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 of person they are going to be, the way they will deal with things and the relationships they will have with people. Human beings are the most social of all animals and are on a constant need to indulge with people around them. It is however recognized that each and every individual out there is different by nature, beliefs, values, morals and much more.
Sociologists and scientists have had a long obsession with trying to determine the extent to which the….
Biology in the eal World
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 blastocyst's inner cell mass and these cells are of great importance for a developing embryo and these are known as the pluripotent cells but these cells also play a great role in the normal return of the regenerative organs like blood, intestinal tissues and skin. Whereas, when it comes to the adult organisms these stem cells work as the replenishment system for the body as it refreshes the adult tissues and for this reason they are said to have a….

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 Environmental Biology, and other such organizations which uses the internet as a portal to all of their actual article information. Finally, there are websites that are specifically targeted for causes within biology, such as websites targeting stem cell research.
There are many different opportunities to find the right information within biology, it is necessary to siphon through a lot of different information. Understanding where to find accurate information is the hardest part of any research.

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 overarching or outlying processes that take place outside of the body. The humanities, in turn, are some of the most demonstrable facets of that maturation of the process of life, as are most other salient facets of culture (which is what the humanities are markers or indicators of).
In fact, when one considers the very nature of the name humanities, one sees the correlation between it and the word human. Humans and humanity evolved as facets of biology. Actually, humans evolved….
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 the process of electrophoresis. This process will allow the experimenter to look at protein from these two specimens and identify the vitellogenin, lipovitellin and phosvitin. There are pre-stained cells that can be purchased and it only needs to be viewed under a microscope for observations.
Hypothesis: There is a difference between male and female chicken protein structure.
Another research idea is to look at enzymes catalysis and determine which enzyme has a rapid time of completion. A rapid time of completion….
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 between behavior in biology, in two ways. There are biological components to the physical world that create expected behaviors in organisms, and there are also genetic and biological components that belong to each specific organism and that are used by those organisms to make sense of their world and to react to it in ways that provide them with what they need and help protect them from harm (Flint, Greenspan, & Kendler, 2010). Behaviors are not always successful in these….

There are about 6 billion nucleotide letters of a particular sequence in a human cell. The full set is known as the genome. DNA information is found in units called genes. One gene codes roughly for one protein. The proteins perform most of the functions of the body at the cellular level. Examples are digestion, the body's defense against disease, and transporting substances throughout the body. Thousands of proteins are needed to do the work of a single cell and of proteins within the multi-cellular human body. The proteins are coded in the DNA by these genes (Ridley).
Ribonucleic acid or RNA molecule is a single-strand structure, consisting of ribonucleotides (Tutor Vista 2008). It contains the pyrimidine uracil while DNA contains thymine. It has three types, according to cellular composition (Tutor Vista).

(01) Biomes and Diversity - Extinction is a natural selection process. hould humans strive to preserve a representative sample of all biomes or aquatic zones? Why should humans be concerned with the extinction rate?
Disregard for the conservation of the earth's biomes is an example of how human ignorance and hubris can result in irreversible environmental destruction. At any particular point in time, human beings cannot be certain that they know all they will ever need to know about the environment, about the potential benefits that may still be derived from ecological habitats. The perfect workings of the earth's biomes cannot be understood from the perspective of a demos that is not schooled in science, biology, ecology, geology, and other natural sciences. In their ignorance or negligence, human beings continue to rapidly bring devastation and irreversible pollution on the global natural environment. An important consideration is that humans….

I DON'T HAVE THE LAB CONNECTION INFORMATION TO COMPLETE THESE TWO ASSIGMENTS BELOW.
In evolutionary biology, parsimony is similar to the Ockham's razor hypothesis, or that nature will use the simplest method possible to effect change over time.
Phylogenetic systematics is the manner in which biologists reconstruct the pattern of events that have led to evolution and the distribution of unique species. The statement "DNA is the genetic material for all prokaryotes and eukaryotes" implies that DNA is the locus material for evolutionary change.
Assumptions include that there is a strong possibility that some evolutionary changes occur in a regular, clock-like manner. For instance, over millions of years, mutations build up in DNA at a reliable rate, and then are expressed in regular changes.
These assumptions may be violated based on punctuated evolution and/or environmental changes (climate, population, extinctions, or gaps in the ecological system) that change the nature of the timing of mutation expression.
C. Yes, using molecular clocks to estimate divergence of species depends….
Biology of Behavior
The biology of human behavior is rooted in the fact that human beings are animals, in the sense that they are biological creatures and are the result of millions of years of evolution with a physical make up that forms us into creatures that are fitter and more suitable for surviving and adapting to the physical environment all together. Even though a human being is still an animal the biology of our human behavior is impacted by a wide variety of circumstances. One of these circumstances is the fact that we have something that no other animal has: an intricate social structure. "We gather in families, tribes, clans, nations. We have an incredibly sophisticated method of interacting -- speech. We can communicate over time and distance through printing and broadcasting. Our memories are the longest, our interactions the most intricate, our perception of the world simultaneously the broadest….

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.
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.
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.
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….
Lactose is the natural sugar found in milk. An enzyme in the small intestine, lactase, is responsible for the digestion of lactose. Lactase "breaks the lactose down into two simpler forms of sugar, which can then be absorbed into the bloodstream." For most people, this is a straightforward process but some people have insufficient lactase, and indigestion occurs as a result of the body's inability to break down the lactose (WebMD, 2014).
Proteins are digested in both the stomach and the small intestine. The stomach secretes hydrochloric acid and pepsinogen, and the two interact to produce pepsin. The pepsin enzyme then breaks down the protein via a process known as hydrolysis. This is where a water molecule is inserted between two amino acids, causing their bonds to break.
The hydrochloric acid breaks down the bonds between proteins, and the proteins are disintegrated into amino acids. Protein digestion continues in the small intestine,….

Blood is a transportation mechanism, moving gas, waste and nutrients throughout the body. Some are dissolved in blood, but oxygen is transported by the erythrocytes. Blood is a regulator, for example helping to regulate the body's pH and water balance. Blood is also a protector. Some blood cells (leukocytes) attack invading cancer cells, for example, and other pathogens. Blood also clots, which helps to protect the body against blood loss. Platelets are an….

An Inconvenient Truth
In Al Gore's documentary an Inconvenient Truth, he makes some very pertinent points about the issue of global warming. Included in the documentary are the following topics.
a) Effects of Global arming:
Gore uses graphs to clearly illustrate some of the dangerous ramifications of global warming. One chart shows the increasing amounts of carbon dioxide in the atmosphere and data which indicates a rise in temperature is the result of this additional carbon dioxide. The average amount of carbon dioxide in the atmosphere used to be between 180 and 280 parts per million (ppm). It is now above 400 ppm. Gore and the experts in the film estimate that it will rise to 600 ppm.
b) Melting Glaciers:
He asserts that the increased temperature is leading to melting of glaciers. He uses photographs as evidence of his assertion. The researchers also say that these are just some of the things that are….
A punnett square is a two by two square which is used to predict the possible phenotypes of offspring, and its ratio. (Krough)
b) The male and female gametes contain only one set of alleles. (Krough)
c) The genes of the parents go on the outside of the boxes. (Krough)
d) The possible gene outcome from the parental genes goes inside the boxes. (Krough)
e) The punnett square always contains only 4 boxes or squares, that is, two rows and two columns. (Krough)
a) The Law of segregation is based on Mendel's pea plant experiment where he came to the conclusion that alleles for a trait separate when gametes are formed and are randomly paired at fertilization, after which one allele is expressed dominantly while the other is masked. (Krough)
b) Law of independent assortment states that alleles separate independently during gamete formation, which means that traits are inherited by offspring independently of each other.
