Lab: Investigation of the Structure of Onion Cells Purpose: To investigate the structure of onion cells and become familiar with some of the basic parts of a cell. This lab will also introduce you to the technique of preparing a wet mount slide. Materials: microscope, pencil, cover slips, lens paper, paper towels, blank white paper,…

Reptiles are characterized by a unique combination of features that is not found in any other animals. The characteristics of reptiles are numerous and cannot be fully explained in detail in this report. These characteristics include being cold-blooded, having lungs, direct development without larval forms like amphibians, having dry skin with scales, an amniote egg,…

Understanding the identity of microorganisms is crucial for several purposes. These include identifying the causative agent of a disease in a patient, which is essential for determining the appropriate treatment. Additionally, knowing the correct microorganism is necessary for producing specific foods or antibiotics. In this study, I employed all the methods I had learned in…

Enzymes are biological accelerators. They are called accelerators because their chief occupation is to rush up and command reactions in the organic structure but they themselves remain unchanged at the terminal of the reactions. They change the rate of reactions so that it ‘s suited for our organic structure. Enzymes are ball-shaped proteins ; their…

This paper will examine and compare the ideas of absolute threshold and difference threshold. Absolute threshold is the lowest level of stimulus that our sensory receptors in organs like the eyes, ears, nose, and mouth can detect. These receptors are vital in detecting stimuli from the external environment and sending them to the brain for…

Fossils- fossils provide evidence of evolution because related organisms have similar but varied bone structures. Carbon dating and radioisotopes allow scientists to find when the rocks and fossils lived, allowing them to see how the organisms changed over time and adapted to new environments. * Embryology- many animals have an extremely similar embryological stage. Only…

This experiment is carried out to analyze the growing dynamicss of micro-organisms in shingle flask. E.coli is grown in a LB broth medium and being fermented for 24 hours. Throughout the agitation, the cell civilization is taken out for every 3 hours and protein trial, glucose trial and cell dry weight are being performed. As…

While the main emphasis is not always on the acquisition of exotic animals by individuals, there are cases where owners demonstrate risky behavior when dealing with their wild pets. These people frequently lack knowledge about the nature and capabilities of their animals, neglecting to take necessary precautions for their safety as well as that of…

Antibodies function as mediators of specific humoral immunity by engaging diverse molecular and cellular effector mechanisms that serve to eliminate the antigen. They are produced by B lymphocytes and plasma cells in the lymphoid organs and the bone marrow, but they perform their effector functions at sites distant from their production. Like the T cell…
