Analyze the results by answering the following questions. You may wish to do some reading in your text or on the web about human

survivorship to help you in formulating quality responses.
Compare the survivorship curves for males against those for females.
Explain the differences and why they occur.


Suggest possible biological and social/historical causes. For example, evolutionary


theory implies that females in the child-bearing years suffer higher mortality from childbirth deaths. How and in what periods do your data reflect this tendency?


Describe changes in mortality for males as a result of war.



Analyze and compare the mortality rates for the older age groups.
In general, why should these rates be higher than the average?
If you did not make a survivor curve for a nineteenth- century population, predict
how it would differ in three ways from the more recent population data you did plot.
If you did plot an additional curve from the nineteenth century, describe and explain
how if differs in three ways from the other one you plotted.

Describe how the survivorship curves of a more developed country (MDC) might compare to those of a less developed country (LDC).

Discuss how the survivorship curves could be used to make judgments about environmental and health conditions in each of the countries.

Humans are generally classified as forming a Type 1 survivorship curve.
Describe what this means.
Name some other organisms other than humans that are generally Type 1.
What are some distinguishing characteristics of Type 1 organisms?

Describe the fate of cells with or without cell walls in various "tonic" solutions (hypertonic, hypotonic, etc.).
hichkok12 [17]

Answer:

In hypertonic solutions, the cells will shrink and in hypotonic solutions the cells will fill up

Cells with cell walls will be able to control their tonicity better than cells without cell walls.

Explanation:

Cells with cell walls

  • In a hypertonic solution (high solute concentration), water will flow out of the cell into the solution until equilibrium is reached. If the solution has a high concentration of solute the cell may undergo<u> plasmolysis where the plasma membrane detaches from the cell wall.</u>
  • In a hypotonic solution: Water will flow into the cell because it has a higher solute concentration compared to the solution. This will continue until the cell is <u>turgid</u>. If more water continues to enter the cell, the cell is at risk of bursting, this takes a while because the cell wall will withstand the pressure.

Cells without cell walls

  • In a hypertonic solution: Water will diffuse out of the cell, however there is no cell wall so cell is in danger of shrinking and dying.
  • In hypotonic solution: Water will diffuse into cell,the cell will become turgid and if water keeps moving in the cell will burst because it has no cell wall to resist the pressure.
