Answer:
Nebula --> Protostar --> Supergiant --> Supernova --> neutron star
Explanation:
A high mass star starts as a big cloud of dust and gases. This cloud is called a nebula. When these clouds pick up some momentum, it condenses into a protostar.
The protostar will continue to condense because of its increasing gravity. The hydrogen atoms will start to collide and the pressure and temperature will trigger nuclear fusion. This is when the start will enter its main sequence where the outward force of nuclear fusion is balanced with its inward force. It will remain at this state until it runs out of hydrogen atoms.
When hydrogen stats to run out, the gravitational force will be greater than the force of nuclear fusion causing the core to shrink. Nuclear fusion then will start to occur outside the core and the star then expands into a Super giant.
The expansion of the star enables the star to create heavier elements like helium which then undergoes fusion itself and becomes a source of fuel for the star. When helium slowly depletes, it pulled into the core by gravity and all that is surrounding the core will explode , making it a super nova which marks the end of a star.
Two things can result from a supernova, a neutron star or a black hole. For bigger stars, the result would be a black hole. If the mass of the star was at least three times greater than our sun, then it will implode and become a black hole. If it is less, then the core would form a neutron star.
Answer:
After this, rRNA creates bonds between <u>amino acids</u> to make <u>proteins.</u>
<u>Some important points to know:</u>
rRNA (Ribosomal RNA) is used in the synthesis of proteins.
Amino acids are the building blocks of proteins which means that proteins are made up of amino acids.
When amino acids are joined together, they form proteins.
The bond between two or more amino acids when bonded is called "peptide bond".
Hope this helped!

Inorganic elements that are extracted from the soil by plants and passed up the food chain are known a Minerals.
- Minerals are inorganic compounds that make up the majority of the soil solution; among those needed by plants for structure and control are nitrogen (N) and potassium (K).
- Plants nevertheless need inorganic salts, which they take up from the soil around their roots. These salts contain the elements phosphorus (in the form of phosphate), chlorine (as the chloride ion), potassium, sulphur, calcium, magnesium, iron, manganese, boron, copper, and zinc.
- Group of creatures arranged from producers to consumers in the food chain, as well as prey, predators, scavengers, and decomposers. food chain. noun. each connected food chain within an ecosystem. Likewise known as a feeding cycle.

All three scientists would most effectively demonstrate their concepts by using models.
Models are often used in science to provide a simplified visual representation of a certain phenomenon, making it easier to observe, understand and predict the possible future outcomes or effects of the demonstrated phenomena.
To analyze why he inoculates the boy, you need to analyze what happens with vaccines.
A vaccine is a solution with a decreased or dead virus. Our body recognizes that virus and creates anti-viruses. If you get the infection, your body already knows how to kill that antigen.
Edward Jenner saw that dairymaid gets affected by cow's version of smallpox, only on their hands, and then they don't suffer human smallpox.
He wants to prove that, without knowing what we call immunization now, and inoculate the boy.
