Answer: Receptor potential
Explanation: Receptor potential can be defined as a graded response to stimulus. The distance traveled by the receptor potential is directly proportional the size of the stimulus. An example of a receptor potential is a tastebud. It can also be called a generator potential. A receptor potential always results into an action potential.
An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur.
At the very top of the swing the velocity=0. If the velocity is 0 then the kinetic energy is 0 as well because kinetic energy is the energy of movement.
Answer: Human activities is the most likely reason for it
Explanation:
A species is said to be extinct when there are no more individuals in that group, i.e, when a certain species of living beings definitively disappears from the planet. Since the emergence of the Earth, several species have disappeared and these extinctions happened for several reasons. Among the reasons, there are those caused by forces of nature such as earthquakes, volcanoes, changes in the planet's climate, such as glaciations - periods when certain parts of the planet were covered with ice, which caused the death of many beings that lived in those environments. However, in the modern society in which we live, the human being has been the biggest cause of the extinction of species.
The big problem is that the action of human beings has caused great environmental changes, altering the planet's climate, destroying habitats of several species. Human activities have a greater impact on terrestrial and freshwater ecosystems and for this reason the rate of extinction of terrestrial and freshwater species is higher than the rate of extinction of marine species
