an alien species has two alleles for antennae shape: flat (f) and round (f). the flat (f) allele exhibits complete dominance, the round (f) allele is recessive. create a punnett square in your notes, and explain the probability of a baby alien having round antennae, if one of the parents had heterozygous dominant (ff) alleles, and one parent had homozygous recessive (ff) alleles.

What is the significance of the protein-lined pits? a. protein attracts other proteins needed for atp synthesis within the cell. b. protein-lined pits are able to transport one molecule at a time down the concentration gradient within the cell. c. the polarity of proteins allows other polar molecules to attach and be transported in the cell by transport channels. d. receptors within the pits allow ligands to fuse and be transported into the cell by endocytosis.
