Answer:
A. Toxicity
Explanation:
Toxicity is the ability of some chemical substance or medication to generate harmful effects on a living being, by coming into contact with it. Toxicology is the area of study that is dedicated to the toxicity of substances.
All substances have some degree of toxicity since any substance is capable of producing a toxic effect if a sufficient dose is administered. All substances are toxic; however, some are toxic to a greater degree compared to others.
Answer:
Almost nothing. We’d have plenty time to pack our bags and leave.
Explanation:
The random-walk process, radiative diffusion, causes the photon to take millions years to reach the surface of the Sun. So if fusion in the core of the Sun suddenly stopped, the surface would continue to shine for millions of years, and therefore, the luminosity would not decrease abruptly.
Answer:
Advances in DNA technology have allowed for treatments such as gene therapy in the medical field. Nowadays, there are tools like the CRIPSR-Cas9 - harnessed from bacteria's immune system- that can nip a ‘bad’ region of DNA, which is responsible for disease, and replace it with a proper functioning bit. This is how genetic disorders are going to be addressed in the near future in mainstream medical facilities.
Recombinant DNA technology is being used to create clones of transgenic organisms that produce products of significance in the medical fields. An example is incorporating the insulin gene in bacteria genome. These clones of modified bacteria colonies secrete insulin protein that is purified and injected in diabetic persons to lower their sugar level to normal.
