but the size varies according to an individual's age, health and size. The heart weighs 7 to 15 ounces.
Oil spill or a discharge from pipe from a factory or sewage system. Since this is a single point of origin water pollution, this type of water pollution furnish itself to relatively easy remediation.
What is point source water pollution?
Point-source water pollution is the one type of water pollution which is easy to recognize because it generates from a single source or event and affects a specific area.
The negative effects of single point origin is deteriorating water quality which damage the environment, health conditions.
Destruction of biodiversity is another negative effect of water pollution depletes aquatic ecosystems and prompt unbridled proliferation of phytoplankton in lakes called as eutrophication.
The solution to reduce water pollution is reduce carbon dioxide emissions to prevent global warming and acidification of the oceans. Another is to reduce the use of chemical pesticides and nutrients on crops.

I think I understand even without the picture. I'll add a picture of the Punnett Square filled in, but what you're crossing is
Tt x tt (heterozygous crossed with a homozygous recessive)
The ratio you get in the end is 2 heterozygous (Tt) and 2 homozygous (tt) offspring, so the ratio is 1:1.
So the percentage of offspring that are homozygous recessive is 50%.
In fact, there are bacteria that grow in all kinds of pH, from the most acidic to the bad alkaline. Depending on the pH at which they live, bacteria can be classified as neutrophil, acidophilic and alkalineophilic.
But in general, when we talk about bacteria that are present in foods, they tend to grow in a pH range between 5 and 9, so they are considered as <u>neutrophil</u>. This can vary by species and other factors such as temperature and available nutrients.
