Where is frost wedging most likely to occur?

Biology
2 answers:
denpristay [2]4 years ago

Answer:

C. A temperate region that experiences multiple freezes and thaws each year

Explanation:

Frost wedging is a form of physical weathering which involves physical breaking of a rock.

Frost wedging occurs in areas where there is extreme cold and rainfall round the year.

The repeated freezing and thawing of water that is found in the cracks of rocks referred to as joints, pushes the rock to the breaking point.

Answer:

C

Explanation:

Water ‘expands’ when its temperatures go below 4 degrees centigrade. Therefore, ice is larger in volume compared to liquid water. Therefore, when water gets into the crevices and cracks of rock in the ground, the cyclic thawing and freezing of the water put stress on the rock/ground hence wearing it and forming and even bigger gorges.

Which structure ATP or ADP contains more stored energy? Where is the energy stored
koban [17]
The ATP is the adenosine triphosphate. The ATP molecule has the three phosphate molecules attached with the adenosine. The ADP is the adenosine diphosphate. It has two phosphate groups. The number of phosphate molecules is responsible for the amount of energy in bonds. Hence the ATP molecule has the three phosphate group hence it has more stored energy as compared to the ADP molecule which has two phosphate group.

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.”

PLEASE HELP!! ASAP favorable adaptations are genetic mutations that
umka21 [38]

Answer:

[B] improve the organism’s chances of survival

Explanation:

Favorable adaptation are individual better suited to survive and reproduce in their environment. Meaning that will become more and more common in the population. Which also means they increase an organism's chances of surviving or reproducing, so they are likely to become more common over time.

Basically,  improve the organism's chances of survival and reproducing. As a result we can see that the best answer choices is [B] improve the organism’s chances of survival
