2. 25/100= 25 of 100 equal parts, 1/4= 1 of 4 equal part, and the decimal 0.25
3.110/100= 110 of 100 equal parts, 11/10= 11 of 10 equal parts, and the decimal 1.1
4. 1/2, because the shaded part (1)is half of the other part(2)
2/4,because the shaded part(2)is half of the other part(4)
3/6, because the shaded part (3)is half of the other part(6)
4/8,because the shaded part(4) is half of the other part(8)
Answer:
Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion. The role of chemical digestion is to further degrade the molecular structure of the ingested compounds by digestive enzymes into a form that is absorbable into the bloodstream.
Explanation:
Although peer pressure can influence adolescents’ alcohol use, individual susceptibility to these pressures varies across individuals. The dopamine receptor D4 gene (DRD4<span>) is a potential candidate gene that may influence adolescents’ susceptibility to their peer environment due to the role dopamine plays in reward sensation during social interaction. We hypothesized that </span>DRD4<span> genotype status would moderate the impact of 7th-grade antisocial peer pressure on 12th-grade lifetime alcohol use (</span>n<span> = 414; 58.7 % female; 92.8 % White). The results revealed significant main effects for antisocial peer pressure, but no main effects for</span>DRD4<span> genotype on lifetime alcohol use. Adolescent </span>DRD4<span> genotype moderated the association between peer pressure and lifetime alcohol use. For individuals who carried at least one copy of the </span>DRD4<span> 7-repeat allele (7+), antisocial peer pressure was associated with increased lifetime alcohol use. These findings indicate that genetic sensitivity to peer pressure confers increased alcohol use in late adolescence.</span>
