Rod cell

unit of life is the cell. All living things are composed of cells. Cells may only from through a process of division and replication of previously existing cells. Cells are microscopic; however their structure is complex. All types of cells possess a plasma membrane which separates its contents from its surroundings. . There are two types of cells: prokaryotic and eukaryotic. a. Prokaryotic cells are simpler than eukaryotic cells. Within prokaryotic cells are bacteria cells and archaea. All…

Genetically Modified Food Every human being requires food in order to stay alive. The food provides the body with the forces it needs to keep the heart beating, the limbs moving, and the lungs breathing. However, during the last century, scientists have been working in laboratories to create a new kind of food. This type of food is called genetically modified food. Genetically modified food comes from plants that have been altered in laboratories. This technology can be accomplished by moving…

Mendelian inheritance is centered around three laws discovered by Gregor Mendel. First is the law of segregation which states that during the formation of gamete the two allele pairs separate randomly. The second law is independent assortment which states during gamete formation each pair of the allele will segregate independently of the rest of the pairs of the chromosomes. The third law is the law of dominance which is that alleles can be dominant or recessive with the expression of the…

Many people use their phones to take cute family pictures or send a text message to ask someone where they are at. The generations have been changing the ways cell phones are being used. In Moalem’s essay, he states, “Until very recently, we’ve been thinking and speaking about the serious and long-term ramifications of bullying in predominately psychological terms” (Moalem 281). Many children and teenagers are…

In Ronald M. Green’s “Building a Baby From the Genes Up,” Green shares an anecdote, gives his support for genetic modification, addresses opposing arguments, refutes the opposing argument, and finishes with his support for genetic modification. His thesis is because genetic modification is already happening, we may as well embrace it and make it a part of our lives. In the other essay “Genetically Modified Humans? No Thanks” written by Richard Hayes, he addresses Green and his argument right off…

celled microscopic organisms with one strand of DNA. Their life includes consuming nutrients from their environment, growing, and then dividing into two cells. Bacteria are continuously growing and dividing. Bassler continues her discussion of bacteria by classifying humans as ninty to ninety nine percent bacteria. Humans have ten trillion bacteria cells in us or on us at any moment in time. Bacteria creates an invisible layer around our body that keeps harmful threats out so we can stay…

scientific process called the somatic cell nuclear transfer or SCNT. During this process, scientists remove the chromosomes from the egg cell and replace them with the nucleus of a somatic cell which contains two sets of chromosomes. Since the nucleus of the somatic cell comes from a human who already displays genetic variation from their mother and father, the clone will receive both of their sets of chromosomes from one cell, and not from both the egg and sperm cells (“What is Cloning?” 1).…

chanted Captain Xerox at headquarters, and with that our micro-V96 craft was propelled towards the cell membrane for the first leg of our journey to investigate the process of Protein Synthesis in a eukaryotic animal cell. The cell membrane is a delicate wall of phospholipid molecules, consisting of hydrophilic heads and hydrophobic tails that swayed and looked like a mosaic. Our craft could not enter the cell directly through the semi-permeable membrane as it consisted of a negatively charged…

Respiration Rate Analysis on Goldfish While Being Exposed to Varying Water Temperatures Avarie Wideman, Bronwyn Edgell, Brooke Farrell, Shannon Porter & Emma Milne 1 Uxbridge Secondary School, Uxbridge, Canada ________________________________________ Results After completing the goldfish respiration experiment we were left with an abundance of data that has lead us to these results. Through the experiment we have discovered that the goldfish's respiration is affected when exposed to extreme…

Peptidomimetics are compounds whose essential elements (pharmacophore) mimic a natural peptide or protein in 3D space and which retain the ability to interact with the biological target and produce the same biological effect. The demand for modified peptides with improved stability profiles and pharmacokinetic properties is driving extensive research effort in this field. Many structural modifications of peptides guided by rational design and molecular modeling have been established to develop…
