Biology paper for senior three
1. in the following statement of the basic features of the organism, what is correct is that
A. stress enables creatures to adapt to certain circumstances; B. succession only shows genetic characteristics
C. independent replication is the process of viral proliferation, and D. assimilation results in digestion, absorption, and nutrition
[analysis]: biological stress has to adapt to the environment, so choose A, only the characteristics and genetic variation of the continuation of B race; virus replication cannot do without the host cell; D assimilation is the result of the digestion and absorption of nutrients and the nutrients into their own material. So choose A.
2. the sugar of lichens, sugar cane, mycoplasma, and amoeba is
A. B. C. D. ribose glycogen starch cellulose
[ribose]: ribose is necessary for RNA. The biosynthetic proteins must be transcribed and translated without RNA (mRNA, translocation, RNA, and ribosomal RNA), so select D.
3. by measuring a compound containing C, H, O, N, and P elements, one of the most probable functions of the compound is that
A. is specifically bound to antigen and B. carries amino acids into the ribosome
C. is used in genetic engineering to obtain sticky ends, and D. can be connected with anticancer drugs to make biological missiles
[analysis] the composition elements of nucleic acids contain C, H, O, N, P, while the protein components contain C, H, O, N, S, so the compound is nucleic acid, and only B transport RNA meets the requirements. ACD is the function of protein. So choose B.
The 4. is a substance widely exists in plant cells of a compound composed of 104 amino acids, plays an important role in the process of generating ATP, then place the place and synthesis of this material are mainly play a physiological role
A. Golgi and chloroplast B. ribosomes and nuclei
C. ribosomes and mitochondria, D. nuclei and mitochondria
