causes red tides?

Why crimson seas are not as unbelievable a sight as you might first think....


A red tide is the rapid accumulation of a mass of aquatic algae, made up of mobile single-celled microbes, known as dinoflagellates - meaning the nature of tail-like projections spreading them through water. Due to 'whipping whip'. Algae grow, or blossom, more rapidly than usual to consume more nutrients that have suddenly increased from the cool depths of the ocean below. The red color is down to the presence of a certain species of dinoflagellate, or phytoplankton. With more abundant diatom algae, dinoflagellates make up the majority of the plankton of the ocean. Despite the rather staggering appearance of a sea that has turned red, many algal flowers are actually completely harmless. However, you should not consume seafood after red tide as some phytoplankton may release harmful substances into the water. Some dinoflagellates can produce toxins when eaten by other creatures, and harmful substances are then concentrated inside the organisms that feed on them, and later any humans who feed on contaminated seafood. Billions of microscopic dinoflagellates in a red tide can also cause spectacular bioluminescence at night. One species in particular - Lingulodinium polydrum - can make its light from within. When the creature is jerked or collides with it

Some in the ocean, a chemical reaction occurs when an enzyme called luciferase and a substrate called luciferin, both contained within the organism, combine. It is a catalyst for a chemical reaction that releases a flash of blue light. When it happens millions of times simultaneously, the effect is quite remarkable for the audience.

What is comets?

चित्र
What is comets? Comets are objects made of ice, dust and rock in the solar system. They have a hard core and long tail of gas and dust. Every now and then they appear within sight of the Earth, before disappearing into deep space. TWO TAILS When a comet becomes close to the Sun, its ice melts and forms two tails: one made of gas and one made of dust. Halley’s Comet Halley makes a full circle around the comet The sun every 75 years, and it has been recorded by historians for more than 2,000 years. Beyklem  which tells the story of the battle of hasting shows it moving in the sky In the year 1066. Circling the sun Comets revolve around the Sun. Their tails are always away from the sun, but in slightly different directions. As the comet is closer to the sun, the tail grows longer.

How does the Arctic Ocean freeze?

How does the Arctic  Ocean freeze? Arctic sea ice is one that forms on the Arctic Ocean during the winter months. Pure water, which does not contain any other molecules, substances or impurities, freezes at 0 ° C (32 ° F). On the other hand, about 3.5 percent of the world's seawater contains dissolved minerals and salts. This additional material reduces the freezing point of seawater to about −2 ° C (28.4 ° F) because the freezing point depends on the number of molecules present in a solution, as well as the type of molecule. During the winter months, when air temperatures in the Arctic begin to drop dramatically, a deep layer of seawater begins to develop minuscule ice crystals; This dirty water is called Fragile Ice. Another drop in temperature causes Friesil's ice to become thick. Pockets of salty slash accumulate until they become so heavy that they begin to sink. This leaves the top layer of icy crystals with a significantly lower salt content. The freezing poi...

What is the event horizon ?

What is the event horizon?  Black holes have three basic elements. In the middle of a black hole and to an infinite density is a singularity made of stellar matter. Outside the singularity is the inner space of the black hole, where the laws of physics as we know it are bent and broken, and where space and time are stretched and constricted Putty.  If your spacecraft has entered the interior of a black hole, it is too late for you. You are crossing the third component: the event horizon. It is also known as the Schwarschild radius, the part that tells us where the black holes are outlined in black. This indicates no return for anything falling next to it, as it requires a faster travel than the speed of light to cross again, as far as we know it is impossible. . No horizon is attributed only to black holes' just a remarkable phenomenon that they possess. According to some principles To control the expansion of the universe, there are regions that will never be obse...
