In garden peas, the allele for tall plants (t) is dominant over the allele for dwarf plants (t). a true-breeding tall plant is bred with a true-breeding dwarf plant to produce heterozygous tall plants. the f1 heterozygotes then self-fertilize to yield f2 offspring. complete the punnett square for this monohybrid cross using the f1 gametes with the appropriate genotype and placing the correct f2 genotype/phenotype combination in the punnett square.

Every compound can be represented by a chemical formula. a chemical formula is the set of symbols showing the elements that make up a compound and their proportions. water’s chemical formula is h 2 2 o. that means a molecule of water contains two atoms of hydrogen and one atom of oxygen chemically bonded. a molecule is a group of two or more atoms bonded together. molecules can range in size from two to thousands of atoms. a molecule of a compound is the smallest unit of that compound. every molecule of water has all the physical and chemical properties of water. that’s because every molecule of water is made of the same elements in the same proportions: two hydrogen atoms and one oxygen! which of the following is a true statement? a every molecule of the same compound will have different properties. b every molecule of a compound has the same proportion of elements. c molecules can be physically separated into smaller units of a compound. d molecules cannot be represented by chemical formulae.
