Changes in altitude have a profound effect on the human body. The bodyattempts to maintain a state of homeostasis or balance to ensure the optimaloperating environment for its complex chemical systems. Any change from thishomeostasis is a change away from the optimal operating environment. The bodyattempts to correct this imbalance. One such imbalance is the […]

Each year a number of children are born with biological defects that impair normal function. For THREE of the following conditions, discuss such aspects as the biological cause, the methods of treatment and possible means of detection and/or prevention.One lethal disorder inherited as a recessive allele is Tay-Sachs disease. This is caused by a dysfunctional […]

hroughs in medicine are discovered. With these new developments serious ethical and moral questions arise. Advancements in genetic engineering, reproductive technologies, cloning, organ transplanting, and human experimentation are all causes of concern. The Human Genome Project, an incredible scientific undertaking determined to produce a map of the human DNA code, will tell us how each […]

Unit 1: Matter and Energy for Life1. Explain the cell theory. All living organisms are composed of one or more cells. Cells are the basic units of the structure and funtion of all organisms. All cells derive from pre-existing cells. In a multi-cellular organism, the activity of the entire organism depends on the total activity […]

In the middle of this century, bot biological and cultural anthropologyexperiences a major change in theory. In biological anthropology, biologicalanthropologists adopted an approach which focused on the gene. They saw thehuman evolution as the process of genetic adaptation to the environment. In themean time, there were also cultural analogies to evolution. Cultural evolutionalso followed a […]

Nurture Versus Nature The question of what is the greatest factor in the development of human intelligence, sociability, interpersonal skills, and personality has been debated as long as modern humanity has had the capacity to wonder about it. Depending on the intellectual background or mindset of any individual asked, the answer will vary. Some social […]

Someone once said that if you give someone an inch they would take a foot. Biotechnologist would like to receive an inch of allowance from the government to start the cloning process here in the United States. The fear, however, that cloning may become too advanced is a relevant response. Cloning is the copying of […]

The chapter takes the reader through an imaginative journey of medicine in the future. Although some of the possibilities proposed appear like material from a science fiction novel, they are based on emerging scientific breakthroughs. One of the themes discussed in the chapter is the increasing mastery of human beings to ‘play God’. Evolving new […]

Few recent scientific issues have stimulated so much media attention, public debate and government involvement as that of stem cell research. Stem cells offer people hope by promising to greatly extend the number and range of patients who could benefit from transplants, and to provide novel therapies to treat debilitating diseases such as diabetes, Parkinson’s, […]

Genetic Testing and Its Social Implications Probably, applied genetics most impacts on society are as a result of genetic tests. In general, genetic tests seek to detect some feature of a persons genetic constitution. This feature can be a disease causing mutation or a marker DNA sequence used to detect presence of another gene. Obviously […]

Fruit Fly Lab Introduction The major topic of this experiment was to examine two different crosses between Drosophila fruit flies and to determine how many flies of each phenotype were produced. Phenotype refers to an individual’s appearance, where as genotype refers to an individual’s genes. The basic law of genetics that was examined in this […]

You’ve just flown halfway across the world for an important business meeting, and upon your arrival, it’s already late. You check in to your hotel, but you’re restless from the flight and the time change. The sky outside is dark, though back home, it’s the middle of the day.Scientists in Japan want to help you […]

System’s development during the embryonic life The respiratory system begins to develop at the fourth week of gestation. It is necessary to point out here that the respiratory system consists of two main parts or regions. The upper respiratory tract, which is composed of the nose, nasal cavity and pharynx and the lower respiratory tract […]

Cell membrane is the focus of this laboratory experiment. The plasma membrane has got three components namely cholesterol, protein, and phospholipid (glycerol and charged phosphate). The molecules of phospholipid have got one water soluble end (hydrophilic) and the other end which is not soluble in water (hydrophobic). The hydrophilic head is composed of glycerol, negatively […]

Question1. Answers Root-Bernstein cites several evidences to his student to support the biological evidence of evolution. He starts with examination of homologies, the body parts that come from the same embryological parts but with different functions like a human’s hand and a bat’s wing or a whale’s flipper. He further gives the use of analogies […]

Developmental Biology is the study of a procedure whereby a single-cell segregates and selectively triggers expression of genes to generate compound organisms made of various cell groups. There are three major forms of substantiation that are acknowledged in all of experimental natural sciences when trying to understand a gene’s purpose (Gilbert, 2006). The first one […]

Biotechnology is a branch of biology which deals with the use of living matter in fields like technology, engineering and medicine. The use of the term in the modern world refers to tissue and cell culture and genetic engineering technologies (Kingiri, 2010). The concept however, comprises of a diverse variety and background of steps for […]

Introduction Life on earth depends on the sun’s energy. Not only does the sun provide warmth and light, it is also the source of energy for the process of photosynthesis that is the most crucial chemical reaction on Earth (Deatsman, 2006). All living organisms obtain the chemical energy through the process of respiration that take […]

Max Delbruk a leading physicist who alters converted to biology attempted to describe the transition. This was during the Connecticut Academy of Arts and sciences 1000th meeting. Delbruk observed that modern scientist acquainting themselves for the first time with biological issues is puzzled by the fact that there are no absolute phenomena. Most scientists get […]

CUESTIONARIO TECNICO DE LA MADERA 1) Cuales son los principales componentes que constituyen a la madera. La madera como toda sustancia viva, esta formada por multitud de pequenas unidades individuales cementadas entre si llamadas celulas. Las celulas de la madera son tubulares, de forma aproximadamente rectangular, su longitud no excede de unos 5 mm, y […]

The person- situational interaction discussed in the Isabella scenario can be effectively analyzed using the theory that states that people through the manipulation, evocation and selection process, get exposed to variant forms of problems they need to adapt to (Buss, 2009). Isabella faced adaptive situational problems caused by her desire to choose relevant friends and partners […]

These very recent beings who have gone through these evolutionary changes called were able to effectively ractice talking and enable themselves to engage into such conversation, sharing among themselves information and ideas. 2. Discuss the role of cooperation in the survival of our ancestors. Cooperation is one important virtue that enables the ancestors to survive […]
