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?
Answers
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.

Electromagnets is to be controlled by controlling the electric current. If the current is turn on, also turns the magnetic field on while on the other hand, If the current is turn off, also turn off the magnetic field. The quantity of current flowing through the coil can also control the strength of the electromagnetic field around that coil.
Which of the following are biofuels? Select all that apply*
Coal
Petroleum
Natural gas
Ethanol
Biodiesel
Answers
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.

when the environment changes more quickly than a species can adapt the species may become?
A)diverse
B)extinct
C)dominant
D)overpopulated
Answers
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.

Answers
Answer:
Species taxon includes the most specific characteristics.
I hope this might be the answer for ur question ☺️
The most specific characteristics are seen in Species Taxon.
What is Taxon?Taxon is defined as the unit of taxonomy which are arranged in a hierarchy from kingdom to species.
The taxonomic classification was given by Carlos Linnaeus who is known as the Father of Taxonomy.
In descending order it is classified as:
Kingdom - Phylum - Class - Order - Family - Genus - Species
A taxon is usually known by a particular name and given a particular ranking and is given formal science name, its use is then governed by one of the nomenclature code specifying which scientific name is correct for particular grouping.
What is species?Species are the most specific taxon which share common traits and characteristics closely to each other and are capable of interbreeding.
It is the largest group of organisms in which any two individuals of the appropriate sexes or mating type can produce fertile offspring through sexual reproduction.
Types of species:
- Typological/ Morphological Species:
Individuals are having fixed properties as can be easily recognized by the modern taxonomist.
- Recognition/ Cohesion species:
Group of sexually reproducing organisms recognizing one another as potential mates.
- Genetically similar
- Phylogenetic/ Cladistics species:
These are the smallest group based on unique combination of character states in comparable individuals.
- Evolutionary species:
Set of species adapted to a particular set of resources called niche in the environment.
- Genetic Species:
Set of genetically isolated interbreeding populations.

The temperature is some 30C. The humidity stifling, the noise unbearable. In a yard between two enormous tea-drying sheds, a number of dark-skinned women patiently sit, each accompanied by an unwieldy looking cloth sack. They are clad in colourful saris, but look tired and shabby. This is hardly surprising - they have spent most of the day in nearby plantation fields, picking tea that will net them around two cents a kilo - barely enough to feed their large families.
Vivek Baid thinks he knows how to help them. He runs the Mission for Population Control, a project in eastern India which aims to bring down high birth rates by encouraging local women to get sterilised after their second child.
As the world reaches an estimated seven billion people, people like Vivek say efforts to bring down the world's population must continue if life on Earth is to be sustainable, and if poverty and even mass starvation are to be avoided. There is no doubting their good intentions. Vivek, for instance, has spent his own money on the project, and is passionate about creating a brighter future for India.
But critics allege that campaigners like Vivek - a successful and wealthy male businessman - have tended to live very different lives from those they seek to help, who are mainly poor women.
These critics argue that rich people have imposed population control on the poor for decades. And, they say, such coercive attempts to control the world's population often backfired and were sometimes harmful.
Population scare
Most historians of modern population control trace its roots back to the Reverend Thomas Malthus, an English clergyman born in the 18th Century who believed that humans would always reproduce faster than Earth's capacity to feed them.
Giving succour to the resulting desperate masses would only imperil everyone else, he said. So the brutal reality was that it was better to let them starve.
Rapid agricultural advances in the 19th Century proved his main premise wrong, because food production generally more than kept pace with the growing population.
But the idea that the rich are threatened by the desperately poor has cast a long shadow into the 20th Century.
From the 1960s, the World Bank, the UN and a host of independent American philanthropic foundations, such as the Ford and Rockefeller foundations, began to focus on what they saw as the problem of burgeoning Third World numbers.
The believed that overpopulation was the primary cause of environmental degradation, economic underdevelopment and political instability.
Massive populations in the Third World were seen as presenting a threat to Western capitalism and access to resources, says Professor Betsy Hartmann of Hampshire College, Massachusetts, in the US.

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?
Answers
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

What do your muscle cells do when they run out of oxygen for respiration?
Answers
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.

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.
Answers
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.

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.
