What should be in the body of an essay?
The main body of your essay should present a clear and logical response to the question. You should use focussed and connected paragraphs to further your argument. You should discuss and evidence a few key points in detail, rather than include lots of points that are dealt with in a superficial way.
What are 4 facts about your body system?
More interesting facts about the human body Every hour about 1 billion cells in the human body must be replaced. The average human head has about 100,000 hairs. The circulatory system of arteries, veins, and capillaries is about 60,000 miles long. The heart beats more than 2.5 billion times in an average lifetime.
Do humans have luciferin?
According to a study conducted in 2009 by Japanese researchers, human bioluminescence in visible light exists – it’s just too dim for our weak eyes to pick up on. “The human body literally glimmers,” the team from the Tohoku Institute of Technology wrote in their study published in PLOS One.
What is the human body capable of?
It is capable of creating life, surviving horrible diseases and accidents, and tasting all kinds of good (and equally bad) food). But human bodies are also susceptible to great tragedies, from freak accidents to medical mysteries.
What is red tide in California?
In simplest terms, a red tide is a “bloom” of phytoplankton. Phytoplankton are microscopic, single-celled plants that occur naturally in our coastal waters. Red tides are caused by a particular group of phytoplankton called dinoflagellates, which seem to prefer warmer and calmer waters.
Can I eat plankton?
Plankton has been considered as edible food for the human being in 2014 after more than 5 years of research and experiment, but actually at the moment it isn’t within everybody’s grasp. In fact it is sold wholesale at the price of 3000/4000 euro per kilo!
What is luciferin used for?
Luciferin is used, for example, in reporter gene assays to study gene regulation and function where expression of the luciferin-tagged reporter is a marker to indicate successful uptake of the gene of interest in recombinant DNA techniques.
How do you make luciferin?
1. Prepare a 200X Luciferin stock solution (30 mg/ml) in sterile water. Note: One can either reconstitute the entire 1.0 g of D-Luciferin in 33.3 mL of sterile water to make the 30 mg/mL (200x) stock solution, or reconstitute the quantity of D-Luciferin necessary for an individual experiment.
What is a human body?
Human body, the physical substance of the human organism, composed of living cells and extracellular materials and organized into tissues, organs, and systems. human body; human anatomy. Vintage anatomy charts of the human body showing the skeletal and muscle systems.
Is luciferin toxic to humans?
Luciferin is a low molecular weight organic compound that consists of a benzothiazole moiety attached to a thiazole carboxylic acid moiety. Luciferin is able to pass the blood brain barrier, the blood placenta barrier and the blood testis barrier, toxicity appears low.
What are blue tides?
The phenomenon is called ‘blue tide’, and appears when luminescent marine life make the sea appear a deep shade of blue. The spectacle occurs when phytoplankton (microscopic marine plants), commonly known as dinoflagellates, produce light through chemical reactions in proteins, said researchers.
What time does bioluminescence happen?
Bioluminescent displays are viewed best from a dark beach at least two hours after sunset, though visibility is not guaranteed.
Who named luciferin?
Why are the waves glowing at night?
The ocean can glow and glitter like the stars in the sky thanks to a natural chemical process known as bioluminescence, which allows living things to produce light in their body. The bioluminescent sea will glow when it’s disturbed by a wave breaking or a splash in the water at night.
Where does the water glow at night?
Mosquito Bay, better known as Bioluminescent Bay, is a tranquil, warm, shallow bay on the southern shore of the Puerto Rico island of Vieques. The bay is world famous for its extreme bioluminescence, declared as the brightest in the world.
Where are the waves glowing?
Here are several places around the world where you can go to see the waters glow:
- The Blue Grotto, Malta.
- Bioluminescent Bay, Puerto Rico.
- San Diego, California.
- Navarre Beach, Florida.
- Toyama Bay, Japan.
- Matsu Islands, Taiwan.
What causes plankton to glow?
What makes bioluminescent plankton glow? Bioluminescence is used as a defence mechanism to draw predators towards the creature trying to eat the plankton. The tiny flashes of light also disorientate and surprise the predator. These tiny organisms produce light using a chemical called luciferin.
Can human eyes glow?
All eyes reflect light, but some eyes have a special reflective structure called a tapetum lucidum that create the appearance of glowing at night. The tapetum lucidum (Latin for “shining layer”) is essentially a tiny mirror in the back of many types of nocturnal animals’ eyeballs.
How waves are formed?
Waves are created by energy passing through water, causing it to move in a circular motion. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.
Can you swim in bioluminescent water?
Although the bioluminescent plankton lives in all world`s oceans, the phenomenon is best seen in calm, warm waters at cloudy nights. Swimmers should keep moving as much as they can (or even dance and paint with the light) to surround themselves with a perfect ‘Avatar World’.
Is bioluminescence harmful to humans?
There is no reason to avoid this amazing phenomenon as not all bioluminescence is harmful. Bioluminescence is in fact a natural defense mechanism of many marine creatures including phytoplakton, squid, shrimp, and some fish.
What are the 12 body parts?
These different body systems include the skeletal, nervous, muscular, respiratory, endocrine, immune, cardiovascular/circulatory, urinary, integumentary, reproductive, and digestive systems.
What exactly is bioluminescence?
Bioluminescence is the production and emission of light by a living organism. If you’ve ever seen a firefly, you have encountered a bioluminescent organism. In the ocean, bioluminescence is not as rare as you might think. In fact, most types of animals, from bacteria to sharks, include some bioluminescent members.
Are glowing plankton dangerous?
The bloom can even make humans sick, Hu said. The dinoflagellates actually aren’t toxic themselves — until they begin chowing down, he said. Toxic algae is their food of choice, and as they eat, they release ammonia and other chemicals that poison the water around them.
Do we glow in the dark?
The human body literally glows, emitting a visible light in extremely small quantities at levels that rise and fall with the day, scientists now reveal. Past research has shown that the body emits visible light, 1,000 times less intense than the levels to which our naked eyes are sensitive.
Why is it called luciferin?
“Luciferin” got its name from the Latin word “lucifer” (meaning “light-bearing”), which is also a source of the word that is sometimes used as a name of the devil.
What causes bioluminescence?
Bioluminescence occurs through a chemical reaction that produces light energy within an organism’s body. For a reaction to occur, a species must contain luciferin, a molecule that, when it reacts with oxygen, produces light. Many organisms also produce the catalyst luciferase, which helps to speed up the reaction.
