Understanding Physiological Adaptation
Before discussing the adaptation of physiology, it would be nice to know what is meant by adaptation. Adaptation is a system of how the organism in overcoming the environmental stresses around it to survive.Which organisms that can adapt well will be able to survive and who cannot adapt well will accept the consequences of not becoming extinct or becoming rare kind.
One type of adaptation is a physiological adaptation. In the sense of physiological adaptation is the way living creatures to adjusting themselves to the environment through work function in the organs of the body that aims in order to survive. This type of physiological adaptation is rather difficult if observed because it occurs only on the inside of the organs of living things.
Precisely, the adaptation of physiology is an adaptation that includes the functioning of the body. This adaptation can be in the form of an enzyme obtained from an organism. But physiological adaptation may be reversible or may return to its original state. Examples of Physiological Adaptation
In adaptable living beings there are several examples that can be seen in the explanation below, namely:
Examples of Human Physiology Adaptation
The example of physiological adaptation in humans is as follows:
The number of red blood cells that live on the coast are fewer than those living in mountainous areas. This is because of the partial pressure of oxygen in the coastal area more than the mountainous area. When the oxygen partial pressure is low, too much red blood cells are required to bind oxygen.
The average athlete has a larger heart size than the heart size of people in general. When it's hot, we'll sweat. Come out dry, make our body will be cold because body heat is taken to evaporate the drying on the surface of our bodies.
In cold weather, people are more likely to urinate more often.
The human eye can adjust to the intensity of light it receives. When in a dark place, the pupils will open wide. Conversely, if the place is bright, pupils will narrow eyes. The narrowing or narrowing of the pupils is an attempt to regulate the intensity of light.
Examples of Behavioral Adaptations in Plants
In plants, there are several examples of physiological adaptations that can be seen, including:1. Banana trees have leaves that are wide and thin and coated with wax to be able to adapt to the environment.
2. Ferns adapt to the humid environment by rolling the young leaves.
3. In order to survive in tidal waters, the mangrove tree has a hanging root which works for breathing
4. There are several types of plants that can produce a kind of acidic substances to prey on insects or animals.
5. Water hyacinth and water spinach have hollow stem making can live and grow in water.
6. Dikotil plants have beautiful flower crowns and have a function to attract insects to help pollinate
7. Flowering plants will often produce nectar to attract insects to help pollinate
8. A hazel shrub in the country of Japan, acacia trees can release substances that are toxic to herbivorous animals.
Examples of Physiological Adaptation in Animals
While in animals, there are several examples of physiological adaptations, among others are:1. When in a place or area of cold air, cold-blooded animals the speed of metabolism will decrease.
2. While animals that warm-blooded metabolism speed will rise when in a place or area with hot temperature.
3. Camel keeps the water reserve of the hump sac so the camel can survive in dry areas or deserts.
4. Owls have sharp eyesight at night, making it easy to find prey.
5. Fish that live in the ocean will release a more concentrated urine than with fish that live in fresh water.
6. Animal species of a weasel can emit the odor from their bodies, this function as a protector of the enemy's threat.
7. Squirrel-like animals exist that can extract the water that comes from the grain so that the animal can survive in dry areas.
8. The chameleon possesses Mimicry's ability, enabling it to change its skin color according to its environment or residence and avoid predators or from its enemies.
This has been explained about the Understanding of Physiological Adaptation, Examples of Physiological Adaptation in Humans, Animals, Completed Plants may be able to increase your insight and knowledge.
