Watch the video of a chicken wing dissection below to complete the lab sheet. In addition, observe the pictures of the labeled chicken wing. Note the similarities between the human arm and the chicken wing...are they homologous?? If you miss one or more of the days of the fetal pig dissection or if you have opted out from the dissection, complete the appropriate section for each day. Use the link below to complete each section: Fetal Pig Dissection Alternative Link
Complete your lab packet (also found below in digital format) by using the virtual dissection of a frog. If you missed one or both days, use the link below to complete the dissection.
The virtual dissection can be found on this website: Frog Dissection The microscope slide observations are also posted below in the slide show in the following order: frog skin, frog small intestine, frog heart, frog lung. Complete your lab packet (also found below in digital format) by using the virtual dissection of a perch. Also, use the picture of the fish scale below to make observations in your lab packet.
The virtual dissection can be found on this website: Perch Fish Dissection Watch the video below and follow along with the dissection of this lily flower. Complete your lab sheet as you go. Use the data below to complete the lab. You have been provided with the initial population numbers and how much the population will change for each generation; either increase by 20%, decrease by 20%, or stay the same (0%). Use the directions to help you to complete the rest of the lab.
In your lab 20 packet, you are to answer questions while observing diagrams that act as evidence in support of the theory of evolution. Use the instructions (posted below) to complete each part. The diagrams are posted below.
For Lab 18, we detected the presence of a genetic mutation using gel electrophoresis (from back in Lab 13!). Below is a picture of the gel from Lab 18. Use it to complete your analysis and determine the presence of a mutated gene. For this gel: Lane 1 control - homozygous for mutated allele, has sickle cell anemia; Lane 2 control - heterozygous for mutated allele and wild-type allele, carrier for sickle cell anemia; Lane 3 - homozygous dominant for wild-type alleles, does not have sickle cell anemia; Lane 4 - Mother of Child; Lane 5 - Child; Lane 6 - Father of Child
Use these pictures & data to complete your lab packet observing blood types and applying patterns of inheritances to blood types. If the sample is "positive" for agglutination, then there is a "+" next to the well. If the sample is "negative" for agglutination, then there is a "-" next to the well. For example, sample 1 is negative (-) for agglutination with Anti-A serum and is negative (-) for agglutination with Anti-Rh serum, but it is positive (+) for agglutination with Anti-B serum. Therefore, Sample 1 is blood type B-. Complete your data table in your lab packet and answer all questions.
Follow the instructions in the packet to complete pages 1 & 2. For page 3, use the data from the table below to complete your data table and finish the activity packet.
