Biology 9D 11 April 2015 10.1 Assessment 1a. Identify two reasons why a cell’s growth is limited. The larger a cell becomes‚ the more demands the cell places on its DNA. In addition‚ a large cell is less efficient in moving nutrients and waste material across the membrane. 1b. As a cell’s size increases‚ what happens to the ration of its surface area to its volume? As a cells size increases‚ the volume increases more than the surface area. However‚ the ratio decreases. Notice that the surface

The FGF is also involved in the development and maintenance of the nervous system [4]. Recent advances in isolating and maintaining stem cells have shown FGF2‚ and 5 are one of the key factors of proliferation and differentiation.

Cats vs. Humans At first glance‚ it might look as if there are very few similarities between a human skeleton and a cat skeleton‚ However‚ when you look a little deeper‚ you find many similarities in shape‚ structure and function. Evolution has shaped the cat as a hunter and predator. Everything about a cat has been formed to shape a leathal‚ agile fighting animal. In contrast‚ the skeletons of humans have formed to provide strength and stability. There are many similarities between the modern-day

mammals. Luckily‚ this continues throughout life‚ and is beneficial to college students in multiple ways! Similar to progenitor cells in the developing brain‚ the adult brain contains a small number of stem cells that are able to divide and produce neurons. Through research conducted involving slightly unpleasant treatment of rats‚ we can infer a lot about our own brains. Adult neurogenesis has been detected through a process of administering radioactive

Cord Blood Cells. Today medicine has reached great success in the treatment and prevention of many illnesses. Currently‚ scientists and doctors are paying more attention to technology of cells. Cord blood is the blood that remains in a newborn’s umbilical cord after birth. Cord blood‚ like bone marrow‚ is an invaluable source of a type of stem cell that can be used in a variety of medical treatments. New parents now have the option of taking an active role in treating future illness much like a
