d. Fe
(2) 12 atomic mass units
(3) the mass of one mole of carbon atoms
(4) the mass of 12 moles of carbon atoms
The mass of a proton is approximately equal to 1 atomic mass unit (AMU), which is much lighter than the weight of a mole of carbon atoms or 12 moles of carbon atoms.
The mass of a proton is approximately equal to 1 atomic mass unit (AMU). This measurement is a standardized unit of mass that physicists and chemists use to express the atomic and molecular weights of elements.
The proton, along with the neutron, makes up the nucleus of an atom, and both have approximately the same mass, which is about 1 AMU. This is substantially lighter than the weight of one mole of carbon atoms (approximately 12 grams), and even more so compared to the mass of 12 moles of carbon atoms.

Answer: Identical to its parent.
Explanation:
The cloning can be defined as the process by which genetically identical individuals of an organism is produced either artificially or naturally.
The cloning in case of biotechnology refers to the creating the clones of organisms or copies of cells or DNA of the parent cell that is being used in the process.
The parent cell is cloned and numerous copies is made just like that of the asexual reproduction in the nature.
Example: Dolly the sheep.
A cell created by cloning is genetically identical to its parent. The correct answer is option A.
DNA (deoxyribonucleic acid) is a molecule that carries genetic information and instructions for the development and function of all living organisms.
When a cell is cloned, it is essentially a copy of the original cell. This means that the genetic material in the cloned cell is identical to the genetic material in the original cell.
In conclusion, the correct answer is A) identical to its parent. A cell created by cloning is genetically identical to its parent.

Answer:
I think robots would be better. Even though it might take time or take a lot of money to make the robots, it is safer than sending humans into space. Also, if we were to send a ship somewhere far away in our solar system or even past it, it would be hard for humans, and they may not even survive long enough to get there. Robots, however, can survive longer, and, since they are programmed by humans, we can program them to record the data in space, and they can constantly record space as they travel. We also would be risking less lives, and wouldn't be putting too many risks on the survival of the humans sent into space. The only downside would be that the robots can malfunction, but other than that, robots are better. :)
Answer:
The National Aeronautics and Space Administration has a difficult task. It must convince U.S. taxpayers that space science is worth $16.25 billion a year. To achieve this goal, the agency conducts an extensive public-relations effort that is similar to the marketing campaigns of America's biggest corporations. NASA has learned a valuable lesson about marketing in the 21st century: to promote its programs, it must provide entertaining visuals and stories with compelling human characters. For this reason, NASA issues a steady stream of press releases and images from its human spaceflight program

The space agency is now saddled with the International Space Station, the budget-hemorrhaging “laboratory” orbiting Earth. NASA says the station provides a platform for space research and helps to determine how people can live and work safely in space. This knowledge could be used to plan a manned mission to Mars or the construction of a base on the moon. But these justifications for the station are largely myths. Here are the facts, plain as potatoes: The International Space Station is not a platform for cutting-edge science. Unmanned probes can explore Mars and other planets more cheaply and effectively than manned missions can. And a moon colony would be a silly destiny.
The Myth of Science
IN 1990 THE American Physical Society, an organization of 41,000 physicists, reviewed the experiments then planned for the International Space Station. Many of the studies involved examining materials and fluid mechanics in the station's microgravity environment. Other proposed experiments focused on growing protein crystals and cell cultures on the station. The physical society concluded, however, that these experiments would not provide enough useful scientific knowledge to justify building the station. Thirteen other scientific organizations, including the American Chemical Society and the American Crystallographic Association, drew the same conclusion.
Since then, the station has been redesigned and the list of planned experiments has changed, but the research community remains overwhelmingly opposed. To date, at least 20 scientific organizations from around the world have determined that the space station experiments in their respective fields are a waste of time and money. All these groups have recommended that space science should instead be done through robotic and telescopic missions.
These scientists have various reasons for their disapproval. For researchers in materials science, the station is simply too unstable a platform. Vibrations caused by the movements of astronauts and machinery jar sensitive experiments. The same vibrations make it difficult for astronomers to observe the heavens and for geologists and climatologists to study Earth's surface as well as they could with unmanned satellites. The cloud of gases vented from the station interferes with experiments in space nearby that require near-vacuum conditions. And last, the station orbits only 400 kilometers (250 miles) overhead, traveling through a region of space that has already been studied extensively.
Despite the scientific community's disapproval, NASA went ahead with experiments on the space station. The agency has been particularly enthusiastic about studying the growth of protein crystals in microgravity; NASA claims the studies may spur the development of better medicines. But the American Society for Cell Biology has bluntly called for the cancellation of the crystallography program. The society's review panel concluded that the proposed experiments were not likely to make any serious contributions to the knowledge of protein structure.
ADVERTISEMENT The Myth of Economic Benefit
HUMAN SPACELIGHT is extremely expensive. A single flight of the space shuttle costs about $450 million. The shuttle's cargo bay can carry up to 23,000 kilograms (51,000 pounds) of payload into orbit and can return 14,500 kilograms back to Earth. Suppose that NASA loaded up the shuttle's cargo bay with confetti before launching it into space. Even if every kilogram of confetti miraculously turned into a kilogram of gold during the trip, the mission would still lose $80 million.
The same miserable economics hold for the International Space Station. Over its history the station underwent five major redesigns and fell 11 years behind schedule. NASA has spent over three times the $8 billion that the original project was supposed to cost in its entirety.
NASA had hoped that space-based manufacturing on the station would offset some of this expense. In theory, the microgravity environment could allow the production of certain pharmaceuticals and semiconductors that would have advantages over similar products made on Earth. But the high price of sending anything to the station has dissuaded most companies from even exploring the idea.
