When DNA was discovered, Watson and Crick saw that the strands of the double helix are lined up in the opposite direction of each other. This type of orientation is called the antiparallel orientation.
The antiparallel orientation is a type of orientation showing two polymers present side by side but running in the opposite direction. The best example of this is the deoxyribo nucleic acid (DNA). DNA molecule is made up of a pair of polynucleotide strands which are antiparallel. The antiparallel orientation of the DNA facilitates the hydrogen bonding between the two complimentary strands. This is also important for the processes of DNA replication and transcription.
Because they occurred one after another, they happened repeatedly.
A. "power plant" that provides energy for cells
The food we eat is brought to the mitochondria and broken down. Once it gets broken down the mitochondria converts the food into ATP
Hope this helped!

Absence of oxygen means anaerobic respiration ; which has 2 different pathways.
First Pathway ; Alcoholic fermentation which takes place in yeast.
Pyruvate is decarboxylated into ethanal releasing co2 as waste product.
Ethanal is toxic , so its reduced by help of NADH to ethanol in presence of alcohol dehydrogenase enzyme , and Free NAD is released to continue glycolysis.
2) The second pathway is Lactic fermentation which takes place in mammalian muscles.
Pyruvate accepts hydrogen and is converted to lactate by the help of enzyme lactate dehydrogenase , again free NAD is released to continue glycolysis.
Hope I made it clear enough :)
Answer:
B.) Scrubbers
Explanation:
Scrubbers are used to remove poisonous gases from industrial emissions before they are released into the atmosphere.
These devices are air pollution control units in industrial power plants that uses liquids to absorb harmful gaseous industrial gases.
- Some of these gases are carbon monoxide, nitrogen oxides.
- This atomized liquid removes harmful gases
- The waste gas is brought into close contact with the liquid.
- Some of the gases will pass into the liquid.
- They are very effective in removing polluting gases from wastes.
