Match each definition with given terms

1. Large family of structurally related, secreted, dimeric proteins that act as hormones and local mediators to control a wide range of biological functions in all animals.	A. Rho
2. Cell-surface receptor in which the cytoplasmic domain either has enzymatic activity itself or is associated with an intracellular enzyme.	B. TOR pathway
3. A crucial signaling protein in the PI-3-kinase–Akt signaling pathway, so named because it is the target of rapamycin.	C. Enzyme-coupled receptor
4. A kinase that is involved in intracellular signaling pathways activated by cell-surface receptors and that phosphorylates inositol phospholipids at the 3 position of the inositol ring.	D. Phosphoinositide 3-kinase
5. A group of monomeric GTPases that regulate both the actin and microtubule cytoskeletons.	E. (TGFβ) superfamily
6. Cytoplasmic tyrosine kinase present at cell–matrix junctions in association with the cytoplasmic tails of integrins.	F. Focal Adhesion Kinase

Consider the ABO “blood type” gene. This single gene has three alleles called A, B, and O. There are four resultant “blood types” (phenotypic classes), as follows:

                                     

Assume Hardy-Weinberg equilibrium,  the frequencies of the A and B alleles are 0.26 and 0.07, respectively. What is the frequencies of the four blood types such as A, B, AB  and O in Norway;
