Answer:
a. minimum voltage that must be supplied for a redox reaction to occur
c. always equal to Eanode - Ecathode
Explanation:
In an electrolytic cell; The electromotive force(the maximum standard potential difference) of the cell formed by the system is defined as the standard electrode potential of the right handed electrode minus the standard electrode potential of the left hand electrode. (i.e )
As we all known that the process by which chemical energy is being converted to electrical energy is called the Electrochemical cell. It consists of two half cells , an oxidation half cell reaction and a reduction half-cell reaction.The overall redox reaction results in a flow of electrons in an electric current which is produced by a minimum voltage.
Therefore, option a and c are both correct.
Answer:
Yeast cell is different from an onion skin cell in that Yeast can reproduce by budding while onion skin cells do not reproduce by budding.
Explanation:
- Reproduction is one of the characteristics of living organisms. All living organisms undertake reproduction to give rise to new organisms.
- There are two major types of reproduction namely asexual and sexual reproduction.
- Asexual reproduction is a form of reproduction that does not involve the fusion of gametes among organisms. Examples of asexual reproduction are budding in yeast and vegetative propagation in plants such as onions.
- Sexual reproduction, on the other hand, involves the fusion of gametes from male and female organisms which results in the formation of an embryo that develops to the fetus which becomes the offspring.
- Therefore, we could say that yeast cells reproduce asexually through budding while onions reproduce asexually through vegetative propagation.
Answer:
Isotopes are atoms with the same number of protons, but different numbers of neutrons.
Explanation:
Ex.
Ne 20/10
Ne 21/10
Ne 22/10
*the number of protons in an atom must stay the same or the element itself will change drastically
In water masses caused by temperature and salinity variations, gravity, and events such as earthquakes. Currents are cohesive streams of seawater that circulate through the ocean
