The black mice and tan mice have different food requirements going by the information available in the illustration, hence, both cannot compete for food resources. Option C is, therefore, incorrect. In the same vein, option D is incorrect because the tan mice have different food requirements from the brown mice.
<u>The only correct option is A.</u>
Answer:
This happens because viruses mutate and vary according to the environment they face. That is why different strains occur and appear every day, which must be updated in the vaccines, in order to have immunity up to date and keep up with the viral mutation without making us sick.
Explanation:
Viruses are acellular structures that do not have their own metabolism or replication method, it is because they must dominate and invade the human body so that its DNA or RNA is coupled to the human and this uses the human machinery to be able to replicate.
On the other hand, as infections occur and viruses appear, they can associate with bacteria forming bacteriophages, they can mutate within an organism that is infected by more than one viral infection and they can even adopt retrovirus mechanisms, which day by day. These new viruses are called as new strains, which evolve and will have to be coupled with vaccines.
Vaccines are a method of natural ACTIVE immunity, that is, part of the virus is inoculated, so that it generates the formation of a specific antibody in the body.
Answer:
Advantageous
Explanation:
Natural selection acts on traits that are advantageous, thus increasing chances of survival and passing on the trait.
Answer:
Low Enzyme Production is the reason for no breaking down of food.
Explanation:
If the digestion of food did not occur so it means that there is low enzyme production because enzymes are responsible for the breaking down of food substances into simpler ones in order to absorb by the cells for the generation of energy in the form of ATP. So we can conclude that low enzyme production is the only reason for the stopping of breaking down or digestion of food.
