Answer:

D. Nuclear fusion begins under high pressure.

Explanation:

A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.

Some of the examples of stars are;

  • Canopus.
  • Sun (closest to the Earth)
  • Betelgeuse.
  • Antares.
  • Vega.

Stars are typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He). The chronological order in which the formation of a star occur are;

1. Gravity pulls gas and dust together to form dense cores.

2. A protostar forms as mass increases.

3. Nuclear fusion begins under high pressure.

Hence, the final event that occurs when a star is forming is that nuclear fusion begins under high pressure.

Scientists’ understanding of the role and function of DNA has built up over time. How did the findings from Hershey and Chase’s
mr_godi [17]

Answer:

Hershey & Chase concluded. after the experiment that the genetic material that is passed from virus to the bacteria is not the protein coat but DNA. It proves the DNA is the genetic material and not the protein.

After labelling the Phage DNA and protein, Hershey and Chase performed a series of experiments like infection, blending and centrifugation. Hershey and Chase gave full evidence of the DNA being a genetic material by their experiments. To perform the experiment, Hershey and Chase have taken T-2 bacteriophage (invaders of E.coli bacteria).

As you learned, thalidomide is a teratogen meaning that causes birth defects when taken by pregnancy women. Another teratogenic
konstantin123 [22]

Presence of a teratogen in the body of mother during pregnancy is responsible for mal growth of child or incomplete growth which may lead to abortion, still birth or even a defective child.

A teratogen is a substance that is known to cause <em>defects</em> in growth of child during the intrauterine growth period. Thalidomide was used as a morning sickness drug which relieved the vomiting nature of the would be mother. But the presence of thalidomide was responsible for less growth of limbs of the child. Alcohol in intrauterine life may cause Fetal Alcoholic Syndrome which damages the fetus' sense organs and neural cord.

The presence of a teratogen during the 1st trimester is more serious than in last trimester because the main formation of different organs and systems take place in the 1st trimester and maturity takes place in third trimester.
