Lets compare a living cell to a water balloon. When we fill the balloon up with excess water, it goes into a hydropic state meaning the overall size of the balloon expands as more water is added and the lining of the balloon becomes thinner. Well to avoid the balloon from breaking, we would simply let out the excess water. When it comes to the cell, there can either be reversible or irreversible injury. With reversible injury, it is only short term, and the cell will return to its natural size once the problem is resolved.…
1. Explain how cells specialize to form specific tissue and organs. Cells specialize to form specific tissue and organs by stem cells being able to develop into every type of cell in the body and eventually recreate a person’s tissues. With organs, after you gather the cells which can be from the patient’s own organs you have to go towards how they grow and specialise. The cells need to be put in the right environment, and exposed to the forces that they would normally experience in the body.…
And when solution density corresponds to the buoyant density, DNA reaches a more balanced state. 1b. The generation time refers to the length required for a single cell to split apart into two separate cells.…
Lab 4: Osmotic regulation of cell volume The eukaryotic organism requires homeostasis to maintain daily activities and life. Zooming into smaller units to make up an organism, cells also require homeostasis in order for the organisms to function. Understanding the different balance cells need to maintain will aid us in understanding how cells in organisms successfully maintain osmo-regulations. Eukaryotic cells have selective permeable membrane giving them the unique function of regulating specific molecules between the intracellular and extracellular environment.…
Stem Cell Assignment 1. Summary of “Your Inner Healers” New scientific discoveries have shown that adult mouse cells can be “rewound” to once again be pluripotent like they were in their former embryonic state by adding a mixture of genes to the cells (called induced Pluripotent Stem Cells, or iPSCs). This contradicts the natural progression of cells’ potency as they age: in their early formation, embryonic cells have the ability to mature into any one of the 220 types of human cells, and soon after that they begin to lose potency and are only multipotent — able to develop into just a few different types of cells, until finally they become terminally differentiated, and therefore unable to develop into any other types of cells.…
A town faces many signs before it dies, this doesn’t just happen overnight and this is the responsibility of everyone in the community to prevent the death of the town. Some of those signs include population growth. How can a community survive without people? A town flourishes due to families purchasing their needs and wants.…
How does the ratio of a cell’s surface area to volume place upward and downward limits on cell size? The ratio of a cell’s surface area to volume place upward and download limits on cell size. One instance is when the size of a cell becomes larger, volume increases more than surface area, therefore the ratio of surface area:volume becauses smaller. However, when the cell shrinks but the number of those same cells increase the opposite will occur.…
Worksheet 1 1. How would you explain the cell cycle to your patient? (20 points) Scenario: A 21-yearl-old lady came into the primary care network clinic to avail of health teachings and resources for first time mothers. After graduation from nursing school, Alisha Marston got married to her former classmate and now expecting a baby due in 7 months.…
Lethal Damage is irreversible, irreparable, and leads to cell death; Sublethal Damage can be repaired in hours unless additional sublethal damage is added and eventually leads to lethal damage; and Potentially Lethal Damage can be manipulated by repair when cells are allowed to remain in a non-dividing…
and there may be problems for those people. Certain things need to happen to be able to successfully hold new large populations in urban areas, there needs to be employment opportunities, there needs to be sufficient infrastructure that is built up to a certain standard, and there needs to be a transportation system that is adequate for any given amount of people.…
Although scientific research has come a long way since the beginning of time, it has not done so without some kind of controversy. From Biopsychiatry to the Tuskegee Experiments, it seems as though there cannot be any scientific breakthrough without some kind of ethical issue. Stem cells are another example of a controversial treatment that is taking the medical field by storm. Although it is very controversial, it’s results are truly amazing and beneficial to anyone who is willing to give it a try. Stem cells have the potential to divide into special cells through a process called “mitosis”.…
1. What is the difference between mitosis and meiosis? Define each term, and then explain how each process contributes differently to the conception and growth of a zygote. The two ways cell division can occur are through mitosis and meiosis.…
CANCER CELLS VERSE HEALTHY CELLS The cells in our body are always replicating through the process of cell division known as mitosis. The cells growth is regulated, meaning that cell division only occurs when cells are damaged, lost, or worn out. However, some cells such as cancer cells lose control of cell division and reproduce uncontrollably. They lose their control of replication when the gene, in which controls the cell to stop growing at a certain point, is lost or not present.…
Eukaryotic cells come in a variation of forms. Some can be single-celled organisms that are generally bigger than prokaryotes. Human adults are made up of about 100 trillion cells of over 200 distinctive types. Internally, eukaryotic cells are considerably more complex than prokaryotic cells. The prokaryotes as well as the eukaryotic cells are enclosed in a spoongy cell membrane, but unlike prokaryotes, eukaryotes also have membranes within the cell that enclose tiny intracellular compartments where essential functions and processes can occur in isolation from the rest of the cell.…
The term neoplasm refers to tumors that are masses or growths that arise from normal tissue. Can a growth occur at any time in life? Are all neoplasms life-threatening? Explain in your own words why or why not.…
