As both biology and society are emergent systems, they must be constantly researched to understand how they are changing. Thus, the two inescapable biological requirements for survival and reproduction must be studied in a dialectical manner in order to understand how they are evolving. How is science and technology connected with society? The essence of…

The developing brain is easily molded, making it highly responsive to experience and stimulation. Enriching environments will support healthy brain development, but exposure to stress and adverse childhood experiences (ACEs) can result in changes to the brain that can impact behavior and the capacity for learning. How does our environment influence our biology? Positive experiences,…

A gene is a portion of DNA that determines a certain trait. An allele is a specific form of a gene. Genes are responsible for the expression of traits. Alleles are responsible for the variations in which a given trait can be expressed. Is locus and allele the same? The key difference between allele and…

However, how we understand ‘change’ differs in each case. Biological death involves understanding intrinsic or real changes to the material what-ness of existence, whereas social death involves an understanding of narrative change of who we are. Biological and social death depend on an existence condition. What are the three aspects of death? Aspects of Death.…

Hydrolysis. Polymers are broken down into monomers in a process known as hydrolysis, which means “to split water,” a reaction in which a water molecule is used during the breakdown (Figure 3.1. 2). How are biological polymers formed and broken down? Monomers are generally linked together through a process called dehydration synthesis, while polymers are…

Yes, if your grandchild meets the IRS tests for a qualifying child you can claim them as a dependent. Can a grandparent claim a grandchild on taxes without permission? Yes, you can claim your grandchild, if he is under 19. The non custodial parent, and his child support, is not relevant. The fact that his…

Another example of this theory at work is to look at individuals who exhibit different disorders such as anger. A believer in this perspective would look at the genetic makeup of the individual to see if they have received a trait from either parent which would contribute to these feelings of anger. What is the…

Essentially, psychology helps people in large part because it can explain why people act the way they do. With this kind of professional insight, a psychologist can help people improve their decision making, stress management and behavior based on understanding past behavior to better predict future behavior. How does biological influences affect behavior? The biological…

The system of DNA profiling used today is based on PCR and uses simple sequences or short tandem repeats (STR). This method uses highly polymorphic regions that have short repeated sequences of DNA (the most common is 4 bases repeated, but there are other lengths in use, including 3 and 5 bases). What are tandem…

B cells are activated when chemicals are released from T helper cells. They are also activated when the antibody molecules on their cell surface bind to a complementary antigen. Different B cells have different shaped antibodies on their surface, so only the B cells with the correct-shaped antibodies will be activated. How do B lymphocytes…

Cracker Barrel recently made major changes to its popular all-day breakfast menu. The new Build Your Own Homestyle Breakfast now features more variety, including a plant-based Impossible Sausage and a Stuffed Cheesecake Pancake, served with strawberry syrup. What has happened to Cracker Barrel cheese? Kraft said it has sold cheese products branded “Cracker Barrel” in…

Traditional DMARDs target the entire immune system, whereas biologics work by targeting specific steps in the inflammatory process, and JAK inhibitors block action in your body to help prevent the inflammation from even starting. What are biological DMARDs? Biologics are DMARDs that are made using molecular biology. They are made up of proteins. Biologic DMARDs…

Salt solution contains Na+ and Cl- ions. When ions are present in the solution, these ions can move through the solution to carry an electric current. How do salt solutions conduct electricity? Salt solution such as sodium chloride (NaCl) conducts an electric current because it has ions in it that have the freedom to move…

Parker Jaren O’Donnell Rosie and Kelli adopted their first child, a son named Parker, in May 1995 when he was just a newborn. Today, at 25, Parker O’Donnell is married and serves as a Marine. Is Rosie adopted Caillou? About Rosie She is Caillou’s 2-year-old sister. She is also the daughter of Boris and Doris…

Small nonpolar molecules can easily diffuse across the cell membrane. However, due to the hydrophobic nature of the lipids that make up cell membranes, polar molecules (such as water) and ions cannot do so. Why can’t polar molecules cross the cell membrane? Large, polar molecules (e.g. simple sugar – glucose): The size and charge of…

Therefore, according to evolutionary psychology, attraction is nature’s way of motivating you to mate with the fittest, healthiest partner available. Of course, nowadays, the advent of modern medicine has led to vast improvements in health. What are the biological factors of attraction? Smell. A study this year found women with certain scents are more attractive…

In the state of Kansas, if a parent is absent for more than six months, they may lose their parental rights. This can happen if the parent is in jail, prison, or if they have been deployed in the military. Can my husband adopt my son if the biological father is not on the birth…

Cats used for dissection are purchased from ‘Class B’ dealers who obtain cats from a variety of legal and illegal sources, such as animal shelters, ‘free to good home’ ads, and pet theft. These animals are sold to biological supply companies, which sell them to schools and colleges/universities for dissection. How do they get frogs…

Psychological theories of crime say that criminal behavior is a result of individual differences in thinking processes. There are many different psychological theories, but they all believe that it is the person’s thoughts and feelings that dictate their actions. What is the biological theory in criminology? The biological theory of criminology says that individuals who…

Count the number of different species and the total number of each individual species inside the quadrat, such as plants, birds, insects, etc. After you finish collecting data in one area, randomly move your quadrat to another location to measure and compare biodiversity in more than one area. What does ecological diversity measure? Alpha diversity…
