Australian Ectotherms and Endotherms- temperature regulation Part A :Types of Temperature regulation 1. Write down the meaning of the terms endotherm and ectotherm. Consult a textbook if necessary. a. endotherm Endotherms are animals that can maintain a constant internal body temperature. For instance mammals and birds are true endotherms that can maintain a constant internal body temperature b. ectotherm Ectotherms are animals that are not able to regulate their body temperature or in simple

Extended experimental investigation: effects on membranes of environmental stress Background It is not possible to observe membranes directly‚ so this investigation is an indirect study of the effects of different substances and treatments on living beetroot cells. Beetroot cells have been chosen for this activity because each beetroot cell has a large central vacuole bounded by a membrane (Figure 1). Contained in the vacuole is the red pigment anthocyanin‚ which gives the beetroot its

Lung Capacity I. Introduction. The chest contains two lungs‚ one lung on the right side of the chest‚ the other on the left side of the chest. Each lung is made up of sections called lobes. The lungs are soft and protected by the ribcage. The purpose of the lungs is to bring oxygen into the body and to remove carbon dioxide. Oxygen is a gas that provides us with energy‚ while carbon dioxide is a waste product or “exhaust” of the body. | To deliver oxygen to the body‚ air is breathed in through

Experiment 8.1 Yes there was a change because with the starting snail population there was a great variation from 1-7. After the crab began eating only the snails with the thickest shells survived. The snails with the thinnest shells were eaten by the crab. Only snails with shell thickness 4-7 were left after the crab had their meal. The original snails with thickness 1-3 were eliminated from the population by the crab. The crab will usually try to expend as little enrgy as it can to maximaize its

Genetic Traits Exercise: Introduction: The pioneer of modern day genetics was an Austrian Monk named Gregor Mendel‚ who established the basic laws of heredity from his studies with pea plants in the late 1800s. Mendel’s fundamental genetic principles may be applied to a variety of traits from many different organisms. Each genetic trait‚ such as flower color‚ is regulated by a pair of genes called alleles. These alleles are found at particular places on the chromosomes called loci. During meiosis

Much has been written in recent years about terrorist attacks and weapons of mass destruction. Explosives are the weapon of choice for many terrorists as reported by the media on a routine basis. The bombing of the Pan Am Flight 103 that occurred on December 21‚ 1988 over Lockerbie and Galloway was no different. This bombing became the largest criminal investigation that was led by the smallest police force. (CIA) The New York bound flight fell out of the sky being in the air less than 40 minutes
