En farmacología, el término mecanismo de acción (MOA) se refiere a la interacción bioquímica específica a través de la cual una sustancia farmacológica produce su efecto farmacológico. Un mecanismo de acción generalmente incluye la mención de los objetivos moleculares específicos a los que se une el fármaco, como una enzima o un receptor.
Answer:
Mitosis involves in cell division.
Explanation:
Mitosis may be defined as a process of cell division which results in the formation of two daughter cells each from a parent cell and each cell having having the same number of chromosomes and chromosomes of the same type as that of the parent nucleus.
The main difference between meiosis and mitosis of a nucleus cell is that it involves only one cell division. And so the cell goes by the steps of prophase, then metaphase, then anaphase and finally telophase. The specialized cells could not survive independently to each other, so they have to develop some complex system of communications like the circulatory system and the nervous system. In this way they can survive. If one of the system dies, entire organisms is more likely to follow.
Answer: A- Disruptive selection
Explanation: Disruptive selection increases genetic variation as the population begins to be more different when selection existing in nature chooses multiple phenotypes reaching the highest degree which each have particular benefits. However, they tend to make single-celled life form that has interposed characteristics to produce smaller offspring while allowing the organisms that have the highest degree of characteristics to produce more offspring.
I think the correct answer is A
