I found the exercise on the internet and these were the options:
"A)Did this girl grow up in a single-parent mother-headed family?
B)Was this girl insecurely attached?
C)Did this girl have a stressful childhood?
D)<span>Does this girl have many siblings?"
Correct answer: D
The number of siblings is not a factor that promotes early puberty in girls. All the other factors do have an impact although the mechanisms are yet not very well known. When there is not a father figure present, girls tend to reach puberty earlier. When they are insecurely attached to their mother, girls also tend to reach puberty earlier. Lastly, another factor that may lead to an earlier puberty in girls is the stress they've passed through during childhood - mostly from family conflicts, whether with parents or siblings.</span>
Is this a multiple choice question? if yes the answer is c/organic!
The type of evolutionary mechanism, genetic drift
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.
In "Hydroelectricity" we build dam in order to produce electrical energy by rotating our huge turbines. As Dam separates the division of water into two parts, It can store/prevent flooding and protect community
In short, Your Answer would be "Hydroelectric Power"
Hope this helps!
