Describe the common pattern of alternating extinctions

In our online lecture we include a quote by E. O. Wilson, “The one process now going on that will take millions of years to correct is the loss of genetic and species diversity by the destruction of natural habitats. This is the folly our descendants are least likely to forgive us.”

Throughout Earth’s history, we have had long periods of innovation and radiation of new species which have been interrupted periodically by five major extinction events that eliminated large percentages of the life on Earth. The last of these appears to have involved a collision with a large asteroid resulting in the loss of the dinosaurs at the end of the Cretaceous. Each of these events has been followed by a new period of radiation of new species and innovation.

As Wilson states, we are now in the midst of a sixth major extinction event that has been brought on by the actions of humans.

Describe the common pattern of alternating extinctions and radiations. Consider Wilson’s statement. What evidence can you find to support or refute that statement? Do you agree with Wilson? Explain why you do or don’t agree and present the evidence supporting your opinion.

Explain the comparison between endocrine and nervous system

Q1. An efficient DNA probe can sometimes be developed by knowing the amino acid sequence of the protein encoded by the gene. A student argued that this is too time-consuming as the complete amino acid sequence must be determined in order to create the probe. Does the student have a valid argument? Why or why not give details?

Q2. Both endocrine and nervous system are major regulating system of the body; but nervous system has been compared to an airmail delivery system and the endocrine to pony express. Briefly explain the comparison.

Explain the relationship between chromosomes and dna

Review information on genetic disorders on the National Human Genome Research Institute Site: http://www.genome.gov/.

Choose a genetic disorder that can be inherited from a parent. Write a 525- to 700-word paper on the genetic disorder. Include the following in your paper:

Summarize the Chromosomal Theory of Inheritance and how chromosomal abnormalities can lead to genetic disorders.

• Describe the relationship between chromosomes and DNA.

• Identify an example of a genetic disorder and describe the genetic disorder including symptoms, impact on quality of life, and life expectancy. How common is this disorder? Does it run in specific ethnic bloodlines?

Format your paper according to APA guidelines. Review the Academic Writing Guidelines video and the Center for Writing Excellence for additional guidance on academic writing and APA style.

Consequence to earths ecosystems

Q1

Is it possible (economically, socially, environmentally) to have zero emissions of pollutants? What level of risk are you willing to live with? What level of risk are you willing to allow for environmental health?

Q2

What would be the consequence to Earth’s ecosystems if the ozone layer were to completely dissipate? Are certain organisms, landscapes, environments more at risk if this were to happen?

Q3

What is the difference between primary pollution and secondary pollution? Which is easier to control? Why?

Q5

Don’t like any of these questions? Ask one of your own, and then answer it.Note that your question should be substantive, just like your answer, and the question should be in a format that invites further discussion. Avoid questions like “Why are kittens cute?” or “Are sharks vicious?”
