protein‚ grain starch‚ tassel weight and leaf angle score through decades of corn breeding. -Some traits are held constant while corn breeders are continuously changing their ideas of the ideal corn hybrid. Also‚ the corn breeders are doing what satisfies the farmers. Grain starch and leaf angle score has increased from decade to decade‚ while grain protein and tassel weight has declined. This makes sense considering cattle farmers have to supplement protein into the ration since corn has very little

Donesha Foster Lab Report Dr. Arrigo-Nelson Bio 120 - 1A Isopod Habitat Preference INTRODUCTION Isopods are found in different types of habitats‚ from freshwater or marine to deserts and in damp‚ cool areas. Pill bugs are slow-moving‚ crawling creatures‚ and they are cold-blooded‚ which means their body temperature is regulated by the surrounding environment (Grzimek). Like other invertebrates‚ pillbugs are ectothermic‚ meaning their body temperature varies with the environment (Pillbug Profile)

Part 1 Guided Experiment Identifying Your Organism: Hermit Crabs- Coenobita brerimanus Three features indicating that this is a living thing: 1. The hermit crabs crawl around in their aquarium 2. The hermit crabs eat their food 3. The hermit crabs respond to changes in their environment The Hypothesis: Hermit crabs prefer shade to sunlight Data Sheet: Hermit Crab Light Shade Behavior HC #1 X Immediately crawled back in to shade when placed in sunlight.

A Pill Bugs Preference to a Rough and Smooth Environment The experiment that I decided to look into‚ was finding out if an Armadillidium vulgar‚ also known as a pill bug‚ would have a preference to the two types of environments that I had decided to experiment with. The two types of habitats that I choose were saran wrap which is smooth and sandpaper that is rough. How I set up this test was I had a choice chamber with a barrier in the middle that had a little door cut out of the bottom center

Plants are cross-bred until they possess “desirable characteristics(12).” Crops such as “corn‚ maize‚ soya bean‚ and cotton(12)” have built a resistance to the herbicide “Roundup‚” which kills off weeds.

Introduction This experiment took place to observe Armadillium vulgare‚ better known as pill bugsand sow bugs. They are cannibalistic‚ being both the cleanup crew and their own children eaters‚ as well as eating decomposers. Pill bugs‚ formally called Isopods‚ aren’t actually bugs at all. They’re crustaceans with gills in their rear abdomen‚ with seven jointed legs on either side. When ill their blood will turn blue due to the amount of hemocyanin found in their regular blood cells‚ and when threatened

Balloons were then stretched onto the top of the bottles to catch any gas the yeast would produce to see if yeast is a heterotrophs or autotrophs. The bottle with the yeast and sugar produced much carbon dioxide because yeast eats the sugar to produce gas and make whatever the yeast is put in airier. When yeast eats sugar it produces a by-product which is alcohol. The bottle with corn syrup
