Since some organisms are able to switch metabolic pathways depending on if oxygen is available they have an adaptive advantage. For other organisms if there is no oxygen then there is no respiration.
i thought i knew but im not going to lie.I hate spiders
the advantage is that all the nutrients and food is already broken down so there for it makes it easier on the worm to consume.
the lungs can better exchange oxygen and waste products in the blood.
The closure of the ductus arteriosus at birth in a fetal pig helps shift blood flow from the pulmonary artery to the lungs, as the lungs become functional after birth. This redirection of blood improves oxygenation of the blood, supporting the piglet's transition from receiving oxygen from the placenta to breathing air.
Peripheral vision allows you to see more than what is right in front of you. Therefor, if a predator is trying to sneak up on you, then you will be more likely to notice it if you have peripheral vision, because the animal certainly won't come up right in front of you. So the adaptive advantage is primarily in avoiding danger, such as a predatory animal.
as the trees are lungs of the earth we should not chop trees and just plant them.
The function of the exoskeleton is to protect the internal organs and support the crayfish because it is an invertebrate.
The dolphin has some important adaptations. A dolphin has live births so it doesn't have to stay with eggs, it has lungs but can also swim for a while underwater.
Adaptive Radiation :)
an extensive surface area well suited for invasive growth and absorptive nutrition.
Its white fur actually allows light to reach this skin and the dark skin absorbs the heat from the sun
