True/Falsewhen a plant fertilizes itself is there still genetic variation between the offspring and the parent
Yes, there can still be genetic variation between the offspring and the parent when a plant fertilizes itself.
This is because the plant can still undergo meiosis, which is a form of cell division that results in the production of four daughter cells, each of which have a different combination of genetic material from the parent. This can cause genetic variation between the offspring and the parent, even when the parent is self-fertilizing.
Meiosis is a type of cell division that creates daughter cells with half the number of chromosomes as the parent cell. In plants, meiosis occurs in the anthers and ovary, which are the male and female reproductive organs, respectively. During meiosis, genetic material from the parent cell is recombined and shuffled, which results in the production of four daughter cells that can have different combinations of genetic material from the parent.

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.

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.

nucleophilic addition of a carbonyl group under basic conditions takes place with which of the following?a. protonation of the carbonyl oxygenb. formation of a carbanionc. formation of an alkoxide iond. protonation of the carbonyl carbon
The nucleophilic addition of a carbonyl group under basic conditions takes place with the formation of a carbanion. The correct answer is B.
A carbonyl group consists of a carbon atom double-bonded to an oxygen atom, and it is a common functional group in organic chemistry. When a carbonyl group is subjected to basic conditions, the carbonyl oxygen is deprotonated, forming a negatively charged species called a carbanion.
The carbanion is highly reactive and can act as a nucleophile, meaning that it can donate electrons to form a new bond. In the case of a carbonyl group, the carbanion attacks the carbonyl carbon, forming a new bond and resulting in the formation of a new molecule.
This reaction is known as nucleophilic addition to the carbonyl group, and it is a fundamental reaction in organic synthesis. The type of molecule formed depends on the nature of the nucleophile, and it can be a variety of compounds such as alcohols, amines, or even cyclic compounds.
In summary, the nucleophilic addition of a carbonyl group under basic conditions occurs due to the formation of a carbanion, which acts as a nucleophile and attacks the carbonyl carbon, leading to the formation of a new molecule.
