Milk generation presently causes much more contamination than it utilized to, mostly because so much of the production is solidified into huge dairy ranches, and transfer of that kind of fluid squander is troublesome without harming adjacent water sources.
The answer is 7 / good luck :)
<u>Answer:</u>
- few nutrients
- high pressure
- low temperatures
<u>Explanation:</u>
1. Few nutrients: open-ocean zone is located way far from the land, which is the main source of the essential nutrients.
2. High pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.
3. Ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface.
4. Varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.
5. Low temperatures: the temperature of open-ocean zone ranges from a low of -2°C to an average of 17°C.
Answer:
D. Titan's atmosphere contains nitrogen.
Explanation:
- Titan is the largest satellite of Saturn.
- It is the second largest moon next to Ganymede.
- Titan's landscape is similar to earth's and show dry rivers and hydrocarbon lakes. it is the only body in the solar system that shows evidence of surface liquid other than earth.
- It is the only planetary moon in the solar system which has an atmosphere which is rich in nitrogen like earth.
Because of their ability to undergo FREQUENT MUTATIONS, VIRUSES CAN RAPIDLY EVOLVE.
Viruses are one of the microscopic organisms that causes diseases in plants, animals and humans. Diseases cause by virus are usually difficult to treat because of the capacity of viruses to undergo frequent mutations; that is, they change their genetic components in a very rapidly manner, in such a way that, their genetic components are never the same for long. This makes it difficult for scientists to make effective drugs against viruses. Two different viruses can also combine together to form a new and unique type of virus. This is the major reason why diseases such as HIV, do not have a cure yet.
