Well,a proto star is a new star.So whena new star forms the other star is no longer a proto star.

What temperature does a star start to fuse hydrogen?

The temperature at which hydrogen fuses is 10,000,000 degrees Kelvin. This is the minimum temperature the core of a proto star has to have to become a true star.


Is a proto oncogene the same as an oncogene?

No, a proto-oncogene and an oncogene are not the same. A proto-oncogene is a normal gene that plays a role in cell growth and division. When mutated or abnormally expressed, a proto-oncogene can become an oncogene, which promotes uncontrolled cell proliferation and contributes to cancer development. Thus, while all oncogenes originate from proto-oncogenes, not all proto-oncogenes become oncogenes.


What causes the heat to grow in a proto-star?

Compression. Whenever anything is compressed, it heats up. In a proto-star, clouds of hydrogen gas are compressed by gravitational attraction, and the compression heats the gas.


What is the dense center of a stellar nebula after it spins into a disk shape?

A "proto-star".


When proto-oncogenes mutate they may become?

They are called oncogenes.


What are proto-oncogenes and how do they differ from oncogenes?

Proto-oncogenes are normal genes that help regulate cell growth and division. When mutated or altered, they can become oncogenes, which promote uncontrolled cell growth and can lead to cancer. The main difference is that proto-oncogenes are normal genes that can become oncogenes through mutations.


Who named the protostar and why?

No one. It comes from the Greek - proto - meaning first. So first star - a protostar.


A mass of gas in space made hot by nuclear reactions?

A 'proplid', or a proto-stellar object, often called a proto-star, and some believe (as I do) that 'Herbig-Haro Objects', are newly formed stars. At any rate, a star is a mass of gas in space made hot by nuclear reactions.


What causes starts to form out of gas clouds?

Stars form from gas clouds when gravity causes the gas to condense and heat up, eventually reaching temperatures and pressures that trigger nuclear fusion. This fusion reaction releases energy, causing the proto-star to shine and become a fully-fledged star.


Is it true or false that only individuals with cancer have proto-oncogenes?

False. Proto-oncogenes are genes that can potentially become oncogenes, which are associated with cancer development. They are present in all individuals, not just those with cancer.


In the movie Tim refers to baby stars as protostars what can you infer about the prefix proto?

The prefix "proto-" typically means "first" or "primary," indicating that a protostar is an early stage in the formation of a star. This suggests that protostars are the initial phase in stellar development, where matter begins to clump together and heat up before eventually becoming a fully formed star. The use of "proto" highlights the evolutionary process that stars undergo from formation to maturity.


What is a protoplanetary disk?

A disk of gas ad dust that forms round a proto-star as the star coalesces at the center and from which planets accurate. The related links below give more information.
