Which statement best describes the difference between a gene and an allele?

a.
a section of a chromosome that usually contains the code for a particular protein is an allele. a gene is one of two or more variations of an allele.

b.
a section of dna that usually contains the code for a specific protein that determines a specific trait is an allele, while a gene is a section of an allele.

c.
a section of dna that usually contains the code for a specific protein that determines a specific trait is a gene, while an allele is a section of a gene.

d.
a section of a chromosome that usually contains the code for a particular protein is a gene. an allele is one of two or more variations of a gene.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

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.
