The alveoli needs of the epithelium for the gaseous exchange and stratified squamous epithelium are formed of multiple layers the difficulty in a gaseous exchange
I think this is actually a physics question-
gravitational potential energy = mass*g*height. We know mass and g is constant, so all we need to know is the height of the basketball.
Hope this helps :)
Answer:
Option A. Oxpecker birds eat parasitic ticks off the backs of zebras, is the correct statement for Mutualism.
Explanation:
Oxpecker birds is a special type of bird which feed on the parasites that are present on the surface of zebra. These parasites causes harm to the zebra. Oxpecker birds free the zebra from the parasite while the zebra provides food to the oxpecker bird and both get benefit from each other. So it is Mutualism relationship.
Option D. A tapeworm latches itself in the intestines of a rat, feeding off all the nutrients eaten by the rat, is a type of parasitism relationship.
