CATDOLL : CATDOLL: What algae causes red tide?

1. What algae causes red tide?

Harmful algae cause marine red tides, most of which are dinoflagellates, followed by diatoms, cyanobacteria, golden algae, cryptoalgae and protozoa.

Organisms that can reproduce in large numbers and cause red tides are called red tide organisms, including plankton, protozoa and bacteria. Among them, dinoflagellates are the most toxic and harmful red tide organisms, followed by diatoms, cyanobacteria, golden algae, cryptophytes and protozoa.

Among the 63 species of plankton known as red tide organisms, there are 24 diatoms, 32 dinoflagellates, 3 cyanobacteria, 1 golden algae, 2 cryptophytes, and 1 protozoa. In China, there are 25 species of red tide organisms that have been documented.

The remaining 38 species are distributed in China's waters, but have not yet formed red tides. Therefore, the distribution of red tide organisms in the sea area does not necessarily mean that red tides will occur. It depends on whether their density can reach a level sufficient to change the color of the water in the local sea area.

Cerebral paragonimiasis, caused by adult worms invading and migrating into the brain; 5. Cerebral hernia, caused by hernial protozoa blocking the capillaries in the brain.

6. How are the causes of epilepsy classified?

The causes of epilepsy can be divided into 1. non-specific stimulation-inducing factors, which are often induced by physiological factors, environmental factors and gonadal function; 2. specific stimulation-inducing factors, which are certain special factors that can trigger an attack, such as light-induced epilepsy, audiogenic epilepsy, proprioception-induced epilepsy, visceral sensation-induced epilepsy, and others, such as calculation-induced epilepsy, reading-induced epilepsy, writing-induced epilepsy, etc. 3. high-level psychological activity-induced epilepsy 4. self-induced epilepsy 5. conditioned reflex epilepsy.

7. What are the diseases that cause blindness in pigs?

That's the eye band. Use a needle with thread to thread the long flesh and pull it up, cut it off with scissors, and then add a little salt water to the eye. It will be healed in a few days.
