Answer:

This is an English Language question and I need to choose the most appropriate option.

The answer is Option E

Explanation:

Option A is incorrect because 'each of which' is supposed to be followed by a singular verb 'is' and not 'are'. 'When' is used incorrectly here.

Option B is incorrect because 'which' is not introducing an meaningful non-defining clause in the statement. It is referring to the shark's jaws. The first two clauses are not connected to 'which'.

Option C is incorrect. 'Each one of which are ready' should be 'each one of which is ready'. It is also referring to the shark's jaw.

Option D is Incorrect. The use of a present continuous verb 'lying' is incorrect. The first clause also has not meaning.

Option E is correct.

The epithelial cells in the skin of an animal have 24 chromosomes. How many chromosomes are present in the gametes of this anima
mrs_skeptik [129]

Answer:

There will be 12 chromosomes

Explanation:

We have given that The epithelial cells in the skin of an animal have 24 chromosomes

We have to find the number of chromosomes present in the gametes of this animal

We know that number of chromosomes present in the gametes is given by

\frac{number\ of\ chromosmes\ present\ in\ skin}{2}

So number of chromosomes in gametes =\frac{24}{2}=12chromosomes

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 the cell membrane and mitochondrial membrane permeable to gases
Fofino [41]

Answer:

They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot. Small hydrophobic molecules and gases like oxygen and carbon dioxide cross membranes rapidly.
