How do electrons behave in the atom?

Biology

When the electron wavefunction is bound in a stable state in an atom it stretches into a 'orbital' form. There was a mistake. When attached in a stable atomic state, an electron often acts like a three-dimensional oscillating wave, i.e. the orbital vibrates. It's sort of like a vibrating chord.

If a blood exposure occurs while providing a consumer service, the practitioner must disinfect all equipment, instruments, and surfaces with a bleach solution or a disinfectant that has been registered by the EPA that is bactericidal, virucidal, and fungicidal.

Disinfectants are chemicals that kill microorganisms in liquid form. To kill the germs that are present on the surfaces of non-living things, they are typically administered to those surfaces. In order to eliminate infectious microorganisms, disinfectants are typically used in hospitals, kitchens, restrooms, etc.

Disinfectants come in a variety of forms, and the type to employ depends on the type of bacteria involved. When there is a chance that a surface has been contaminated with infectious agents, disinfectants are utilised.

The disinfectant phenol is used to denature and coagulate the proteins of microorganisms. In domestic settings, phenol is used to clean floors. The efficiency of phenol has so always been likened to disinfection.

grigory [225]

1. The correct answer is option (B) Component 3 and 4 only. The difference between the plant cell and an animal cell is the presence of the cell wall and the plastids called the chloroplasts in the plant cells. Cytoplasm is the jelly like substance present in both the plant cells and animal cells. Nucleus is the brain of the cell regulating the metabolic activities of the plant and animal cell. Cell membrane is the semi-permeable membrane covering all the cells.

2. The correct answer is option (D) Biomagnification leads to higher toxicity in tuna. Biomagnification is the accumulation of toxic substances at different tropic levels of the food chain. Fishes are a target of biomagnification due to the intake of the methyl mercury in them.

3. The correct answer is option (B) 1. Prokaryotic cells 2. Eukaryotic cells. The image 1 is a prokaryotic cell and the image 2 is a eukaryotic cell. Prokaryotes are the cells with primitive nucleus. They do not have a well-defined nucleus and the membrane bound organelles. Eukaryotes are the cells with a well-defined nucleus and all the membrane bound organelles.

What are some ways you can reduce the number of fishnets in the ocean?
Juliette [100K]

Answer:

August 11, 2014 — Six years ago, the Norwegian coast guard filmed a Scottish fishing vessel riding gray swells, dumping 5 metric tons of dead fish back into the North Sea. Over the European Union catch quota, and so unable to keep all the fish they’d caught, the fishermen had to ditch some. To the Norwegians, who aren’t part of the EU and hold a strict discards ban, the waste was shocking.

When this news reached Dan Watson, a young British designer, it became the inspiration for SafetyNet, an ocean fishing net that allows certain fish to escape via lighted rings, offering more catch selectivity. The Scottish fishermen’s predicament, he believed, was driven by their lack of control. “There can be no villains, there can be no victims, there are just problems,” Watson says. “I started this project because I wanted to go some way towards solving that problem.”

Bycatch can result in overfishing, reduces the population of species that might already be endangered and, on the largest scale, interrupts food chains and damages whole ecosystems.

Watson joins a growing number of innovators designing more selective fishing gear to reduce bycatch — the unwanted fish, dolphins, whales and birds that get scooped up by longlines, gillnets and trawlers each year and then discarded. Globally, the amount of marine life that is wasted or unmanaged — which makes it potentially unsustainable — forms about 40 percent of the catch. “The way we catch now is to catch everything, decide what we want to keep, and discard the rest,” says Martin Hall, head of the bycatch program at the Inter-American Tropical Tuna Commission, which regulates tuna fishing in the eastern Pacific Ocean. Bycatch can result in overfishing, reduces the population of species that might already be endangered and, on the largest scale, interrupts food chains and damages whole ecosystems. It also amounts to an enormous waste of valuable fish protein.

To designers building better nets and lines, bycatch isn’t viewed as an inevitability, but as something we can phase out, piece by piece. It’s also seen as a battle that needs to be fought alongside fishermen, not against them.

Rethink the Game

Speaking from his trawler, the 45-foot Proud Mary, off the coast of Massachusetts, one such fisherman, Christopher Brown, says that over the years, fishermen have had to “rethink the game.” Brown operates a fishery that’s almost completely free of discards; is the board president of the Seafood Harvesters of America, an organization representing stewardship-minded fishermen; and has designed a squid net that reduces bycatch. The net contains an escape route at its base that exploits the bottom-dwelling behavior of unwanted flounder, encouraging them to flee the net through this gap. “We need to look at things entirely differently than we have in the last 30 years,” Brown says — and new gear is part of that equation. “It’s a matter of enlightened self-interest.”
