(B) Chlorinated hydrocarbons has demonstrated biological magnification. (C) Some low toxic chemicals transform high toxic by exploring sunlight or microbial metabolism.

(A) Allosteric regulation is the term used to describe any case in which a protein’s function at one site is affected by the binding of a regulatory molecule to a separate site.

複選題6. Mendel used the scientific approach to indentify two laws of inheritance, which comment about "Mendelian genetics" is NOT correct? (A) Mendelian genetics includes two laws as law of segregation and law of independent assortment. (B) The law of segregation states that genes have alternative forms, or alleles. (C) The law of independnet assortment states the pair of alleles for a given gene segregates into gametes independently of the pair of alleles for any other gene. (D) Traits are inherited in discrete units, and are not the results of blending. (E) In heterozygotes, the two alleles are different, and the expression of two different alleles makes phenotypic effects of the other.
