Answer:
Option). It permits hydrogen bonds between DNA strands to dissociate.
Explanation:
PCR (polymerase chain reaction) techniques can bed defined as a technique, which is used for in vitro amplification of sample DNA. It is made up of three steps, denaturation, primer annealing, and extension.
The first step in PCR is heating of sample DNA to denature the double stranded DNA by breaking hydrogen bonding present between bases of double stranded DNA.
Due to this, double strands of DNA get separated and provide templates for synthesis of daughter DNA strands.
Thus, the correct answer is second option.
Add a metabolic poison to the water to block any active metabolism and see if the seed germinates the same as without the poison.
- The percent increase in mass decreases with rising temperature. As temperature rises, its value approaches that of the percent increase in mass.
- There are two types of requirements for microbial growth: physical and chemical. Osmotic pressure, pH, and temperature are examples of physical factors.
- Water, supplies of carbon and nitrogen, minerals, oxygen, and organic growth stimulants are all chemical necessities.
- hence by using poison to block the active metabolism of seed the chemical growth will be restricted. If the seed still swells this means that it is a physical process.
- If the seed swelling stops then the process is considered chemical.

Answer:
An organism with high fitness has adaptations that are well suited to their environment allowing them survive and reproduce. An organism with low fitness has characteristics that are not well suited to their environment meaning they almost certainly die without reproducing.
Explanation:
Answer:
Delegates at the 1992 Fourth World Congress on National Parks and Protected Areas, a decennial international conference that serves as a global forum for setting the agenda for protected areas worldwide, recommended that “protected areas cover at least 10 percent of each biome by the year 2000.”
