The researchers prepare an intron-free copy of the eukaryotic gene for the use in creating the transgenic bacteria by using the reverse transcriptase to make the cDNA from the mature mRNA
The structure of the eukaryotic genes. Most of the eukaryotic genes are contain the segments of the coding sequences (exons) that interrupted by the noncoding sequences (introns). Both the exons and the introns are transcribed to yield a long and primary RNA transcript.
Eukaryotic DNA is the linear, compacted into the chromosomes by the histones, and has the telomeres at each end to protect from the deterioration. The Prokaryotes contain the circular DNA in addition to the smaller, transferable DNA plasmids. Eukaryotic cells contain the mitochondrial DNA in the addition to the nuclear DNA

Answer:
This is true except they are called fault-block mountains
Explanation:
It will result in growth overshoot of bear and the population will exceeds the habitat's carrying capacity.
The fishes serves as food for bears in the food chain of the ecosystem (river). The abundance of fish means there is more and enough food for bears, which in turns enhance their growth and reproduction (exponential phase).
However, bears population will continue to increase (overpopulation) and the carrying capacity (i.e., the amount of resources an habitat can provide for its inhabitants) is depleted. Thus, competition, predation, disease outbreak and others, would set in, resulting to loss of species and habitat in the long run.

The reason animals need a continuous supply of oxygen is to<u> Obtain energy from their food.</u>
<u></u>
The most fundamental reason why animals need a non-stop delivery of oxygen is without it animals can't achieve sufficient power from their meals.
Cells require a steady delivery of power to generate and preserve the biological order that keeps them alive. This electricity is derived from the chemical bond energy in food molecules, which thereby function as fuel for cells.
The animal's metabolism converts oxygen into strength. All through this system, a waste gas called carbon dioxide is produced. To remove it, the carbon dioxide is carried lower back to the lungs, where its miles are collected and exhaled.
