Air pressure is caused by the air molecules around us. Air particles are always in random and continuos motion, bombarding each other in random direction. As air particles collide they create pressure.
Alcohol is a fuel that can be burned.

What do you mean by fermentation?
The metabolic process of fermentation alters the chemical composition of organic substrates through the action of enzymes. The process of generating energy from carbohydrates without the presence of oxygen is expressly stated as such in biochemistry. If the action of microbes produces the intended alteration to a food or beverage, it may more broadly refer to any process utilized in food production. Zymology, or fermentation science, is a field of study. The primary mechanism by which bacteria manufacture adenosine triphosphate is fermentation, which involves the anaerobic degradation of organic molecules (ATP).

The fusion of two parents' genetic material is understood as sexual reproduction while asexual reproduction yields genetically similar offspring to the same parent.
<u>Asexual Reproduction:</u>
This way all the prokaryotes and other eukaryotes produce offspring. There are a variety of different asexual reproductive practices. These comprises of binary, fragmentation, and budding fission.
- The binary fission appears when a parent cell wants to split into 2 separate daughter cells of the same diameter. For an instance, protozoa reproduces in the same way.
- Fragmentation happens when a parent entity divides into small parts or fragments, and each segment grows into a recent organism. Starfish, that way replicate.
- Budding happens when a parent cell develops a bud close to a bubble. When growing and developing, the bud remains connected to the parent cell. This get detached from the parent cell when the bud is completely grown, and becomes a new entity. It is common in hydra and yeast.
<u>Sexual Reproduction:</u>
- A reproductive process which comprises haploid female gamete fusion, i.e. egg cell and haploid male gamete i.e. sperm cell.
- That implies they only include half the number of chromosomes contained in other species cells. A form of cell division named meiosis creates gametes.
- These gametes are fused at fertilization which results in the production of a diploid zygote having the chromosome double of gametes.
