What is the difference between density-dependent and density-independent factors

Yes or no and why ? 1. Many different types of protists will be present in a sample from a single source..

Provide an example scenario in which the sampling protists would be used in the study of an environmental science issue?

Identify sources of error during the location and identification of the protists.

Please answer all questions please

1.Explain how the NGS approach has been able to bring the cost of sequencing down.

2.In a nutshell, what are the major steps performed during next generation sequencing of DNA? How do these steps differ in the Illumina platform as compared to the Roche 454 platform?

3. Now that the human genome has been sequenced, what types of information still need further research?

Please answer all questions please

1.Starting with normal and cancer intact cells as well as the preparation of the DNA microarray chip, explain in detail how the typical DNA microarray experiment will be performed in order to identify differentially expressed genes. What are the types of probes that can be used for this experiment, and how are they different? Explain how the data will be interpreted.

2.In a nutshell, describe the major advantages and disadvantages of each DNA sequencing platform

You have discovered a new strain of peach that is larger, sweeter and juicier. A karyotype reveals that it is tetraploid. Describe one way in which this new peach may have been generated. Use drawings if necessary.

What evidence suggests that the biochemistry of life elsewhere would resemble that on Earth?

Household septic systems include a tank that collects sludge and a porous leaching field that receives clarified effluent. How is this similar to or different from municipal wastewater treatment plants?

Why is the cloning reaction, transformation reaction, and pouring plates important for sequencing a plasmid? This is a lab-related question. We did cloning, transformation, and poured plates in lab, but why is this important for sequencing a plasmid? Please help me!!!

A. Write three ways that you can use the factor that was used to dilute a sample

B. One of your fellow classmates got sick after drinking coca cola (with ice) from a soda fountain at a local fast food restaurant. He claims that toilet water is cleaner than the ice cubes that are dispensed from the machine at the restaurant.

1.What organisms do you think causes contamination of ice dispensers? ...toilet water?

2. How could you test the water and conclude with water is “cleaner”? Show your work by creating an appropriate dilution schemes. So one scheme for the ice water and one scheme for the toilet water.
