These piers are usually 16âx16â and are designed to support the floor, wall and roof loads. In between the piers are one brick thick walls called âcurtain walls.â It is not meant to support the house, but is just there to close in the basement or crawlspace, keep it dry and keep out the critters.
Gametogenesis is a biological process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid gametes.nimals produce gametes directly through meiosis in organs called gonads (testicle in males and ovary in females). Males and females of a species that reproduces sexually have different forms of gametogenesis. 1  spermatogenesis (male). 2  oogenesis (female).
Gametogenesis: The development and production of the male and female germ cells required to form a new individual. The male and female germ cells are called gametes.The gametes in human males are produced by the testes, two globe-shaped reproductive organs just below the penis.he reproductive organs in both males and females (testes and ovaries, respectively) begin gametogenesis with a primitive germ cell. A primitive germ cell is a seed cell. Like a seed planted in a garden, a primitive germ cell initiates the process that eventually results in a new being.
