In the process of radioactive decay the unstable atom nuclei of the parent nucelus breaks down and split so as to release the daughter atoms or nuclei along with release of energy in the form of heat. Thus as the decay process proceeds the concentration of the parent atom decreases but the concentration of daughter atom increases.

What do these terms hydrophilic and hydrophobic mean and how do they relate to the structure of a cell membrane?.

Anarel [89]

Answer:

hydrophilic- attracts water

hydrophobic- repels water

Explanation:

The heads are point outwards as they attract water, and tails inwards as they repel water.

Hope this helps!
