Gene expression in eukaryotes can be regulated at various levels. Certain mutations in flies may cause them to develop an extra set of legs or wings. , which determine the formation and arrangement of body parts in multicellular organisms, control gene expression by regulation of .

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave

it marks things for degradation via the proteasome. it alters there celluar location.
