Cell division

The Cell Membrane is one of the most important parts of the cell. If not for the cell membrane it would be extremely easy for things to invade the cell; this is because on of the cell membranes job is to control what come in and out of the cell (i.e. ions, viruses, etc). Also the cell membrane is what helps hold the cell and all of its organelles Endoplasmic Reticulum (AKA the ER), smooth and rough whats the difference? The smooth ER does not have any ribosomes while the rough ER is covered in…

chanted Captain Xerox at headquarters, and with that our micro-V96 craft was propelled towards the cell membrane for the first leg of our journey to investigate the process of Protein Synthesis in a eukaryotic animal cell. The cell membrane is a delicate wall of phospholipid molecules, consisting of hydrophilic heads and hydrophobic tails that swayed and looked like a mosaic. Our craft could not enter the cell directly through the semi-permeable membrane as it consisted of a negatively charged…

Respiration Rate Analysis on Goldfish While Being Exposed to Varying Water Temperatures Avarie Wideman, Bronwyn Edgell, Brooke Farrell, Shannon Porter & Emma Milne 1 Uxbridge Secondary School, Uxbridge, Canada ________________________________________ Results After completing the goldfish respiration experiment we were left with an abundance of data that has lead us to these results. Through the experiment we have discovered that the goldfish's respiration is affected when exposed to extreme…

Peptidomimetics are compounds whose essential elements (pharmacophore) mimic a natural peptide or protein in 3D space and which retain the ability to interact with the biological target and produce the same biological effect. The demand for modified peptides with improved stability profiles and pharmacokinetic properties is driving extensive research effort in this field. Many structural modifications of peptides guided by rational design and molecular modeling have been established to develop…

blood type system, because it hooks 45 different surface antigen on the surface of the red cells that are controlled by two closely linked genes on chromosome 1. The antiserum for blood sample was the outcome results of the research that was done on the rhesus monkeys which lead to the naming of the Rh system. (Oneil, 31-07-2015) The RH factor works in a certain way, when the antiserum agglutinate your red cells you are Rh positive (Rh+) and when it does not , you are Rh negative (Rh-).Although…

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…
