were at one point in evolution, prokaryotic cells. It is said that before they had the function and job that they have today, that the mitochondria and the chloroplasts lived on their own and commonly took shelter inside of larger host cells. There they provided the host cell with the nutrients that it needed to live, and in return the host cell gave the cells a protected place to live. Eventually the host cell, the mitochondria, and chloroplast cells became dependent on each other for survival.…

In Phillip K. Dick’s Do Androids Dream of Electric Sheep?, the character J.R. Isidore is what most people call a “chicken head.” The term “chicken head” was given to those who were mentally damaged by the radioactive dust that has covered their atmosphere. Even though J.R. has been mentally damaged, he is by far the most empathetic character in the novel. Most of the so-called “normal” humans think people like J.R. are less than human. J.R. goes as far as saying, “But what does it matter to me?…

Some cells are uncomplicated, but others are complex with internal structures called organelles. These cells can be put into two categories which are the prokaryotes and the eukaryotes, and they have many differences and similarities. The prokaryotes derive from prokaryotic cells whose fossils have been in existence for over 3.8 billion years, which mean they have learned to adjust to the earth’s environments more than any other life form. Prokaryotes are the bacteria and their close relatives,…

water enters the cell because it is hypotonic to its environment. As a result, they need to use contractile vacuoles to get rid of excess water in the cell, enabling it to osmoregulate. Compare the ideal osmotic environment for animal cells and plant cells The ideal osmotic environment for animal cells would be if it were isotonic, meaning the cell and the environment have the same concentration of solutes and water, so the cell won’t change. The ideal osmotic environment for plant cells would…

This film explains how all humans are created. There are around 365,000 new babies made around the world everyday. Our bodies natural instinct is to make babies. It is what we were made to do. Even when we aren't doing the"physical" part of it, our bodies are still creating eggs and sperm to get us ready to try to reproduce. Our bodies are made up of DNA. DNA is made up of chromosomes. We get 23 chromosomes from our dad and 23 chromosomes from our mom. We are made up of 46 chromosomes to make…

around today.Robert Hooke’s main 2 discoveries were the force of springs and microscopes. Hooke was an english philosopher, architect, and polymath. He discovered the cell walls using microscopes. His discoveries has really helped the world today and will continue to help the future. Body Paragraph 1: This paragraph will be about your Cell Biologist’s personal life, and life as a scientist. Robert Hooke was an english philosopher,architect, and polymath .He was born in england on July 28…

us produces the female egg cells necessary for reproduction, called the ova or oocytes. The reproductive system is very important part of the body system because it helps the population to reproduce, it is a very crucial factor of living.The reproductive system helps our body to produce new cells. One of the most widespread diseases of the reproductive system is known as prostate cancer that only affects the reproduction cells. Prostate cancer mostly happens when the cells in the prostate cancer…

blood cell or hair follicle to be examined.Example: suspected homicides,suicides,and cases referred from the court. 3.PCR application in the identification of genetic disorder: The Polymerase chain reaction technology has been most commonly used to amplify the gene segments which contain kenned mutations for diagnosis of inherited diseases like beta thalassemia, sickle-cell anemia,cystic fibrosis,etc. 4. PCR is especially useful for the prenatal diagnosis of inherited diseases where cells…

DISCUSSION OF THE CAUSES OF HUMAN SKIN COLOR VARIATIONS The variation of human skin color is a complex phenomenon which have not yet been researched and studied conclusively. However, various researchers and academicians have given insight about the possible causes of this important trait. Different researches using people from different parts of the world, evaluation of their environments and diet and to some extent DNA analysis have given a variety of possible causes of human skin color…

innate protein particles or aggregates.However, there is a mechanistic difference between the two aspects. In the case of a pure solubility issue, i.e. a protein becomes insoluble in a certain solution (no changes in protein structure and integrity) and a solid phase is formed, a strong dilution of the system may lead to the dissolution of the protein. In such a circumstance, the term “protein associates” may more appropriately describe the formed protein solid .In this instance, protein…
