Answer:
C) 86 J of energy for every 100 J that enter it.
Explanation:
Efficiency is a measure of performance of an engine which can be calculated by the formula as given below to get in percentage:
Efficiency = energy output/energy input x 100
If the efficiency of a car’s engine is 14 percent it means that for every 100 joules of energy that is entered into it, only 14 joule is converted into useful output and rest of the 86 Joules is wasted.
The efficiency of any machine is never 100%, however, if any machine miraculously converts all the input energy to useful output energy, it means it is 100% efficient.
Hope it helps!
Answer: Look below =3
Explanation: That makes a total of 6 billion base pairs of DNA per cell. Because each base pair is around 0.34 nanometers long (a nanometer is one-billionth of a meter), each diploid cell therefore contains about 2 meters of DNA [(0.34 × 10-9) × (6 × 109)].
The cold-blooded animals need to bask in sunshine before they can move as quickly as warm-blooded animals on a cold day because it increases their rate of metabolism.
<h3>What are cold-blooded animals?</h3>
Cold-blooded animals are those animals that are not able to regulate and maintain their internal body temperature when there is change in the external environment.
Example of cold-blooded animals are snakes and turtles. They expose themselves to sunlight to help them with their body metabolism.
Therefore, the cold-blooded animals need to bask in sunshine before they can move as quickly as warm-blooded animals on a cold day because it increases their rate of metabolism.
