What is rDNA technology?

Rdna is an abbreviation for recombinant DNA which means

DNA in which one or more segments or genes have been inserted, either naturally or by laboratory manipulation, from a different molecule or from another part of the same molecule, resulting in a new genetic combination.

Why deposits form in the steam vents of irons in some parts of the country?

Since steam is water evaporating, water that becomes steam may not be clean. So, when the steam goes thru, some of the dirt may come off along with the steam when the steam becomes water.Creating deposits in the steam vents.

Biological science from physical science?

Physics and chemistry is the base of all other sciences. Physics is the study of the properties of matter and energy and how they interact with each other, and chemistry is the study of how matter interacts with each other, how the combine, or how they change. So when it comes to biology it is a mixture of chemistry and physics. The way the human body is shaped is to work in an environment with gravity (physics). The way your body breaks down food into smaller sugars, fats, and proteins for later use (chemistry). Biology is the study of the chemical and physical properties of living creatures (and maybe nonliving (viruses). So to say that biological science is from physical science is somewhat true. I would say though that biology is more focused on chemistry than physics.

Biology is the study of life and living organisms, but physics is the study of motion.

They are indeed but to the definition of physics I would add ", mass and energy".

Physics also comes into biology in many ways, the simplest being the principles of sight and hearing. It's also the foundation science, for without the laws of physics nothing else could exist.

Is rain freshwater?

Most rain cannot be considered freshwater. It usually if full of acids and pollutants from our horrible economy.

What glowing gases observed during combustion?

Combustion is the general process of burning a material in the presence of Oxygen (O2). The glowing observed is the reaction itself that is taking place. A general example of a combustion reaction would be methane gas being combusted in excess oxygen.

CH4 + 2O2---> CO2 + 2H2O

What is a factor that is necessary for the formation of a new species?

One necessary factor for the formation of a new species is reproductive isolation, which prevents individuals from different populations from interbreeding and exchanging genetic material. This isolation can be caused by geographic barriers, behavioral differences, or genetic incompatibility, leading to the accumulation of genetic differences that ultimately result in the formation of distinct species.

What does moss grow from?

Moss typically grows from spores that are carried by the wind or water. These spores land on a suitable surface, such as soil, rocks, or trees, where they germinate and begin to grow into moss plants.

Why don't all hypothesis become theories?

A scientific theory is something that is tried and tested, and not yet disproven. It is close to being scientific 'fact' as you can get. Not all hypotheses will become theories because sometimes they get disproven. That means the hypothesis will need to be changed and tested again.

What does an oceanologist do?

An oceanologist studies marine life, ocean ecosystems, and ocean dynamics. They may conduct research, collect data, analyze samples, and monitor marine environments to better understand the oceans and their impact on climate, ecosystems, and biodiversity. Additionally, they may work on conservation efforts and advise on policies related to ocean management and sustainability.

Which two continents are not separated by a body of water western eastern northern or southern?

North America and South America are the two continents that are not separated by a body of water. They are connected by the Isthmus of Panama.

What is Land region of California?

The land region of California is diverse, with different ecological zones such as coastal areas, mountains, deserts, and valleys. The state is also known for its large swaths of protected land, including national parks like Yosemite and Joshua Tree. Overall, California's land region offers a wide range of landscapes and ecosystems.

What is the event of fertilization in human.?

Fertilization in humans occurs when a sperm cell penetrates and fertilizes an egg cell, resulting in the formation of a zygote. This typically takes place in the fallopian tube. The zygote then undergoes cell division and eventually implants itself in the uterus, leading to pregnancy.

Cans maybe made of a steel body and aluminum top why is that?

The steel body provides strength and durability to the can, while the aluminum top offers a lightweight and easily sealable material that helps to keep the contents fresh. This combination of materials allows for a balance of functionality and cost-effectiveness in can production.

Who was the first man to discover that the earth was a magnet?

William Gilbert, an English physician and natural philosopher, is credited with being the first person to explain that the Earth behaves like a giant magnet. In his book "De Magnete," published in 1600, Gilbert detailed his experiments and observations that led to this important discovery.

Does moss grow on a clean surface?

Moss grows anywhere it can. If an indoor surface is clean moss won't grow on it, but outdoors there's no such thing as a clean surface, so moss will grow there if the climatic conditions are right.

Find 80percent of 400?

first 400 is 4 times of 100 . so 80 percent of 400 is 4 times 80 which is 320. This can be done if the number is multipliable by 10.

When should you call an electrician?

Depends what your wanting to call one for, but when you notice an issue, try to find out the issue, id get it fixed as soon as possible, so the problem doesn't get worse. But if its something as simple as the Sink Disposal isn't working, then shut off the power to your home by locating the power box, and flipping the "Main" switch to "Off" then all power is off and you cant get harmed in anyways. Then you can start to look at your Disposal, If you see bad wires then cut off the wire that's bad, then go and get wire that will work and Splice the wires together, Google splice if you don't know what it is, its basically twisting the positive/negative wires to the other Positive/Negative wires and id also Recommend putting a Wire Nut on the Twisted wires, then make them facing opposite ways (One facing down, One facing up) // (Positive Up, Negative Down) Then i highly recommend putting electrical tape around the wire when your done, or atleast the part(s) that you spliced. Then flip the main switch to "On" and test your disposal or object that isn't working. So if you do it yourself you spend 10-15 dollars max, have a technician do it? your looking at 150-200 dollars. Its usefull to know simple things like these to save money.

Who is known for his pioneering researches in the field of chemistry and technology?

Dmitri Mendeleev is known for his pioneering research in the field of chemistry and technology. He is best known for creating the periodic table of elements, which laid the groundwork for modern chemistry.

What is dirt made of?

Dirt is made of a combination of minerals, organic matter, water, air, and living organisms like bacteria, fungi, and insects. The composition can vary depending on the location and the environmental conditions.

How can you protect biodiversity through science and technology?

  1. Use genetic engineering to preserve endangered species by cloning or gene editing.
  2. Employ GIS and remote sensing to monitor and map biodiversity hotspots for conservation efforts.
  3. Develop sustainable agricultural practices and biotechnology to reduce habitat destruction and promote coexistence with wildlife.

What are the differences between traditional biotech and modern biotech?

Traditional biotechnology is centered by passive techniques which lack efficiency and accuracy. Modern biotechnology uses gene manipulation to actively engineer organism with high efficiency and accuracy.

What is dirt made out of?

Dirt is made of a mixture of minerals, organic matter, air, water, and living organisms like bacteria, fungi, and insects. It varies in composition depending on factors such as location, climate, and the presence of plant life.

Is vaseline flammable when used with oxygen therapy in hospital?

Yes, Vaseline is flammable and should not be used with oxygen therapy in a hospital setting. Oxygen supports combustion, and applying Vaseline in oxygen-rich environments can increase the risk of fires. It is important to use oxygen-compatible products in these situations.
