Earthworm and Bullfrog comparison 1/14/2018 Dissecting the Animal Kingdom pd 7 pg1 The organisms i will be comparing are the Earthworm and the Bullfrog, the Earthworm is part of the phylum Annelid and the Bullfrog is part of the Phylum Chordate. The earthworm is a invertebrate and the Bullfrog is a vertebrate. This means that the Earthworm does not have a skeletal structure in its body but a bullfrog does. A key characteristic of both the animals is that they have bilateral symmetry. This means that that you could basically split both of the animals in half and both sides would be the same because they are bilaterally symmetrical, both halves of the body are identical.
If the bug walks over to the dry side, as opposed to the wet side, where the bugs are known to be attracted to those conditions, then it will give us the possible theory that pillbugs are communal animals, swayed more by majority rather than their familiar habitat. We will repeat the experiment multiple times to see how many of the bugs can be swayed by the majority, starting with 1, and ending the experiment with 4. Independent Variable: Bugs placed in dry habitat (starting with 9, ending with 6) Dependent Variable: Bugs that move over to the majority's habitat (starting
Internally fertilized eggs are deposited in gelatinous mass. The large, yolky egg of terrestrial snails are deposited in moist environments, such as leaf litter, and a calcareous shell may encapsulate them. In marine gastropods, spiral cleavage results in free swimming trochophore larva that develops into another free swimming larva with foot, eyes, tentacles, and shell called a veliger larva. Sometimes, the trocophore is suppressed, and the veliger is primary larva. Torsion occurs during the veliger stage, followed by settling and metamorphosis to the
Rolly-polly Research Paper Terrestrial isopods are also known as sow bugs or pill bugs. Pill bugs are related to lobster, crabs, and shrimp. Pill bugs are found in moist areas like under rocks; also they are different from sow bugs. Pill bugs curl into a ball when they feel threatened, as to sow bugs when they feel threatened, they run away.Today, for my experiment, I will need some soaked and dried paper towels. Therefore, one paper towel will be soaked with baking soda, and the other towel will be left dried.
The hands were washed. Goggles were placed on the eyes for extra protection. A petri dish containing nine pill bugs were obtained and set aside for later use. Two water bottles’ ends were cut and taped to each other creating a miniature tunnel for the pill bugs to crawl in. 50 mL of tap water was obtained in a small beaker and then was slowly moved into the lid of the bottle using a funnel.
Even the title of this book is intriguing and apposite within the content of the book. The inception of this title came from the fact that the cuckoo travels while leaving behind a significant amount of its eggs in other bird’s nest. Ideally, it uses the ignorance of other birds so that it can survive. Cuckoos have various strategies for getting their egg into a host nest. Different species use different strategies based on host defensive strategies, but most of them specialize and lay eggs that closely resemble the eggs of their chosen host.
Meaning of name: The Horseshoe crab gets its name because their arc shaped exoskeleton has been compared to what a horse shoe looks like. Description on animal: Even with crab in the name, they aren’t related to crabs and lobsters so much. They are actually related to scorpions and spiders. The female Horseshoe Crab is about 18-19 inches from tail to head, and the males are about 14-15 inches. Group of species: Merostomata Where Found: In North America along the Atlantic and Gulf coasts from Maine to Mexico.
A knuckle changeup has no spin on it and it “falls off a table” and dies into the ground if somebody hits it. The third pitch most people learn is the screwball. A screwball drives into the handle of a right handed batter. This in turn makes the batter hit a soft grounder to the short stop or third base. In order to throw a screwball, one must put their index finger on the top of the seam of the C and when the hand gets next to the hip the pitcher has to “twist the doorknob.” The next pitch, and my favorite, is the curveball.
They are usually found in wet and heavily vegetated areas. Native species are primarily found in undisturbed areas, but some can tolerate cultivation and a few species persist in deserts. Earthworms can be defined as terrestrial invertebrates that belong to the Order Oligochaeta, Class Chaetopoda, Phylum Annelida. Their characteristic features are that they are externally segmented with a corresponding internal segmentation, and usually have setae on all segments. They are hermaphrodite, and produce cocoons containing eggs which hatch into immature worms, that are similar to the adults except in size and development of their genital organs.
Numerous common names, in English as well as local languages, have been used for these species in both the pest related field and the local aquarium trade. Table 1. Names used in referring Pomacea caniculata Common names Golden apple snail (GAS) the commonly used name in south-east Asia Apple snail a general term for all ampullariids, but sometimes used more restrictively for the pest species Mystery snail primarily in
Others are displayed at the American Museum of Natural History and in the Queensland Museum in Brisbane, Queensland. Instead of teeth, Dunkleosteus possessed two pairs of sharp bony plates which formed a beak-like structure. Dunkleosteus, together with most other placoderms, may have also been among the first vertebrates to internalize egg fertilization, as seen in some modern
The cause and source of the bubonic plague were fleas. Fleas were the carriers for the bubonic plague. On their own, fleas cannot travel vary far, but fleas can be transported on other animals, mainly mammals. During the thirteen hundreds, ships were really making some major advancements, allowing them to sail year round instead of during certain seasons or weather conditions. Some problems on the ship, though, were the rats.
Hopefully, by the end of this paper you should be familiar with the behaviour, appearance, and other traits of the Red Velvet Ant. The first, and possibly most bizarre, trait of the Red Velvet Ant is its appearance. However, before we talk about the Ant I must clarify one thing; the Red Velvet Ant is actually a type of wasp, and doesn’t have much in common with an ant except for looks(Velvet Ants-MDC.gov). The Red subspecies of the Velvet Ants is covered in an orange, red, or red-orange color of hair. The wingless females look like large, furry, ants and in size range from 0.73in-0.83in.
