Cellular Function
How do cells in a multicellular organism communicate with one another?
Cells communicate by chemical signals. Chemical signals are passed from one cell to another for example saccharomyces cerevisiae, the yeast of bread; wine identifies potential mates by chemical signaling.
Direct contact, cell to cell.
Through formation of connections or cellular junctions to neighboring cells.
By use of receptors whereby signaling molecules bind.
Forming groups' i.e. group together in a colony.
Communicate using light.
Through chemical and physical touch.
Through use of cell junctions, signal transduction pathways and cell to cell recognition.
Communicate with the aid of junctions holding cell firmly together.
Through production and receiving of chemicals and electric signals.
What are the usual physiological changes of aging and how are these differentiated from diseases?
According to Suzanna and Jennifer, (2006) these changes include; sensory changes, digestion, circulation and sexuality.
Diminishing sense of tastes, smell and touch.
Changes in bones and muscles leading to vulnerability to broken bones.
Lack of appetite.
Memory loss.
Change in hearing, decrease in sensitivity.
More wrinkles, more grey hair and stiffer arteries.
Changes in vision.
Stamina for physical work and less energy.
Changes in sexual desire and performance.
Loss of teeth to gum disease.
Under what condition are water excess (hyponatremia) and water deficit (hypernatremia) likely to occur, and what are the characteristics clinical findings?
Hyponatremia is associated with increased morbidity and mortality caused by renal water excretion as a result of low extracellular fluid volume or in appropriate secretion of ADH.it is characterized by low serum sodium concentration....
Cellular Function and Aging Tumor Suppression Protein 53 and Effects on Cellular Function and Aging The concept of aging has many intrinsic and extrinsic factors that act as markers on an individual organism. Ignoring mortality associated with external environmental factors, very few organisms can be said to have cellular immortality with no decrease in cellular function or repeat division in normal diploid cells. Cellular senescence is a normal process that halts
Cellular Telephones Pros and Cons The Research Project a separate project student, student researches a topic web produces a report-based research. Assignment: Each student choose topic, list an interest . Several students choose topic, work independent. Cellular Telephones The increasing high demand for communication has necessitated the invention of cellular telephones in the world. Advancements in technology have also played a critical part to see to it that communication technology serves the needs
Cellular protein synthesis is a two step process. The first process is DNA transcription in which inside the cell's nucleus a gene encoding protein is copied into RNA. Then genes, in the form of DNA, are branded into the cell's chromosomes. Essentially this transcription process is copying mechanism. The next step in cellular protein synthesis is RNA translation. This step occurs after the mRNA has been moved to the ribosomal
Function of Homeostasis in Human Biology The preservation of stability or constant condition in a biological system by means of automatic mechanisms that work against influences leaning towards disequilibria is Homeostasis. (Homeostasis {hohm-ee-oh-stay'-sis}) Homeostasis is the capacity of the body to preserve relative constancy and work even when severe changes occur in the external environment or in one part of the body. (Homeostasis: Toxiocology Tutor III) This is one of the
a&P Lab Design Project -- A&P Lab Ammonia (NH3) is produced by cells located throughout the body; most of the production occurring in the intestines, liver, and the kidney, where it is used to produce urea. Ammonia is particularly toxic to brain cells, and high levels of blood ammonia can also lead to organ failure. The imaginary organelle referred to as a hydrosome functions in a manner that decreases the blood
4G LTE Encryption When cellular phones first came out, the concerns about data loss and theft was not all that high. This was mostly because these devices functioned mostly (if not entirely) as phones with perhaps a camera phone here and there. Nowadays, however, cellular phones are often smartphones and they are literally small computers in terms of the data that they carry and the abilities that they have. Given that
