<span>Gonads is a reproductive gland which leads to production of sex cells, kown as gametes. A gamete contains half of the genetic information of an offspring. Human gamates: sperm and ovum, fuse and lead to formation of zygote, which develops into an offspring.</span>
Answer:
Option (A).
Explanation:
Artificial passive immunity can be acquired by injecting readymade antibodies. The antibodies are not produced by the recipient cells of the organism.
The injection of gamma globulin is artificially acquired passive immunity as these antibodies are injected directly into the body of the recipient. This immunity is given to provide short term immunization to an individual organism.
Thus, the correct answer is option A.
One can isolate the gene for human insulin from human cells, and put that gene into a plasmid (small circular DNA molecule). That plasmid is then put into bacterial cells, and the bacteria produce insulin as coded for by the human gene. It is necessary to include the neccessary bacterial promoters etc, so that the cell can actually read the DNA message, but because the genetic code and the language of codon/anticodon/mRNA/tRNA etc. is universal, a gene in one organism is readable by another organism.
True.
Hope this helps (:
