identify concepts on cells and to learn more about the functions and reproduction of cells within living organisms. Lab Summary: While doing this activity we experimented with bacterial growth and I was able to witness growth in its replication. Through the process of mitosis, I was able to view cellular reproduction. Lab Answers A. Bacterial growth observation. The population doubling time is estimated to be 20 minute. B. Cellular reproduction : The three types of cell separation are…

repairing or directing chemical processes. Ribosomes could be found around the cell or next to the endoplasmic reticulum. Cytoplasm is made up of cytosol. In prokaryotes all the cell content is within the cytoplasm whereas with eukaryotes the nucleus is separate from the cytoplasm. The cytoplasm is about 80% water and usually colorless (4). Eukaryotes only contains the following: Mitochondria are found in both plant and animals cells and are shaped like a rod. A mitochondrion contains outer and…

Preparation for Cell Lysis Obtain the mammalian expression vector for homo sapien ESR2 from Addgene. Assemble the vector to code for the proteins snail, slug and twist. Transfect HEK293 cells with the modified plasmids in petri dishes. Allow the cells to grow for 1-2 days so they will express the proteins. Transfer the culture medium to a centrifuge tube to separate it from the cells. Add 1mL of phosphate buffered saline (PBS) to the cells and swirl to mix. Separate the PBS from the cells and…

Cell aging and its mechanism has been a hot research topic. A large number of research results indicated that the aging degree of animals is inversely related to the mitochondrial function. The function of mitochondria is becoming weaker and weaker with the increase of aging degree [1-6]. Mitochondria generate ATP through the process of oxidative phosphorylation, simultaneously reactive oxygen species. Early researchs has proven that oxidative damage caused by reactive oxygen species is one of…

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…

The biological cell, as a metaphor for understanding disability, permits a dialect perspective of the body: as a construct socially negotiated between the natural and behavioural sciences. The "pathology" of disability is not located within the individual's body; rather, it is established as a "pathogenic" force of language characteristics of the cultural body. What can be found in the body of society is a system producing embodiments of engagement : social structures promoting the image of…

Macrophages are large phagocytic cells that are important members of the immune system and are created upon occurrence of damage or infection whilst microglial cells (also important members of the immune system) are resident cells and so act as a first response. Meanwhile, the microglial cells and macrophages from elsewhere migrate towards the site of the lesion at around 300micrommeters an hour. Once there is a…

of Mast Cells Mast cells is near the skin and organs and protects the human body from bacteria and viruses but can become over flammable or reproduce too fast, causing diseases that hurts your body more than helping it. But, this cell is one of the main protectors in the human body due to all the things it can do. This cell isn’t as well-known as others but is an important cell in the immune system. So what makes this cell so amazing? What is unique about this cell? How does this cell do…

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…
