The assortment of genes is determined by metaphase 1 and 2 because thisnis where the chromosomes line up and where they will be sent (and separated) is determined now.
<span>Two types of macromolecules: nucleic acid and protein.
Chromosomes are how the DNA is stored so they primarily contain nucleic acids. In addition to properly organize and condense the DNA, proteins are required. These include histones and other proteins.</span>

Parabiosis is an effective way to evaluate hormone function because it permits the exchange of only long-lived molecules (such as hormones) between the two joined individuals. Thus, the glucose levels of each mouse will stay the same, but the hormone levels will not. The db mutant's hormone level will decrease, and the wild type's hormone level will increase.
Coleman's goal was to determine if the ob and db genes function in the hormonal regulation of appetite and body fat. In this experiment, if both appetite-suppressing hormone and glucose were exchanged, it would be impossible to determine whether any weight changes in the mice were caused by the transfer of hormone or the transfer of glucose from one mouse to the other. For example, an increase in hormone level (and thus greater appetite suppression) could lead to weight loss, as could a decrease in glucose level. On the other hand, a decrease in hormone level or an increase in glucose level could lead to weight gain.</span>
If lions attack the slowest animal in a herd, it is beneficial to the herd in the following ways:
1.) Evolutionarily, the faster herd members survive and breed, increasing the speed of the offspring and guaranteeing better survival for the future population.
2.) The lions focus on the straggling animal, allowing the rest of the herd to escape.
3.) The death of one herd member ensures the survival of many more.
