Plants obtain carbon by the uptake of atmospheric carbon dioxide.
Explanation:
There are a number of ways to produce hydrogen: Natural Gas Reforming/Gasification: Synthesis gas, a mixture of hydrogen, carbon monoxide, and a small amount of carbon dioxide, is created by reacting natural gas with high-temperature steam. The carbon monoxide is reacted with water to produce additional hydrogen.
As of 2020, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming of natural gas, partial oxidation of methane, and coal gasification. Other methods of hydrogen production include biomass gasification and electrolysis of water.
Answer:
The field of evolutionary medicine uses evolutionary principles to understand changes in human anatomy and physiology that have occurred over time in response to environmental changes. Through this evolutionary-based approach, we can understand disease as a consequence of anatomical and physiological “trade-offs” that develop to facilitate survival and reproduction. We demonstrate how diachronic study of human anatomy and physiology is fundamental for an increased understanding of human health and disease.
ANSWER: Carbon Dioxide
-Coal actually burns more than one gas, but out of all the choices, Carbon Dioxide is the only one that's true.
Lol, Hope this Helps!!
The mixed number for the given picture is 1 1/4, the correct option is A.
<h3>What are mixed numbers?</h3>
A mixed number is one that manages to combine a whole number and an appropriate fraction.
To transform mixed numbers to improper fractions, follow these three steps: Multiply the numerator by the whole number.
- Step 1 is to the numerator, add the answer from.
- Step 2 is adding the numerator to the product got from step 1.
- Step 3 is writing the improper fraction with the sum got from step 2 in the numerator/denominator form.
In the given picture, there is one box completely filled and one forth portion in second block is filled, so it is representing mixed number i.e., 1 1/4.
Thus, the correct option is A.
