Answer 1: Difference b/w wet and dry earwax genes is due to switch of a single DNA unit i.e. single nucleotide polymorphism.
Answer 2: Earwax is important in many ways mainly it is a biological flypaper as it prevents dust and insects from entering the ear.
Answer 3: Genetics have proved that for those who sweat a lot and have armpit odor have wet earwax.
Answer 4: The wet type earwax is dominant one with honey brown or dark brown color while dry one is recessive.
Answer 5: As wet earwax is dominant trait, according to the given scenario the genotype of parent with wet earwax will be "WW" which when crossed with dry earwax parent will have all the offsprings with wet earwax.
The amino acids are the building blocks of the proteins.
Explanation:
The amino acids are the organic molecules made up of a carboxylic group, an amino group and a carbon side chain. The proteins are macromolecules, made up of amino acids. Many amino acids combine to form a protein. The structure of the protein depends on the sequence of the amino acids present in the structure of protein. A different protein has a different sequence of amino acids.
Answer:
DNA is the blueprint of life because it is what tells our bodies what to make, how to make us , and what to give us.
Answer: Lipid molecules.
Explanation: Biological membranes are bilayer of phospholipids that control the entrance and exit of molecules in the cells. The major components of phospholipids are the fatty acids. Phospholipids have two components: the fatty acyl chains and the phosphate group. The fatty acyl chains of the phospholipids molecules face each other at the core of the bilayer, forming a fluid hydrophobic interior while the phosphate (polar head) groups face outward. Proteins are embedded in this bilayer held by hydrophobic interactions between the membrane lipids and hydrophobic domains in the proteins. Both proteins and lipids move laterally in the plane of the bilayer but movement from one face of the bilayer to another is restricted.
