5μg/ml cholesterol, 1mM MgSO4, 25mM KPO4 buffer pH6.0) which contained 0P50 E. coli, one week prior so that they would reproduce. Two different stages of development were found on the plate, adult, and larva, and 2-5 worms of each stage was collected in 2μl of diluted water. The adults C. elegans and larva C. elegans were put in their own centrifuge tube with 10μl RNA buffer (RB) and then spun for 5 seconds. Both tubes were intubated after at 65°C for 10 minutes and then at 85°C for 1 minutes.…

the autoinfection and reproduction within the host . larva found in the stool from intestine , adult worm free livening . The parasite male and female reproduction and produce fertilized embryonated egg , then the embryonated ova hatch to larva and develop to filarifom . The infective stage is the filarifom larva , the worm penetrate the skin to make infection and the filarifom enter the in the blood and transfer to lung then (alveoli…

ecosystem. What is a mealworm? A mealworm is a dark beetle larva. Mealworms have a head, thorax, and an abdomen. The mealworm has a spine but not the kind that we have. The mealworm is part of the invertebrate. The invertebrate family is a group of species that don’t exactly have a spine. The mealworm start off as an egg, then once they hatch, they turn into a larva. This is the stage that they look like worms. After living like a larva, they turn into a pupa. Then they turn into a dark…

When a larva hatches from the egg, it does not leave the bean to which its egg was glued. In fact, the larva does not even leave the egg and explore the surface of the bean; instead, without moving outside the protection of its egg, it burrows through the seed's outer layer and into its endosperm. The larva then spends its entire juvenile lifetime inside the bean on which its egg was deposited. Depending upon the temperature, humidity, and other factors, the larva, eats, molts and following…

I chose to investigate the environmental impact of gypsy moths because I have personally had experience cleaning up after these pests in northern Ohio and I know that they are becoming an issue in other parts of Ohio as well. I was able to witness some of the damage they have done while removing defoliated trees in Cuyahoga Valley National Park. Gypsy moths are a non-native, invasive species that, over the past decade, have been coming into the state from Pennsylvania and Michigan. The moth…

vial to provide more moisture. Next, three grains of yeast were added to each of the four vials. The vials were capped. Step 2. Observe adults First, to observe the adults, two capped glass vials containing culture medium and Drosophila from larva to adult stages were obtained. Each of the two vials was carefully observed one at a time for natural and mating behavior. The following mating behaviors were looked for during the observation: orienting, tapping, ‘singing’, licking, attempting…

The Drosophila melanogaster, also known as the fruit fly, was the primary research subject for Thomas Morgan. In 1910, Morgan used the fruit fly as an experiment to discover new mutations which could represent new species. Using the flies to research about heredity gave way to Gregor Mendel’s confirmation of his Chromosomal Theory of Inheritance which suggests that the chromosomes are the carriers of genetic information. The sex of the fly is important when culturing Drosophila and making…

from the intertidal zone to the deep sea. Barnacles in the intertidal region spend part of their day, during low tide, without seawater around them. Barnacles can also attach themselves to living things like whales, turtles, and manatees. Barnacle larva swim secrete a glue-like substance…

more of the fungi in each host mosquito. The hypothesis is that by genetically engineering the eggs and larva of the mosquito host to be of a significantly larger size, economically…

have a low chromosome number. The life cycle of Drosophila melanogaster begins with females laying eggs, then the eggs mature into three larval stages. The first stage is called the 1st instar larva, the second is 2nd instar larva, and the thirst is 3rd instar larva. On day eight, it is expected that the larva encases into pupa. Six days later, the fly encloses from the pupa. Finally, the flies mate ten hours after the enclosing…
