The three questions are basically looking for an observation, asking the question and then giving the hypothesis, and then trying to prove it with simple experiments. Somebody help. Thank you!

1.State your observable events or a set of questions you are interested in understanding. For example, you ask why a flock of birds fly in a certain pattern
2. Clearly state your hypothesis that fits your observations.

3. Design a simple experiment to test your hypothesis. （namely, measurable outcome, proper control, enough sample number, randomization, and plausibility）



The following is the newly added information
1. You make an observation around your life, which can be either science-related or not. For example, you could watch a flock of birds flying in the sky in a certain pattern.

2. You then can ask a question on your observation. For example, you ask why a flock of birds fly in a certain pattern.

3. It is a time to formulate a good hypothesis based on the class discussion and your own research in the internet. In class, we discussed that a good hypothesis has to be a single sentence, which can be conceptually clear, testable by experiment, specific or precise, and must include both dependent and independent variables (cause and effect).

4. You have to propose an experiment which you can satisfy all six criteria we discussed in class, namely, measurable outcome, proper control, enough sample number, randomization, and plausibility. However, it is a proposed experiment, not an actually experiment you have to do. This means you need to clearly explain what and how you will perform to prove your hypothesis using inductive and deductive reasoning. As we discuss in class, a good experiment will result in “yes” or “no” answer. Since you will NOT perform the actual experiment, you can’t really predict the outcome. That means I will check whether you used a logical reasoning in designing your experiment to prove that your hypothesis is correct.

In one type of genetic therapy, healthy cells are introduced into diseased tissues. Which of the following is a serious problem with ​this kind of therapy?
​A) It is technically very difficult to transfer cells into tissues
​B) Rejection of the introduced cells by the recipient’s immune system
​C) Since each person’s DNA is unique, the donor DNA may not function in the recipient’s tissues
​D) Every person has different cell types
Which of the following is true about the process of crossing over of chromosomes?
​A) It ensures that replication of the chromosomes is as error-free as possible
​B) It acts to ensure that the gametes that result from meiosis are all genetically alike
​C) It increases the genetic diversity of gametes by creating chromosome types that are not identical to any ​​​​​​​​​maternal or paternal types
​D) It happens during mitosis as well as meiosis
​
Which of the following gives a good idea of what the science of genetics is all about?
​A) Genetics tries to establish patterns and mechanisms of heredity of traits from generation to generation
​B) Genetics tries to work out the rules and processes governing overall cellular metabolism
​C) Genetics focuses on mitosis and DNA replication more than anything else
​D) Genetics, unlike other branches of science, does not proceed by the scientific method, since it is nearly impossible to do ​​​​meaningful genetics experiments

Draw a quick sketch of mitosis next to meiosis I and meiosis II. You can do it on paper, or on your screen if you have a touchscreen. Compare and contrast them to highlight 3 similarities and 3 differences. Make sure your diagram is CLEARLY labeled

Now draw meiosis with a cell that is diploid and has 3 different sets of chromosomes (that means there is a chromosome 1, 2, and 3, with 2 copies of each). Make sure that chromosomes 1, 2, and 3 are visually distinct

: Draw a sketch of meiosis but add a nondisjunction event to it (you can pick meiosis I or II). For each final daughter cell, CLEARLY identify whether there are any issues with it – does it have the correct set of chromosomes? If it was combined with another gamete to create a zygote, will the resulting zygote have too many or too few chromosomes? Is it missing any chromosomes completely?

How do I do this> what should I model this after?

Step 1:

Perform research to find at least two articles on the following topic: “The effects of climate change on polar bear populations”. You must find one article based on primary research and one based on secondary research. After reviewing the articles, recreate and complete the table below which you will submit for feedback.

Article 1 Article 2
Source
Purpose of the periodical
(news website, newspaper, journal)
Type of source: primary or secondary?
Type of article: scholarly or non-scholarly
Type of language used in article (describe)
Intended audience - who is the article written for?
Main point or main message of the article
How does the title catch attention?
Does it accurately depict the main message?
List any opinions stated in the article.
(Who’s opinion are they?)
How many authors?
How many people interviewed in the article
(not applicable if this is original research)
How many sources listed in the bibliography or sources list?

Step 2:

Write a 1-paragraph summary of the comparison. Which one is the primary source? How are primary and secondary sources different from each other? Similar to each other? How can you tell which is which? You will submit this paragraph for feedback.

  • five different eukaryotic species
  • For each species:
    • Discuss how to identify the organism. This includes how you could identify it in a lab, or defining visible characteristics.  (2/2, 2/2, 2/2, 2/2, 2/2 points).
      • Consider a physical description (how many legs, type of skeleton, what does it look like, what color is it, what type of hyphae, etc)
    • Describe a clinical disease this organism is responsible for, and some signs and symptoms of such disease, as well as prevention and treatment.
    • Discuss some epidemiological statistics of the disease, or specific economic impact
      • Remember, these must include actual numbers and facts
    • Discuss an organism that could mimic this one, and how can you tell the difference between the two?
