Essays on Pea

There have been a lot of documented events wherein large scale multinational corporations have been successfully victimized by cyber security and information system attacks. It is surprising and frightening at the same time that even those corporations are being targeted despite the fact that they are the ones that are very much capable of setting up formidable information system defenses against malicious entities. In the case of Sony, one of the latest victims of cyber security breaches, their latest announcement suggests that they are investing $15 Million for a more formidable cyber security defense. Evidently, their previous budgets were ...

Introduction

XX century was characterized with the significant technological progress, which has improved the life of people. Numerous products and services became available, labor and domestic life became easier and more comfortable. However, waste problem is the other side of the technological progress. The solid, liquid and gas waste are formed, and thus land, natural water and air quality degrade. Therefore, in XXI century the research efforts are dedicated to development of methods for sustainable use of water, gas, and solid resources. Wastewater polluted with dye residuals originate from textile, leather and food industry. These industries produce goods that ...

Introduction

During prehistoric times, human beings recognized that specific physical characteristics of animals, plants, and people could be passed from one generation to the next. This basic knowledge of genetics was of great importance in agriculture and also in the domestication of animals such as cattle and dogs. However, significant understanding of genetics, inheritance and variation came with the work of an Austrian monk- Gregor Mendel. In 1860, Mendel studied heritable traits of pea plants. He found out that these traits were passed form the parents to the offspring. His experiments with the garden pea plants led to the discovery ...

In search of Middle East Cuisine:

Overview: The search for a Middle East Cuisine embarks with a highlight on the Middle Eastern culinary and hospitality culture. Hospitality is fundamental to Middle Eastern culture and many home cooks utilize long hours, at times days, making a remarkable array of dishes for family feasts. Grains form an important and versatile role in the diet, with dishes ranging from eggplant dip, to dukkah lamb cutlets with mint and pomegranate salad and roasted red pepper and walnut dip (Hirsch, 2011). Daily staples entail hummus (mashed chicken pea and bread) and Shwarma (grilled lamb), while lentils, vegetables and meats are ...

Part 1

A: In the pea plant, the purple color is the dominant one while the white color is the recessive color. The F1 offspring that had purple colored flowers were 445 while those that had white colored flowers were 437. This gives a phenotypic ratio of almost 1:1. To attain this ratio, a parent with white colored flower (pp) had to be crossed with a heterogeneous purple colored parent (Pp). This can be confirmed by crossing the two patents as shown in the Punette square below.

B: The pattern observed can be explained using the first law of inheritance also called the Law ...

1) Proto-Oncogenes and Tumor Suppressor Genes are two types of genes that ordinarily keep the cell cycle functioning as it should. Explain the roles of these two types of genes, and explain what can occur when these types of gene are not working properly. Provide at least two different examples of cancers associated with mutations of these types of genes.

The purpose of the proto-oncogenes under normal circumstances is to make sure that cells proliferate, in other words the oncogenes stimulate cell production. But when a normal, healthy ocogene cell becomes mutated or expresses at higher than normal levels it causes cancer. The first oncogenic virus was discovered in 1916 and called the Rous virus after the person who discovered it, Peyton Rous. Rous viruses represent a family of viruses called the retro viruses. Retro viruses contain a genetic material called ribonucleic acid (RNA).

There is always the possibility that RNA will be transcribed into DNA (deoxyribonucleic acid) by an enzyme of ...

Summary of article one The first article titled “An Overview of the Pituitary Gland: The Endocrine System's Master Gland’’ begins by restating the role pituitary gland. According to this article pituitary gland produces hormones which have effects on the various parts of the endocrine system. These include adrenal glands, thyroid glands, ovaries and testes. The author goes on to state that pituitary, which measures about one third of an inch is located at the base of the brain next to another important part of the brain called the hypothalamus. Both hypothalamus and pituitary gland functions overlap according to Reham. ...

Abstract

The objective of the current experiment is to describe how plants function and pass on the traits. Dark is dominant to wrinkled and Green is dominant to pale green. A statistical approach is used for goodness of fit between observed data and data that are predicted from a hypothesis. Null Hypothesis: The results of the experiment are in agreement with the Mendel’s Laws. Dark is dominant to wrinkled and Green is dominant to pale green. The chi square values that are greater than 3.841 are expected to occur less than 5 percent of the time due to random sampling ...

Analytical methods to evaluate seed dormancy in legumes

Abstract Legumes are known to have multiple health benefits. The seed coat in particular contains a number of bioactive compounds which possess antioxidant activity. Of great interest is the relationship between the chemical composition of the seed coat and its role in seed dormancy. Modern technological approaches are currently used to further identify these compounds and determine their role in seed development; these include NRIS FTIR, mass spectroscopy, electron microscopy and chromatography. The following review describes the constituents of the legume seed coat and their respective roles in dormancy and other stages of seed development. The review also highlights ...

Red blood cells take approximately 120 days to be produced. The process of its production is called erythropoiesis and the place of production is myeloid tissue. For the formation of red blood cells, the haemocytoblast must be present. The existence of Multi-CSF causes the haemocytoblast to progress into progenitor cells. The progenitor cells, on the other hand, will form other cells. This cell may also develop into proerythroblast when EPO is present. Proerythroblast forms basophilic erythroblast which will in turn develop into polychromatophilic erythroblast, followed by normoblast which develops into reticulocyte which eventually becomes erythrocyte. All these developments must ...

Research question

The experiment was used to investigate the intraspecific and interspecific competition of plants in the same family. The experiment was to show the competition between plants of the same species and plants of different species. The variables included temperatures, light and water. Intraspecific competition occurs between organisms of the same species and since they are likely to have similar resource requirements they are likely to compete for any limited supply. In interspecific this is a complex ecosystem with many different needs competing for resources such as food, space or light.

Hypothesis

Competition among plants involves a struggle for limited resources such as ...

No can deny that the Great Depression created traumatic times for all the people living in the United States. “I get hundreds of letters each day and practically every one carries the same story, hence I am positively convinced that conditions are extremely bad, not only in our section but throughout the entire country.” In 1932 the front page of The Pharos Tribune reported that “water was being turned off in homes of the poor, meaning that many people were not only starving, but thirsty too.” Across the whole continent there was joblessness and homelessness. The Farm Security Administration ...

When I was a kid one of my best friends had a very unusual mother. She was a really nice lady though when she was not acting strangely. She made great cookies and snacks for example, but still she was, let’s face it: weird. Sometimes she was weird in scary ways, too. Let’s call my friend ‘Pea Jay’ so he will remain anonymous. His dad traveled a lot for business. His mom did not like that very much because she liked to have people in the house all the time. Whenever his dad was out-of-town Pea Jay was allowed to have ...

Introduction

Like any other class of organisms, aphids have their own adaptation to feeding. This can be easily deduced from their high precision in determining host plants from non-host plants. In this class, the mouthparts of insects are adapted to the various feeding modes which range from chewing to sucking. In our case of study, aphids have mouth parts which are highly adapted to sucking from plant phloem.

Theory of the experiment

Aphids are insects that can be a nightmare to farmers since they can become a perennial pest highly reducing the returns of the farmer. They are sucking insects which pierce through the plants and ...

Summary

Bilal Haq, a scientist from the National Science Foundation Arlingtion, Virginia encountered foraminifera on his trip to Qingdao in China. Foraminifera are small creatures that grow shells on their bodies. Their shells are varied and very diverse, as if they are created by visionary artists. Haq thought the foraminifera would make beautiful pieces of art and should be put on display. Haq’s fellow colleague from China, Zheng, agreed and put things into action by involving local craft workers. It resulted in a park for foraminifera since the end of 2009 and already a million people have visited (Larkins, 2012).

It is ...

Discussion questions

Metric system has only seven basic units, while the US system has more than 300 basic units; thus, it is simpler. In addition, units in metric systems are multiples of 10, therefore, calculations is easier than in US system. Metric systems are universally applied, except in USA. Perimeter is measured by distance round a figure whose SI units are meters; therefore, the perimeter is given in units of length. However, area is a derived quantity and its magnitude is obtained by multiplication of two units of length. Therefore, its units are given by the product of the units. Theoretical ...

Mendel’s Inheritance Patterns

Mendel’s approach in explaining genetic inheritance was different from the common genetic knowledge then, in that he explained that each trait was as a result of a pair of genes commonly referred to as alleles (O’Neil, 2011). The accepted knowledge back then was then traits (phenotypes) in living things were a blend from the parents. However, the Mendel’s approach contradicted with this notion arguing that there could never be a blend of traits in an offspring but existence of phenotypes being as either recessive or dominant. “An individual is said to be heterozygous when two alleles differ and homozygous when ...
