Which is the best characteristic that distinguishes the kingdom Archaebacteria from the kingdom Eubacteria

Answers

Archaebacteria are the oldest living organisms on earth. They are prokaryotes and unicellular. Archaebacteria are found in very harsh conditions (such as at the bottom of the sea or in volcanic vents). This is thought to be because the early Earth’s atmosphere was filled with poisonous gases and was very hot – nothing could survive, except the archaebacteria. These slowly gave way to modern organisms when the Earth’s conditions settled down and oxygen was introduced to the atmosphere. "

In relation to natural gas, where is crude oil generally found? A.
Crude oil is found above natural gas reservoirs.

B.
Crude oil is found next to natural gas reservoirs.

C.
Crude oil is found below natural gas reservoirs.

D.
Crude oil is mixed in with natural gas reservoirs.

Answers

crude oil does not float over natural gas in the pore space of a reservoir rock. upon drilling of these energy sources, crude oil is much deeper than the natural gas. This means the answer to this problem would be C.

Answer: The correct answer is-

C. Crude oil is found below natural gas reservoirs.

Crude oil is a unrefined form of petroleum. Natural gas and crude oil both are nonrenewable sources of energy that are formed by remains of plants and animals that died millions of years back.

Natural gas is lighter as compared to crude oil. So natural gas has lower density as compared to crude oil. Due to this, crude oil is found below the natural gas reservoirs.

Thus, option C) is the right answer.

Veterinary Science!! Scientists worry that even if they have successfully put together a vaccine for H5N1, this may not be enough to
eradicate the bird flu for good. Which fact would support this concern?

It would be difficult to convince poultry farmers to vaccinate their chickens because of the cost.

It would not be possible to vaccinate all poultry being grown for consumption against the virus.

Other forms of the virus have cropped up, such as H5N8 and H7N9, that would not respond to the vaccine.

Vaccinations against H5N1 are proven to be effective against other viruses such as H5N8, H7N9, and H1N1.

Answers

Other forms of the virus have cropped up, such as H5N8 and H7N9, that would not respond to the vaccine. The correct option is C.

Thus, the fact that additional strains of the virus, such H5N8 and H7N9, have emerged and do not react to vaccine supports the worry that, even if an H5N1 vaccine is effective, it could not be sufficient to completely eliminate the bird flu.

This is due to the fact that new virus strains can develop and emerge over time, and a vaccine that is effective against one strain might not be against another. Therefore, to tackle the bird flu and other emerging infectious illnesses, continual surveillance and the creation of fresh vaccines and therapies may be required.

Thus, the ideal selection is option C.

What percentage of alcohol is absorbed by the small intestine? 50-60%, 60-70%, 70-80%, 80-90%

Answers

Around 70-80% of alcohol is efficiently absorbed by the small intestine due to its big surface area. However, alcohol is also absorbed by all parts of the gastrointestinal tract. In fact, the stomach absorbs 10-20% of alcohol. This is the reason why people who have ingested food prior to drinking alcohol are able to hold their liquor better. Once the alcohol is absorbed, it travels throughout the body via the person's blood until equilibrium is achieved.

Final answer:

Approximately 90 percent of the water you ingest is absorbed by the small intestine.

Explanation:

The small intestine absorbs about 90 percent of the water you ingest. Water absorption is driven by the concentration gradient of the water, which is higher in chyme than in epithelial cells. Thus, water moves down its concentration gradient from the chyme into cells. The remaining water is then absorbed in the colon.
