A. Produce gametes and produce hormones
The two major functions of the gonads in the adult are steroid hormone production and gametogenesis.
The gonads, the primary reproductive organs, are the testes in the male and the ovaries in the female. These organs are responsible for producing the sperm and ova, but they also secrete hormones and are considered to be endocrine glands.
Gonads are male sex glands. They produce sex hormones and sex cells. In the male, the interstitial cells of the testes produce and secrete the male sex hormone testosterone. This controls the development and function of the male secondary sex organs, as well as the secondary sexual characteristics.

The structure of plasma membrane makes it selectively permeable allowing it to regulate the passage of substances into and out of the cell. Small nonpolar molecules can easily across the phospholipid bilayer of plasma membrane because it is hydrophobic. Polar molecules and ion cannot easily across the hydrophobic portion of plasma membrane because it is hydrophilic. Polar molecules and ions usually across the plasma membrane with the help of transport proteins.

Answer:
The answer is the heat resistance of DNA and the "transformation" process.
Explanation:
The experiment showed that after inactivating the cell with heat, the DNA was intact, and through a transformation process, or what we know now as Horizontal transference of genes, the R bacteria could adapt the genetic features that allowed the S bacteria to kill the mouse.
