Gene maps represent the distribution of loci in a genome. a variety of techniques are used to construct gene maps because gene maps of organisms with large genomes are typically constructed by piecing together genome components. in particular, physical mapping approaches provide high resolution and accuracy by using molecular biology techniques. select the physical mapping methods. somatic cell hybridization linkage analysis dna sequencing in situ hybridization

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.

idk and i also need to know where are those bio brainy acts lol

reflection is the bouncing back of a propagating wave when it encounters a barrier; usually shows an image of the source of light wave

1) bounces back from an opaque material

2) bounces back from the boundary

3) seen in mirrors

refraction is the bending of a propagating wave having a shift of direction as it passes through different media; usually seen in lenses to magnify or lessen

1) passes through a prism

2) moves from one medium to another

3) seen in lenses
