Homeostasis is the state of maintaining steady internal conditions by the living organisms. Cells obtain energy through the process of cellular respiration. It is a metabolic process of conversion of the biochemical energy from the nutrients into adenosine triphosphate (ATP). It also maintains the temperature of the body. The energy produced during this process is used in the cell division and repair of the cells by the breakdown of ATP and maintains homeostasis. They exchange substances with the new cells and also eliminate the wastes thereby maintaining homeostasis.
This phenomenon can be explained by Allen's rule. It says that the body proportions and shape may vary in different climates. The temperature decreases as the latitude increases, so in the northern region is much colder. Animals must preserve heat in such conditions. So, exposed surface areas of the body, such as the ears, feet, and tail, are usually minimized to minimize heat loss in the cold climate. <span>Therefore, northern species often have smaller ears, feet, and tail than the southern species. </span>
Answer:
Genus
Explanation:
In the scientific name "Panthera tigris", Panthera is the name of the genus and the "tigris" is the name of the species. Similarly in the name "Panthera leo", the name "Panthera" denotes the genus while "leo" is the species. This means that the tiger and lion belong to the same genus. They both belong to the genus "Panthera".
Though the species of the tiger is "tigris" and that of the lion is "leo". Both are the species of the same genus since the genus includes closely related species. The members of these different species can not interbreed but share some common features as they belong to the same genus.
