2. Commensalism: The Remora Fish feeds off the food scraps from the shark When one organism benefits, and the other isn't helped or harmed (,)
The remora has a suction cup on the top of its head to attach to the shark. It eats the
excess food that the shark doesn't eat and also gets a free ride (using no energy of its own
for movement). Does the remora cause any harm to the shark? Does the shark benefit
from the remora in any way?
3. Mutualism: The Plover cleans the teeth of the crocodile
When organisms do things that benefit each other (0,0)
How does the plover benefit?
How does the crocodile benefit?

The earth consists of a variety of different organisms. despite their diversity, however, some similarities on the structural and metabolic levels may be seen. these similarities can be attributed to a. similarities among organisms in their proteins and nucleic acids. b. the ability of organisms to readily adapt to sudden environmental changes. c. similarities in organisms' habitats and niches. d. the ability of all organisms to interbreed and produce new species.

What is the difference between how ionic and covalent bonds form

The kidney filters potentially toxic substances in the blood, and thus “clears” the blood of those substances. this clearance function is dependent upon and proportional to the diffusion gradient of the substance across filtering capillaries, i.e. if the concentration of the substance is doubled, twice as much will be cleared from each ml of blood that is filtered. suppose that the body produces a constant amount of a substance x per unit of time. the kidneys eliminate substance x at a rate directly proportional to the concentration of the substance and the volume of blood cleared each minute (c): elimination = c × [x], where [x] is the steady-state concentration of substance x. imagine an individual with an initial concentration of x equal to [x]0 who develops kidney disease. her baseline clearance c0 drops to one half of the original (½c0). what is the new steady state concentration of x? (for simplicity, assume that substance x is 100% filtered by the kidney).
