Answer:
They can use these printers to make replica or identical copies of things like fossils. Theses are mostly useful because real fossils are rare so they can still study them without possibly ruining an artifact.
Explanation:
Answer: lower reproductive potential
Explanation: Evolutionary psychologists focused on what today is sociobiological approach to sexuality shaping the pattern of human sexuality. This considers that women's parental investment in reproduction is greater than men's, because human sperm is more abundant in quantity than eggs, and the fact that women must carry their young in the womb for several months as well as nurture them for a considerable time after birth. This tends to make women more selective in their choice of mates than men and is seen as a limiting factor in regards to sexuality compared to men.
According to social learning theory however, sexuality is a learned behaviour which arise from studying our environments. The attitudes of parents and grown ups in the society tend to shape our perspectives and expectations which expressing sexuality is a part of.
Answer:
binding regulatory subunits and inducing their release from the catalytic subunits
Explanation:
cAMP molecules diffuse into the cytoplasm where they bind to an allosteric site on a regulatory subunit of a cAMP-dependent protein kinase ( protein kinase A, PKA).
-In its inactive form, PKA is a heterotetramer comprised of two subunits namely, regulatory (R) and two catalytic (C) subunits.
-The regulatory subunits normally inhibit the catalytic activity of the enzyme. cAMP binding causes the dissociation of the regulatory subunits, thereby releasing the active catalytic subunits of PKA.
-cAMP stimulates glucose mobilization by activating a protein kinase that adds a phosphate group onto a specific serine residue of the glycogen phosphorylase polypeptide.
