Answer:
Can hydrogen peroxide be broken down by catalyst other than those found in a living system? Hydrogen peroxide can be broken down by manganese dioxide because it has catalytic properties. It is unstable which makes it very reactive. ... Sand however is not able to break it down
Explanation:
because it contains no catalytic properties
Manganese dioxide, which has catalytic properties, can degrade hydrogen peroxide. Because it is unstable, it is extremely reactive. It even degrades when exposed to light.
What is a catalyst?A catalyst is a substance that accelerates or reduces the temperature or pressure required to initiate a chemical reaction without being consumed in the process. Catalysis is the process of facilitating a reaction by adding a catalyst.
Hydrogen peroxide is one of the cleanest and most versatile chemicals available, decomposing to produce only oxygen and water (disproportionation).
The catalytic decomposition of hydrogen peroxide allows for the use of various catalysts to speed up the decomposition process.
Another consideration is that catalase is an enzyme that degrades at higher temperatures. The activation energy of the reaction changes as the catalyst decomposes.
As a result, the reaction will slow down. Manganese dioxide, on the other hand, does not decompose even at higher temperatures.
Thus, it can be concluded that hydrogen peroxide be broken down by catalysts other than those found in a living system.

Explanation:
A.
The transpiration stream that passes through a plant may follow an apoplastic route, with low resistance to flow, or a cell-to-cell route, in which cellular membranes impede water flow. However, passage of water through membranes can be facilitated by aquaporins thereby decreasing resistance. We investigated the relationship between transpiration, which can be down-regulated by abscisic acid (ABA) or by high humidity, and the osmotic water permeability (Pos) of protoplasts. By using leaf protoplasts of wild-type (wt) Arabidopsis thaliana plants and of mutants that are low in ABA (aba1) or insensitive to ABA (abi1 and abi2), we found that protoplasts from aba1 and abi mutants have very low Pos values compared with those from wt plants when the plants are grown at 45% relative humidity. High values of Pos were found 3 h after the addition of ABA to the culture medium of aba1 plants; addition of ABA to abi plants did not restore the Pos to wt levels. There was no such increase in Pos when excised leaves of aba1 plants were treated with ABA. When the transpiration stream was attenuated by growing the plants at 85% relative humidity, the Pos of protoplasts from all plants (wt and mutants) was higher. We suggest that attenuation of the transpiration stream in whole plants is required for the up-regulation of the Pos of the membranes, and that this up-regulation, which does not require ABA, is mediated by the activation of aquaporins in the plasma membrane.
B.
The influence of abscisic acid (ABA) on carbon metabolism, rate of photorespiration, and the activity of the photorespiratory enzymes ribulose bisphosphate oxygenase and glycolate oxidase in 7-day-old barley seedlings (Hordeum vulgare L. var. Alfa) was investigated. Plants treated with ABA had enhanced incorporation of labeled carbon from 14CO2 into glycolic acid, glycine, and serine, while 14C incorporation into 3-phosphoglyceric acid and sugarphosphate esters was depressed. Parallel with this effect, treated plants showed a rise in activity of RuBP oxygenase and glycolic acid oxidase. The rate of photorespiration was increased twofold by ABA treatment at molar while the CO2-compensation point increased 46% and stomatal resistance increased more than twofold over control plants.

How did the temperature relate to the “recommended temperature limit” (solid horizontal red line)?
Someone please just explain this question
Answer:
The “recommended temperature limit” indicates limit of the temperature that is good for our world.
Explanation:
The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the concentration of carbondioxide gas in the atmosphere increases due to this increase temperature..

Select one:
O a. Farm A is a free pasture farm for cattle, whereas Farm B is a free-range farm for poultry.
O b. Farm A is a cage-free farm for poultry, whereas Farm B is an industrial poultry farm.
O c. Farm A is a grass-fed pasture for beef production, whereas Farm B is a traditional
concentrated animal feedlot for cattle.
ction, whereas Farm B is a cage
O d. Farm A is a concentrated animal feedlot for beef
free farm for poultry.
Answer:
b. Farm A is a cage-free farm for poultry, whereas Farm B is an industrial poultry farm.
Explanation: the average days in any 12-month period suggest that farm b cages while farm a does not. The antibiotic usages for farm b also suggest it is an industrial (caged) farm because most cage-free and non-industrial farms do not rely on heavy use of antibodies.
The Farm A is a cage-free poultry farm while Farm B is an industrial poultry farm.
Farm A:
The caged day are zero means all birds can move freely in the farm area.They are not eat antibiotics to avoid infection.Farm B:
Most of the time in year, birds are caged. They fed antibiotic to all to avoid infection in the cage.Therefore, the Farm A is a cage-free poultry farm while Farm B is an industrial poultry farm.

A researcher found that the wild species of almond trees contains a chemical called amygdalin.
This chemical is converted into cyanide inside the human body and can be lethal. The researcher
found that a single gene mutation in some of the wild almond trees resulted in a variety that no
longer produced the chemical amygdalin. This variety of almond is largely harvested for human
consumption. Based on the study, the researcher claimed that some mutations are beneficial in
nature. Was the claim made by the researcher correct? Why or why not?
a) Yes. The mutated variety of almond was edible.
b) No. Not all almond trees produced seeds that were edible.
c) No. The mutation did not affect all varieties of almond trees.
d) Yes. Almond trees with amygdalin grew only in forests.
Answer:
a) Yes. The mutated variety of almond was edible.
Explanation:
Yes, the claim made by the researcher is considered correct because the mutation removes the amygdalin chemical from the almond so these almonds are now safe for eating. This removal only occur through mutation. Mutation is the sudden change occur in the DNA of cell that leads to different functions occur in the body so we can say that some mutation that is occur in organisms are beneficial.

Explain why parallax was a problem in proving the heliocentric model of the solar system.
Copernicus himself asserted that the absence of parallax meant that the stars were far beyond the planets. The failure of heliocentrists to detect it proved nothing, whereas a successful detection would be strong evidence for heliocentrism.
What is heliocentric model?The astronomical model in which the Earth as well as planets revolve around the Sun at the center of the universe is known as heliocentrism. Historically, heliocentrism was opposition to geocentrism, which centered on the Earth.
Galileo wanted to believe that his new invention, the astronomical telescope, could assist him in proving that the Sun was the center of our solar system and that Earth was only one of many planets orbiting our star.
Copernicus himself claimed that the lack of parallax indicated that the stars were far beyond the planets.
Failure to detect it by heliocentrists proved nothing, whereas successful detection would be strong evidence for heliocentrism.
Thus, parallax was a problem in proving the heliocentric model of the solar system.

I would prefer to have city water because you don't have to worry about it getting polluted unlike well water. The city water is maintained by the city while with the well water, you maintain it yourself. Even though it can be pricey, most people live in the city anyway, so there is easier access to it.
Explanation:
Answer:
Well Water
Explanation:
I would prefer well water, because city water had a lot of chemicals, and city water filters out minerals that are good for the body. Also, well water tastes ten times fresher than city water. Also, well water is easy to obtain if you already have a well, all you have to do is wither pump it up, or use a basket to scoop some out.
