A fatty acid contains primarily carbon and hydrogen atoms, and its hydrocarbon tail is very hydrophobic. What kind of interactio
balu736 [363]

Answer:

Hydrophobic interaction.

Explanation:

On the basis of the polarity and the dissolution of water, the molecules can be classified into the hydrophilic and hydrophobic molecules. The hydrophobic molecules can easily dissolve in the non polar solvents.

The hydrophobic interaction is important that exist between the non polar molecules. The hydrophobic interaction plays an important role in the biological system as the lipids of the cell membrane are assisted together with the hydrophobic interaction. The hydrocarbon tail is non polar molecules that contains hydrophobic interaction within it.

Thus, the correct answer is hydrophobic interaction.

A population of 100 tigers has 30 with horizontal stripes. Using pedigrees, you ascertain that horizontal striping is caused by
bixtya [17]

Assuming that this population is in Hardy-Weinberg equilibrium, we can sayt that  <em>the</em><em> probability</em><em> that, given enough time, all tigers in the population will have horizontal stripes is</em><em> 30% = 0.3.</em>

--------------------------

<u>Available data:</u>

  • Population size, N = 100 tigers
  • Number of Tigers with horizontal stripes = 30
  • Horizontal stripes is caused by an autosomal recessive mutation.

We need to know the probability that all tigers in the population will have horizontal stripes, which is the recessive phenotype.

We assume that the population is in Hardy-Weinberg equilibrium, so there should be no evolution.

Since the population is in H-W equilibrium, the allelic, genotypic and phenotypic frequencies will remain the same generation after generation.

Now, we will calculate the allelic and genotypic frequencies of horizontal striped individuals in the population.

There are 100 individuals, and only 30 have horizontal stripes.

So, the phenotypic frequency, F(HS) is 30/100 = 0.3 = 30%

Since this is a recessive phenotype, this value equals the genotypic frequency, F(hh) = 30%

Finally, we can get the allelic frequency by taking the square root of this value.

F(hh) = q² = 0.3

f(h) = q = √0.3 = 0.55 = 55%

According to these calcs, the probability for the fixation of the recessive allele is 55%, and the probability that all individuals express the recessive horizontal stripes phenotype is 30%.

Are climate change models accurate enough for costal city infrastructure planning?
ankoles [38]

Answer:

Yes

Explanation:

In the past climate change models were not accurate as they mostly understated the problems which resulted in more damages caused due to inaccurate preparations. However due to new technological innovations, there has been availability and improvement in the tools such as satellites.

This has led to an increase in the accuracy of the climate change models and subsequent planning of costal city infrastructures.
