ADVANTAGES AND DISADVANATAGES oF genectic enginerring

Answers

Advantages of genetic engineering would be that we would be able to eliminate natural and unnatural born diseases and genetic malfunctions within the human body. for example, with genetic engineering we would be able to eliminate the single causing factor for a person having cancer or a brain tumor. A disadvantage would be tampering with nature and how we as human beings are made/composed of

Advantages of Genetic Engineering?

1. It allows for a faster growth rate.

2. It can create an extended life.

3. Specific traits can be developed.

Plants and animals can have specific traits developed through genetic engineering that can make them more attractive to use or consumption. Different colors can be created to produce a wider range of produce. Animals can be modified to produce more milk, grow more muscle tissue, or produce different coats so that a wider range of fabrics can be created.

4. New products can be created.

5. Greater yields can be produced.

Genetic engineering can also change the traits of plants or animals so that they produce greater yields per plant. More fruits can be produced per tree, which creates a greater food supply and more profits for a farmer. It also creates the potential for using modified organisms in multiple ways because there is a greater yield available. Modified corn, for example, can be used for specific purposes, such as animal feed, ethanol, or larger cobs for human consumption.

6. Risks to the local water supply are reduced.

Because farmers and growers do not need to apply as many pesticides or herbicides to their croplands due to genetic engineering, fewer applications to the soil need to occur. This protects the local watershed and reduces the risk of an adverse event occurring without risking the yield and profitability that is needed.

7. It is a scientific practice that has been in place for millennia.

Humans in the past may not have been able to directly modify the DNA of a plant or animal in a laboratory, but they still practiced genetic engineering through selective breeding and cross-species or cross-breeding. People would identify specific traits, seek out other plants or animals that had similar traits, and then breed them together to create a specific result. Genetic engineering just speeds up this process and can predict an outcome with greater regularity.

What Are the Disadvantages of Genetic Engineering?

1. The nutritional value of foods can be less.

When animals grow, and mature quickly, the nutritional value of that product can be reduced. This can be seen in poultry products today with the white striping that is found in meat products. That striping is a fat deposit that was created, often in the breast meat, because of the rapid growth of the bird. In chickens, Good Housekeeping reports that this can increase the fat content of the meat consumed by over 220%. At the same time, the amount of protein that is received is also reduced.

2. Pathogens adapt to the new genetic profiles.

Genetic engineering can create a natural resistance against certain pathogens for plants and animals, but the natural evolutionary process is geared toward creating pathways. Bacteria and viruses evolve a resistance to the resistance that is created by the genetic engineering efforts. This causes the pathogens to become stronger and more resistant than they normally would be, potentially creating future health concerns that are unforeseen.

3. There can be negative side effects that are unexpected.

Genetic engineering is guaranteed to make a change. Many of those changes are positive, creating more and healthier foods. Some of those changes, however, can be negative and unexpected. Making a plant become more tolerant to drought might also make that plant become less tolerant to direct sunlight. Animals may be modified to produce more milk, but have a shortened lifespan at the same time so farmers suffer a greater livestock.

4. The amount of diversity developed can be less favorable.

At some point, genetically engineered plants and animals make it “into the wild” and interact with domestic species. This results in a crossing of “natural” and “artificial” organisms. The engineered organisms often dominate, resulting in only a modified species over several generations, reducing the diversity that is available.

5. Copyrighted genetic engineering can have costly consequences.

Many companies copyright their genetic engineering processes or products to maintain their profitability. If a farmer plants genetically modified crops and the pollination process causes another farmer in the field over to have those modified crops grow, there have been precedents for legal actions against the “unauthorized” farmer. This can have several costly consequences, from fewer farmers wanting to work to a higher cost for the seeds that are planted.

6. This knowledge and technology can be easily abused.

At the moment, genetic engineering in humans is being used to treat specific disorders that threaten the health or wellbeing of individuals. In time, the approach in humans could be like what is already being done with plants and animals. Genetic engineering can change specific traits, which could create human outcomes that are ethically questionable or easily abused.

why is polystyrene soluble in acetone and not water

Answers

Polystyrene and acetone are not soluble in water because they are non-polar substances.

A polar substance is a substance that has opposite charges on two ends of the molecule. In polar molecules, a dipole moment exists in the molecule and accounts for its interaction with water.

Water is a polar solvent. It can only dissolve polar molecules. Since polystyrene and acetone are both non-polar substances, polystyrene dissolves in acetone and not in water.

This agrees with the principle in chemistry that like dissolves like.

since we cannot measure to absolute zero, how can we determine what the volume will be at that temperature?

Answers

Answer:

We can measure volumes approaching absolute zero and then predict what the volume would be at absolute zero.

Since there is NO molecular motion at absolute zero, the volume of a balloon at absolute zero should be zero.

If you headed to the deepest recesses of intergalactic space, shielded from starlight, the only thing that would heat you up would be the Big Bang's leftover glow: the cosmic microwave background at 2olume.ht v725 K.   At that temperature, the balloon would have a volume.

          Charles' Law asserts that a gas's volume (V) and temperature (T), which must be expressed in Kelvin, are directly proportional to one another. A change in temperature of one Kelvin unit corresponds to a change in one Celsius degree. Never forget that the value 0 on the Kelvin scale corresponds to -273 or "Absolute Zero."

What will the volume be at absolute zero, and how can we calculate it?

          Charles's Law, V = a T+ b, is used to calculate absolute zero once the mass measurements are transformed to high and low temperature gas volumes.

         The volume of an ideal gas would theoretically be 0 at absolute zero, and there would be no more molecular motion. Actually, above this temperature, all gases condense into solids or liquids.

           According to Boyle's Law, gas volume grows as pressure lowers. Charles' Law states that when the temperature rises, the volume of the gas increases.

          Gases compress infinitely as the temperature is lowered because there is a linear relationship between temperature and pressure for the majority of gases (see gas laws). The volume of an ideal gas would theoretically be 0 at absolute zero, and there would be no more molecular motion.

B. Pb2+ (aq) + Sn (s) → Sn2+ (aq) + Pb (s)
C. Mg2+ (aq) + Ag (s) → Ag+ (aq) + Mg (s)

Answers

A spontaneous reaction is one in which the change in free energy is negative and the standard cell potential is positive.

For a redox reaction to be spontaneous, the electrode potential of the cell must be positive and this depends on the relative electrode potentials of the species involved in the reaction. A metal can not displace a metal above it in the electrochemical series from solution.

Based on this;

Fe2+ (aq) + Al (s) → Al3+(aq) + Fe (s) is spontaneous because iron is lower than aluminium in the electrochemical seriesPb2+ (aq) + Sn (s) → Sn2+ (aq) + Pb (s) is spontaneous because lead is lower than tin in the seriesMg2+ (aq) + Ag (s) → Ag+ (aq) + Mg (s) is not spontaneous because magnesium is above silver in the series.

Answers

Answer:

When the temperature of a system goes up, the pressure also goes up, and vice versa. The relationship between pressure and temperature of a gas is stated by the Gay-Lussac's law.

Answer:

We find that temperature and pressure are linearly related, and if the temperature is on the kelvin scale, then P and T are directly proportional (again, when volume and moles of gas are held constant); if the temperature on the kelvin scale increases by a certain factor, the gas pressure increases by the same factor.
