Planning and Creating a Presentation In this activity, you will use presentation software to create a presentation of 15 to 20 slides explaining your arguments in support of or against the following statements: AIDS continues to be a global health crisis. AIDS still meets the definition of a pandemic. Your claims should be supported by scientifically complete evidence. Follow the steps provided to research, plan, and create your presentation. This guide about the research process can help. Part A: Ask Questions Begin by creating a list of questions to guide your research and help you form a convincing argument. Your presentation should answer some of these questions: What is the definition of a pandemic? How does a pandemic differ from an endemic or epidemic? What is the life cycle of the HIV virus once it enters the body? How does the genetic code of the virus change? How does HIV affect the body? How do people become infected with HIV? How does AIDS develop from an HIV infection? What are the current infection rates of HIV across the globe? Where is HIV/AIDS most prevalent? What treatments are currently available for HIV/AIDS? Do some regions of the world have better access to treatments than others? What is the average life expectancy for someone with HIV? Does life expectancy differ around the globe? Now write four additional questions about HIV/AIDS that could help strengthen your argument in the presentation. Part B: Find Credible Sources When designing a science presentation, look for credible sources. Science doesn’t show bias, but humans do. Avoid sites and articles that provide facts without citing proper scientific evidence. You must be able to identify reliable sites so that the data in your presentation is credible. Use sources that end in .gov, such as CDC.gov. These government sites are reliable sources. You can also use sites ending in .edu. They are usually trustworthy, but sometimes students, not scientists, write content for .edu websites. Always identify the source’s author before proceeding. Some .org and .com sites are credible, but it’s important to verify their authenticity. When reviewing a source, ask these questions: Who is the author? Is this person an HIV or AIDS expert? What is the document’s purpose? Does the document state facts that scientists can prove with evidence? Are there opinions in the document? How old is the document? Do other credible sources support the statements in the document? Search for credible websites and note the information they contain. Write down two sources that you will use for your presentation, and cite them using Modern Language Association (MLA) citation methods. Part C: Take Notes In a separate location, take notes from the sources you have identified. The notes will provide details for your presentation. While taking notes from texts and websites, use these reading strategies. In the space provided, write four pieces of information that you intend to use in your presentation. Part D: Organize Your Information After you’ve gathered research and answered all your questions, create an outline in the answer space. Following these guidelines for writing a five-paragraph essay may help you structure your outline. Be sure to account for the claim you’re making in your introduction, and include a works cited page at the end with the authors and websites you consulted. Part E: Select Audio and Video An audiovisual presentation uses pictures and words to clearly present information. These tips will help you effectively build your presentation: Limit text on your slides: Insert key words or phrases that highlight your points instead of typing your entire speech on the slide. When possible, use pictures instead of words: Use representative figures such as pictures, graphs, and charts to depict information or evidence rather than using huge blocks of text. Fill in your speaker’s notes: Presentation software includes a notes section where you can add speaker’s notes for your own reference. In this section, you can cover all the details you want to talk without showing them on your slides. Your speaker’s notes should be clear and coherent enough so that someone else could deliver the presentation to an audience. You must complete your speaker’s notes to get full credit for the assignment. List two to three audio, video, or photo resources that you wish to use in your presentation and paste them in the provided space. Part F: Create and Deliver Your Presentation Use your outline and the materials you’ve collected to create your presentation. It should contain 15 to 20 slides. Be sure to proofread and revise your writing to catch any errors in grammar, spelling, logic, or cohesion. Remember that you must add speaker’s notes as well as a works cited page at the end.

In a population of lizards, allele T (TT and Tt) codes for long tails. The frequency of allele t (tt) which codes for short tails is 60%. In this population, it was found that having a longer tail tricked the predators into thinking it was a snake and scared them away, which of the following is most likely to occur over time.
Question 20 options:
the frequency of the two alleles will change until they both equal 50%
there will be no change in frequency since T is dominant
the frequency of T will decrease since it is dominant
the frequency of T will increase, and t will decrease
Answer:
The frequency of T will decrease since it is dominant
Explanation:
Since having a long tail provides a survival advantage, individuals with the T allele are more likely to survive and reproduce, passing on their T allele to their offspring. As a result, over time, the frequency of the T allele is likely to increase, and the frequency of the t allele will decrease.
The fact that T is dominant does not affect the frequency of the two alleles in the population, but it does determine the physical expression of the trait in individuals that have at least one T allele.

Choose TWO of the following statements about adaptation. For each statement you chose, explain why that statement is true using evidence from the simulation.
Statement 1: Organisms with an advantageous trait are more likely to survive and reproduce.
Statement 2: Over time, the proportion of the population with the advantageous trait will increase.
Statement 3: If the environment changes, a different trait could be more advantageous.
Statement 1: Organisms with an advantageous trait are more likely to survive and reproduce.
Explanation: Adaptation is the process by which organisms change over time in response to changes in their environment.
Statement 2: Over time, the proportion of the population with the advantageous trait will increase.
Explanation: As mentioned in Statement 1, organisms with advantageous traits are more likely to survive and reproduce, leading to an increase in the proportion of the population with those traits.
What is right about adaptation?Organisms with traits that are advantageous in their environment are more likely to survive and reproduce, passing those traits on to the next generation. For example, if a population of plants is exposed to a change in temperature, those plants with traits that allow them to tolerate the new temperature will be more likely to survive and reproduce, increasing the proportion of the population with those advantageous traits over time.
The second is known as natural selection, which results in the survival of the fittest. Over time, the population will shift towards individuals with advantageous traits, leading to an increase in the proportion of the population with those traits. For example, in a population of birds, those with longer beaks may be better equipped to feed on a certain type of seed, leading to increased survival and reproduction of those birds, and eventually leading to a population where the majority of individuals have longer beaks.

What is condensation reaction?Condensation reaction is a type of chemical reaction where two smaller molecules combine to form a larger one, resulting in the elimination of a smaller molecule, typically water. This process is also known as a dehydration reaction, as it involves the removal of water from the reacting molecules. Condensation reactions are vital in the formation of macromolecules, such as carbohydrates, proteins, and nucleic acids, and play a crucial role in many biological processes. They are also commonly used in synthetic organic chemistry for the synthesis of more complex molecules, such as polymers and drugs. The reverse of a condensation reaction is called hydrolysis, which involves the breaking of a larger molecule into smaller ones with the addition of water.
