The Evolution of Ichthyosaurs- Large Aquatic Reptiles In the early 1800’s, a new discovery that left paleontologists in awe was the fossil finding of the immeasurable amount of species of reptiles, Ichthyosaurs. Greek for “fish lizards”, these fossils were found all over the world. Because these large aquatic reptiles migrated just as whales do today, paleontologists have had the amazing advantage of collecting fascinating bone fragments throughout the past 177 years. Ichthyosaurs swam the ocean
The Effect of Light Intensity on the Rate of Photosynthesis in an Aquatic Plant Introduction The input variable I will be investigating is light, as light is just one of the 4 factors required in the green-plant process of photosynthesis. Photosynthesis is the process by which green-plants use sunlight, carbon dioxide, water & chlorophyll to produce their own food source. This process is also affected by the temperature surrounding the plant (the species of plant we experimented with
Sea Lions: Nature's Playful Aquatic Land Mammals Introduction Sea lions may look like sea creatures, but they also behave like terrestrial animals. Unlike whales, mammals that spend their entire lives in water, sea lions inhabit both the water and land throughout their lives. This aquatic land animal prefers the water for food, fun, and safety; while preferring the land for socializing, territory, and procreation. Being mammals, they share many behaviors common to humans and other mammals
Savanna Theory Versus Aquatic Ape Theory of Human Evolution The evolution of man is constantly in question. While we are reasonably sure that modern humans and primates are both related to the same common ancestor, there is constant debate over what initially caused the two species to split into early hominids and apes. According to some, our longest and most popular theory on the division of man and ape is profoundly wrong. However, those same individuals usually offer an equally controversial
The name of my species is Hydrilla. The scientific name of this species is Esthwaite Waterweed. The classification is Alismatales because all plants that fall there is either aquatic or tropical. Hydrilla has really impacted our world. The Hydrilla plant may be "good" to goldfish, for the reason that they play with it, yet it can ruin anybody's life. It was brought from another country, but it really impacted people's lives and the ecosystems. Although Hydrilla was originally from warmer parts
questions of how we became the way we are. However, our understanding of human evolution is hindered when pseudoscientific ideas refuses to yield to legitimate theories. One such idea is the aquatic ape hypothesis (AAH) which attempts to explain a number of human adaptations with the single explanation of a semi-aquatic ancestor. Proponents use incorrect “facts” and logical fallacies such as straw men, appeals to authority, and false comparison in their arguments. The idea appears intuitive and is easily
How Acid Rain Affects the Aquatic Ecosystem Abstract This paper shows that acid rain is a reality. It is destroying our freshwater ecosystems and must be stopped in order to save them. If the problem is not fixed soon the aquatic ecosystems will be destroyed. Table of Contents 1. What is acid rain? 2. Acidification of Freshwater 3. Effects of Freshwater Acidification 4. Where is Affected the most? 5. What is being done to fix it? 6. Conclusion 7. References What is acid
ecosystems living just beneath the hull of your boat? Boat exhaust and small traces of gasoline and oil are emitted into the waters when motorized watercraft are running. Boats have been shown to affect water clarity and can be a source of algal growth in aquatic ecosystems. The toxins emitted from boats can add chemicals to the water. Certain amounts of the fuel that is in motors is discharged, unburned, and ends up in the water. Boats may also cause disturbances by creating turbulence and noise thus becoming
information on this new species they had to murder nine other whales, one ‘accidentally.’ This finding was a great feat for science because it is important to learn as much as we can about a species before they become extinct. The rate in which large aquatic mammals are reaching extinction has been rising. So although there is much to be found and much that has been found about not only the new species of the baleen whale, but also the other two species that have risen to the surface, it was not done
Measuring the Heart Rate of Daphnia Daphnia is the name of a group of small, aquatic crustaceans commonly called 'water flies'. Because their exoskeletons are clear it is possible to watch daphnia hearts without cutting them open. This also allows the changes in daphnia heart rate to be studied quite easily. Hypothesis I predict that a daphnia should have a heartbeat of 190 to 200 per minute. However this would also be dependent of the room temperature as daphnias
Aquatic Therapy: The Benefits of an Aquatic Environment Over the past several years aquatic therapy has increasingly made its presence in the field of physical therapy. This type of therapy, which was once regarded with some concerns, is now offering more certifications in an attempt to increase its credibility. This sudden step towards utilizing aquatic conditions is primarily due to the many benefits it offers to a wide spectrum of patients. Due to the water’s specialized properties, aquatic
general area. An community is a population located in a certain area living among different species. An ecosystem is a larger mass of a population, a community, and abiotic factors. Ecosystems can be aquatic or terrestrial. The earth's aquatic ecosystem makes up about 75% of the earth's surface. This aquatic environment is divided into marine and freshwater environments. The earth's earthly ecosystem is mainly made up of forests and deserts, which make up for 25% of the earth's surface. The role or function
General Purpose: To inform Specific purpose: The audience will know that the Dead Sea is devoid of all plant and aquatic life, why the sea is so salty and the health benefits. Thesis or central idea: The Dead Sea has a unique environment Main Points: a. The Dead Sea is one of the saltiest bodies of water anywhere b. The Dead Sea is devoid of all plant and aquatic life c. The Dead Sea area has become a major center for health research and treatment Introduction: You know why they
behaviour of woodlice in a wet or dry environment or a light or dark environment. I chose to investigate the behaviour of woodlice in a wet or dry environment. Woodlice belong to the biological class crustacea. Most of the animals in this class are aquatic, and though the terrestrial species can breathe with the aid of primitive ‘lungs’ they lack the features found in most other land-dwelling arthropods. They have no waterproof waxy cuticle on their exo-skeleton and are therefore more likely to
The aquatic ecosystem is a major part of every day life including human life. The abiotic and biotic conditions affect aquatic as well as human life; and it can allow it to flourish or have a substantial negative impact. The abiotic factors of the aquatic ecosystem are light, oxygen, soil and temperature. The abiotic factors determine whether it cause damages or thrives the aquatic ecosystem. Every species has a tolerance range that influences its health, speed of growth and reproduction system
for a long period of time is whether the anatomy for locomotion on land was developed in water for swimming purposes, or if it was adapted after the creatures became terrestrial. Recent findings of fossils indicate that the transformations of the aquatic creatures happened underwater in order to help them survive in the changing world. When looking for answers, they had to examine forearm, hip, wrist, finger, and other bones, as well as the lungs or gills of the early tetrapod fossils. This information
Waller , Lambeck , and Daly, composed of thirty-seven aquatic therapy studies with one thousand and seven participants, and picked seven of those studies and used McGill Pain Questionnaire, Oswestry Disability Index, the number of work days lost from low back pain, and subjective assessment scale for pain to measure the outcomes. The SIGN 50 and PEDro scale assessment forms were used to assess the methodological quality. The results showed that aquatic therapy has a beneficial effect on low back pain
the opportunity to interact with other children. Aquatic therapy can be a valuable addition for kids on the spectrum to develop their motor, cognitive, and social skills. This intervention provides the child a setting where they can relax and enjoy play. Occupational therapists are there to assist the children in their interventions but parents are also welcomed to enjoy this experience with their children. Many children have benefited from aquatic interventions but this practice is not as common
This is where the benefits of aquatic therapy come in. Aquatic therapy is a subcategory of physical therapy, where the exercise and rehabilitation takes place in the water. It can be used for many things, from obese people with knee pain to those that suffer from lower back pain. This type of therapy is important because it can alleviate some of the symptoms of chronic heart failure without having to rely on medication. Aquatic Therapy Background Information Aquatic therapy is beneficial because
