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.

Answer: The sequence of events of avocado seed germination includes:
Water absorption --> enzyme activation --> radicle emerges --> lengthening of the hypocotyl --> growth of epicotyl and plumule development --> shrinking of the cotyledons.
Explanation:
Germination is defined as all the changes that occurs when a seed embryo resumes it's growth and development to become an independent seedling. Seeds usually germinate in two ways:
--> EPIGEAL germination: in this type of germination, the hypocotyl grows rapidly and elongates, carrying the cotyledon above the soil.The AVOCADO seed is a typical example of a dicotyledonous plant.
The sequence of events of avocado seed germination starts by imbibition which is the rapid in take or absorption of water by the seed through osmosis. Hydration of the embryo activates the enzymes in it which converts insoluble stored food materials into soluble forms. The testa splits and the radicle emerges first. It grows downwards as the primary root from which root hairs and branch roots arise( to form a tap root system). Next, the hypocotyl lengthens, pushes its way up through the soil carrying with it the cotyledons and the plumule. The cotyledons turn green on exposure to sunlight and start to photosynthesize. The epicotyl then grows and the plumule develops into a green shoot. By the time the first foliage leaves grow and begin to photosynthesize, the cotyledons shrink and drop off.
Answer:
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.
Explanation:
The classic example used to explain the concept of use and disuse is the elongated neck of the giraffe. According to Lamarck's theory, a given giraffe could, over a lifetime of straining to reach high branches, develop an elongated neck.Although the name "Lamarck" is now associated with a discredited view of evolution, the French biologist's notion that organisms inherit the traits acquired during their parents' lifetime had common sense on its side. ... According to Lamarck, organisms altered their behavior in response to environmental change.
<span>The skin and the liver. The skin is the largest organ in the body and interacts with most other organs in the body in some way, due to it's size and coverage, it is difficult to repair easily using skin cells. The liver is one of the most complex organs in the body and as the detoxifying organ in the body is complex to repair.</span>
