Answer;
Natural selection
Explanation;
-Natural selection is one of the basic mechanisms of evolution, along with mutation, migration, and genetic drift.Genetic diversity allows the different organisms to have different physiological characteristics. Some of them provides them with genetic resistance, others don’t. The ones which are resistant survive the pesticide, others don’t ; this is known as natural selection.
-Those that are resistant will live longer and have a larger number of offspring (reproductive success). From one generation to another, there will be more and more resistant pests (because of their larger offspring), and less and less pests that are not resistant (because they tend to die young). If the selection process goes on, someday the pesticide will be useless (it will kill no pest).
<span>Eventually the smaller, lighter beetles will out breed the larger, darker ones. Because they can avoid predators more easily, allowing them to reproduce more often and with better results. The larger, darker beetles will inevitably be found more often by predators and as such won't be able to reproduce as often, or as safely, as the smaller, lighter beetles.</span>
Answer and explanation;
The level of organization in human body is;
cells → tissues → organs → organ systems → the organism.
-Cells are the smallest unit of any living thing. it is the basic unit of living organisms.
-Tissues are groups of specialized cells working together to perform a specific function.
-An organ is a complex system of tissues working together to perform a life task for a human body. Examples: Heart, lungs, liver, kidneys, eyes, brain, stomach, intestines, and pancreas are a few of the organs that reside in the human body.
-An organ system is a group of organs working together to keep the human body alive. They include; Digestive system, Respiratory system, Endocrine system, Immune system, etc.
According to experts, habituation occurs in the body. It is when there is a reduced physical response to a stimulus after one has been exposed to it repeatedly.
Sensory deprivation, on the other hand, occurs in the brain. This is when ones senses no longer have the same response to stimuli that is continuous or unchanging.
