Explanation:
Answer:
Water can hydrogen bond.
Explanation:
Liquids become gases once they are heated to a certain temperature. Heat is a form of energy. This change occurs when the intermolecular forces between the liquid molecules are energized enough to break. This breakage is necessary because gaseous molecules exist individually and do not interact with one another. That being said, it takes more heat to boil water because its intermolecular forces are stronger than methanes.
Intermolecular forces (IMF) are a result of partial charges on the molecular atoms that cause temporary bonds to form between molecules.
Methane is a nonpolar molecule, meaning each atom can only have slight partial charges. The strongest IMF methane participates in are London Dispersion Forces.
Water, however, is a polar molecule, with the hydrogens having strong partial positive charges and the oxygens having strong partial negative charges. This allows water to participate in a very strong IMF called hydrogen bonding. Again, because these partial charges are so strong, the water molecules can form stronger IMFs.
<u>*When molecules have stronger IMFs, they require more energy(heat) to overcome them.*</u>
interphase, telophase, and cytokinesis
Answer:
The correct genotype would be-
mom: homozygous recessive, father: heterozygous or homozygous dominant, and son : 50%(if father heterozygous dominant) to 100%( if father is homozygous dominant) chances of being hetrozygous dominant.
Explanation:
Listing the genes in the way that they indicates the real combination of alleles is the genotype of individual.
Ability to roll your tongue is a dominant character which has a dominant and a recessive gene. Assume that the dominant allele ‘R’ is for the ability to rolling tongue and the recessive allele ‘r’ for unable to rolling our tongue. As we know mother can not roll her toungue she must have homozygous recessive alleles that means she has two copy of recessive allele. The father could posess any combination of these alleles: RR (homozygous dominant), or Rr(heterozygous dominant).
Thus, the correct genotype would be
mom: homozygous recessive, father: heterozygous or homozygous dominant, and son : 50%(if father heterozygous dominant) to 100%( if father is homozygous dominant) chances of being hetrozygous dominant.
