There is variation within the population, due to a mutation. The selection pressure is the drug. The microbes that have the advantageous gene which makes them resistant to the drug are selected for, and reproduce passing on the gene, increasing its allele frequency within the population over time. However, the microbes that do not have the advantageous gene, cannot survive and their number decreases within the popullation.
<span>DNA exists in a coiled form in order for it to take up a smaller volume in the cell so that is why the first thing is that it needs to be unwound by topoisomerase. Then each piece is made up of two strands that must be separated as they need to be copied separately, so next the helicase unzips the DNA. DNA polymerase needs to have something to build off so because DNA can be synthesized, the Primase needs to make an RNA "primer". DNA is then synthesized but because it cannot synthesize the whole chromosome in one piece, after DNA synthesis, the ligase must glue the shorter pieces together to make the entire chromosome.
Correct Order
1. Topoisomerase unwinds the coiled DNA
2. Helicase unzips DNA to separate strands
3. Primase lays down short RNA strands
4. Polymerase synthesizes new DNA strands
5. The new strands are glued using ligase</span>
Potential and kinetic energy. Most object have kinetic energy. If an object is moving it is a kinectic energy. Potential energy is an energy stored in the position or arrangement of the object.
I would say that two products of the earth are coal and petroleum and when they are burned say in a car or a power generating facility they can be converted to fossil fuels.The burning of these fossil fuels are causing too much greenhouse gases and making the earth's temperature rise and resulting in more extreme weather so fossil fuels need to be phased out so the earth will remain inhabitable for humans.
Answer:
Insulin
Explanation:
Insulin signalling promotes lipid storage in adipocytes by both stimulating triacylglycerol synthesis and inhibiting its breakdown.
Insulin’s inhibition of lipolysis aids storage of lipids and also decreases circulating fatty acid level.
