Your Question;
<span>What are 3 abiotic factors where emperor penguins live?
My Answer;
First, we need to know what "abiotic" means. Abiotic non-living, now that we know what "abiotic" means we can determine three abiotic factors.
One: Snow
Two: Wind and Water ( These are two different ones but I wanted to put it as one)
Three: Soil/Dirt.
Hope I helped,

The isopropanol will extract the DNA from the strawberries.
Explanation:
Strawberries help in DNA extraction as it has enzymes and pulverizes easily which breaks the cell wall and has large number of DNA in it. The isopropanol helps in precipitating the DNA.
In an experiment of DNA isolation, a squashed and refrigerated strawberry was added in a isopropanol solution after filtering it. It can be seen DNAs are starting to isolate from the strawberry extract in the form of fluffy bubbles.
Answer:
<u>Active transport across membranes is like refilling an empty soda can after pouring the soda into a cup. It takes effort (energy in the form of ATP) to pour the soda back into the can, it wouldn't typically happen on its own.</u>
Explanation:
Cells use several transport mechanisms to move substances across their plasma membranes. Plasma membranes control all movement of substances through passive transport, which does not use energy; and active transport which requires chemical energy in the form of ATP.
Active transport moves substances out of cells against their gradients. In the cell, glucose can be transported inwards for respiration. However, because the internal environment is typically concentrated, (and glucose is needed in high amounts) this requires the use of transport enzymes and ATP.
Heat because if u move enough energy of any kind it creates heat like the friction from rubbing ur hands together
