Hello! I’m learning about Biotechnology and am confused on this question, “Most plastics tend to persist in the environment because natural processes do not degrade them effectively. A scientist thinks that a new strain of bacteria can be developed to break apart plastics. To develop this strain of bacteria, the scientist proposes to subject a colony of bacteria to powerful mutagens.” Which statement best explains why the scientist’s proposal could be successful?: A: Mutagens that are properly chosen can produce any specific trait.

B:Mutagens act to preserve beneficial traits and reduce harmful traits within a population

C: A specific trait becomes more likely as the genetic diversity of a population increases.

D: A specific trait becomes more likely as genes from other species are added to a population.

the growth of the plants is affected by the heat of the light. what is the student doing?

the atomic number of magnesium is 12. its nucleus must contain 12 protons and no electrons. the atomic number of an atom is determined by the number of protons.

magnesium is an electrolyte injection commonly used to treat low magnesium levels in your blood. it is also used to prevent or control seizures in women with preeclampsia or eclampsia.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
