In one instance, the parent attacked a human who approached their babies. (fws.gov). The Northern Snakehead has made quite an economic impact on the areas it has invaded. Since it destroys ecosystems, money has to be spent on pesticides to attempt to wipe out the species. When the pesticide is placed in a pond, it kills every fish in that pond.
Biology Excursion Question Using data collected on field trip and two named animals, explain the relationship between the distribution and abundance of these two organisms and the abiotic features of the rock platform. There is a close relationship between the abundance and the distribution of organisms living amongst the long reef platform. Abiotic features such as temperature range, salinity, Ph. levels, turbidity, water availability effect the distribution and abundance of aquatic sea creatures living in the area. Some of the organisms such as Tesseropora Roseas (Barnacles) and Knobbly Winks have different adaptations, which allow them to survive in these harsh conditions.
Spill his blood!'.... At once the crowd surged after it, poured down the rock, leapt onto the beast, screamed, struck, bit, tore. There were no words, and no movements but the tearing of teeth and claws." (152-153). Evil starts to take over Jack, and he ends up killing one of the boys, Simon.
If the environment was hyperosmotic then an osmoregulator must intake water in order to survive (Campbell, 2008). When N. succinea are put into an environment not natural to their habitat, it can affect their cells in two ways which at extremes could cause the cells to shrink or swell up and burst. When a cell is placed in a hyperosmotic solution, it tends to shrivel up
They accomplish this by feeding on algae and bacteria. 8 Species of mussels are native to the river. The most prevalent are the eastern elliptio mussel and the eastern lamp-mussel. Mussels are eaten by a variety of birds, turtles, fish, muskrats and other mammals. Zebra Mussels are an invasive species that can cause harm to native species by attaching themselves to their shells preventing free movement and can even cut off their oxygen
The chromatophores allow the fish to rapidly change color by contracting and expanding the pigment in the chromatophores. The stripes are on the stomach of the fish and the dots are on the anal fin. The anal fin is on the back of the fish, and the fin provides them stability in the water. The Megladon has myomeres which run along the side of the body and are attached to the back bone. The myomeres can be used to identify specimens and help the fish move.
Plasma carries food from the stomach to cells but carries waste from the cells to the kidneys and intestine. The body needs lots of haemoglobin because it will combine with the gases; oxygen and carbon dioxide. The red cells carry the oxygen in the arteries and capillaries to cells of the body. One function of the blood is to transport materials within plasma and hemoglobin around the body. Plasma contains hormones, nutrients and waste substances.
Biology assignment by Haider Hamad The Digestive system Introduction The aim of this project is to find out the difference between human digestive system and animal. Human Digestive System What is the Digestive system? The human digestive system is a complex series of organs and glands that processes food. In order to use the food we eat, our body has to break the food down into smaller molecules that it can process; it also has to excrete waste.Most of the digestive organs (like the stomach and intestines) are tube-like and contain the food as it makes its way through the body. The digestive system is essentially a long, twisting tube that runs from the mouth to the anus, plus a few other organs (like the liver and pancreas) that produce or store digestive chemicals.
Ralph was upset because the fire had gone out. “There was lashings of blood,” said Jack, laughing and shuddering, you should have seen it!”(69) This quote is an example of how the boys were violent throughout the book, and became progressively more deranged. The boys hunted and killed a pig, when Jack explained that the head of the beast was to be a gift to the beast. “Jack spoke loudly. This head is for the beast.
Angel sharks have small, sharp teeth in trap-like jaws. They eat fish, crustaceans, and mollusks. All angel sharks capture their prey by ambush. Lying almost invisible beneath a layer of sand or silt, they wait until a hapless victim approaches before engulfing it with lightening speed, in its trap-like jaws. Their narrow pointed teeth are ideal for holding prey, most of which is swallowed whole.
