Genetic equilibrium is the state in which allele frequencies do<br> not change in a<br> Check it
Vikentia [17]

Answer:

Genetic equilibrium is the state in which allele frequencies do

not change in a generation over generation.

Explanation:

Genetic equilibrium can be described as a situation which arises when a certain allele or genotype remains constant for a species generation over generations. Genetic equilibrium can be maintained if no external factors like mutations affect the population of the species. The phenomenon of natural selection and evolution need to be stopped if a genetic equilibrium is to be maintained. Hardy-Weinberg theorem is the mathematical depiction of genetic equilibrium.

What is the energy of a TV wave that NBC broadcasts, if it has a wavelength of 32 meters?
serg [7]

Answer:

Explanation:

E = hc/λ

h = planck's constant = 6.66 x 10 ^ -34

c = speed of light = 2.98 *10^8 m/s

E = (6.66 x 10 ^ -34 )(2.98 *10^8)/32

  = 19.85 * 10 ^-26

   =0.62 x 10^-26

   = 6.2 x 10^-27 J

The Statue of Liberty, though known for its green color, was originally covered in a layer of copper. After a redox (reduction-oxidation reaction) the color changed due to a chemical change.

2. Gas Production

3. Light Produced

Light sticks work as the result of a chemical reaction between hydrogen peroxide and phenol oxalate ester.

4. Temperature Changes

What might you expect for the value of S∘ (entropy) for butane, C4H10?
Norma-Jean [14]

Answer:

340 J·K⁻¹mol⁻¹  

Explanation:

I looks like the standard entropy increases approximately linearly with the number of C atoms.

I plotted S° vs the number of C atoms and got the graph shown below.

It appears that S° for four carbon atoms should be about 340 J·K⁻¹mol⁻¹.·
