Which statement correctly describes the structure of a centriole? a) 3 groups of 9 microtubules b) 4 groups of 6 microtubules c) 6 groups of 4 microtubules d) 9 groups of 3 microtubules

The right answer is D) 9 groups of 3 microtubules

Centrioles are the constituents of a so-called centrosome structure: every animal cell has a centrosome, which is made of two centrioles and which together form a functional unit. A centriole consists of nine triplets inclined microtubules, surrounded by a number of proteins.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.
