Answer:
Sugar molecules do NOT provide all the elements needed to make the four types of macromolecules.
Explanation:
This is because proteins, and amino acids need more types of elements than carbohydrates and lipids do. In nucleic acids, the elements are carbon, hydrogen, oxygen, nitrogen, and phosphorus. Notice that sugar molecules do not have either nitrogen or phosphorus. This same principle applies to proteins, which the elements of it are carbon, hydrogen, oxygen, and nitrogen.
Cocaine induces a sense of exhilaration by increasing the availability of dopamine and serotonin in synapses. Cocaine is among the powerful stimulants which increase the release of neurotransmitters such as nor-epinephrine, dopamine and serotonin, that affect CNS and PNS activity. Cocaine administration constricts blood vessels that are absorbing it, son snorting it is a slow way to deliver it to blood stream and eventually the brain.
Answer:
option C: B = 0.48; b = 0.52
Explanation:
Of the 50 mice, 12 were homozygous black (BB), 24 were heterozygous black (Bb), and 14 were brown (bb).
BB Bb bb Total
12 + 24 + 14 = 50
the formular for alleleic frequency (p) is (BB+ Bb/2) / total,
q = (bb + Bb/2) / total
Allelic frequecy of B (p) is (12 + 24/2) /50 = 12 + 12 = 24/50 = 0.48
Allelic frequency of b (q) is (14 + 24/2) / 50= 14 + 12 = 26/50 = 0.52
check p + q = 1; 0.48 + 0.52 = 1
