Mitosis and Meiosis Cell Division Lab Part 1-MITOSIS summary: In this experiment first the stages of an onion cell undergoing mitosis are going to be observed and every stage is going to be detected and drawn on paper. A brief description to what is going on should be attached to the pictures. This is important to understand the basics of cell division which is necessary […]

The term “wetlands” is often associated with the image of the coastal marsh – a muddy area that is teeming with a variety of animal life and emergent vegetation such as mangroves, rush and cord-grass. But wetlands are actually areas that are characterized by the formation of hydric soils and the existence of flora and fauna due to the presence of standing water during all […]

Abstraction The intent of this probe is to find the frequence of meiotic divisions analyzed from intercrossed crossings collected from different strains of the fungus Sordaria fimicola. The experiment was conducted to show intercrossed crossings with MI and MII forms of ascospores within the asci. Over the class of seven yearss, the sample of Sordaria was incubated and fused under research lab conditions. In the […]

ANTIMICROBIAL ACTIVITY OF CHILI (CAPSICUM ANNUM) EXTRACT An Investigatory Research Presented to Mrs. Presented by CHAPTER I INTRODUCTION Background of the Study . Capsicum annuum is a domesticated species of the plant genus Capsicum native to southern North America and northern South America. Chili has been a part of the human diet in the Americas since at least 7500 BC. There is archaeological evidence at […]

Lab Report #1 Introduction A cell’s plasma membrane is known to be selectively permeable. This implies that the membrane is selective on what substances can pass in and out of the cell. There are two methods of transport that occur through the plasma membrane. One method of transport is called active process which uses ATP energy to transport substances through the membrane. The other method […]

This causes a decrease in lung pressure, (intrapulmonary pressure) which establishes the pressure gradient from the atmosphere (1 59 meg) to the alveoli (105 meg) which then results INSPIRATION. As oxygen is inhaled it enters the external mares (nostrils), from the external mares it moves into the nasal cavity which functions in moistening, filtering and warming of the air. After the nasal cavity the air […]

Biology Investigation Aim: to investigate the effects of light and gravity on the growth of sunflower seeds. Background Info: Tropism is directional movement in response to a directional stimulus eg light or gravity. Plants are not able to relocate if they happen to start growing where conditions are nor perfect but they can alter their growth towards more favorable conditions. Plants respond to light (phototropism) […]

The Excretory System •Main functions of the excretory system are: oto concentrate wastes and expel them from the body oto regulate fluids and water within the body •Most metabolic wastes and toxins are dissolved in the body’s internal environment, so the maintenance of the body fluids is essential for keeping the body free of waste products enabling it to function properly. Excretion in Invertebrates and […]

Biology of Animals Dermatomes develop anus from plasterer Promotes develop mouth from plasterer. Presentation: Overview of Prokaryote, Protests, and Fungi l. Prokaryote (ex. Bacteria) Characteristics -unicellular -Small (0. 5-mum) salt. Pedagogical, Gram stain, virulence. Gram positive bacteria take up the Gram stain and turn purple, Pedagogical traps crystal violet, very thick cell wall made up of sugars. Gram negative bacteria crystal violet is easily rinsed […]

To investigate the effect of skin sensitivity In response to cold temperature in different parts of the body by timing the maximum amount of time in which Ice-pack can be held to that area. Hypothesis: If the layer of skin Is relatively thin, the nerve response to cold will be the fastest, Increasing the skin’s sensitivity. This therefore means that the fastest responses to cold […]
