Answer:
located... on the plasma membrane
is considered... inactive
the messenger is considered... to be active
All of this is brought on by a.... signal molecule
will shut down quickly when the.... signal molecule
Explanation:
The G protein-coupled receptors (GPCRs) are transmembrane proteins found on the plasma membrane. GPCRs are considered to be the most diverse group of transmembrane receptors in eukaryotic cells. These proteins (GPCRs) bind to signaling molecules to trigger signaling pathways through Guanine nucleotide-binding proteins (G-proteins). G proteins are signaling proteins (for example, Ras protein) that bind both GTP and GDP. After the signaling molecule binds to GPCR, GTP is hydrolyzed by the G-protein in a process that triggers specific signaling pathways (for example, activation of the production of second messengers).
The wife and husband are heterozygous, therefore, they have one dominate allele and one recessive allele. The little boy inherited both recessive alleles so he can't roll his tongue.
T = Dominate allele
t = recessive allele
Wife : Tt
Husband: Tt
Boy: tt
