Which of the following is NOT a reaction of the
parasympathetic nervous system?
A. Decreased respiration
B. Decreased heart rate
C. Increased blood flow to digestive tract
D. Decreased saliva production
Answer:
D
Explanation:
D, or decreased saliva production is not a reaction of the parasympathetic nervous system (PSNS) since the PSNS actually increases/causes salivation which helps you digest your food.
As a tip, I usually associate the PSNS with a state of rest/restful conditions, as opposed to the sympathetic nervous system which is the opposite and is associated with stress and high-pressure conditions (like fight or flight).
Hope this helps!! :)

Describe two problems that occur when a human population grows.
Answer:
Explanation:
The exponential growth of the human population could lead to food shortages, global warming, and other issues of resource scarcity.
Answer:
Explanation:
Unsustainable population growth and lack of access to reproductive health care also puts pressure on human communities, exacerbating food and water shortages, reducing resilience in the face of climate change, and making it harder for the most vulnerable communities to rise out of intergenerational poverty.

Do you think people can misdiagnose themselves with the flu? Explain your reasoning.
How is flu season defined? What are the criteria for this definition?
How does the flu affect businesses and governments? Could it affect residents’ access to certain resources?
Explanation:
1) The flu is caused by influenza viruses that infect the and people assume it's the flu because nose, throat, and lungs. These viruses spread when people with flu cough, sneeze or talk, sending droplets with the virus into the air and potentially into the mouths or noses of people who are nearby.
2)
Difficulty breathing or shortness of breath.Persistent pain or pressure in the chest or abdomen.Persistent dizziness, confusion, inability to arouse.Seizures.Not urinating.Severe muscle pain.Severe weakness or unsteadiness.Fever or cough that improve but then return or worsen.3) yes because they don't always know signals can have symptoms as others and they assume it as flu because it is a known sickness
4)The flu, also known as the influenza virus, is diagnosed year-round in the United States. Fall and winter seasons are when the greatest impact is usually seen and, therefore, is considered the "flu season." Influenza activity has a period of greatest activity between December and February, but the activity can last until May.
Every year at the beginning of the fall season, people are encouraged to get a flu shot.
CDC data on influenza vaccine:
• 116 million doses of influenza vaccines have been distributed.
CDC
(Centers for Disease Control and Prevention) recommends that all persons 6 months and older receive the influenza vaccine at the end of October.
• Influenza vaccination offers important benefits

A flu is a common viral infection that can be deadly if not treated on time. This is caused by the influenza virus. The common symptoms include fever, chills, muscle aches, cough, fatigue and runny nose.
What is Flu?
Flu is a viral infection caused by the Influenza virus. This is a communicable disease. The flu virus attacks the lungs, nose and throat. The respiratory system is weakened. People who have a weak immune system or have a chronic disease are more prone to flu infection.
The most common symptoms include chills, fever, headache, muscle aches, runny nose, cough and fatigue. People generally diagnose flu when they are having respiratory illness which doesn't always supposed to be flu. This misdiagnosis can complicate the situation which makes the treatment of infection difficult.
Flu season is an annually recurring period. The season occurs when its half cold in each hemisphere.
Flu is a communicable disease which lasts for approximately two-three days. During this period, an affected person is advised to stay away from other healthy people which interferes with the business and government work. Also, the residents are not advised to go in public which affects their access to certain resources.

Which of the following molecules is synthesized at specific times during the cell cycle and
forms an active complex with a kinase?
A)PDGF
B)MPF
C)Cdk
D)cyclin
Answer:
D. Cyclin
Explanation:
Cyclins drive the events of the cell cycle by partnering with a family of enzymes called the cyclin-dependent kinases (Cdks). A lone Cdk is inactive, but the binding of a cyclin activates it, making it a functional enzyme and allowing it to modify target proteins.
Cyclin is synthesized at specific times during the cell cycle and forms an active complex with a kinase.
The phases of the cell cycle are directed by a highly complex and finely regulated protein interaction network.
Among these proteins, the phosphorylating enzymes called cyclin-dependent kinases (CDKs) and their activating subunits the cyclins (A, B, D and E) stand out.
The cyclin-dependent kinases undergo phosphorylation on their amino acids (serines and threonines).The cyclins (so called because they appear and disappear throughout the cycle), bind to the CDKs and control their phosphorylation reactions.The cyclic assembly between these two compounds, cyclins and CDKs, their activation and disassembly are the central processes that direct the cell cycle.Therefore, we can conclude that cyclin is synthesized at specific times during the cell cycle and forms an active complex with a kinase..

Analyze the example of gene expression of the bacteria below:
In this example, what would cause the genes to be expressed?
An operon that is turned off
Polymerase being blocked from bonding to the DNA
The presence of an active repressor
A repressor that is unable to bond to the DNA
Answer:
This question is incomplete as it lacks the image. The answer is:
D. A repressor that is unable to bond to the DNA
Explanation:
The expression of a gene in a prokaryote like bacteria is regulated at the transcription level. Normally, a Gene is expressed by first undergoing transcription from DNA to mRNA with the aid of an enzyme called RNA polymerase.
However, a protein called REGULATORY PROTEIN which serves as a repressor inhibits the binding of RNA polymerase to the DNA sequence. According to this question, the gene will only be expressed if the repressor is unable to bond to the DNA, hence, not being able to prevent transcription.

The process when rocks break into smaller pieces due to exposure to
natural elements is called
Answer:
Weathering.
Explanation:
Weathering is the breaking down of rocks, soils, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms.
The process when rocks break into smaller pieces due to exposure to natural elements is called weathering.
What is weathering?Weathering can occur through physical, chemical, or biological means.
Physical weathering involves the mechanical breakdown of rocks into smaller fragments without changing their chemical composition. Chemical weathering, on the other hand, involves the breakdown of rocks through chemical reactions, resulting in the formation of new minerals. Biological weathering is caused by living organisms, such as plants and animals, that can physically break down rocks or release chemicals that can alter the rocks' composition.
