What is Pascal's principle?

Biology
1 answer:
Pani-rosa [81]3 years ago
7 0
“Pascal’s principle (also known as Pascal’s law) states that when a change in pressure is applied to an enclosed fluid, it is transmitted undiminished to all portions of the fluid and to the walls of its container. In an enclosed fluid, since atoms of the fluid are free to move about, they transmit pressure to all parts of the fluid and to the walls of the container. Any change in pressure is transmitted undiminished.”

vlada-n [284]

Answer:

1)

  • frequencies of light-colored mice  ≅ 0.74
  • frequencies of dark-colored mice ≅ 0.26

2)

  • frequencies of light-colored mice ≅ 0.13
  • frequencies of dark-colored mice ≅ 0.87

3)

  • q² = 0.74
  • p² = 0.02
  • 2pq = 0.24      

4)

  • q² = 0.13
  • p² = 0.4
  • 2pq = 0.46

5)

The dark-colored fur seems to have the greatest overall selective advantage

6)

Dark lava, that changed the color of the substrate, from light to dark.

7)

Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. All of the animals are inhabiting dark substrate, which means that this environmental condition is favoring the same phenotype.

8)

To see if the mice population is evolving, you need to take a sample of animals per year, through many years, and analyze if it is changing or not. If the population is evolving, you will notice a change in the allelic and genotypic frequencies over the years, favoring one genotype or the other. If the population is not evolving, the frequencies will keep equal through the years, it will not change.

Explanation:

Due to technical problems, you will find the complete explanation in the attached files.

Tropical rainforests have high species richness of trees. Provide the most reasonable explanation why animal species richness is
AfilCa [17]

Answer:

Here, is the question with the explanations to pick from to complete the question

Tropical rainforests have high species richness of trees. Which of the following statements provides the MOST reasonable explanation why animal species richness is also high in tropical rainforests?

Animals are unable to adapt to climate variability in higher latitudes.

Animals have had the same amount of time to evolve in rainforest areas as trees.

Animal diversification rates are higher than those of trees.

Animals have diversified into the vast number of niches provided by tree diversity

The last option is the most reasonable one

Our answer is:

Animals have diversified into the vast number of niches provided by tree

Explanation:

The reason is that a lot of species are highly specialized to occupy a particular niche. Where that favourable niche exists, the population of that species increases as its offspring colonize new areas.
