Answer:
These fuels are very efficient, it means that fossil fuel sources (oil, natural gas and coal) have high energy conversion rates, thereby they enable to generate important amounts of energy.
Explanation:
It has been shown that the overall efficiency of the conversion of fossil fuels to electricity is approximately 40%, while 60% of the energy produced is wasted during the process of combustion. However, it is important to note that the efficiency of renewable energies (i.e., geothermal, solar, hydroelectricity, wind and biomass) have been considerably increased in the last years.

What are the main points of the cell theory of life
The main points of the cell theory are:
1. The cell is the SMALLEST living unit of life.
2. The cell is so small is it is not visible to the naked eye.
3. The shape of the cell can vary based on the different lifeforms they are in.
4. The size of the cell also varies.
5. All living organisms or lifeforms are made from cells.
6. Cells originate from a pre-existing cell, in multicellular lifeforms, then the pre-existing cell will divide into many other cells with the process repeating.
7. All cells retain the same properties, such as growth, respiration, and etc.

What is ecosystem?An ecosystem have each and every organism and the relation between physical environment by which they interact. The function of ecosystem is to satisfy the need of humans by supplying them services and goods from nature.
Ecosystem is the branch of science which deals with the study of relationship between living organisms and natural phenomena. Ecosystem is the system in which both living as well as nonliving organisms are present in a particular location.
There are various types of ecosystem such as Grassland ecosystem, Tundra ecosystem, Desert ecosystem, Forest ecosystem. Biodiversity is all the different kinds of life living in a particular area like the varity of animals, plants, fungi and microorganisms like bacteria and virus that plays a major role in framing of natural world usually three levels of biodiversity are observed and these are genetic species, and ecosystem diversity.
Therefore, According to the graph the number goes up of turtles over these five years. Thus, option A is correct.

Calculate the percent increase in population between year 1 and year 2, year 2 and year 3, and year 3 and year 4. Round up or down to the nearest whole percentage.
Answer:
Explanation:
Please provide the population to enable me do the calculation
Answer:
Percent increase between years 1 and 2:
(5,780 – 3,845) ÷ 3,845 = 0.50 = 50% increase
Percent increase between years 2 and 3:
(15,804 – 5,780) ÷ 5,780 = 1.73 = 173% increase
Percent increase between years 3 and 4:
(52,350 – 15,804) ÷ 15,804 = 2.31 = 231% increase

What factors do you think might be making it difficult for farmers to treat this disease in their banana plants?
Answer: Panama disease. It's a fungus – known as fusarium wilt – that infects the root system of banana plants and, eventually, kills the plant. There is no cure for the disease, and when one plant is infected, an entire plantation can easily be brought down.

What happens to the second and third stages when they run out of fuel?
Answer:
When the first stage separate, then it will not descend further and it will fall away. It would not be able to launch into air.
The first stage actually help to release it from shell, the first stage of multistage rocket help it to sprout.
If the first stage runs out of the fuel, then there will be no combustion in rocket and it will not ascend further into next stages.
If the second and third stage run out of the fuel then the next 4th and 5th stages will happen to a cessation and there will be a likelihood for it to fall down to earth.

How do subduction zones form
Answer:
A subduction zone forms when continental crust and oceanic crust collide. The continental crust is thicker and more buoyant than the oceanic crust so the oceanic crust subducts beneath the continental crust. ... Volcanoes associated with subduction zones generally have steep sides and erupt explosively.
Explanation:
Answer:
possible answer from edge
Explanation:
Subduction zones are formed at convergent boundaries when tectonic plates collide. If one of the plates slides under the other plate, a subduction zone is formed

Answer:
This a process of ecological succession that occurs in every environment.
Explanation:
The first organism which starts growing on the rocky surface are the mosses and grasses. We called it primary succession because mosses and grasses are the first organisms which lives on rocky surface. After some time, these mosses disappear or removed due change occur in the environment and new species such as higher plants start growing on these surface. The mosses die and provide nutrients for the higher plants. We called it secondary succession because the mosses are removed and higher plants takes their place.
Select a type of renewable energy. Compare it to fossil fuels by explaining two pros and two cons for its implementation on a large scale. Maintain an environmental focus (do not just give economic reasons).
Answer:
Bio gas
Explanation:
Bio gas is gotten from the anaerobic breaking down of biomass especially animal waste.
PROS:
A. it is renewable: biogas is renewable and has an endless supply of material since animals are the main source when compared to fossil fuels.
B. It doesn't involve a rigorous mining exersice to get to like fossil fuels and it is in accessible abundance.
CON:
A. A lot of waste is needed for the product of biogas and the final waste (sludge) from the production process can be a huge problem to dispose off.
B. Some of the gases liberated in the manufacturing process are greenhouse gas, especially methane. These gases if let out, will contribute immensly to global warming.
What might be some possible issues of increasing heat waves?
Answer:
Extreme heat can cause cramps, swelling, and fainting. Heat waves kill more Americans than other natural disasters such as floods, lightning, tornadoes, and hurricanes. Heat exhaustion is a relatively common reaction to severe heat and can include symptoms such as dizziness, headache and fainting. But when sustained heat waves hit a region, the other health ramifications can be serious, including sunstroke and even major organ damage due to heat. Heat stress, or when too much heat, is absorbed by the body can cause extreme exhaustion but can also mess with our thinking, making things like everyday tasks and simple math a little harder to do.
If the adenine in the 15th position of the sequence is changed to a guanine, the person does not have CF. However, if the thymine in the 14th position is changed to a cytosine the person does have CF. What are some reasons this might occur?
Answer:
Explanation:
Mutation is a sudden heritable change in the genome of an organism.
Substitution is a form of mutation whereby a base pair is been substitued for by another base pair resulting in a serious damage.
Codon are three alphabeth coding for a particular amino acid.
When substitution occurs in a base pair and the replacement forms a protein that has the same function as the one that was removed there will be no observable in the phenotype. Hence, If the adenine in the 15th position of the sequence is changed to a guanine, the person may not have cystic fibrosis.
But when a particular base pair is substituted for and an entirely new protein or amino acids results with a different functions and structure it could lead to a serious damage or healthy issue. Hence, If the adenine in the 15th position of the sequence is changed to a guanine, the person does have cystic fibrosis.

how would you use the scientific method to answer this question: do mice live longer when they are fed high-sugar diets
Answer:
The question: Do mice live longer when they are fed high sugar diets?
Hypothesis: There are two hypothesis the null hypothesis which we assume is correct, it states that a high sugar diet will have no effect on the life span of a mouse and an alternate hypothesis that we accept if evidence shows that sugar does increase the life span if mice. It says a high sugar diet does incerease the life span of mice.
Prediction: Assume that the null hypothesis is correct. High sugar diets will not increase the life span of the mice.
Collect data through experimentation. Use some mice as a 'control'. These mice will not undergo any changes but will be kept for comparison. Expose some other mice to high sugar diets and the compare the outcome with the 'control' mice.
Analyzing: From the experiment this you can choose which hypothesis you are going to accept. I.e. null: no change or alternate: there was a change and do some extra research to back up your hypothesis.
