Answer:
This a source which energy can be extracted, used and still be transformed maybe directly or into another energy form.
Explanation:
Different energy sources can be renewable and non renewable. Fossils such as coal and crude oil are the most common sources of energy in industries and homes. Here, we can cut down fuel requirements using burners, furnaces and engines that burn the fuel more efficiently.
Alternative sources of energy include hydroelectric power, nuclear energy, wind generators and solar panels. Wood, alcohol, could also be used as alternative sources of energy. Ad these are products of photosynthesis, they are renewable.
Well lack of competition LEDS TO> lots of variation which LEDS TOO> speciation
I hope that helps
Answer:
A) Decreases;increase
Explanation:
When there are high levels of carbon dioxide in the respiratory system, the blood pH level decreases, causing respiratory rate to increase.
This condition is acidosis because not enough CO2 escapes lungs hence CO2 accumulates and decreases pH of blood, making it more acidic. As blood pH drops (becomes more acidic), the parts of the brain that regulate breathing are stimulated to produce faster and deeper breathing to increase the amount of carbon dioxide exhaled to bring our body to the ideal pH.
Since Australia is located in the Pacific ocean, extremes of weather and climate happen throughout a season. El Niño is traditionally defined as a dry climate with reduced rainfall; in this happens to be more extreme in Australia because of its location. La Niña on the other hand is traditionally defined as a wet or cool climate with lots of rainfall; and this is indifferent as La Niña in Australia tend to be more extreme too.
Answer: One sign of physical change is melting, freezing.
