1. Identify the range of senses involved in communication • Sight (visual communication), Touch (tactile communication), Taste, Hearing (auditory communication), Smell (olfactory communication) 2. Identify the limited range of wavelengths and named parts of the electromagnetic spectrum detected by humans and compare this range with those of THREE other named vertebrates and TWO named invertebrates. Figure 1: the electromagnetic spectrum source: www.ces.fau.edu Vertebrates Human Japanese Dace Fish Rattlesnake Zebra Finch Part of electromagnetic spectrum detected ROYGBV (visible light) detected by light sensitive cells in the eye called rods and cones.
They are also covered in dense blubber. This blubber helps them stay warm in cold sea levels. There are two adaptations that these dolphins have made to help their need for energy. Dense
Many organisms use energy to perform their cellular functions. That energy comes from the energy that is stored in food then converted to adenosine triphosphate or ATP. ATP can be obtained with or without oxygen, aerobic respiration and anaerobic respiration. Aerobic respiration produces carbon dioxide (CO2) as a by-product while anaerobic respiration produces Ethanol (C2H6O) or Lactic acid (C3H6O3). In aerobic respiration the “CO2 produced during cellular respiration can combine with water to produce carbonic acid.”
In the short story, “The Rip”, author Robert Drewe uses the idea of Sophie holding a jellyfish “at arms length” to display how she is becoming wary of her father, John, and is keeping him distanced from herself. he reassures her, as if he was trying to reassure himself that their relationship will not become an “anecdote”, but a reality. John is thinking about how he wants to be freed from his emotional turmoil, and how badly he wants to spend this quality time with his daughter and protect her. This “protection” is symbolised by the shark attack (the divorce of John and his wife), and the fear running through everyones minds. This makes the reader feel as if John is putting pressure on himself to make Sophie like him.
In both cases, the organism is changing forms entirely instead of merely shrinking. We see butterflies so often we know every part of their life cycle and none of it is a mystery to us. On the other hand, we know very little about jellyfish and do not observe their life cycle on a daily basis. Because of this, it was ingenious for the author to include this comparison. I also really like the use of the word “metamorphosis”.
The lack of breaths per minute as the temperature is decreased indicates that goldfish are ectothermic organisms. Although other environmental factors may play a small role in the respiration rate of aquatic ectotherms, the experiment provided evidence that water temperature was greatly responsible. The biological significance of the experiment was that scientists may conclude that many other freshwater fish become inactive during the winter months due to the drop in water temperature. The results of the experiment may be applied to the real world by concluding that perhaps water temperature is responsible for why sport fishing in Louisiana occurs predominantly in the spring and summer months; the water is warmer and the fish require more food to maintain their respiration and metabolism. This experiment could have been adapted or modified to show that as respiration rate decreases, so does the fish’s metabolism
They are able to control their oxygen levels when diving and use echolocation making them successful hunters. Adaptations for Swimming On average killer whales can travel up to or more than 75 miles a day and sustain a speed of 8mph therefore they have to be well adapt for swimming. The pectoral fins are rounded and used to steer when swimming. They contain the same skeletal elements as land mammals forelimbs but slightly modified.
The bullfrog and the crayfish are similar and different in many different ways. To start off the crayfish is in the phylum arthropoda, they are invertebrates, and they can be classified as a cheliped which is a shellfish with one large claw and one tiny claw. Bullfrogs are in the phylum chordata and they are vertebrates. Both animals can be found in streams and ponds but bullfrogs can also be found in marshes but crayfish cannot. Bullfrogs reproduce externally which is when the egg is fertilized outside the female's body and then they drop off egg sacks full of tiny tadpoles.
Survival Behaviors of a Manatee... They have small eyes but they have a very good eyesight. The manatee has a strong a big tail to have speed in the water. Cannot live in cold waters, the water temperature has to be at least 68 degrees.
Like all crustaceans, lobsters molt their exoskeleton every year or two. They do this by splitting their carapace, the central section of their
Many scientists believe vision played an instrumental role during the Cambrian period and believe it to be the only thing that triggered the explosion. Before the Cambrian period, microorganisms could only sense light. With the development of eyes, predators could precisely target and catch their prey. For example, the five eyed Opabinia was a small critter that had five eyes making it very effective to target its prey. As a direct result of this ecological relationship between predator and prey, many soft bodies, organisms were forced to create difference defensive mechanism such as hard shells, scales, and spikes to cover the outside of the body as well as spinal cord and different swimming parts enabling them to swim rapidly away from predators.
I am going to tell you all about whale sharks’ adaptations. First, whale sharks diet is that they do not attack They do eat shrimp. Second, there habitat is in the warmer areas. Some have been spotted in the cooler warters. Last there habits they are solitary creatures.
The nostrils are closed when the great mammal is under water to prevent internal drowning. As well as this, the hollow hairs (guard hairs) acts as a wetsuit. The blubber (fatty layer) keeps the bear warm as it moves through the freezing cold water. Polar bears are strong and fast swimmers and can obtain a swimming speed of approximately 10 kilometers per hour. This is a useful adaptation that helps them speedily escape when hunted by
Marine organisms are animals, plants, and other living things that live in the ocean. A Marine biologist is a scientist who studies marine organisms and studies the bodies, behavior, and the history of marine organisms. They also study how marine organisms interact with each other and their environment. I have chosen to research about Marine biology because I would like to learn about sea life, the ocean, and its surrounding environment. To start off, a Marine biologist might study coral, crabs, fish, microscopic marine organisms, sea stars, seaweed, squid, or whales.
They are very unique in many different ways and a crucial support for human life. They play also a very important role in the marine life such as giving shelter and food for millions of species including fishes, crabs, or shrimps. They support 33% of marine fish species. They also have specific and certain conditions to be formed, and to survive. They are also known as the “rainforest of the oceans” because of its huge diversity.
