To explain: Whether more evidence is required or not before taking action.
Concept introduction: Global warming is the effects of the increase in the average temperature of the climate system of the earth. The global warming is predominantly due to man-made causes. Emission of greenhouse gases and burning of fossil fuel have added to the rise in average temperature. Several effects of global warming are disastrous, which is of great concern as the actions to curtail global warming are getting delayed.
To explain: Whether it is better to reduce CO2 emissions.

To explain: The possible costs and benefits of the two strategies to wait until more evidences are gathered or act right now to reduce CO2 emissions
Concept introduction: Emission of greenhouse gases and burning of fossil fuel have added to the rise in average temperature. This causes global warming. It is predominantly due to man-made causes. Several effects of global warming are disastrous, which is of great concern as the actions to curtail global warming are getting delayed.

- Describe one way in which Public Health professionals have tried to combat the problem of poor diet, obesity, and or inactivity in the US. Describe the full scope of this strategy/and or intervention. How did it work to combat poor diet, obesity, and or inactivity ? Identify and describe one challenge for implementation of this strategy/intervention. 2. Would this strategy be classified as regulation or education? 3.How does this strategy/intervention fit with the Health Belief Model, Stages of Change model or Ecological model? 4. Was this intervention/strategy successful? Why or why not?arrow_forwarddescribe one way in which Public Health professionals have tried to combat the problem of tobacco use in the US. Describe the full scope of this strategy/and or intervention. How did it work to combat tobacco use? Identify and describe one challenge for implementation of this strategy/intervention. 2. Would this strategy be classified as regulation or education? 3. Was this intervention/strategy successful? Why or why not?arrow_forwarda) Find a nitrogen base. What carbon is the base attached to? b) What two nitrogenous bases are held together by 2 hydrogen bonds? c)What two nitrogenous bases are held together by 3 hydrogen bonds?arrow_forward
- You will be building a double-stranded DNA molecule, representing a short (20 base) sequence that could be found in a chromosome. It will have a 3' --> 5' strand and a 5' --> 3' strand. Use two full 12-base-pair DNA models. a) Upload a photo of a model once the first 6 nucleotides have been inserted to base pair with the two parent strands. b)Upload a photo of DNA polymerase I and Ligase in "action" removing the RNA primer nucleotides and making new phosphodiester bonds. c)Upload a photo of the final two DNA strands, after Termination, identifying the parent and daughter strands of each.arrow_forwardWrite down the 12 base-pairs (ex A-T or G-C) contained in the two models you will us from top to bottom below Model 1 bp: Model 2 bp:arrow_forwarda) What type of bond does helicase break? b) Which of these two types of bonds is stronger? c) Describe why it is necessary for the lagging strand to be made in fragments, called Okazaki fragments.arrow_forward
- a) How are the model single nucleotides structurally different than real-life dNTPs? b)If you wanted to make these DNA nucleotides into RNA nucleotides, what could you do to them? c)Name the type of bond that is being formed by DNA Polymerase III.arrow_forwardYou will be building a double-stranded DNA molecule, representing a short (20 base) sequence that could be found in a chromosome. It will have a 3' --> 5' strand and a 5' --> 3' strand. Use two full 12-base-pair DNA models. a) Upload a picture of your model reflecting the Initiation phase of DNA replication. b) Upload a picture of your model once it has entered the Elongation phase of DNA replication, showing the action of Primase. c)Upload a picture of your model once it has entered the Elongation phase of DNA replication, showing the action of DNA Polymerase III.arrow_forwarda)What region of the DNA do general transcription factors and RNA polymerase bind to? b)Where, in a eukaryotic cell, can one find TFs? c)What are the TFs called that bind to Enhancer Sites? d)Describe the role of Activators and Repressors in development.arrow_forward
