Answer:

Coal.

Explanation:

Steam power plant has the lowest efficiency in electricity production which can only be run with the use of fossil fuels such as coal. The efficiency of this power plant is the lowest because large amount of coal is converted into smoke and other gases and very less amount of coal into heat energy. This coal is used to produce heat energy which can be used in the heating of water to produce steam. This steam is used to move turbines which turn mechanical energy into electric energy.

NARA [144]

Answer:

Amino acid sequence is directly related to the differences in the DNA of the species.

Explanation:

Above situation is related to the evolutionary research in which scientists are in search of common characteristics between species and from those species they will examine the amino acid sequence of proteins because amino acids sequence is directly related to the sequence of DNA and DNA is the main thing among all other variables by which differences in species can be identified effectively.

small group of 100 people decide to isolate themselves from the world and move to a small and remote deserted island. Out of thi
irina [24]

Answer:

Frequency of p = 0.684

Frequency of p = 0.316

Number of individuals with homozygous dominant (AA) = 47

Number of individuals with heterozygous (Aa)= 43

Number of individuals with homozygous recessive (aa) = 10

Explanation:

Out of 100 people, 10 have albino skin (aa)

So, the frequency of homozygous recessive individuals (q^{2}) is \frac{10}{100} = 0.1

Now, q will be

= \sqrt{q^{2} } = \sqrt{0.1} \\= 0.316

As per Hardy Weinberg's equation -

p + q = 1

Substituting the value of q in above equation, we get -

p + 0.316 = 1p = 1 -0.316\\p = 0.684

Now the frequency of homozygous dominant (AA) will be

p^{2} = 0.684^{2} \\= 0.467

Hence, out of 100 people 0.467 * 100 = 46.7 or 47 people are homozygous dominant (AA)

Like wise out of 100 people 0.1 * 100 = 10 people are homozygous recessive (aa)

As per As per Hardy Weinberg's equation-

p^{2} + q^{2} + 2pq = 1\\

Substituting the values in above equation, we get -

0.467 + 0.316 + 2pq = 1\\2pq = 1 -( 0.467+ 0.1)\\2pq = 0.433

So, out of 100 people 0.433 * 100 = 43.3 or 43 people are heterozygous (Aa)
