Natural selection is one of the leading theories in the Theory of Evolution, because it’s supported by evidence from a variety of scientific disciplines, including paleontology, geology, genetics and developmental biology.
Answer:
Urban heat
Explanation:
Urban heat is a terminology generally used to describe the higher temperature with in the cities as compared to the surrounding woods.
Jessica moved to industrial area which has large industries that continuously release heat and pollution in the environment. Due to this the environment in and around the industrial area is much warmer as compared to the outskirts of the cities (with mountains).
Also the cities have offices & residential apartments, traffic and automobiles that continuously release heat and pollution thereby further enhancing the temperature of cities.
Hormones are a group of chemicals released by exocrine glands
These hormones are directly secreted into bloodstream from where they reach the site.
Answer:
The answer is: Classical Conditioning.
Explanation:
- According to the theory of Classical Conditioning, an Unconditional Stimulus can be defined as such a stimulus that is capable of triggering a response spontaneously and naturally without the requirement of a previous learning or knowledge about the stimulus.
- A Neutral stimulus can be defined as such a stimulus which is responsible for drawing or focusing the attention of a person to a particular event.
- A Conditional Stimulus can be defined as such a stimulus which is generated due to the repeated integration of an Unconditional stimulus to a Neutral stimulus. The repeated integration eventually results in the generation of a conditioned response.
- In the given example, a bit of black pepper blown into the eyes for the first time is an example of unconditional stimulus. This stimulus initiates a spontaneous or unconditional response, that is, blinking of eyes.
- But, when this unconditional stimulus gets integrated to the neutral stimulus (irritation in the eyes draws the attention of the person) repeatedly, it can result in the generation of a Conditioned Response (blinking of eyes whenever any foreign object gets into it).
Necessary because it keeps heat in and keeps the planet at the right temperature for life.
It can harm the planet if more pollution occurs and the greenhouse gas effect traps too much heat and causes global warming
