You have reports from four different studies of the effects of a new pesticide on native populations of bees. Each report makes different claims about
whether the pesticide will harm bees and how harming bees can be avoided,
but the studies were done differently. Which of these studies would produce
the most trustworthy results?
O A. A preliminary study conducted for the company that makes the
pesticide.
O B. An investigation whose results have been replicated by several
independent research teams.
O C. A summary of the observations made by the farmers who field-
tested the new pesticide.
OD. A non-replicated experiment conducted by a company that
competes with the pesticide maker.

i do not know and i have a 100 in this class

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
