Summary Introduction

To determine: The stage of U.S. population on the S-curve.

Introduction: S-growth curve or sigmoid growth curve illustrates the growth of population in a new environment, where the density of population rises slowly initially and then exponential growth takes place and then declines with a negative acceleration phase and the population stabilizes at zero growth rates.

Summary Introduction

To determine: The factors that might cause the population to stabilize.

Introduction: The stability in the population comes at the negative acceleration phase when the growth rate becomes zero. When the fertility rate becomes equal to the mortality rate, the stabilization of the population occurs.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.
You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
