THIS ASSIGNMENT IS DUE IN 20 MINUTES HELP!!!!!! What causes the temperature to increase with height through the stratosphere and decrease with height through the mesosphere?
The temperature increases on the stratosphere with the altitude, given that absorption of the ultraviolet rays by the ozone.
On the stratosphere, the water vapor and the umidity are almost nonexistents and, in view of the absorption of ultraviolet rays by the ozon, the temperature increases, reaching 35,6º Fahrenheit. The ozone is a unusual type of oxygen molecule. In the stratosphere, the ozone appears on a large scale and warms it up by the absorption of the ultraviolet rays energy.
The temperature decreases in the mesosphere since there is no ozone and the amount of air is decreasing.
Within the mesosphere, temperature decreases with increasing height, due to decreasing absorption of solar radiation by the rarefied atmosphere and increasing cooling by CO2 radiative emission. The top of the mesosphere, called the mesopause, is the coldest part of Earth's atmosphere.

How will the increase in the tuna population affect the other populations? Be sure to explain whether the dolphin population, the squid population, and the herring population will change, and why.
Complete question:
Scientists have been studying four populations in one area of the Atlantic Ocean. In this area, both tuna and dolphins eat squid, and squid eat herring (a type of fish).
The data shows that recently the tuna population increased. How will the increase in the tuna population affect the other populations? Be sure to explain whether the dolphin population, the squid population, and the herring population will change, and why.
You will find the image in the attached files.
Answer:
Tunas´ population increasesSquids´ population decreases because more tuna eat themDolphins´ population decreases because there are fewer squids availableHerrings´ population increases because they do not suffer predation by squids.Explanation:
In the trophic web occurs a process of energy transference through different organisms placed at different levels. Each level feeds on the preceding one and becomes food for the next one. The first link is an autotroph organism or producer. The following links are the consumers: herbivores are primary consumers and feed on producers. Carnivores are secondary consumers and feed on herbivores, and so on. The last links are the decomposers, microorganisms that act on dead animals degrading organic matter.
If any of the links change their population size (increasing it or decreasing it), it affects the superior links and the immediately anterior link.
In the exposed example of the trophic web, tuna feeds on squids. If the tuna population increases in size, there will be more individuals feeding on squids. Squids will be affected because too many animals are eating them, and they will not have enough time to reproduce and recover the normal population size. The mortality rate by predation is higher than the natality rate, meaning that the squid population will decrease.
Dolphins also feed on squids. But as the tuna population increases in size, competition for squid prey will be higher. Both species (tuna and dolphins) will compete for food. But tuna will eat more squids, and hence, dolphins will be affected and decrease in population size.
Usually, herrings are eaten by squids. But as the squids' population decreases, herrings will not suffer from predation, and their population will increase in size.
So, to sum up:
Tunas´ population increasesSquids´ population decreases because more tuna eat themDolphins´ population decreases because there are fewer squids availableHerrings´ population increases because they do not suffer predation by squids.

Which of the following are biofuels? Select all that apply*
Coal
Petroleum
Natural gas
Ethanol
Biodiesel
Answer:
Biofuels have been around longer than cars have, but cheap gasoline and diesel have long kept them on the fringe. Spikes in oil prices, and now global efforts to stave off the worst effects of climate change, have lent new urgency to the search for clean, renewable fuels.
Our road travel, flights, and shipping account for nearly a quarter of the world's greenhouse gas emissions, and transportation today remains heavily dependent on fossil fuels. The idea behind biofuel is to replace traditional fuels with those made from plant material or other feedstocks that are renewable.
But the concept of using farmland to produce fuel instead of food comes with its own challenges, and solutions that rely on waste or other feedstocks haven't yet been able to compete on price and scale with conventional fuels. Global biofuel output needs to triple by 2030 in order to meet the International Energy Agency's targets for sustainable growth.

THE HIDDEN COSTS OF TURNING FOOD INTO FUEL
Explanation:
The biofuels are Natural gas, Ethanol and Biodiesel. These are all the correct options.
What are biofuels?Biofuels are the fuels derived from biological sources such a plants and algae rather than from the fossil fuels. They are considered to be a renewable energy source, as the raw materials used to produce them can be replenished relatively quickly.
There are several types of biofuels:
BioethanolBiodieselBiojet fuelBiomethaneOverall, the use of these fuels are considered to be a promising solution to reduce dependence on non-renewable fossil fuels and to reduce green house gas emissions in the transportation sector. Awareness should be created in the public for the utilization of the biofuels so that it is used more and more and reduce the pollution caused by fossil fuels.

What do your muscle cells do when they run out of oxygen for respiration?
Explanation:
When your muscle cells run out of o2 4 respiration, it relies on stored fat or lipids for energy..(glycolysis) ...
Normally this transition does not last long because muscles also depend on glucose for energy..
When muscle cells run out of oxygen for respiration, they switch to anaerobic respiration, producing lactic acid as a byproduct.
When oxygen runs gone, muscle cells switch to anaerobic respiration. Aerobic respiration generates ATP from oxygen. Muscle cells switch to anaerobic respiration during severe activity or low-oxygen settings.
Muscle cells use glucose to respire anaerobically. Glycolysis generates ATP, although less efficiently than aerobic respiration. Lactic acid, a consequence of anaerobic respiration, can build up in muscles and cause tiredness, discomfort, and burning.
Anaerobic respiration offers short-term energy but is unsustainable. Muscle cells will resume aerobic respiration to efficiently create ATP and remove lactic acid once oxygen is available.

when the environment changes more quickly than a species can adapt the species may become?
A)diverse
B)extinct
C)dominant
D)overpopulated
If conditions change faster than a species can adapt and if its members lack the characteristics necessary to live in the new environment, the likely outcome will be extinction, hence option B is correct.
How a species can adapt?Natural selection causes this to occur, the species progressively transform in nature through natural selection to fit the niche.
A species may persist for a very long period before going extinct if it develops strong environmental adaptation and the environment remains stable.
Shorter-lived species breed more frequently, and the swift sequence of generations makes it possible for genetics.
Therefore, adaptations develop through natural selection much more quickly in these species, hence option B is correct.

Higher wildlife extinction rates. ...
More acidic oceans. ...
Higher sea levels.
Explanation:
Answer:
Global warming and climate change are two of the most pressing issues facing our planet today. The increase in temperature and changes in weather patterns have caused a significant impact on the environment and the different regions of the world.
In the Arctic, the ice is melting at an alarming rate, leading to rising sea levels. This has devastating effects on the wildlife that depend on the ice for survival. Polar bears, for example, are struggling to find food as the ice they hunt on disappears.
In Africa, climate change is leading to droughts and food shortages. This is particularly devastating for the millions of people who depend on agriculture for their livelihoods. Without adequate rainfall, crops fail, leading to famine and displacement.
In Southeast Asia, rising sea levels and more frequent storms are causing coastal erosion and flooding. This is leading to the loss of land and homes, as well as damaging critical infrastructure such as power plants and hospitals.
Overall, global warming and climate change are causing significant damage to the environment and the people and animals that depend on it. Urgent action is needed to mitigate the effects of these phenomena and prevent further damage to our planet.

It takes 600 J of work to lifta crate straight up but 1,200 Jto pushthat crate up a ramp to the same height. What's the efficiency of the ramp?
Answer:
50 percent
Explanation:
The efficiency of ramp can be found by using this formula
(Output work/input work)*100.
Amounts of work to lift up = 600j
Amount of work bro take up to same height = 1200j
Efficiency of ramp = (600j/1200j) * 100
= 0.5 x100
= 50 percent
Therefore from the calculations above, the efficiency of this ramp is 50 percent
