Investigate the maximum power output of a solar cell

I am planning to investigate the maximum power output of a solar cell (photovoltaic cell). As I will be using independent and dependent variables I will need to keep many conditions constant. The independent variables I could change are resistance of circuit, light intensity, colours of light and surface area of cell. My dependent variables… View Article

Joseph’s Story

Joseph’s story is a common one of an unsuspected massive heart attack. Even though Joseph had numerous existing factors that put him at risk of heart conditions he continued to live with no fear, or ambition to make changes. While playing ball with his son in the park, Joseph experienced his worst case scenario, a… View Article

Stem Cell Research

Introduction A look at the progressive societies today indicates that science is encumbered by moral and political considerations.  The world of science is yet to be democratized and viable ideas are being sent to the gallows to satiate conservative thinkers at the helm of leadership.  A glimpse at most of the useful vaccines that have… View Article

The prokaryote cell

Capsule – almost all prokaryotes have a polysaccharide layer outside of the cell wall polymer, also known as the capsule. A discrete polysaccharide layer is the true capsule, while a gelatinous matrix which engulfs the cells is the slime layer or the biofilm. This capsule is constituted by polysaccharides and only occasionally by amono acids… View Article

Embryonic Stem Cell Research is Morally and Medically Ethical

Introduction Issue ( Background)  Science and technology have opened many doors of progress in all areas of business.  On such area far exceeds mere business and industry and touches upon human life itself.  The medical community has reached a point where it can quite possibly create new and healthy cells and organs to replace those… View Article

Damage and Repair Mechanisms of Cells and Tissues

Observation of the cells is something that modern biology has given an advantage of. Irritation of the cell can give critical information about the cell cycle, the damage on the DNA and its repair mechanism, and what will happen to the cell. In turn, since the cell is the basic unit of tissues, understanding cell… View Article

Types Of Cells

Select two structures of bacterial cells and briefly describe them; what do they look like, what are they composed of? Then, explain how these two structures allow bacterial cells to survive as unicellular organisms.             Two structures of bacterial cells are the cytoplasmic membrane and the flagella. The cytoplasmic membrane is mainly composed of two… View Article

Plants And Animals

Similarities             There are several similarities between animal and plant cells.  Both have membranes that make compartments which isolate cell functions and processes.  Both cell membranes contain different parts that serve different functions.  Both plant and animal cells need energy to go about its daily functions.  And both species undergo cellular metabolism, which consists of… View Article

Eukaryotic and Prokaryotic Cells

1. Two similarities and two differences between eukaryotic cells and prokaryotic cells. There are a lot of similarities and differences between the two types of cells, the eukaryotic and prokaryotic cells. One of their most notable similarities is that both are enclosed within a structure called a plasma membrane. The plasma membranes of both eukaryotic… View Article

Position Supporting Stem Cell Research

Cells that can make a distinction into a variety of cell types are called stem cells and comprise embryonic stem (ES) cells and adult stem cells. Since ES cells can turn into a new organism or can differentiate into any tissue type, they are said to be “totipotent.” Adult stem cells, conversely, as they cannot… View Article

Stem Cell Research: Medical Advantages

Greatly debated, stem cell research is very controversial; especially embryonic stem cell research. Many debate over the ethics of the research versus the medical advantages. The medical advantages outweigh the ethical views. The mass of embryonic stem cells that are used come for in vitro fertilization (IVF) (Black). Those cells are disposed as medical waste—using… View Article

The Reproduction of Prokaryotic Cells

Prokaryotic cells or prokaryotes are a type of cells that lack membrane-bound organelles such as a cell nucleus which differentiate them from their eukaryotic counterpart. According to the book Biology by Neil Campbell and Jane Reece, in addition, instead of a chromosomal DNA, the prokaryotes genetic information is found inside plasmids, which are basically characterized… View Article

Cell Theory

In biology, cell theory is a scientific theory that describes the properties of cells, the basic unit of structure in every living thing. The initial development of the theory, during the mid-17th century, was made possible by advances in microscopy; the study of cells is called cell biology. Cell theory states that new cells are… View Article

Cell Organelle

In cell biology, an organelle (pron.: /ɔrɡəˈnɛl/) is a specialized subunit within a cell that has a specific function, and is usually separately enclosed within its own lipid bilayer. The name organelle comes from the idea that these structures are to cells what an organ is to the body (hence the name organelle, the suffix… View Article

Diffusion and Osmosis

Diffusion and osmosis are very important in biological process. Diffusion is the movement of molecules or ions from a region of their high concentration to a region of their low concentration. Osmosis is the diffusion of water molecules across a semipermeable membrane. To gain a better understanding of diffusion and osmosis, we examine multiple experiments… View Article
