why are fossil fuels supplies limited
Answer: The coal, oil and natural gas we are consuming now are the remnants of plants, trees and animals that were living hundreds of millions of years ago. There is no way to replace them, as conditions on Earth are much different now.
Explanation: Mines and wells are being depleted much faster than they were a hundred years ago when demand was much less-- fewer people, fewer cars, fewer planes. . . and people believed there was an endless supply. Many of those mines and oil wells are now empty.

How do ecosystems return to normal after a flood?
This really depends on the ecosystem, as each ecosystem may respond differently.
Explanation:
How an ecosystem responds is going to depend on the ecosystem, as each ecosystem may respond differently, and also on the extent and magnitude of the natural disaster. It takes ecosystems a long time to return to semi-normal conditions it can take up to 200 years for a forest to regrow after a huge fire. and that doesn't include the animals displaced/killed in the disaster.

The MA of a lever is 4. If you have to lift the object up 20 cm,
how far will you have to pull down?
Answer:
jayfeather friend me
Explanation:
Answer: The mechanical advantage of a machine is 4. ... Mechanical advantage MA is the ratio of output (generated by the machine) force to input (applied to the machine) force. So MA = 4 means that for example if you apply 100 N then your machine will multiply that force and generate 400 N.
why don't birds get electrocuted when they land on an electric wire?
please help me out :-)
Answer:
Electricity flows by the movement of electrons through conductors. If a bird perches on a wire with two feet there is no motivation to go through the birds' body so electrons choose the path of least resistance and continue to flow along the wire.

What is the process that the tree uses to get its energy called?Does this process directly or indirectly affect the energy needs of animals such as the ostrich?
Photosynthesis is the process by which trees and all other flora (plants) get energy. And I think that it directly helps animals, such as ostriches, by providing food and O2 (oxygen). Without oxygen, humans and animals couldn't survive because there is too much CO2 (carbon dioxide) in the air (humans get this thing called carbon dioxide poisoning, which can kill you eventually). Also, without food, we would all starve to death.
Hope this helps! :)
Plants use a process called photosynthesis to transform solar energy into their own energy.
What is photosynthesis?Plants and other living things employ a process called photosynthesis to transform light energy into chemical energy that can then be released through cellular respiration to power the organism's activities.
Solar or radiant energy is converted into chemical energy during photosynthesis. The rate of photosynthesis has a direct impact on the productivity of agricultural crops.
It gives the atmosphere the oxygen that all living things need. It keeps the ecosystem's oxygen and carbon dioxide levels in check.
The process by which leaves take in carbon dioxide and water and use the power of the sun to transform them into chemical compounds like sugars that feed the tree is known as photosynthesis.
Thus, through the process of photosynthesis, tree uses to get its energy.

Which of these factors make hydrogen fuel cells a better option than burning fossil fuels?
Hydrogen fuel cells have a higher energy efficiency.
Hydrogen fuel cells create less pollution.
Burning fossil fuels relies on outdated devices and technology.
Hydrogen is the most abundant element in the universe.
Hydrogen fuel cells are more expensive than fossil fuels.
Hydrogen fuel cells have a higher energy efficiency.
Hydrogen fuel cells create less pollution
i got it right on the assignment
The use of hydrogen fuel cells is preferable to using fossil fuels since they are more environmentally friendly and have a higher energy efficiency. So, the correct options are A and B.
What is Hydrogen fuel cell?The use of hydrogen fuel cells is preferable to using fossil fuels since they are more environmentally friendly and have a higher energy efficiency.
Because they transform the chemical energy of hydrogen and oxygen into electricity with an efficiency of about 50–60% as opposed to the 30–40% of burning fossil fuels, hydrogen fuel cells are more energy efficient than burning fossil fuels. This increases efficiency and reduces waste by converting more of the fuel's stored energy into usable work.
Burning fossil fuels produces a variety of pollutants, including carbon dioxide, nitrogen oxides, sulphur dioxide, and water, whereas using hydrogen fuel cells only produces heat and water as byproducts.
Therefore, the correct options are A and B.

A shiver is caused by your muscles tightening and relaxing in rapid succession. This involuntary muscle movement is your body's natural response to getting colder and trying to warm up.
You shiver when your cold because your body kinda since's when your cold and you start shivering to make your body warm-up.

a candidate for which of the following?*
A. Cloning
B.gene therapy
C. DNA fingerprinting
D. Gel electrophoresis
A person with a genetic disease that codes for a specific protein could be a candidate for: B. gene therapy.
Genetics can be defined as the scientific study of hereditary and its components in an organism such as an animal, human, and plant.
Gene therapy can be defined as an experimental technique that involves the introduction of normal genetic materials into cells to produce a therapeutic effect that reconstructs or repair defective genetic materials, so as to treat a disease or cure genetic disorders.
Basically, gene therapy reconstructs or repair defective genetic materials found in body cells in an effort to treat or prevent a disease.
The three (3) main types of gene therapy are:
Gene inhibition therapy.Gene augmentation therapy.Killing of specific cells.In conclusion, an individual having a genetic disease that codes for a specific protein is most likely to be a candidate for gene therapy.

Diversity among members of a species is important because diversity
a
increases the chances of survival under changing conditions.
b
ensures high levels of competition.
c
increases the available ecosystem resources.
d
ensures the variety of reproductive methods for a species.
Diversity among members of a species is important because diversity increases the chances of survival under changing conditions.
If a disease spreads throughout a species, the species with genetic diversity will survive. If the species does not have genetic diversity, they will be wiped out by the disease.
