The opening and closing of ligan-gated ion channels
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.
Answer:
the fill in the blank can be filled with new muscle tissue, digestive enzymes, hormones, and bone.
Answer:
Diversifying or disruptive selection increases genetic variance when natural selection selects for two or more extreme phenotypes that each have specific advantages.
I would say A. Either tall or short
When Mendel crossed purebred short plants with purebred tall plants, all of the offspring were TALL
The pure-bred tall plant dominated the short
