Option 1.  Involves incubation at 94°C to denature DNA strands into single strands by breaking of weak hydrogen links

<em>Annealing</em>

Option 3.  Temperature is lowered to 60°C to allow primers joining their similar DNA sequences.

SOMEONE PLZ HELP!!! How does immigration and emigration apply to human population growth?
Temka [501]
Immigration and emigration is typically done with the purpose of looking forward to a better and more prosperous life, a more comfortable life where the money you earn can last you a pretty long time and buy you enough thing to live more comfortable than where you used to live. Therefore, when you move to a prosperous country, having children is not something you’ll worry about given to the commodities you’ll have and the easy access to baby food and baby clothes and stuff, therefore, when people emigrate/immigrate to more prosperous countries, they’re comfortable with the idea of having more children, and that leading to population growth.

The caretaker of a farm feeds hay to the cows to procure milk from them. How much energy will the cows get from the hay?
nikitadnepr [17]

<u>Answer</u>: C) 10%.

<u>Explanation</u>:

  • The cow will get only 10% energy from the hay as the transfer of energy from a lower to a higher trophic level follows the ten percent law.
  • According to the ten percent law of energy transfer, only 10 percent of the total energy gets transferred to the next trophic level in a food chain.
  • For example, if the hay had 100 joules of energy, the cow will get only 10% of 100 J i.e 10 J energy.
  • The reason why only ten percent energy is transferred is because the rest is lost in the form of heat in the atmosphere.
