What are the different ways in which nematodes can reproduce?

Embryogenesis, fragmentation and sexual reproduction

Explanation:

Nematodes can reproduce by embryogenesis, by fragmentation, or parthenogenesis and by sexual reproduction.

Embryogenesis:  when they are in larval state they can divide into several organisms.

Fragmentation, or parthenogenesis: a zygote is born without sperm intervention.

Sexual reproduction:  The male fertilizes the female and she lays hundreds of eggs.

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.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
