False. Respiration is providing oxygen for the cells and getting rid of the carbon dioxide, while digestion is transforming food into usable energy.
<span>Ions are another name for charged atoms. Some elements are electropositive, and some are electronegative. Electropositive elements such as metals like to give up electrons, thus taking on a positive charge. Electronegative elements such as chlorine attract electrons, so they become negative. When electropositive and electronegative atoms meet and exchange ions, they take on opposite charges. Because positive and negative charges attract, these charged atoms become attracted to one another. This attraction forms an ionic bond that keeps the ions together.</span>
I believe the answer is A
This is known as kin selection.
Behaviors which increase the reproductive success of genetic relatives increase the inclusive fitness of the individuals. If you have discussed Hamilton’s rule, recall that an allele will rise in frequency in the population over time if rb > c. Where r is the relatedness coefficient (to the relative benefitting from the behavior), b is the additional offspring that the relative has, and c is the personal offspring that are lost.
