Normative history-graded influences are those influences within the life course that are correlated with historical time and are experienced by the majority of a culture. For example,, wars and epidemics are considered history-graded events. What are the examples of normative life events? ∎ Normative Age-Graded Influences events will be different from one culture to another.…

Place the specimen box into a ziplock bag and seal the bag. Place the ziplock bag in the bottom of the shipping box. If necessary, use sheets of bubble wrap to ensure specimens remain in a vertical position. Fill a Styrofoam-lined shipping box with dry ice. Can liquid nitrogen be shipped? It is used to…

The biological approach to psychopathology believes that disorders have an organic or physical cause. The focus of this approach is on genetics, neurotransmitters, neurophysiology, neuroanatomy etc. The approach argues that mental disorders are related to the physical structure and functioning of the brain. What is the biological influence on mental disorders? What Biological Factors Are…

Little House on the Prairie Laura Ingalls and Willie Oleson were adopted brother and sister in real life. Sara Gilbert, who played Darlene on a popular TV Series Sitcom, is also an adopted sibling in the Gilbert family. Is Matthew Labyorteaux adopted? Labyorteaux was born in Los Angeles and adopted by interior designer and talent…

Glutathione exists in reduced (GSH) and oxidized (GSSG) states. The ratio of reduced glutathione to oxidized glutathione within cells is a measure of cellular oxidative stress where increased GSSG-to-GSH ratio is indicative of greater oxidative stress. Is glutathione oxidized? Glutathione, Oxidized (GSSG) is the oxidized version of the naturally occurring and very important detoxification agent…

Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct. What is biogeography and how does it relate to evolution? Biogeography is the study of how and why plants…

No DNA testing has been reported to determine Farrow’s paternity. According to Tina Sinatra, Frank Sinatra’s youngest daughter, Frank had previously undergone a vasectomy and could not have been Ronan’s biological father. Who does Mia Farrow say is Ronan Farrow’s father? Born Satchel Ronan O’Sullivan Farrow, Farrow is the biological son of actress Mia Farrow…

In an 1835 letter from Edgar Allan Poe, he wrote, “My father David died in the second year of my age, and when my sister Rosalie was an infant in arms”. According to author Susan Talley Weiss, Poe died on December 11, 1811, only three days after Eliza’s death. What age was Edgar Allan Poe…

Some biological and genetic factors affect specific populations more than others. For example, older adults are biologically prone to being in poorer health than adolescents due to the physical and cognitive effects of aging. Sickle cell disease is a common example of a genetic determinant of health. What is the biological determinant of health? Biological…

Calculate the deviation of each measurement. Calculate the squares of each of the deviations (i.e. di2). Add together all the squares of the deviations i.e. Divide by the total number of measurements (i.e. n) to obtain the mean of all the square deviations. How do you calculate SD in biology? Calculate the mean (x̅) of…

A Health Science degree is uniquely different from other science degrees such as biology, physics, or chemistry. Those degrees are highly specific in their scope. By contrast, a degree in Health Science focuses on all topics related to health. This type of science degree concentrates on health problems and outcomes. What is the difference between…

The application of information technology to the molecular field is called bio-informatics. It is a combination of statistics and computer science applied in the field of molecular biology. How computers are helpful in biological sciences? Computers can be used to simulate cellular growth, the human nervous system, motor control, disease transmission, and disease progression. All…

The basic difference between biological transmission and mechanical transmission is that in biological transmission, the agent develops and/or propagates within the vector, while in mechanical transmission, the simple transfer of agents from one infected host or a contaminated substrate to a susceptible host occurs. What are mechanical vectors? Vectors may be mechanical or biological. A…

Let us explore how Biochemistry, which is one of the most preferred science majors, impacts a pre med student and his way of learning to be a successful medical practitioner. In the US, 43% of students who major in Biochemistry get admitted into a medical school followed by general biology (35%). Is biochemistry the same…

The review process Manuscripts judged to be of potential interest to our readership are sent for formal review, typically to three reviewers. The editors then make a decision, based on the reviewers’ advice, from among several possibilities: Accept, with or without editorial revisions. What is in review in nature? In Review is a free preprint…

European green crabs were first introduced to North America in the 1800s, likely traveling in ballast water of merchant ships from Europe. This species has since drastically increased in number and spread to all of New England and as far north as Newfoundland, Canada. Why was the green crab introduced? Green crabs were first introduced…

More than 86,000 biology majors graduate each year, to compete for entry-level positions in research, environmental monitoring, health care and teaching. How many people have a bachelors in Biology? The number of Biology graduates in the workforce has been growing at a rate of 4.1%, from 2.73M in 2018 to 2.84M in 2019. The largest…

By comparing the sequences of genomes of different organisms, researchers can understand what, at the molecular level, distinguishes different life forms from each other. How does the DNA of two individuals that are closely related compare? If the DNA of two unrelated people is compared, you would expect that the 0.1% of DNA that is…

They prefer to feed from tall (3-6 feet high) plants, including blazing star, cosmos, New England aster, Joe-pye weed, Mexican sunflower, purple coneflower, and zinnias. They will visit other nectar plants, though, including red clover and milkweed. The adults only live for about 2 weeks, feeding exclusively on nectar. Why are my Painted Lady butterflies…
