Pine rocklands are unique to southern Florida and the Bahamas. In Florida they are found on limestone substrates on the Miami Rock Ridge, in the Florida Keys, and in the Big Cypress Swamp. Pine rocklands are dominated by a single canopy tree, the South Florida slash pine. Fire is required for the maintenance of the pine rockland community. It influences v species composition, controls the invasion and growth of hardwood species, allows light to reach the understory and allows for pine regeneration. Fire intervals of prescribed burns range from 3 to 15 years in the pine rocklands. Review the image you see here. Based on your knowledge of succession, describe what is occurring here.

A) This is an example of primary succession caused by fire: we see the pioneer species, the annual plants, becoming established.
B) This is an example of secondary succession caused by fire: we see the pioneer species, the annual plants, becoming established.
C) This is an example of secondary succession caused by fire: soil is already present and several years have passed. We see annuals, grasses and perennial plants under the pines.
D) This is an example of secondary succession caused by fire: soil is already present and at least five years have passed. We see grasses, p

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c

explanation:

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.

some scientists like gregory adcock agree with thorne's theory of regional continuity.

others, like chris stringer and ian tattersall, believe thorne's results may be contaminated or misinterpreted.
