Which solution of ethyl alcohol is more effective at inhibiting microbial growth: a 70% solution or a 100% solution? Why?

Biology
1 answer:
Triss [41]3 years ago
3 0

Answer:

70% solution is more effective

Explanation:

The 70% solution is more effective at inhibiting microbial growth than the 100% solution of the ethyl alcohol.

This is because the pure ethyl alcohol coagulates the protein that is in contact with it.

Also, pure alcohol will tend to evaporate faster than the 70% solution of the ethyl alcohol and it will not be that much effective.

In the Virtual Lab, what are two observations you made about how changes in an ecosystem can impact populations?
Papessa [141]

Answer:

  1. Changes in the environment can modify the amount of natural resources available for the populations to survive.
  2. Changes in the environment can separate a population and cause changes so intense that it prevents members of the population from establishing crossings.

Explanation:

As we know, changes in the environment can be caused by the manipulation of human beings or even by natural processes and phenomena of nature. What matters is that these changes always provide an environmental impact that can be beneficial or harmful, but will always affect populations.

Environmental impacts can cause changes in the environment that will modify the amount of environmental resources (food, water, habitat) needed for the populations to survive. The reduction of these environmental resources can cause an increase in the mortality rate of populations.

In addition, environmental changes can separate a population and cause an evolution in each separate part to the point of generating new species and not allowing members of each species to establish crosses.

Mars2501 [29]
I'm guessing sporophyte. I know mosses are nonvascular (they don't conduct their own food or water). They go through haploid and diploid phases. The haploid phase is most prominent in mosses.
Sorry if this isn't helpful.
