3. (4 pts). A diploid somatic cell of a hypothetical eukaryote contains two pairs of homologs in its nucleus (2N = 4). One pair of homologs is metacentric and the other pair is submetacentric. The metacentric pair is heterozygous at two gene loci and each locus is on a different arm. At one locus, the alleles are identified by the letters “A” and “a”. At the other locus, the alleles are identified by the letters “B” and “b”. The upper...

18. (2 pts.) The equations for organic reactions usually focus on the desired transformation from reactant to product, other possible products such as byproducts and/or side products are often not included, even though it is understood that these are also formed in almost every organic reaction. Shown below is a complete equation for the ester synthesis reaction for the case of 2-pentanol, that includes all possible products, including the desired product, side product(s) and in this case some byproducts...

Discussion Questions The structures of acetanilide and malonic acid are provided below 1. For each structure, draw circles around the polar and nonpolar regions of the molecule, and label each circled regiorn with the type of intermolecular attractive force it can use to interact with other molecules. Acetanilide Malonic Acid но CH2 OH 2. Now-thoroughly explain (on the basis of polarity/nonpolarity and intermolecular attractive forces) how the acetanilide was separated from the malonic acid by recrystallization from water. And explain...
A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...
