Introduction Red Tide, commonly labeled as Harmful Algal Blooms (HABs), is a natural phenomenon that is caused by an explosion of algae in coastal waters. The algae are single celled protists; plant-like organisms. Because the algae reproduce expeditiously, they manage to alter the color of coastal oceans. However, the name "Red Tide" is a misnomer; many times, the ocean can be multiple colors, ranging from green to blue to yellow. Overall, Red Tide has many negative effects on the environment as
Abstract The purpose of this term paper is to provide information about the different kinds of algal blooms and their effect on our environment and ourselves. There are still a lot of things that are not known about the algal bloom phenomenon, and many different hypotheses have been presented to explain these. Throughout the course of this paper those hypotheses will be presented and discussed, allowing the reader to derive their own opinion about the origin of algal blooms and what will happen
cases. The algae bloom releases toxins when its in a high concentrated state into the ocean that the shellfish take in but they don’t die. Instead they concentrate all of it into their body’s in a small space and if a human eats the shellfish the human has a huge chance of dying because of the toxin. The algae bloom also affects fish because the fish cant absorb the toxins and survive like the shellfish and ,because of the toxins theres a ginormous amount of fish that are killed by the toxins and there
this matter. However information of the LD50 for mice is available the oral and iv dosages are 3–10 μg/kg and 3400 ng/kg respectively. e. If saxtoxin is such a powerful toxin in people who eat contaminated shellfish, why does the toxin not poison/kill the host shellfish? i. The host/shellfish must have adopted a sodium ion channel that saxitoxins cannot bind to. For example some puffer fish have undergone a mutation that changes the amino acid sequence that makes its sodium channel insensitive to
Protists and prokaryotes serve as the primal foundation for the evolution of life present on Earth today. This is exemplified through the endosymbiotic theory, which gave rise to eukaryotic cells, as well as development of photosynthetic processes in plants. Despite the two being quite similar, they also possess key distinguishing features. For instance, the primary difference is that prokaryotes are strictly unicellular organisms, meanwhile protists are able to assume a variety of both multicellular
