When homologous chromosomes exchange genes it is called

early in meiosis I the chromosomes can be seen clearly microscopically . as the nuclear envelope begins to break down the proteins assosiated with homologus chromosomes bring the pair close to each other .the tight pairing othr homoglogus chromosomes is called synapsis and an exchange of chromosomes segments between non sister homologus chromatids occours occours and is called crossing over

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.
