Task1:

What is the molecular mass of a gene, if one strand of DNA molecule encodes the polypeptide molecule with molecular mass is 4500g/mol? Molecular mass of one amino acid is 100g/mol, molecular mass of one nucleotide is 345g/mol.

Tas 2. Define and characterize all stages of transcription.

b. read the phase at the intersection of any given temperature and pressure.

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.
