The answer is D. Mutualism is the symbiotic relationship when both organisms benefit. Predation is not a symbiotic relationship. Parasitism is the symbiotic relationship where one organism benefits and the other is harmed.
Answer: The body maintains homeostasis by positive and negative feedback mechanism.
Explanation:
The body maintains the internal temperature and metabolism with respect to change in environment.
In case the temperature outside is very cold and the body starts shivering by the movement of skeletal muscles, this is done to maintain the temperature inside body. This is positive feedback.
When the temperature inside the body is maintained, then body stops shivering. This is negative feedback.
This is how the body maintains homeostasis.
The answer to this is the Immune System.
The Immune system is made up of a network of cells and tissues and organs that work together to protect the body. The white blood cells (also known as Leukocytes) is part of the immune system, they help destroy disease causing organisms or substances.
That is why when you fall ill and like a few days later you are all better, that is because of the immune system.
Sometimes when somebody has a weak immune system they fall ill more easily and could die because the bacteria that makes you sick isn't being destroyed by the immune system. Sometimes the person has to go to the hospital for treatment and some medications that can help support their immune system.
Hope this helped :)
Have a great day
Answer:
It is most likely formed underground
Explanation:
Answer:
The correct answer is - Option B.
Explanation:
Before the Industrial Revolution, the light color moths were predominant so that they can blend in with the light-colored trees and lichens in their environment. After releasing coal smoke from factories, the trees became darkened, and the light-colored moths become an easy target for predator birds to spot.
Over time, the frequency of the dark moth increased due to they had a higher survival rate in habitats affected by the air pollution and it blends with darker coloration blended with the sooty trees. This is a shift in the population’s genetic variance toward the new, phenotype.
In graph B, light color moth frequency decreases, and after natural selection increases over time and after a decrease in evolution the dark color again decreases.
