Reproduction Course Works Samples For Students

Information transfer is a communication and passage of a recorded message from one recipient to another. It contrasts a communication process where the sender and the receiver are contemporaries and requires that the transmitted message be in form of ideas. The transfer of information in a system should meet the needs of the user. As depicted in figure 1 a person with an idea represents that information in a medium. The medium for recording the idea fits in the model and the information is stored in an information system. The recorded information is stored in a different type of information system represented by a circle to contrast ...

Criticism involves the utilization of standards in order to make a judgment for the purpose of bringing positive change. Critical theory argues that we should be inquisitive about the production of enlightenment its dissemination and its connection to influence and how this impacts on the individuals; how it limits and contributes to the enhancement of our freedoms (Art 2011). Are we bound to a dominating freedom system or does it offer us a liberating system of government? The theory originates from the Frankfurt school in Germany.

Critical theorists begin with the thought that men and women are essentially enclosed in a world that ...

Write a 200 to 300 word response explaining how the physiological process of reproduction differs among the following organisms: Bacteria, Grasshopper, Fish, and Bear.

Among the four groups given, bacteria are the only animals that are capable of reproducing either asexually or sexually (Mader, 2004). This means that the reproduction process can either involve two parents or one parent. When bacteria reproduce asexually they produce offspring identical to the parent in a process called binary fission. The parent bacterium splits into two daughter cells. In sexual reproduction, the offspring is a product of two bacteria (Mader, 2004).

In the case of grasshoppers, ...

Corridors and Population Dispersion

Part I. Introduction and Review of Relevant Biology

1. Energy transfer becomes inefficient in higher trophic levels in a food chain. Predators utilize more energy in obtaining food than their prey. The number of organisms and the amount of biomass defines energy relationships among organisms in trophic levels. Most top predators are huge in size but their population is lower because there is not enough energy to support a large population of these predators (Odum and Barrett).

2. A population of infinite size is seen less likely to evolve since it would be almost resistant to random fluctuations within the environment. Small populations on the other hand are prone ...

Inter Office Memo

Background:
Our quality assurance department informed about the elementary toys that did not pass the quality test due to small quantity of lead in the toys. These toys are produced to be supplied to the elementary schools and will be used by young children. The quantity of lead identified in the toys is slightly above than the legal standards set under the USA laws. According to Consumer Product Safety Commission, the acceptable quantity of lead in children products is maximum 100 parts per million (ppm)(US:CPSC , 2011). Our company has already scheduled a large shipment of elementary toys that ...

Meiosis refers to the form of cellular reproduction where the division of cells results into the chromosome number being reduced by half and results in haploid cells. Mitosis, on the other hand, is the process through which cells divide producing daughter cells, which are diploid, and a replica of the parent cell (Department of Genetics, 2004).

Meiosis usually takes place in the sexual reproduction processes while mitosis takes place in asexual and cellular reproduction as well as in the general growth and body repair. Meiosis usually takes place in humans, plants, animals, and fungi and mitosis take place in all ...

- Graphs are a way to convey information and trends in a convenient fashion. For this week's Discussion Board you should search the internet for a graph related to biology. Provide us with a link to the graph, describe the variables, and interpret the meaning of the graph. I recommend that you choose a graph that concerns a biological subject that you find interesting.

This graph is about the growth curve of bacteria. In the x-axis, the variable is time, and in the Y-axis, the variable is the given number of microbes. As time progresses, bacterial growth undergoes various phases: These entail the lag ...

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 ...

Meiosis and mitosis

Gene transfer occurs during cell division from mother cells to daughter cells. The DNA carries the genetic information transfer which it from one cell to another during cell division. Genes are located on the DNA strand that is contained in a chromosome. Mitosis and meiosis are the two types of cell division that occur during reproduction in various organisms. Mitosis involves the nucleus dividing into two identical daughter cells. Mitosis goes in hand with cytokinesis, which result in two separate daughter cells at the end of division. The process of mitosis takes place in four phases namely the prophase, metaphase, ...

Cloning As an Application of Biotechnology

According to Levine (2009), Cloning can be defined as the reproduction without sex. The basic definition of sex in this context is the joining of genetic material from two parents to form an embryo. Cloning, however, does not use the technique of directly joining the female and male gamete, but it uses the fact that DNA can be duplicated by inserting DNA into a host cell (Levine, 2009).

During cloning, a fragment of DNA extracted from a cell and containing the gene to be cloned into a vector (Brown, 2010). The vector in this case acts as a vehicle that is going to be ...

Substance abuse is one of the key factors having a negative impact on pregnancy outcomes. The illicit drug use in women of reproductive age increases year by year in many countries, and the use of drugs, along with misuse of prescriptive drugs such as antidepressants and pain killers during pregnancy is common. Nicotine and alcohol which are the major risk factors for the fetal development itself are often used in combination with other drugs. Many women under special treatment report “polydrug usage” (Whittaker, 2003), a substance abuse can be accompanied by poverty, psychological distress and victimization. According to study by ...

Chapter 4: Prokaryotic Cells and microorganisms

This chapter looks at the morphology, and pathogenic mechanisms of prokaryotic cells and microorganisms respectively. It discusses in detail the structural components, functions of the different organelles of prokaryotic cells as well as feeding and survival mechanisms of prokaryotic microorganisms.

Prokaryotic cells have a specialized cellular structure. Prokaryotes are unicellular and their cells have no cellular organelles, that is, a membrane does not surround their nucleus. These cells contain intricate phospholipids, sterols, and sphingolipids. They are typically 1-5µm in diameter .

Their outer surface is covered by glycocalyx, which is a gel like cellular envelope that provides prokaryotic cells with protection against ...

I have read so much about the struggle of the idea with form that at one point, I simply could not restrain myself. Why is there such vitality in this topic? It is appropriate to recall Socrates with his definition of concepts and Parmenides with his opinions, but the most basic - look at ourselves, what we like is not the essence of which lies in the form of an idea? What is more important? Why? For what? For whom? What for? At different times philosophers have tried to define the essence of art, to understand what it is. ...

8)Using Marxist categories, fully explain the problem of the transformation of values into prices of production, mention the role of capitalist competition and the organic composition of capital in explaining the deviation of values from prices of production.

Marxist theory of transformation of values into prices of production is generally the view that labor is the inherent amount of value. Marx explains that a determination of prices by quantitative methods compatibly fits with the theory of labor considered as imminent amount or measure of value. This is a factual view that it is about the nature of exchange value and ...

Before taking this course on anatomy and physiology, I used to know that Aging has a significant effect on the reproductive systems especially the effects of aging on fertility. However, I did not understand all the hormonal changes involved in the decline of fertility due to age in men and women. After taking this course on Reproduction, I now comprehend all the changes in reproductive systems with age in men and women. For women the most significant changes occur at menopause while changes in the male reproductive system occur gradually over a long period. The sexual functions and fertility decline with ...

Abstract

The Darwin’s theory of natural selection best explains how some of the existing species have evolved over the years to what they are today. Natural selection entails a number of factors that affect genes, both in a positive way or negative way, causing changes that lead to the existing structure. This paper has given examples, or rather evidence of the Darwin’s theory, which has been received with both appreciation as well as critics.

Introduction

Natural selection is the mechanism that species use to evolve and possess genetic adaptations to the environment. The process is known as evolution. Many theories have ...

Nowadays the problem of poverty and limited resources becomes more and more urgent. The famous Hardin’s essay, “Lifeboat ethics” covers different aspects of this issue and gives strong but often disputable arguments against helping the poor in the worldwide, international sense. The fact that Earth’s resources are limited is undisputable, and Hardin’s metaphor comparing nations of people to lifeboats floating in the limited space of resources seems very neat. In this situation different ethical and moral problems come into play. The main ethical issue in current situation is helping the poor with the limited helping capacity and ...
