Answer: 1. Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
2. The changes in our behavioral patterns and adaptations that are caused by these technological advances could prove to be the primary driving forces behind the next stage of evolution for our species. These members of the species are more likely to reproduce and pass their genes on to their children.
Explanation:
<span>It goes up consistently from 6-8 weeks gestation and to the highest
point of maximum of ~150% pre-pregnancy level, around 32-34 weeks. Facilitates
maternal/fetal exchange of: respiratory gases, nutrients, and metabolites, and
reduces impact of maternal blood loss at delivery. </span><span>
- Red cell mass increases by 20-30%. Smaller than the ~50%
increase in plasma volume. Net reduction in hemoglobin occurs.</span>
