what is the difference between circuli and annuli and what causes them to form? (referring to fish scales)

Circuli: Each growth ring is called a circulus (plural: circuli). Like a tree, the fish grows faster during the summer when the temperature is warmer and there is more food available, and the circuli are spaced farther apart. During the winter, growth slows down and the circuli are very close together.

Annuli: 1 : ring. 2 : a part, structure, or marking resembling a ring: such as. a : a line of cells around a fern sporangium that ruptures the sporangium by contracting. b : a growth ring (as on the scale of a fish) that is used in estimating age.

hello there,

igneous rock formed from below the surface would have more crystals because

answer: because magma cools more slowly than lava

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
