Biology Qs
Ca2+ ions have two fewer electrons, giving them a positive charge. They are most likely to form ionic bonds.
Suspension: heterogeneous, solute un-dissolved and will settle (examples: blood, cytoplasm). Colloidal: solute equally distributed but not entirely broken down (examples: insulin, gelatin). Solution: solute entirely dissolved/evenly dispersed in solvent (examples: urine, synovial fluid).
Surface tension, caused by polar attraction between the different molecules.
DNA loses its structure and therefore ability to replicate without phosphorous. It is also essential for energy storage (ATP/ADP) and bone growth and health.
One way to make such a division is based on the function of these molecules within the body; lipids, proteins, and carbohydrates are all ingested and generally used as fuel for the body, whereas nucleic acids perform a different function. Molecular structure could also be used: nucleic acids, proteins, and lipids are all chain molecules, carbohydrates are not.
6)
The membrane is fluid in that various substances can pass through it, so it is not solid, and a mosaic because it is composed of many different heterogeneous elemnts.
7)
The mitochondria -- without supplying energy, none of the other cell functions could be carried out.
8)
Diffusion refers to the tendency of molecules to spread out evenly amongst each other due to their kinetic energy. Osmosis is the balancing out of the concentration of two solutions -- usually in water -- through a membrane.
9)
They could also be acting as clotting agents in the event of a cut/tear, or possibly isolate an area of weakness or infection through clustering around it.
10)
A red blood cell needs to be this permeable to facilitate the transfer of nutrients. It works because the body's salinity and blood concentration in general is kept very consistent by other organs/mechanisms.
11)
Homeostasis refers to the natural tendency of the body to maintain certain vital characteristics (temperature, acidity, etc.). Allostasis refers to achieving the same balance, but is a response to a large change in the balance of one or more of these aspects rather than to the constant subtle changes of homeostasis. In this way, allostasis can be seen as a way of restoring homeostasis.
Biology and Social Construction Involved in Training Children It has been quite a continuing debate over the years upon whether biology and genetics play a more important role in the upbringing of children and adaptation of roles or whether social construction and nurture overrides the innate nature. As soon as the child is born and opens his or her eyes into the world, there is a need to determine the kind
Biology in the Real World Stem Cells Almost all life forms have stem cells in them and the main purpose of these cells is that through the process of mitosis they can divide into other various kinds of cells as well as into other stem cells. In animals there are 2 kinds of stem cells: Embryonic stem cells and Adult stem cells. The embryonic stem cells are the ones that are completely unattached from the
There are many different types of website that talk about biology; some of them include university websites which allows access to differing portals of biological information. Such websites as University of Michigan's "biology resource network" is an important source of information for all access to biology articles and databases from U. Of Michigan scholars and professors. Other websites include organization websites such as those of the American Society of
Biology/Philosophy The Humanities One can successfully argue that yes, the humanities are in fact a manifestation of biology. In doing so, of course, there is a fairly liberal definition of the term biology, as well as of what is meant by the humanities. Biology, in its most broad sense, is simply the evolution of life. That evolution includes the minute and microscopic processes that occur within the body, as well as the
Biology Experiments Sex protein is as essential part of the female reproductive system. Vitellogenin is a protein found in the liver of female chickens (hen) which impacts the production of estrogen. Vitellogenin enters the hen's circulatory system and is then moved to the ovaries, where it is then converted to the egg yolk protein lipovitellin and phosvitin. As an experimenter the protein in male and female chickens can be compared through
Biology of Behavior A Multipolar Neuron The Limbic System Behavior is the range of mannerisms and actions that an organism makes, and is seen in conjunction with the environment or themselves. Their environment includes the inanimate items in their physical world, and also the organisms and systems around them. Artificial entities and systems can also exhibit behaviors, as behavior is not strictly the domain of single, individual organisms. There is a strong relationship
