Description

Characteristics of Living Things

Defining life can be very difficult. Scientists don’t all agree on a standard list of characteristics that define all life, but most generally agree on a common set of properties. Many of these properties are not limited to living things; some nonliving things may share a few of these characteristics as well. For instance, viruses don’t have the necessary machinery to reproduce themselves; they must use cellular hosts to make more viral copies. Because they cannot reproduce, they are not considered living.

Case Assignment

Your Assignment:

What is life? Research six specimens from the list below, describe them as living, nonliving, or dead and give support for why each belongs in their respective category.

Brown grassWhale spermHIV virusFertilized chicken eggHair from a human headPrionEgg from a grocery storeSkin cell from the back of the handAmoebaBlood cellMushroomCoral reef

Organelles can contribute to disease states in many ways. First, the organelle itself may be dysfunctional either because it contains one or more defective genes that impair its function or because it has been damaged by exposure to harmful substances such as chemicals, heavy metals or oxygen radicals. Additionally, an organelle can accumulate damage from processes occurring elsewhere in the cell. In this assignment, you will explore how normal cellular functions can be disrupted by dysfunctional organelles.

CASE ASSIGNMENT

There are many diseases that are caused by the malfunction of specific organelles. Three examples are listed below:

  • I-cell disease
  • Progeria (also known as Hutchinson-Gilford Progeria Syndrome)
  • Mucopolysaccharidoses

Select one of the disorders below and complete an essay of approximately 2-3 pages in length, addressing the questions below. A link is provided to introduce you to each disorder. You will need to conduct additional research to fully complete your essay. You should consult a minimum of three quality sources when researching parts I-IV below to complete your essay. Be sure to include which organelle(s) are malfunctioning and why in your essay.

I. Cellular cause of disease

Describe the type of cell(s) involved with the disease. What is the specific function of this type of cell? If an organelle or other cell structure is the problem in the disease, include information about it. Are there more of a specific type of organelle in this type of cell? Why is the cell not performing properly in this type of disorder? Does this disorder affect other parts of the body?

II. Disease- Basic Information

Describe what someone with the disease would notice, and what doctors find when doing an examination. How serious is the disease? What happens if it is not treated? What effect does it have on normal living? Is it inherited? If so, describe the inheritance pattern and the gene responsible. How does the malfunctioning cell cause the symptoms? Usually there is a protein or enzyme that isn’t produced properly. How is this related to the symptoms?

III. Disease Treatment and Research

How is the disease currently being treated? Is it curable, or is the treatment only for the symptoms? What research is currently being conducted to find a cure/treatment? Is there hope for a cure/treatment? Are stem cells or gene therapy used in research? Can these therapies lead to a cure? Why is continued research important?

IV. Summarize your findings.

volution is the change in populations over time. The frequencies of genes in a population change which results in changes in characteristics. The fossil record, biochemical evidence, genetic evidence, and other observations clearly show that these changes have occurred and are continuing to occur.

The mechanism for changes in populations is natural selection which is the differential survival and reproduction of individuals based on genetic differences among them. Organisms produce many more offspring than can survive. Because individuals have genetic differences, some are better able to survive and reproduce in a given environment. Populations change over time because of differences in individual survival and reproductive success.

Darwin observed that organisms often compete for mates. As a result, some individuals may produce many more offspring than others. For example, a peacock with brightly colored feathers and a complex courtship display is more likely to attract the attention of peahens and have an opportunity to pass his genes to the next generation. Male elephant seals compete with each other for breeding territories on beaches. A male without a territory is usually unable to attract females. The biggest, most aggressive males are usually the most successful. The advantage of having a large number of offspring outweighs the costs and perils. At some point a balance is reached between reproductive success and the costs of secondary sexual characteristics that can reduce survival (such as having bright feathers that attract predators as well as mates for example).

It is important to understand that natural selection impacts the population not the individual. The individual cannot evolve, but can only live or die, have offspring or not. The overall effect of natural selection is on the population.

  4. Sexual selection is a “special case” of natural selection. Define sexual selection (explain the concepts of male competition and female choice in your answer)
  5. How do the unique traits of the animal you have chosen increase its fitness (in reproductive terms)?

ASSIGNMENT EXPECTATIONS

Organize this essay assignment using subtitles that summarize the topic from each question above. For example, to answer Question 1, use a descriptive subtitle like the following: Natural Selection and Evolution..

One of the more important evolutionary concerns facing humans today is the impact on present day environments and populations. Consider how evolutionary processes may be impacting the fields of medicine, agriculture or the environment. Research topics such as antibiotic resistance, pesticide use (resistant insects/plants) or “recent” changes in human traits such as the theory of the “shrinking brain.”

Describe your chosen research topic on recent evolutionary processes. Explain how the evolution of rapidly changing populations or traits may be affecting humans in modern day society. Compare and contrast your research with that of your classmates.
