The answer to the above question is the Mendel's law of independent assortment. Mendel's law of independent assortment states that the alleles of two or more different genes get sorted independently into gametes of one another . That is the allele a gamete receives for one gene does not influence the allele received for another gene.
In multicellular organisms, several cells of one particular kind interconnect with each other and perform shared functions to form tissues (for example, muscle tissue, connective tissue, and nervous tissue), several tissues combine to form an organ (for example, stomach, heart, or brain), and several organs make up an organ system (such as the digestive system, circulatory system, or nervous system). Several systems functioning together form an organism (such as an elephant, for example).
The answer is letter b, persistence. This characteristic is often describe as a way of how long it will be useful, just like how long will the pesticides could be useful in killing the things that it is useful for in which is in consistent with the given statement above.
