a.

Summary Introduction

To draw:

The general shape of age and structure diagrams characteristics of (a) expanding, (b) stable and (c) shrinking population. And also explain why an individual can predict the next several decades of growth by the current age structure of populations.

Introduction:

Age structure graph is also called as population pyramid that shows the distribution of different age groups individuals within a population. Vertical axis of graph shows the different age groups of an individual while horizontal axis shows the gender of an individual. This diagram is used to predict the age distribution and growth of future population.

b.

Summary Introduction

To determine:

The general shape of age and structure diagram characteristics of a stable population.

c.

Summary Introduction

To determine:

The general shape of age and structure diagram characteristics of shrinking population.

"One of the symmetry breaking events in mouse gastrulation requires the amplification of Nodal on the side of the embryo opposite to the Anterior Visceral Endoderm (AVE). Describe one way by which Nodal gets amplified in this region." My understanding of this is that there are a few ways nodal is amplified though I'm not sure if this is specifically occurs on the opposite side of the AVE.  1. pronodal cleaved by protease -> active nodal 2. Nodal -> BMP4 -> Wnt-> nodal 3. Nodal-> Nodal, Fox1 binding site  4. BMP4 on outside-> nodal  Are all of these occuring opposite to AVE?
