The parental generation makes the F1 generation not the F2
The part of the CNS that is responsible for these functions is the brain stem.
The brain stem is the part of the brain that control very basic functions of your organism and lets them work together as they should. The other parts that are mentioned all have much more specific and also different roles.
Answer:
Natural selection
Explanation:
Natural selection is a process where some organisms are able to reproduce more and survive better due to the presence of beneficial genetic traits in them. The other organisms of the same population that lack these traits are not able to survive and reproduce in the same way. The bacterial having drug resistance are able to survive in the presence of drugs in the surroundings. These bacteria will reproduce more and leave more progeny. Over the generations, the proportion of the bacteria with drug resistance will increase. This represents an example of natural selection.
A way in which models cannot be useful is: B). being a perfect representation of a situation.
<h3>What is a model?</h3>
A model can be defined as the creation of a physical object either from kits, components or other applicable materials that are acquired by the builder, so as to simulate a phenomenon or process.
This ultimately implies that, a model should be probabilistic in nature rather than being perfect, so as to effectively illustrate or describe the relationship that is existing between an independent variable and the dependent variable.
Generally, some of the ways in which models cannot be useful include the following:
- Building intuition for situations.
- Making predictions that can be verified.
In conclusion, we can infer and logically deduce that way in which models cannot be useful is being a perfect representation of a situation.

90 mammal species become extinct in the period 1901-2000 than became extinct in the period 1801-1900.
Extinction is a situation in which something no longer exists. Their can be many reasons associated like species have been hunted to the point of extinction, scarcity of food or natural disasters.
Their are two main types of extinction firstly Mass extinction that has occurred only five times in history. The other is Background extinctions which occurs over longer period of time and are considered important in natural extinction rate.
