Answer:

Nucleic Acids:

- Uracil

- Adenine

- Guanine

- Cytosine

Explanation:

Since we only have one strand shown, I'm going to assume it is RNA. Both DNA and RNA have nucleic acids, but RNA has 1 different nucleic acid; it replaces Thymine with Uracil. So the 4 nucleic acids are uracil, adenine, guanine, and cytosine.

If the picture shown is a cross-section of DNA, then our 4 nucleic acids are adenine, thymine, guanine, and cytosine.

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%.

ad-work [718]

Answer:

Simple clothing, living in farming communities and using horse- driven vehicles best describes Amish culture.

Explanation:

The simple clothing concept of Amish culture shows their modesty. The women wear long and simple dresses that goes all the way down to their knees and they also cover their hair. They believe wearing simple dress is a way of keeping their hearts pure.

Amish people use buggy or horse driven vehicles and not cars because they believe that the innovation in technology has the potential to bring assimilation into the surrounding society.

They mostly live in farming communities which are located in Indiana, Pennsylvania, Ohio, Central American and even in Canada.
