- Those who can not adopt to environment can not have their genes pass to next generation.
- Natural Selection is also called as "Survival of the fittest".
The temperature pattern which is being shown by the isotherms is that: D. temperatures increase from the center of the country toward the Southwest.
<h3>What is an isotherm?</h3>
An isotherm refers to a line that is drawn on a map to join points that are having the same temperature, in order to show the distribution of temperature in a geographical area on Earth's surface.
Based on the weather map in the image attached below, we can infer and logically deduce that temperatures typically increase from the center of the country toward the Southwest.

Answer:
The type of immunization used is passive, and the exact agent used is an antivenom. This type of immunization is necessary because the man does not have antibodies to fight against the venom's toxins.
Explanation:
To treat from snake bites is necessary to use antivenoms, these are given to the patient as soon as possible after the bite, they consist on a mixture of hyperimmune globulins and other proteins obtained from the serum of animals, usually horses or sheep, previously immunized with the venom of a snake. This kind of immunization is called passive immunization, is temporary and it uses exogenous preformed antibodies to provide treatment to an unprotected individual.
In this case, we use this kind of immunization because the person who was bitten didn't have the previous contact with the snake's venom, this means that the victim does not have antibodies to fight against the toxins in their body.
