Photosynthesis and Solar cells
In order for humans to live, as well as all living organisms, photosynthesis used by plants to create solar energy is essential. The way cells are created and regenerated is fascinating and we are still making new discoveries each and every day.
A solar cell converts light energy from the sun directly into electricity. Plant cells contains chloroplasts and absorbs light energy from the Sun. Plant growth and development are driven by continuous generation of new cells. (Inze, D. &DeVeylder, L. The plant cycle Annu.Rev Plant Biology, 54 235-236, 2006). There are several similarities in both cells. ATP in common in both plant cells and solar cells

2.1. Definition of Synthetic Biotechnology
To begin with, it is important to understand what does synthetic biology means. Synthetic biology derives from traditional biotechnology. Traditional biotechnology is defined as any technological application that uses systems living organisms or derivatives to make or modify products or processes for specific uses. This concept is linked to Genetic engineering which involves the manipulation of genetic composition by introducing or eliminating specific genes through molecular biology techniques and DNA recombination. In other words, Engineering Genetics allows

Introduction to Biology: SCI115
The article “Therapeutic Cloning, and stem cell Research” by Gena Smith is about how we can extract stem cells from replicated human embryos and use them for medical and therapeutic purposes. The stems cells are perfect because they are what the article calls “master cells” which with the help of science, can be manipulated to become anything from brain cells to kidney cells. The article also revolves around the amount of controversy over the issue of cloning. The article mostly reviews the medical side of cloning rather than the reproduction side which can one day

A New System for Cancer Detection
This article summarizes a new technique that would allow for cancer cell detection without being invasive to a person’s body. It states that currently, human cancer cell detection is conducted through a person being cut on or biopsied. This new procedure allows for humans bodily fluids to be utilized in detecting cancer cells. P.Chandra states, “While current cancer-diagnosis methods rely on an invasive biopsy” to relay that many may not feel the need or desire to undergo biopsy, a type of simplistic surgery, for cancer cell detection.

To feed on materials that are healthy for them, flies (order Diptera) use taste
receptors on their tarsi to find sugars to ingest. We examined the ability of blowflies to
taste monosaccharide and disaccharide sugars as well as saccharin. To do this, we attached
flies to the ends of sticks and lowered their feet into solutions with different concentrations
of these sugars. We counted a positive response when

Naturally, species go extinct. It’s part of life. Species generally are born and die within a million year time scale. That million year time scale is the natural rate of extinction. However, unknown to most people, the actual time scale at which species are disappearing from the planet is actually one hundred times higher than the natural rate. Obviously, this is alarming. Species should not be dying off this quickly. However, it is our own fault that the world is losing it’s diversity at an alarming rate.

The function of the respiratory system is to transport air into and out of the lungs and to facilitate the diffusion of oxygen into the blood stream, in order to carry it around the body and help remove carbon dioxide. The respiratory system is made up of tissues and organs in the body that enables us to breathe. It is divided into the upper and lower respiratory tracts.
The upper respiratory tract consists of firstly the mouth, nose and nasal cavity, its function is to warm, filter and moisten the incoming air. The pharynx is another part of the upper respiratory tract and here the throat divides into the trachea also known

One of the main difference between plant cells and animal cells is that plant cells have a cell wall, whereas animal cells don't. Instead of cell wall animal cells have cell membrane but the plant cells have both cell wall and cell membrane. The cell wall in plant cells work as a protection layer outside the cell membrane which also provides structure for the plant cell. It is seen as a shape giver to the plant.

The reasons you can get more proteins from the genes are because each gene is individual, and each protein has a different function. Some proteins are responsible for structural support while others are responsible for defense against germs; others are involved in bodily movement. There are 4 levels of protein structure. The first is primary, which is the sequence of amino acids that make up protein. Different proteins will have different sequences of amino acids. Secondary structures are the coils or folds in the helix due to hydrogen bonding. Tertiary structures are just further folding of the polypeptide and

Abstract/Summary: “Proteins account for more than 50% of the dry weight of most cells, and they are instrumental in almost everything organisms do” (Campbell, 1999). The significance of proteins to the continuation of our biological systems is undeniable, and a study of how to quantify proteins seems an appropriate introduction to our studies of biology. In order to study proteins we must first know how to separate then quantify the amount using basic principles of experimental design such as a standard curve. In this experiment we wish to quantify the amount of previously extracted protein by measuring the absorbance of the

Individual nucleotides of DNA are made up of three components:
A sugar called deoxyribose
A phosphate group
An organic base belonging to one of two different groups:
A single ring bases- cytosine and thymine
Double ring bases- adenine and guanine
The sugar, phosphate group and organic base are combined as a result of condensation reactions, to give a single nucleotide.
DNA is made up of two strands of nucleotides. Each of the two strands is extremely long, and they are joined together by hydrogen bonds formed between certain bases.

What makes one onion bigger than the other? Pondering this subject you could come up with a couple of different reasons why one would be bigger than the other. Knowing from prior observations that onions were composed of layers, the thickness of the layers may be an option, or the number of layers, or the shape, and the girth of the outside pealing might all be reasons for the difference in size. The reason I think that one onion is superior in size is that there must be more rings on the bigger onion

Mitosis and Meiosis at first seem much alike for that they both are forms of cellular reproduction. Moreover, they go through similar stages such as interphase, prophrase, metaphase, anaphase, telophase, and cytokenisis. However, despite their similarities, these two processes are much different and have their own specific importance in cell reproduction. Mitosis evolved because it is a process that occurs in somatic cells and allows the division of a cell into two genetically identical daughter cells that are called diploids (2n) and have the total amount of chromosomes. In mitosis, the only difference between an animal cell and a plant cell will be during the cytokenisis stage. In an

Temperature has a great effect on osmosis. Based on our data, the bags that contained water at 55 degrees Celsius had a much greater rate of osmosis than the bags at 15 degrees Celsius. When the environment is heated up, reactions occur at a much faster rate. This is because the extra heat provides more energy. Increasing the concentration also increases the rate of osmosis. This is because there is a lesser concentration of water inside the bag in the 40% rather than the 15%. The water will rush into the bag at a greater rate because of this. Our data shows that at both temperatures the bag that had 40% NaCl concentration added more water faster than the 15% concentration. Every

The Importance of Biology in the Study of Psychology
Ashley B. McVey
Whether it is the study of biopsychology and other fields of psychology or neuroscience, all psychologists and scientists are trying to understand the functions of the brain. The body and mind connection and how it reacts to certain behaviors or illnesses. Most all psychological functioning can be reduced to underlying brain processes. This should serve as reason alone as to why biology plays an important part in the study of psychology. Psychological factors play a role in whether a person develops a mental illness and in how well they recover from a mental illness, yet biological and
