Why do some people not like cloning?
Answer
There are a both practical and moral opposition to cloning, but, for the most part arguments are theoretical since cloning is in its infancy right now. Cloning is one step beyond cross breeding, designer breeding, and genetic modification; all of which have their benefits and their pitfalls.
I personally think that a mutt is the best breed of dog, however there is a huge industry in pure breeding and designer breeding dogs. The benefits of designer breeding is that you get a dog breed that is expert in a task valuable to humans such as hunting, herding, or tracking. You can also get cute, adorable, or very intelligent dogs with personality traits that please humans a great deal; but you also get dogs prone to an endless variety of genetic disorders and diseases. And because humans have as many villainous traits as favorable traits, there are always the unscrupulous breeders that produce sick and damaged animals and sell some of those to the unsuspecting consumer only for the animal to suffer and die. This only briefly covers dog breeding, there are also a host of plant and animal breeders who are out there tinkering with nature.
There are too many pros and cons to cross breeding and genetic alteration to cover to make the point here. The example studies in the UK showing a 50% increase in allergic reactions to soy ingredients in just one year after the US increased imports of soy to the UK. Products sold to the public that are genetically altered or contain genetically ingredients are not labeled and the individual consumer of that product is at the mercy of producers. This includes manufactured food products as well as fresh foods. A vegetarian sitting down to a nice fresh salad runs the risk of suffering anaphylaxis due to a shellfish allergy. An extreme example but within the possibility of the current genetic alteration of our foods. A less dangerous but more widespread problem are changes like tomatoes and chicken whose taste bears little resemblance to the real thing and are very unappetizing to people who once liked tomatoes or chicken.
I realize that none of this is actually about cloning. That is because cloning doesn't have enough history, and the reasons that people don't like the idea of cloning is because there is no way to know what the negative consequences will be. The history of cross breeding and genetic alteration gives them a clue to what can and will go wrong and how unscrupulous people will misuse cloning for their own personal ends.
Answer
In 1994 I was taking a biology class in high school. We watched a video of cloning frogs. The process was quite simple. It involved taking an egg cell and any other cell from the frog. They would take the nucleus out of the cell of the egg and the nucleus out of the other cell. The other cell has all the DNA needed to form a healthy frog, so that nucleus would go into the egg cell. If the cell survived this process it would heal and start multiplying. About 1 out of every 100 cells would survive. This process has 2 names, cloning or twining. In essence it's creating a twin of the first.
The process used with the frogs is no different then what they used with sheep or even if they clone people. What is the same is ONLY the DNA. This creates a whole new individual. If it is a person cloned, they have to grow up just like anybody else, learn just like everybody else, and they would even have there own personality. So if a mass murderer or rapist or Obama would be cloned, they would end up nothing like the original. They would be just as different (if not more different because the age difference) as identical twins are. They would be able to make there own decisions and learn from older clones mistakes and achievements. It would not be much different then having a much younger sibling.
So then, why are people against it? Some people believe in the sacredness of life and think that human genes should not be tampered with. A question that can be raised is, when the process is complete, is a human created even if it dies? If one is against abortion, then they should be against cloning for the same reasons. It's creating a life that has no chance of survival. They could be creating hundreds of humans with no chance of living. So the main reason people are most likely to be against it should be for moral reasons. There are those that are against it for fear of creating "evil" people, but that is an ignorant reason for being against it. To be for it or against it, one should do their research, figure out exactly what it is and base their opinion on the facts of what it is and how it's done.
What is biotechnology a small definition?

What is the difference between Holiday model and double strand break model of recombination?
In 1964, Robin Holliday proposed a model that accounted for heteroduplex formation and gene conversion during recombination. Although it has been supplanted by the double-strand break model (at least for recombination in yeast and higher organisms), it is a useful place to start.
How is knowing the half-life of atoms useful?
Knowing the half-life of radioisotopes is useful for many reasons. We can look at a few examples to see why.
If we have radioactive material, we need to know the half-life to know how long it is dangerous. This applies to fission products inside spent nuclear fuel. This fuel generates heat long after it has been removed from a reactor, and we have to store this stuff securely for many human lifetimes. Fission products of uranium and plutonium are super nasty, and they must be kept out of harm's way.
Knowing the half-life of a certain material can allow us to date things that are old. Radiocarbon (carbon-14) is used to date things like skeletons or plant materials that archaeologists have recovered. We can also use something like uranium-lead to date rock structures back millions and even billions of years.
There is a broad range of radioisotopes that we find in use in the medical field, and we need to know the half-lives of them. We might select a short-lived radioisotope to act as a tracer for medical imaging. A medical staff member will inject a patient or will have him ingest this substance, and then medical professionals take pictures. Knowing the half-life allows us to prepare the material closely enough to the time of use so that it is "potent" enough for the application. In another use, a radioactive isotope will be implanted to irradiate a tumor in a patient. The half-life of the material must be known and coupled to the amount of the substance used to calculate dosage to a patient.
What jobs can get with a degree in bio technology?

When a cell engulfs large fragments of water it is called?
When a cell engulfs large fragments of water, it is called "pinocytosis." This process involves the cell taking up extracellular fluid and any solutes dissolved in it by invaginating its membrane to form small vesicles.
What is a meaning of intomology?
It seems there might be a typo in the term. Assuming you meant "entomology," it is the scientific study of insects. Entomologists study various aspects of insects including their biology, behavior, ecology, and diversity.
How has cloning influenced technology?
Cloning technology has played a role in advancing biotechnology and genetic engineering. It has contributed to medical research, agriculture, and conservation efforts by allowing scientists to replicate genes, cells, and organisms for study and experimentation. Cloning has also raised ethical and societal concerns regarding the use of this technology for human cloning and its implications on individual identity and genetic diversity.
What impact did Antisense technology have on cells?
Antisense technology can impact cells by interfering with the expression of specific genes, leading to reduced protein production and altered cellular functions. It can be used to selectively inhibit the expression of disease-causing genes, making it a potential tool for therapeutic interventions in various diseases. Additionally, antisense technology can help in understanding the role of specific genes in cellular processes.
What is horizontal displacement as per directional drilling?
Horizontal displacement in directional drilling refers to the distance between the starting and ending points of a horizontal wellbore. It measures how far the wellbore has deviated from its vertical axis to reach a target location. Increasing horizontal displacement allows for accessing more reservoir area from a single drilling location.
Why do people probably dislike leeches?
People likely dislike leeches because they attach to skin and suck blood, causing discomfort or pain. Additionally, they can transmit diseases and infections, which adds to the negative perception of them.

What makes hydrogen an ideal gas for car fuel?
Advantages of hydrogen (for fueling a car) :-
- Hydrogen is a green fuel : Hydrogen combusts or burns in presence of oxygen releasing large amounts of energy, and the resultant end product is pure water. Thus it is environmentally very safe
- Hydrogen is the lightest element in the periodic table : It is very light, thus storying large amounts of the gas, even in compressed form will not take much weight.
- Highly combustible : hydrogen reacts strongly in presence of oxygen
- Easier generation : Hydrogen can be produced by electrolysis of water, as it is a part of water (H2O) there are better techniques of obtaining H2 also.
- Low cost of generation : as it can be obtained from pure water, it is cheap
- Availability : As water is available universally.

Why might a high tech image provide more information about the brain than surgery does?
A high tech image, such as an MRI or CT scan, can provide detailed and non-invasive information about the structure and function of the brain in real time. This allows for better visualization of the brain's anatomy and activity, which can help in diagnosing and monitoring conditions. In contrast, surgery may be limited to visualization of surface structures and may not provide as comprehensive information about brain function.
Why are motion sensing lights sustainable?
Motion sensing lights are sustainable because they only activate when motion is detected, thus reducing energy consumption compared to lights that remain on constantly. This feature ensures that energy is not wasted on lighting areas that are not in use, leading to cost savings and a lower environmental impact.
