Answer: 1. Once an altered gene is placed on an organism it can not be reversed.
2. New organism created by genetic engineering could
present ecological problems.
Explanation:
Looking at the fact that genetic engineering employ the viral vector that carries the functional gene inside the human body system, the repercussion are still unknown. They may even replace an important gene in the human body which could be dangerous to human.
Answer:
Smaller populations have a greater chance of having one allele expressed disproportionately.
Explanation:
Genetic drift corresponds to a drastic casual alteration of the natural order, reaching the genotypic concentration of one or several species, not preliminarily involving natural selection factors, but caused by sudden events. Such phenomenon is characterized by the occurrence of ecological catastrophes, for example: earthquakes, tsunamis, tornadoes, floods, burnings, avalanches and other processes, affecting a large population contingent. Thus limiting the genetic content of a particular group, restricted to the prevailing individuals.
In this situation, with low variability, differentiated individuals will experience a more significant selection pressure in relation to the ascending lineage, which minimized the achievements of selection due to the high number of living individuals. In this scenario, smaller populations will have a greater chance of having a disproportionately expressed allele as the number of members is reduced. We can also see this effect if by using a coin we imagine that heads and tails are two alleles in a population and each coin toss represents one member of that population.
Take India for example.... people use the bathroom and bathe in rivers!
Now lets say we look at the US our pollution comes from factories, trash that people dont throw away, fertilizers and many more... but the difference is, that in developed countries like the US our water is filtered.... And in India water is not safe to drink
Answer:
transport of protons (H+) from low concentration in the mitochondrial matrix to high concentration in the mitochondrial intermembrane space
Explanation:
atpase pump can also be called atp synthase. this enzyme catalyses atp formation from adenosine diphosphate and phosphate. it has f1, stalk and f0 components. 3 positive hydrogen ions go through to make 1 adenosine triphosphate molecule. oxidative phosphorylation has to do with the loss of electrons. there would be electrons loss from NADH to FADH2. Cytochromes carries them through different series of transferases from I to IV and while on this positive hydrogen ions are released into mitochondrial matrix
positive hydrogen ions are moved back to lumen through adenosine triphosphate channels. a process called chemiosmosis. the pro
