A monarch butterfly migrating
Explanation:
I think it is the butterfly because butterfly's fly right after they come out of the cocoon
In the 1800s, Darwin explains the origin of species. As species originate through adaptation by natural selection.
Answer: Species originate through adaptation by natural selection
<u>Explanation:
</u>
The Origin of species through natural selection is a pioneering scientific effort of the British naturalist Charles Darwin in England. Darwin's theory is that organisms are gradually evolving through what is called "natural selection"
It is a process in which organisms change due to hereditary changes in physical or behavioural traits. Changes that allow the body to better adapt to its surroundings, help it survive and have more offspring.
Crude oil is <u>refined to separate the chemicals used for gasoline, lubricants, plastics, and other products.</u>
<u />
- In a distillation tower, the crude oil is separated by boiling point after being heated by a furnace.
- The material is then transformed into finished goods like fuels like gasoline and diesel, as well as specialty items like asphalt and solvents, by using heat, pressure, or a catalyst.
- Ethane, liquid petroleum gas (LPG), and naphtha are the three main petrochemical feedstocks generated from crude oil.
- These are mostly employed in the creation of synthetic fibers, plastic polymers, and other petrochemical intermediates.
- With increased global income, demand for these products will only continue to rise.

Take two healthy potted plants. Keep them in a dark room for 2-3 days. Now place each plant in a separate glass. Get a cup containing potassium hydroxide by the side of the plants (the potassium hydroxide is used to absorb carbon dioxide). COver both plants with separate jars. Seal the jars so that the set-up-is-air-tight. Keep the plants in sunlight for two hours. Gently pluck a leaf from each plant. remove the chlorophyll from the leaves by boiling them in alcohol. Wash the leaves with water and then pour iodine solution over them.
We can conclude that the photosynthesis cannot be carried out without carbon dioxide. the leaf from the plant (which was the jar containing potassium hydroxide, which absorbed the carbon dioxide) turns blue black on iodine solution showing that starch is presented in this lead.
so this shows that carbon dioxide is necessary for the processs of photosynthesis to take place
