An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. Kinetic energy is a scalar quantity; it does not have a direction. Also energy that a body possesses by virtue of being in motion.
Equation:

KE = 0.5 • m • v2

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)

Explain the importance of the nitrogen base and their role in preserving the code

sukhopar [10]

Ans.

Genetic codes provide information for the protein synthesis as each code specifically codes a particular amino acid that gets joined in polypeptide chain during the process of translation.

Each genetic code is three letter code, made up of three nitrogenous bases. There are four different bases in DNA or RNA that make sixty four codes with different combinations, out of which sixty one code for amino acids and three act as stop codons.

Thus, nitrogenous bases are important in preserving the genetic codes.

Consider the following cross: Parent 1: YyTt Parent 2: YyTt Using the rules of probability, determine the probability that the o

taurus [48]

The offspring WILL NOT get the YyTT because if this is in the form of say dominant genes, there are no T recessives.
Hope this Helps!!
