Water is the single source as it provides the electrons by splitting into oxygen and hydrogen. This process happens during the light-dependent reactions.
Answer:
The Ring of Fire contains approximately 850–1,000 volcanoes that have been active during the last 11,700 years (about two-thirds of the world's total). The four largest volcanic eruptions on Earth in the last 11,700 years occurred at volcanoes in the Ring of Fire.
Explanation:
Answer:
For the 1st part, the correct answer is option C.
In a polymerase chain reaction, the amplification of DNA template takes place not RNA. So, prior to going into the process, there is a need to initially convert RNA into DNA with the help of an enzyme reverse transcriptase.
For the 2nd part, the correct answer is option D.
The suitable temperature for human DNA polymerase is 37 degrees Celsius, and it gets denatured at greater temperatures. As PCR runs at exceedingly high temperature like 95 degrees Celsius, only Taq DNA polymerase can withstand the temperature. Thus, normal DNA polymerase cannot be utilized in the PCR reactions.
Answer:
The water cycle is a process in which water is lost from water bodies and then it again comes back to earth in form of rain. This is how I know it, but the explanation is correct.
Explanation:
See,
- Water from water bodies evaporates and becomes water vapour due to heat
- This then reaches high altitudes, where it condenses with dirt to create small droplets thingy
- This then creates a cloud, which on correct saturation with water, makes it rains.
This cycle goes on continuously creating a cycle which is termed the water cycle.
