<span>Yeasts are unicellular microorganisms that use sugar as food releasing carbon dioxide. With the released gas increases the pressure when oxygen is present inside the bottle, yeasts grow by the breathing process are consuming oxygen and producing carbon dioxide. And when the oxygen is finished the yeasts change to anaerobic metabolism and the degradation of sugar occurs by fermentation that produces greater amounts of alcohol and gaseous carbon dioxide.</span>
In stem cell transplants, stem cells replace cells damaged by chemotherapy or disease or serve as a way for the donor's immune system to fight some types of cancer and blood-related diseases, such as leukemia, lymphoma, neuroblastoma and multiple myeloma. These transplants use adult stem cells or umbilical cord blood.
Increasing ocean acidity impact the mechanism of natural selection by
leading to increased random mutations and unfavorable traits.
<h3>Effects of Ocean acidity</h3>
Ocean acidity is harmful to organisms present and gives rise to the following:
This could be as a result of excess Carbon dioxide or acidic contents in the
ocean. This negatively impacts organisms and alters the genetic constituent
thereby leading to mutations and passing on of unfavorable traits to
offsprings.

Answer:
Domesticating plants and animals
Fear of snakes and spiders
Social roles and cooperation
Explanation:
The reason that we inherited these traits from our ancestors is that they confer an advantage in the environment in which we live. This process occurred through natural selection pressures that power evolution. Individuals that bore these traits had higher chances of reaching reproductive age and passing down their genes. Individuals without these traits died sooner hence their genes reduced with every generation.
