A common way that humans pollute water is through the addition of nutrients (fertilizers and sewage) to water as nonpoint source pollution. These added materials are full of nitrogen and phosphorus, two nutrients that encourage the growth of aquatic producers, such as algae.
Answer:
Epididymis
Explanation:
From the testes, the sperms travel to the epididymis. These structures can be found resting on top of each testes. Fresh out of the testes, sperms are not yet matured and this is where the epididymis takes over. The sperm are stored here and this is where sperm matures. From here, the sperm moves into the vas deferens.
The water may be polluted and the wetness of the dirt may not be suitible for numerous plants
Polycythemia is defined an abnormal increase in the number of circulating red blood cells. It is mainly caused by a cancerous condition known as myeloproliferative disorder or due to a low supply of oxygen to body tissues usually due to living in high altitude areas and the body tries to compensate by producing more red blood cells to increase oxygen carrying capacity of the blood
Normal blood count values in a male adult is 4.7 to 6.1 million cells/mcL, while in a female adult it is 4.2 to 5.4 million cell/mcL.
If this blood cell count is significantly higher then these values, and remains there or continues to rise, over a given period of time, accompanied with some specific symptoms, then polycythemia is suspected.
Fossils, homologous structures, vestigial structures, biochemical comparisons, and similarities between developing organisms(embryology).
