Answer:
The correct answer is - disrupting microtubule assembly and proper formation of the mitotic spindle and the kinetochore.
Explanation:
Vinblastine is known for treating cancer cells by sending them to apoptosis. It interferes with the synthesis of microtubules. It binds to the microtubular proteins of the mitotic spindle that causes disrupting microtubule assembly.
It also prevents from proper formation of the mitotic spindle and the kinetochore which is essential to separating chromosomes during anaphase. They arrest mitosis and cause cell death.
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.
Survival of the Fittest (Natural Selection):
When bacteria are initially exposed to an antibiotic, those most susceptible to the antibiotic will die quickly, leaving any surviving bacteria to pass on their resistant features to succeeding generations.
Answer:
London smog results from a high concentration of sulfur oxides in the air and is caused by the use of sulfur-bearing fossil fuels, particularly coal. This type of smog is aggravated by dampness and a high concentration of delayed particulate matter in the air.
Explanation:
So, the answer would be B or D.
But, it is most likely B due to dampness.
If you’re talking about too many people I’m guessing the limitation factors would be lack of resources and that would include lack of food and space.
You would die because the radiation levels would disrupt brain waves causing heart failure, stroke, ect.
