All of the following statements about homeotic genes are correct except group of answer choices homeotic genes were first identified in invertebrates, but their homologues were found in almost all organisms. all homeotic genes contain consensus sequence that result in specific dna-binding motif. in vertebrates, homeotic genes are organized into two distinct clusters. all homeotic genes encode transcription factors that direct further gene expression. homeotic genes exhibit a relationship between their order on the chromosome and the timing of their expression.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

explanation:

idk

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.
