pict Experimental Planaria #1 Cut in half into front (anterior) and rear (posterior) Day 1 Measuring the Planaria This operation is best performed by removing some of the water from the dish into the lid with a clean pipette and waiting for the worm to stretch out. Measure the length of the worm in millimeters. (Always replace the water right away, you can use the dish lid to transfer water to and from the planarian environment.) A. Record the length of the front (anterior) section just AFTER you cut. This is your INITIAL front length: 5 m m B. Record the length of the rear (posterior) section just AFTER you cut. This is your INITIAL rear length: 3mm C. Observe and record any behavioral responses just after your cut Day 2 Spend time under the microscope observing the cut Planaria. Answer the following questions based on your observations. NO measurements will be taken on this day. a) Are the cut fragments showing signs of regeneration? b) How did you identify the regenerating portion?…

Q13: what is the correct answer

question: based on the graph, how could you best describe the relationship between the egg size (mass) and the number of eggs?  what would be a reason to observe the relationship between the two?  from what I have read about, there are several factors that can influence both the size and the number of eggs. also, its not just in butterflies where you can have larger eggs but less in quantity or smaller eggs and more in quantity. I'm trying to just figure out what a good reason for the observation would be based on the graph

plz answer and do explain.    1.) True or False: In animal phyla, endothermy is usually seen more than ectothermy? Explain why?

14. Nematode Life Cycle Matching: Match each of the descriptions below with the correct nematode worm species (A-D). Note that some descriptions may not apply to any of the 4 species (in which case just write “none") and some descriptions may apply to multiple worms species (in which case write the letters of all applicable species). (A) Dirofilaria (heartworms) (B) Dracunculus (Guinea worm) (C) Ascaris (D) Hookworms 1. Life cycle includes only a single host 2. The infective stage is a free-living larva that can enter the skin directly 3. On target to become the first parasite-caused human disease to be eradicated 4. Has an arthropod intermediate host 5. Traditional treatment involves winding the female worm around a matchstick 6. Infections can be prevented by not defecating on soill improving sanitation of soil 7. Female lays eggs around the anus of the host 8. Produce microfilaria that circulate in the blood 9. Has multiple larval stages and a snail intermediate host 10. Migrate…

Q17

Test II. Comparing Characteristics. Given the groupings of phyla, please indicate within the prescribe column whether these characteristics belongs to the group. Indicate your answer by writing Y if a characteristic and N if a non-characteristics. If the characteristic is not true to all members of the phylum, then write NY. Characteristics PORIFERA CNIDARIA PLATYHELMIN THES NEMATHELMIN THES MOLLUSCA bilateral symmetry sexual reproduction Characteristics ANNELIDA ARTHROPODA ECHINODERMATA CHORDATA bilateral symmetry sexual reproduction

Lab 10: Kingdom Animalia Introduction Animals all share some characteristics: 1) Multicellular 2) Heterotrophic 3) Their cells have no cell wall 4) At some time in their life they are motile. There are many phyla within the animal Kingdom, and in this activity, you will explore these phyla by building a dichotomous key that will allow you to consider almost any animal and determine which phylum it belongs to. Part 1: Organizing information for the dichotomous key 1) List the 9 animal phyla of macroscopic (visible) animals: Porifera, Cnidaria, Platyhelminthes, Nemotoda, Annelida, Arthropoda, Mollusca, Echinodermata, and Chordata. 2) Use on-line or library resources of your choice, to gather information about these 9 phyla. a. Start by finding two example species per phylum to help tie into your previous knowledge about animal types. Write down these examples. b. Make a list of characteristics that you could use that would help you tell these 9 phyla apart. The final goal is to build a…

STUDYING 6 Statistical exercise: Corals and Temperature Science often involves gathering data. The data may be counts or measurements or lists of species or may take many other forms; however, it is very common that biological data can be represented numerically. Raw data are often too repeti- tive and boring to be appreciated directly. They need to be sta- tistically summarized. The most ordinary way to get started on summarizing data is to enter them in a spreadsheet, such as Excel. Excel also allows one to graph data and do simple analyses. Today and in future labs, you will use Excel in these statistical exercise sections; today we will focus on how to cre- ate and use a spreadsheet. We will start with data gathered by Hollie Putnam, a stu- dent interested in understanding how water temperature af- fected the growth of coral. To determine this, Hollie took cor- als from their native habitat, where the average water tempera- 1 2 3 4 5 Create an Excel file with the data in the lab…
