involved! ^^ Fisherman at Reelfoot Lake, in Northwest Tennessee, noted a drop in the number of catfish. What is the most reasonable conclusion, based on the data provided? A)The pH of the rain will not affect the fish that live in the lake.
B)The pH of the rain falling into the lake is of level that it is killing the adult fish.
C)The pH of the rain falling into the lake is of level that it is affecting fish reproduction.
D)The pH of the rain falling into the lake is of level that it is both affecting fish reproduction and killing adult fish.

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.

a physical change is being made.
