Rerouting a river could affect fishing in the river downstream because
Natali5045456 [20]
Downstream river would have less water, so there would be less fish to catch.

River re-routing is a process wherein the mouth of the river is mouth to another location. Thus, existing mouth of the river will lose its water source and have less water. Fishes in the existing river path will decrease because of the decreased level of water.

Compare and contrast binary fission and conjugation. Which process increases genetic diversity?
Studentka2010 [4]
-Binary fission is the form of asexual reproduction and cell division used by prokaryotic organisms (such as bacteria or archea). A prokaryotic cell by divides into two parts, and each half has the potential to grow to the size of the original cell. 
<span>
-Bacterial conjugation is the transfer of genetic material between bacteria through direct cell-to-cell contact. It is merely the transfer of genetic information from a donor cell to a recipient. In order to perform conjugation, one of the bacteria, the donor, must play host to a conjugative or mobilizable genetic element, most often a conjugative or mobilizable plasmid or transposon. Most conjugative plasmids have systems ensuring that the recipient cell does not already contain a similar element.

Binary Fission- asexual
Conjugation- sexual

It's pretty confusing at the least really.

Tight rope walker does not want to change his position to make sure that   the force acting on him is balanced. A slight change in the position of the  rope walker will make the rope move and this movement will result in the unbalance the force exerted on the walker. So, to make the force balance he will not change his position.

Cellular respiration is a multipathway process that converts an organic substrate into cellular energy. The majority of energy i
umka21 [38]

Answer:

This is by co enzymes NADH and FADH2(adenine dinucleotide hydrogen and falvin adeninedinucleotide hydrogen. They are the co-enzymes that convey (electrons in )hydrogen atoms from the Kreb's cycle to the matrix of the  mitochondria.They are not enzymes,but rather, enhances the work of enzymes.

These co enzymes are oxidized by the loss of hydrogen atoms.The hydrogen spits into electrons and protons in the matrix.The protons is pumped into the intramembranes by the proton motive force produced from the  electron transport chains,and returned to the  matrix, to generate electrochemical gradient needed for  energy to be used by ATPase synthase for ATPs production

What is the correct order of sedimentary rock formation?
Talja [164]
Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.
