Please describe how cancer cells develop and what role apoptosis plays in cellular homeostasis.
A Punnett square, devised by the British geneticist Reginald Punnett, can be drawn that applies the rules of probability to predict the possible outcomes of a genetic cross or mating and their expected frequencies. To prepare a Punnett square, all possible combinations of the parental alleles are listed along the top (for one parent) and side (for the other parent) of a grid, representing their meiotic segregation into haploid gametes. Then the combinations of egg and sperm are made in the boxes in the table to show which alleles are combining. Each box then represents the diploid genotype of a zygote, or fertilized egg, that could result from this mating. Because each possibility is equally likely, genotypic ratios can be determined from a Punnett square.
After reading the chapter and viewing the video, use a punnett square to plot out at least 2 traits within your own family ( eye color, ear lobe location) or any other trait that you find interesting..Please explain your findings. You can do eye color, brown.
Please give your understanding of biofilms and how they play a role in chronic diseases. How has excessive and unnecessary antibiotic use increased biofilms and antibiotic resistance? List at least 2 examples and how they may pertain to your work environment. My work environment is that I’m a firefighter paramedic. Check out the video link.

Lab 6: The Geologic Record This is a quick lab. You’ll need some blank paper, string, a metric ruler or meter stick, scissors, colored markers. a calculator and a camera. If you want passing credit, you must take the indicated images and upload them with your answer sheet or send them to me via Canvas messaging. The following exercises should be submitted for this lab: Lab 6: Lab 6 Geologic Record Answer Sheet (5 pts) Lab 6 Timeline (10 pts must include images) If images aren’t included, you won’t get a passing grade. List of Timeline Images (make sure the images are clear enough for me to read the papers) Eras at correct intervals along the string, Periods at correct intervals along the string, Each of the events at correct intervals along the string, Mass extinctions at correct intervals along the string, An image of yourself with your timeline with all the events in numbers 1-4 above.

In this discussion, lets talk about homeostasis.. You go for a long walk on a hot day. Give examples of ways in which homeostasis keeps your body healthy.
Watch this Discovery Channel video on thermoregulation to see illustrations of this process in a variety of animals.
Please write a lab report following the guidelines provided in the pdf. The experiment was performed as described in the other PDF. Everything is named accordingly. Pictures will be also available as soon as my instructor provides me with quality pictures (hopefully pretty soon). The question addressed during the experiment is: what are the morphological differences between dicty cells and L-fibroblasts cells? If any questions please do not hesitate to ask.
Although the scientific method is used by most of the sciences, it can also be applied to everyday situations. Think about a problem that you may have at home, at work, or with your car, and apply the scientific method to solve it.
Follow the outline of the scientific method as described in the chapter and submit your detailed steps (all 6 of them) to come up with your hypothesis.
A flow chart shows the steps in the scientific method.
In step 1, an observation is made.
In step 2, a question is asked about the observation.
In step 3, an answer to the question, called a hypothesis, is proposed.
In step 4, a prediction is made based on the hypothesis.
In step 5, an experiment is done to test the prediction.
In step 6, the results are analyzed to determine whether or not the hypothesis is correct. If the hypothesis is incorrect, another hypothesis is made. In either case, the results are reported.
