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.

Answer:

The maximum number of electrons present in a particular shell is calculated by the formula 2n2, where “n” represents the shell number. For instance, K shell is the first shell and it can hold up to 2(1)2 = 2 electrons. Similarly, L shell is the second shell and it can hold up to 2(2).

Answer:

9.13 x 10^-8 m

Explanation:

The maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.

Wavelength is defined as the distance between identical points in the adjacent cycle of a waveform signal propagated in space or along the wires.

Wavelength is calculated as wave speed and frequency.

Wavelength = speed/frequency

SI unit of wavelength is meter.

A ground state atom is an atom in which total energy of the electron can not be lowered by transferring one or more electrons to different orbitals.

Thus, the maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.

numer 1:Neutrons are required for the stability of nuclei, with the exception of the single-proton hydrogen nucleus. Neutrons are produced copiously in nuclear fission and fusion. They are a primary contributor to the nucleosynthesis of chemical elements within stars through fission, fusion, and neutron capture processes.

Explanation:

The most likely ion of Aluminum is Al³⁺ (group 3A) since losing three electrons is the most energetically favorable way for it to follow the octet rule.

Because the charge on ions is equivalent to their oxidation state, then +3 is the most likely oxidation number of Aluminum.

Explanation:

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here calcium is having an oxidation state of +2 called as Ca^{2+}Ca2+ cation and NO_3^{-}NO3− is a polyatomic anion with oxidation state of -1.. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral Ca(NO_3)_2Ca(NO3)2
