In 1929 the American astronomer Edwin Hubble discovered that the distances to far-away galaxies were proportional to their redshifts. Redshift occurs when a light source moves away from its observer: the light's apparent wavelength is stretched via the Doppler effect towards the red part of the spectrum. Hubble’s observation implied that distant galaxies were moving away from us, as the furthest galaxies had the fastest apparent velocities. If galaxies are moving away from us, reasoned Hubble, then at some time in the past, they must have been clustered close together.

HELP PLEASE! Why is it very unlikely for a frameshift mutation to be a silent mutation?
ehidna [41]

Answer:

Explanation: A frameshift mutation completely changes the genetic code from the point of the mutation, so the protein made as a result of the mutation would have the incorrect structure and would not function as it should.

Concentration cell based on the Ni2 -Ni cell reaction.
Alex73 [517]

Answer:

Explanation:

The missing diagram contained in this question is first attached in the image below.

The objective of this question is to determine how ions migrate when the cells are operating by assuming the solutions are composed of Ni(NO3)2.

From the information provided:

In this instance, the ions tend to move first from cathode to anode in terms of raising the concentration of Ni(2+) at the anode, resulting in the development of a dead cell. The initial concentration of [Ni(2+)] in the anode solution is 1.00 × 10⁻³ M, which gradually increases to 0.5 M, during which both the cathode and the anode possess the same concentration at the same point.

This causes Q(equilibrium constant) to equal  1 as well as log(Q) to equal 0, indicating that the cell is dead.

As a result, the cell will cease to operate, and nothing will migrate from the left to the right side.
