A 23-year-old woman presents to the OB-GYN office you work at. She was recently surprised to learn that she is pregnant. She estimates that she is about 8 weeks along. She tells you that she regularly drinks on the weekends with her friends. She asks you "Is that a problem? As long as I don't drink very much, I can still have a drink occasionally while I'm pregnant, right?"

Please correct my grammar's mistakes :)

Please correct my grammar's mistakes, thanks!

I chose to interview Dinh, who is an active, assertive person and a business major at ACC. Although he is not a math and science major, he has already taken a lot of different science and math classes. These classes include algebra, general chemistry one and two, general physics one and two, and geometry, etc. Right now, he is taking statistics and investments. Dinh told me that he likes business world, where he has a chance to meet and communicate with different kinds of people and where winners and losers are determined every day. He thinks that the harshness and competition in the business world will make him progress every day to perfect himself in life and he enjoys that. Dinh is open and friendly in my view. He is not a close friend, but he was willing to help me when I invited him to my interview for math’s real world examples. He seemed very excited for the interview, and he said that he is confident in his abilities to answer my questions. Dinh likes real world’s examples and so he says that he can start to answer questions now.

Before conducting the interview, I told Dinh that he will be a main character of the interview and my job is just asking him questions and no more than that. The purpose of the interview discovers and knows about his thinking and thought process when he answers questions. Therefore, he has a right to express his thoughts, whatever he thinks that describes correct answers to questions; feel free to share his ideas and don’t be shy to explain questions.

Compare and contrast feautures across phylum:

Porifera, Cnidaria, Ctenophora, Platyhelminthes, Nemertea, Mollusca, Annelida, Blastocoelomates (Phylums Rotifera, Nematode, Entoprocta), Arthropoda (Phylums Tardigrade, Onycophora), Echinoderms, Locophore (Phylums Phoronida, Ectoprocta, Branchiopoda), Protochordates (Phylums Hemichordate, Chordata)

What are the big issues related to their convergent evolution, solutions to the problem of their body plan?

What are their forms of development?

Diagram each phylum's water flow. C

ompare and contrast features across Phylums: circulatory system, gas exchange, feeding, syncytial or not, ciliated or not (in short)

Thank yoooou!

19) Core Concept: Information Flow- Explain how information from DNA results in the synthesis of a protein. Explain how information in the environment ultimately results in changes to gene expression.

20) Explain the steps in DNA recombinant technology (FROM GFP LAB). Include restriction enzymes, plasmids, heat shock, transformation and names of any enzyme that is needed in your answer.

21) Explain the purpose and/or what is happening at any step in the GFP lab protocols.

22) Predict how defects in the regulation of cell-cycle checkpoints would affect cells and explain how these defects relate to uncontrolled division in cancer and cancer progression.

DNA mutations can occur in a variety of ways. Choose one of the ways that DNA mutations can occur that you are learning about this week, identify and briefly describe it.

Then, choose a genetic mutation (it can be from your textbook, one you are aware of, or one you learn about through your research of this topic), and describe the type of mutation that it involves.

Consider if it affects the ability of the organism to produce proteins correctly, if it alters part or an entire chromosome, etc. Provide a picture of a karyotype or subject with this mutation (use of internet photos is fine, but remember to give credit to the photographer/illustrator). It can affect humans, animals, plants, bacteria - there are lots of different kinds!

Discuss with your classmates potential practical effects that one might see with this mutation, versus others. Please be sure to review your posts for accuracy in the discussion of these mutations (keep in mind that opinions and blogs do not always provide factual information, try to rely on journal articles and peer reviewed scientific research).
