Introduction
Earthworms live in soil and get nutrients from eating the dirt and can eat ⅓ of its body weight, if they get too cold they will freeze and die.(Mrs. Harrison, 2017) When they are in the ground they go as far as 2 meters under and when they are getting cold they can go down further. (Journey North, Uknown time) This lab is important because it will help us understand how worms react to different temperatures of water. All earthworms live in the 2 to 3 inches of soil directly beneath the surface.(Unknown Author, Unknown time from http://animals.mom.me/effect-temperature-earthworm-population-6147.html) When temperature drops below 40 degrees, the worms will start to die off.

The cold water made the worm slow down while the warm water made it go faster. The cold water made worm 2 shrivel while the hot water made it elongate and made it jump away. The worms avoided the cold and warm puddles and not the room temperature puddle.
Conclusion
The data means that worms respond differently to the warm and cold water because the room temperature is what rain would feel like. My hypothesis was slightly correct/ supported because the worms freaked out from the warm and cold water but, the worm did not die from the cold water. Next time we could add ice water and scorch. In the end we figured out that worms hate all temperatures and are very sensitive towards all temperatures that aren’t like rain. This study was very important because it helps us understand part of the why on what we wonder about
First, 100 mL of regular deionized water was measured using a 100 mL graduated cylinder. This water was then poured into the styrofoam cup that will be used to gather the hot water later. The water level was then marked using a pen on the inside of the cup. The water was then dumped out, and the cup was dried. Next, 100 mL of regular deionized water was measured using a 100 mL graduated cylinder, and the fish tank thermometer was placed in the water. Once the temperature was stabilizing in the graduated cylinder, the marked styrofoam cup was filled to the mark with hot water. Quickly, the temperature of the regular water was recorded immediately before it was poured into the styrofoam cup. The regular/hot water was mixed for a couple seconds, and the fish tank thermometer was then submerged into the water. After approximately 30 seconds, the temperature of the mixture leveled out, and was recorded. This was repeated three
“The Tequila Worm” by Viola Canales is a marvelous book that shows the story of a young girl named sofia;on her journey to explore life but to never forget where she came from her roots which means becoming a good comadre.
The 2006 Pura Belpré Award was presented to Viola Canales for her coming-of-age tale, The Tequila Worm. Set in a Mexican American community in MacAllen, Texas, this story is told from the point-of-view of Sofia, a young girl who has many adventures in her small community. Through the course of the text Sofia develops from a young child who plays dress-up games with her cousins, to a young woman who is willing to move three hundred miles away from school.
An Investigation to Show the Effect of Temperature on Daphnia Plan: I will submerge some daphnia contained in a test tube in water of differing temperatures and measure their subsequent heart rates. Hypothesis I think that the heart rate of the daphnia will increase up until around 40ËšC at which point most of the daphnia's enzymes will have denatured and rate of metabolism will have stopped or decreased sufficiently to have stopped the daphnia's heart rate. Apparatus list Test tube Beaker Different temperatures of water Daphnia Pipette Stop clock Microscope Slide Safety Follow usual lab safety rules. There are no major safety considerations in this experiment as the daphnia aren't harmful and water above 40ËšC will not be used. Method To determine if temperature does have an effect on the daphnia, I intend to carry out the following experiment.
The simplest answer is that the antifreeze doesn’t allow the icefish’s blood to freeze in the cold temperature hence the name
The Meningeal Worm Infestation of up to 20 meningeal worms has been discovered in a single deer’s subdural cavity. The white tail deer are the preferred host, but they rarely ever suffer from any sick or neurological problems from this type of worm. We will see severe signs in llamas and alpacas; these are the two animals that can become infected with it frequently. The meningeal worm can cause damage to the central nervous system and could result in death, so it is important to try and catch it early and learn about how to prevent this deadly worm. Things that you should be familiar with about the meningeal worm are its life cycle, the signs in your animal, and any prevention or treatment options.
Oftentimes, people can recall at least one song they know that is undoubtedly catchy because of its repetitive nature. That song can become a nuisance, when it will not leave your mind. When a melody gets stuck in your head, sometimes it could take a whole day to forget the tune. A certain tune can be stuck in your brain for many years! In Oliver Sacks’ passage, “Brainworms, Sticky Music, and Catchy Tunes”, he talks about “earworms”, or a pathological repetition. Sacks uses patterns of development to inform the modern reader about the dark side of music.
The metabolic rate for the cricket and the cockroach will be different when physical stress and temperature changes are present.The null hypothesis is that the cricket’s metabolic rate will be similar to (Blaptica dubia) cockroach’s rate when physical stress and temperatures changes are present.
The protozoan commonly known as the “water bear” is an extremophile that has engaged many in the scientific community. The Tardigrade is an invertebrate that has eight legs and comes in many shapes and sizes. This group has many adaptations such as cryptobiosis that allows it to survive in extreme environments. The Tardigrade can be found from land, to water, to sulfur springs, and to over 25 species found in the frozen tundra of Antarctica (Miller et al, 2001). To understand these creatures this paper will summarize the taxonomy, reproduction, food, and protective genetics, of the Tardigrades. The first section to this paper will examine is how these creatures are divided taxonomically.
Flatworms belong to the phylum Platyhelminthes. They have the simplest body plan of all bilaterally symmetrical animals. They are called flatworms because their bodies are compressed. The mouth is the only opening into the digestive cavity the flatworms have. Food is taken in through this hole and wastes are discharged also through this hole. Flatworms have a well-defined nervous, muscular, excretory, and reproductive system. The flatworm distributes the food it digests through a digestive tube that branches throughout all of its body parts. The fact that the worm’s body is flat serves many purposes. It allows the worm to hid in small spaces, to fit into the opening of other animals if the worm is parasitic, and it means that all the cells are close enough to the surface for exchange of oxygen and carbon dioxide with the environment (Meinkoth 399).
This disease may be on the brink of being eradicated entirely but that doesn’t stop it from being one of the grossest things that anyone has ever seen. The parasite enters the body via unsafe drinking water. When people drink water infected with water fleas that have have been hosting the larvae of the parasite. There are no symptoms, to begin with, but about one year later, blisters on the feet or legs begin to develop and then the adult fully developed worm crawls out of the host body over a period of a few weeks. It’s said that the pain is intense and can incapacitate a person for weeks at a time. The pain can also continue for months after the infection. The parasite needs to infect a person at least once a year in order to continue. There were an estimated 3.5 million cases in 1986 but the disease has been greatly reduced over time and only 22 cases were reported in 2015. This disease will probably be the first parasitic disease to be completely eradicated in humans.
1. We hypothesize that the metabolic rate for the cricket and the cockroach will be different when the two animals experience physical stress and temperature changes.
Then, repeat steps 7-11 another 4 times but with the room temperature water. For the room temperature water just leave it in the room but try not to change the room’s temperature. 15. Try to put all your recorded data into a table for organization 16. Repeat the entire experiment for more reliable data.
My Experiences and “The Tequila Worm” In The novel The Tequila Worm by Viola Canales we see several Mexican traditions involved, and how the character reacts towards them. In the novel we see how the Mexican traditions take a big part in the life of a young girl. Also how being attached to her family not only changes her but the whole community around. I could honestly say that I still celebrate and enjoy some of the Mexican traditions Viola Canales talks about in The Tequila Worm.
The Arctic tundra’s extreme temperatures have caused species, specifically polar bears, to adapt to it. Polar bears feed on animals that live underwater; therefore, they are extremely strong swimmers. Their front paws propel them through the water, and their hind legs are used as rudders. Additionally, they have a thick layer of fat, keeping them warm in the chilly waters of the Arctic. This layer of fat maintains body temperature around 37oC through a process known as thermoregulation, so as to keep polar bears warm, even in the harshest weather.
