The main objective of this lab was to observe the activity of enzyme peroxidase in real time under different experimental conditions. To see how peroxidase reacts with its substrate guaiacol under different conditions. We measure the amount of substances per test tube and then combine all of them together. Each test tube contains a measured amount of any listed substances including H₂O. Each measured amount of peroxidase along with its substrate guaiacol, and other listed substances will show how actively the enzyme oxidizes the substrate. To measure the…

Activity: DNA Packing Go to Concept 16.2 and study the Investigation: What is the Correct Model for DNA Replication? Note: The Meselson-Stahl experiment is one of those important experiments you should remember. Also, note how they use a centrifuge to separate heavy and light isotopes of nitrogen. Study screens 1-6, Click to Open the Lab Notebook and Questions and answer Questions 1-5, then submit your five answers for grading. Finally, back in the Chapter Guide Study Area under Chapter Review, take the Activities Quiz then submit it for grading by clicking Submit Answers for Grading. After studying this chapter you should know and understand the meaning of the following Word Roots: helic- = a spiral (helicase: an enzyme that untwists the double helix of DNA at the replication forks) liga- = bound or tied (DNA ligase: a linking enzyme for DNA replication) -phage = to eat (bacteriophages: viruses that infect bacteria) semi- = half…
Imagine you are an ecologist studying ecosystems. In this assignment, you are given three separate sets of data to study. *Note: You do not have to relate the information in the three sets of data to one another.…
5. Complete all five ecosystems and record your data in Table 1. The different ecosystems are…
Last term the Biology and Geography class went to Hastings Point, New South Wales to visit three ecosystems found in the area, such as- mangroves, sand dunes and rocky shores. Hasting Points is the smallest coastal settlement of Tweed Shire. The hamlet is nestled between the ocean on its east and a delicate estuary on its west. This report will focus on the unique coastal habitats of Hasting Points and the various issues that challenge the sustainability of mangroves surrounding Lot 156, this report also evaluates whether building a Mangrove Rehabilitation Program or EnviroHomes will be suitable for this area.…

a. Round 1 = white bead representing lichens. Our laboratory reading for the experiment stated that lichens are instrumental in the development and needs for all species. The text stated, “Lichens play a part in the creation of soils from which plants can obtain nutrients. Like all living organisms, lichens need nutrients and energy to grow. Nutrients may be obtained from the air including dust, water, and from the substrate organisms grows on obtaining energy through photosynthesis, which is the role of the algal partner. They may also be incidentally fertilized hybrid and insect dung” (Bottcher & Rex, 2012, p. 43). With the information obtained from the reading, without lichens, bees, trees, flowers, and humans will all have negative repercussions.…

With the evolution of animals living on land from animals living in the water, many changes needed to be made in order for survival. Each problem that these organisms may have experienced in the past has been dealt with a solution of some manner. One of the main problems was water storage. Because organisms in an aquatic environment are surrounded by water, they do no experience problems with water storage, but without an aquatic environment there are bound to be problems. The land organisms need to have water within their body that is able to be accessed when needed. A solution terrestrial organisms have developed is the loop of Henle in the kidneys. This is part of the nephron which makes a U-shape and is used to conserve and reabsorb water. Another solution to the problem of water loss is being nocturnal, which gives less water loss because of less heat. A second problem is gas exchange. Because oxygen is required, organisms needed to adapt to find a way to receive oxygen into their blood stream. Mammals do this through the alveoli’s moist membrane. This membrane allows for diffusion, and gas exchange is conducted across. The oxygen diffuses into the bloodstream while carbon dioxide diffuses out, and continues to exit the body. A third problem is reproduction. In an aquatic environment, male organisms released their sperm into the water which eventually ended up fertilizing a female organism. This is not possible on land because there is no way to travel easily through the environment. The solution to this was internal fertilization, where the male organism releases the sperm inside the female organism. The sperm would travel through the female (as the moist ideal environment) and eventually fertilize the egg. A last problem is temperature, where the heat is different from an aquatic environment. The heat in a terrestrial environment oscillates and drops unexpectedly. An adaptation made for this was the creation of endothermic organisms. Endotherms maintain a…

Salt marshes are a coastal ecosystem that is damp area of vegetation associated with shallow saline waters near the coast. The salt marsh I will be looking at is Keyhaven marshes which have formed behind Hurst Castle Spit in the Western Solent in southern Hampshire.…
Approximately 6.8 million people have disabilities which make it almost impossible to continue with daily life. They have had to give up what they use to be able to do, but now though the combining of the biological and the technological they don't have to. To understand combining the biological and the technological a person must first understand what it means.The definition of biological according to the Merriam-Webster dictionary is “of or relating to biology or to life and living things.” ,and technological is “of, relating to, or characterised by technology.” (Merriam-Webster). They work together to create many devices that help people with disabilities. Those devices are able to help people with brain injuries function at full capacity…
