Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years (for the most massive) to trillions of years (for the less massive), considerably more than the age of the universe. ^
Small, relatively cold, low mass red dwarfs burn hydrogen slowly and will burn for hundreds of billions of years
Massive hot supergiants will live for just a few million years.
A mid-sized star like the Sun will remain on the main sequence for about 10 billion years. Hope tis helps!!
Answer:
In experimental animals, such as mice, rats, and dogs, DDT has shown to cause chronic effects on the nervous system, liver, kidneys, and immune system. It has also been found that humans, who were occupationally exposed to DDT, suffered chromosomal damage.
Explanation:
<span>The answer is a sexual reproduction. This is due to the formation
of gametes that enable the variation of the offspring of the parents. Firstly,
each gamete contributes half the genetic material (alleles)from either parent.
The dominant alleles will show in the phenotype of the c=ofspirng. Additionally,
during meiosis (the process that makes gametes), recombination of genetic
material can occur hence transferring unique combination of genes from that of
the parent. Therefore, there are many possible combinations of gametes that
gives the offspring variance from the parents</span>
Answer:B
Explanation: Pernicious anemia is a condition caused by too little vitamin B12 in the body. It is one form of vitamin B12 deficiency anemia. Vitamin B12 helps the body make healthy red blood cells and helps keep nerve cells healthy. ... The most common cause of pernicious anemia is the loss of stomach cells that make intrinsic factor.
