How can you experimentally demonstrate that a specific GPCR couples through Gi alpha subunit to inhibit adenylyl cyclase activity

Identify the trophic levels in a food chain and explain how energy is transferred through the various trophic levels

Fly-fishermen use artificial insect imitations (flies) to catch trout, and typically release them again in order to have the fun of trying to catch them again later. One fisherman claims that due to the “catch-and–release” practices, the trout are becoming harder to catch, and explains that the ability to detect fisherman’s flies is being passed on by released trout to their offspring, making them harder to catch. Explain whether he is right or wrong.

DESIGN YOUR OWN EXPERIMENT

As a future scientist, you have the opportunity to show your laboratory skills by designing your own experiment. Below you will be provided an experimental question. Your job will be to physically complete an experiment to test the hypothesis associated with your question. Once again, you must conduct the actual experiment and document it. Use your Experimental Planning Form to guide you through the experiment. Keep in mind the overall goal is to conduct a valid experiment using the scientific method!!!!!

Topic: What is the effect of salt on the boiling temperature of water?

Below are more helpful pointers of details of how to document your experimental process.

Title

This should be short, but describe the experiment.

Problem Statement

What scientific question are you planning to investigate?

Background Information

Write a short paragraph describing some background information that you have learned about the topic of your investigation.

Hypothesis

You will propose a possible outcome for your experiment that includes the data that will support your hypothesis.

Materials List

Make a list of all of the materials you will use to complete your experiment.

Include consumable supplies and lab equipment in your list.

Procedure

This section must be written in a step-by-step numbered format, so that another student who is not in your group can follow it.

You can draw a picture to show how you will set-up your experiment (optional).

SAFETY – List what lab safety equipment you will need.

Data Table

Your data table should include a title, column headings, units (if needed) and a place to record all data from your experiment.

You must show at least three trials of data for your experiment, so be sure to leave room in your data table for all trails.

Conclusion Paragraph 1 –

Your conclusion should state if your data DID support your hypothesis or your data did NOT support your hypothesis and why (use data for support).

Summarize your data in a few sentences.

Paragraph 2 –

Explain what you learned about the problem statement from the experiment.

List some errors you and your partner(s) could have made while conducting the experiment that could affect your results. YOU MAY NOT SAY “NOTHING WENT WRONG” OR “THE EXPERIMENT WENT WELL”. Think here!!!!

PLEASE TYPE OUT ANSWER AND ANSWER COMPLETELY.

What are fresh fruits more prone to microbial contamination, when compared to dried fruits?

what are different forms of cholesterol present in human body. How do those different types impact heart health?

Why is the purpose of using food additives?

what is agglutination and relate it to specific immunity.

1) Some researchers have argued that paraphyletic groups are not “real” and should not be used in scientific discussions. What do you think?

2) The fact that organisms evolve by natural selection means that adaptive explanations make sense in biology. Does this mean that every organismal trait has an adaptive explanation?

Part A - Identifying the Processes of Replication, Gene Expression, and Recombination

This activity requires that you correctly identify the processes of DNA replication, gene expression, and recombination by matching images to brief descriptions of each process.

What is epithelial-mesenchymal transition? Name couple examples.

Step 1: If 75 kg of "Molecule Z" is distributed amongst 5,000 organisms that weigh 2 kg each on average, what is the concentration, by mass, of "Molecule Z"?

Step 2: Assuming that 70% of "Molecule Z" from above is lost between trophic levels, and the next trophic higher level consists of 10,000 individuals weighing 0.1 kg each, what will the concentration of "Molecule Z" be in this next higher trophic level? (Hint: remember that what is not lost is what is passed to the next trophic level).

7) _photosynthesis___ is the process that involves rubisco fixing oxygen instead of carbon dioxide, resulting in a depletion of organic material in the Calvin cycle and an overall reduction in photosynthetic activity.

8) Noncyclic electron flow in the photosystems produces ATP

Parasitic plants have lost many of the morphological and generic traits necessary for an autotrophic lifestyle. From an evolutionary point of view, how do you think this happened?

1) Explain how this cellular mechanism affects variation: Crossing over

Briefly explain how the mechanism (crossing over) could contribute to genetic variation in offspring. Be specific how this mechanism gives this result, when it occurs during the cell cycle, and be specific as to the type of genetic variation produced (from base-pair sequences to whole genomes).
