<span>Speciation is the formation of new species as a result of evolution these three stages are (separation, adaptation, and reproductive isolation.)</span>
The hemi
metabolism<span> indicates the three distinct
stages of the life cycle of some insects: the egg, nymph, and the adult stage,
or imago. It has no pupal stage just like the complete metamorphosis that
undergoes pupal stage before turning into adult. Insects that undergo hemi metabolous metamorphosis go through gradual changes; develop from
eggs into nymphs sometimes called larvae by some entomologists, that are
similar in shape to the adults. You can
distinguish the nymphs from the adults by looking for wings. Wing buds
or wing pads may be present in late stage nymphs, but they are fixed in place
against the body and are non-functional compared to the adults whose wings are
fully developed. </span>

Answer: a. endoderm-bone
Explanation: In the context of embryonic development, bone tissue may arise from several precursor cell populations, such as the neural crest (some facial bones), lateral mesoderm (bones of the limbs, among others), and paraxial mesoderm (vertebrae and part of the skull). There is no evidence to suggest that any of the bony structures is derived from the endoderm germ layer.
Answer:
D. Osmosis
Explanation: a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
