especially the impact on the water ecosystem. BecauseSTPP is usually used in detergents and cleaner, it is discharged into the water body to cause nutritionalization. This is a process characterized by excessive nutrients. The inflow of this nutrients promotes the rapid growth of algae, leading...
LIFE cycles (Biology)GENETIC polymorphismsHAPLOGROUPSHydrozoans are widely known for their complex life cycles. The life cycle usually includes an asexual benthic polyp, which produces a sexual zooid (gonophore). Here, we performed an extensive analysis of 183 specimens of the hydr...
CVID (Common Variable Immunodeficiency) is a primary immune deficiency disease. It is characterized by low levels of protective antibodies, which causes an increased risk of infections. Many people with CVID carry a DNA variation or a polymorphism in a gene known as TACI. The signs and symptoms ...
Sea anemones also reproduce in a similar way to jellyfish. The first step of reproduction is sexual where the gametes fuse to form a polyp. The polyps reproduce asexually by budding. Budding in Corals Corals are a vast colony of living organisms. They are marine invertebrates and reproduces ...

Keep an open mind. Think about versatility You may agree that the first consideration governing the purchase decision about a pump in the chemical and process industries should be fitness-for-purpose. How safely and efficiently it will do the job for which it is required. 年份: 2008 ...
The biology of aging in humans and other organisms is still rich in mystery, but scientists have identified some potential physiological characteristics and processes that may dictate a longer life for certain creatures. At a basic level, a slower metabolism, such as that exhibited by some cold-...
