Answer:

When temperature and wind speed are constant, but humidity increases, the rate of evaporation will decrease. When wind speed and humidity stay constant, and temperature increases, then the rate of evaporation will increase because warmer air can hold more water vapor than colder air.

Answer:

if the rate of evaporation reduces water cylcle will stops and amount of water present in the world will be increase.humifity will be more.

Answer:

The Cell Wall of plants are more geometrical, than animal cells. Plant cell wall are also stronger.

Plant cell is larger than animal cells

Plant cell have chloroplast while animal cells doesn't

Explanation:

Answer:

cell wall

Explanation:

Plant cells contain a cell wall while animal cells do not have a cell wall. By looking for the presence of a cell wall, students would be able to positively identify a cell as either plant or animal.

Answer:

Replication: it occurs in the S phase of the cecular cycle and the condensation of the chromosomes, the phase is M.

Answer:

sucrase:4

lipase:8

pepsin:3

trysin:8

pepsin would not work because it is alkalinic environment and it would become denature.

no because the enzymes will be denature

Explanation:

The CO2 Extinguisher Cannisters contain carbon dioxide in liquid form, and when the extinguisher is let off the liquid is released into the air neutralising the oxygen that the fire is feeding on, disabling the fires ability to spread.

i think its what you want :)

neutralising-make (something) ineffective by applying an opposite force or effect.

A

Explanation:

Cell Q also has a cell wall

Answer:

The onerous elements of organisms, like bones, shells, and teeth have a far better likelihood of changing into fossils than do softer elements. One reason for this can be that scavengers typically don't eat these elements. onerous elements conjointly decay additional slowly than soft elements, giving longer for them to be buried.

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.”

Answer:

Mutations can occur before,during and after mitosis and meiosis if a mutation occurs in cells that will make gametes by meiosis or during meiosis itself it can be passed on to off spring and contribute to genetic variability of the population.

may be this was ur answer of ur question.

Mutations and meiosis are in that they both produce genetic variation

in organisms.

Meiosis is a type of cell division that involves the production of sex cells or in sexual reproduction. They produce unique daughter cells and in situations where there is a mutation in this process, it is usually passed to the offspring which leads to genetic variation.

Mutations are also usually passed to the daughter cells as it occurs in their

cells during reproduction which makes it similar with meiosis in the area of

genetic variation.

The ozone depletion process begins when CFCs (chlorofluorocarbons) and other ozone-depleting substances (ODS) are emitted into the atmosphere. CFC molecules are extremely stable, and they do not dissolve in rain. After a period of several years, ODS molecules reach the stratosphere, about 10 kilometers above the Earth’s surface. CFCs were used by industry as refrigerants, degreasing solvents, and propellants.

Answer:

Ozone depletion occurs when chlorofluorocarbons (CFCs) and halons—gases formerly found in aerosol spray cans and refrigerants—are released into the atmosphere (see details below). ... CFCs and halons cause chemical reactions that break down ozone molecules, reducing ozone's ultraviolet radiation-absorbing capacity
