How can there be further research on viruses and how can it be improved?
Answers
Answer: 3 Ways Viruses Have Changed Science for the Better
A virus is nature’s efficient little killer. It can invade a cell, take over its inner machinery, trick it into making more virus DNA and escape with a new posse of virus children (often killing the host in the process). They’re really good at what they do, and we’ve been able to harness their skills to learn about – and potentially improve – human health in several ways.
Viruses Show Us the Truth About DNA

A virus called Phage T2 played a starring role in experiments that proved DNA contains the stuff of life.
We take it for granted that life is coded in DNA, but in the 1950s many scientists thought proteins contained our genetic material instead. A virus called bacteriophage T2 helped clinch the debate in DNA’s favor in what are now famously known as the Hershey-Chase experiments.
T2 creates copies of itself by injecting its genetic material into bacteria, where it uses the cell to reproduce. Alfred Hershey and Martha Chase created two sets of radioactive T2 viruses – one with glowing protein and one with glowing DNA – and set them loose on bacteria.
The experiment showed that infected bacteria lit up only when exposed to glowing DNA, proving that DNA had been passed on to the cells, while the glowing protein was discarded. Here’s an animated explainer from UC Davis.
Viruses and Genetic Engineering

Bacteria-eating viruses helped scientists discover a new way to genetically modify cells in just about any organism – including humans.
Bacteriophages are viruses that reproduce by injecting their DNA into bacteria, often killing the bacterium in the process. But in the 1980s, it was discovered that bacteria have a natural defense system, and scientists have recently learned to use this system to engineer DNA on command. It’s called CRISPR/Cas9, and it’s proving to be a cheap, fast and accurate way to manipulate DNA in the lab.
A powerful “search and replace” tool, CRISPR/Cas9 allows scientists to “train” cells to hunt down specific genes to disable them, and even to repair faulty genes by swapping in single genetic “letters.” Many believe that CRISPR/Cas9 will be used to treat diseases in the near future. Scientists recently used CRISPR/Cas9 to successfully modify human T cells to better fight HIV and cancer.
Giant Viruses and Stargates

Scientists keep finding bigger, stranger viruses, and it’s kind of jarring.
In 2003, scientists accidentally discovered the largest virus ever recorded. It’s called the Mimivirus and, after 10 years of suffering from mistaken identity, genetic sequencing proved that it was not bacteria but the strangest virus anyone had ever seen. It’s about 20 times bigger than the average virus and it contains genes previously thought to belong only to cellular life.
And it has a stargate: a five-pronged opening on the side of the virus’ head opens to release genetic material, infecting a host cell to create more viruses. Fortunately, it only attacks amoebas.
But Mimivirus isn’t alone. Since 2003, scientists have discovered three more giant viruses. The latest, Pithovirus, was discovered last year in 30,000-year-old Siberian permafrost – and it turns out it’s still infectious after a good thaw.

What is a fundamental tenet of the wellness model?
Answers
The wellness model's primary tenet is that mental health occurs on a continuum, rather than as a binary condition of "well" or "ill."
Wellness model implies that there is no one "right" way to be mentally healthy, and that each person's experience with mental health is unique.
Preventative care is also emphasized in the wellness concept. This entails taking actions to enhance mental health and prevent mental disease from occurring in the first place.
The wellness paradigm also recognizes that biological, psychological, and social elements all have an impact on mental health.
Mental health, according to the wellness model, is a dynamic process rather than a static condition. This means that, depending on a variety of conditions, mental health might improve or deteriorate.

From Erikson's description of the different stages in Lesson 3, do some of them seem to make
sense in your own life? How?
Answers
Yes, some of Erikson's description of different stages seem to make sense in my own life. For example, Erikson's psychosocial crisis/task for the adolescent stage (teens - 20s) is identity vs. confusion. Being a teenager, I have definitely experienced times where I contemplate if I fit into a certain group or not. I'm still trying to figure out my true identity, although I'm sure that it takes many more years for this question to be actually answered. Erikson's psychosocial crisis/task for the elementary school stage (6 yrs - puberty), which is competence vs. inferiority, also seems to make sense in my own life. I remember feeling inferior or jealous when I did not get to participate in certain activities. Overall, Erikson's description of different stages seem to make sense in my own life for the most part, but I think that his descriptions can vary for many people since everyone varies in their personal values, ideals, and beliefs.

Freud's view of children's development during the preschool years focuses on which two stages
Answers
Freud's view of children's development during the preschool years focuses on the phallic stage and the latency stage.
Between the ages of 3 and 6, children go through the phallic stage, during which they become aware of their gender and experience the Electra complex in girls and the Oedipus complex in males, which are unconscious sexual urges for the parent of the other sex. The emergence of the superego, or the internalized moral and ethical principles that direct behavior is another feature of this period.
The latency period, which lasts from ages 6 to 12, is characterized by the suppression of sexual urges and the development of social and cognitive abilities in young children. Before the start of the teenage stage, this stage is seen as a time of growth that is relatively tranquil and stable.

Which adjuvant targets salivation?
Answers
An adjuvant that targets salivation is pilocarpine.
Pilocarpine is a drug that stimulates the salivary glands, increasing the production and secretion of saliva. It is commonly used as an adjuvant therapy to manage dry mouth, a condition known as xerostomia. Dry mouth can result from various causes such as medication side effects, radiation therapy, or autoimmune diseases.
By increasing salivary flow, pilocarpine can relieve the symptoms of dry mouth, including difficulty swallowing, speaking, and tasting. Pilocarpine works by activating muscarinic receptors in the salivary glands, leading to increased saliva production.
It is available in various forms, including tablets, lozenges, and mouthwashes. However, pilocarpine may have side effects such as sweating, flushing, and nausea, and it is not recommended for everyone.

What is the net filtration pressure of the glomerular capillaries?
Answers
The net filtration pressure of the glomerular capillaries is the difference between the hydrostatic and colloid osmotic pressures, which affects urine production and fluid balance in the body.
The net filtration pressure of the glomerular capillaries is the difference between the hydrostatic pressure and the colloid osmotic pressure within the glomerulus. The glomerulus is a network of small blood vessels in the kidney that filters blood and produces urine.
The hydrostatic pressure within the glomerulus is primarily determined by the blood pressure in the afferent arteriole, which is the artery that brings blood to the glomerulus. The colloid osmotic pressure within the glomerulus is determined by the presence of proteins in the blood. These proteins exert an osmotic pressure that tends to pull fluid back into the capillaries.
The net filtration pressure is the difference between these two pressures, which determines the rate of fluid filtration through the glomerular capillaries. Typically, the hydrostatic pressure in the glomerulus is higher than the colloid osmotic pressure, resulting in a net outward pressure that favors fluid filtration from the capillaries into the Bowman's capsule.
The net filtration pressure is an important factor in determining the rate of urine production and the regulation of water and electrolyte balance in the body. Any changes in the net filtration pressure can affect kidney function and the body's overall fluid balance.
