The pH level of a cleaning product can vary depending on what you need. However, the most products would have a pH higher than 7 because anything above 7 will not be acidic but basic. Basic products tend to be more effective when cleaning.
Point source means: the pollution that comes from a single point (examples)
Sewage pipes releasing sewage into a ditch
Smokestack style factory chimneys
Oil pipes
Pollution which is caused by rain fall or snow melting into the ground. As the runoff moves, it picks up and carries away natural and human made pollutants, Finally reaching a lake, river, ocean, groundwater.
Answer:
Because offspring with two parents will share half of each parent's DNA.
Explanation:
Sex cells contain half of the genetic information of an organism's regular cells. This is because a sexually-produced organism will be unique; it will share genetic information with both of its parents, rather than be identical to its bearer (like an asexual organism would be). When a sex cell meets another sex cell, their DNA will meet as well and change/adapt to suit the organism. If a sex cell had all the information needed to create an embyro, instead of half, which requires another cell's information to fill the DNA void.... well, it would just do it.
Catabolic reactions use energy to synthesize large molecules from small molecules.
<h3>What is a catabolic reaction?</h3>
The Catabolic reaction is the action of the set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy or used in other anabolic reactions. Catabolic reactions are a type of metabolic reaction that takes place within a cell. An example of a catabolic reaction is the process of food digestion, where different enzymes break down food particles, so they can be absorbed by the small intestine.
