Safety has been called a “dynamic non-event” because when humans are in a potentially hazardous environment, it takes significant work to ensure nothing bad happens.
What is safety?Safety is described as the state of being "safe", the condition of being protected from harm or other danger. Safety can also refer to the control of recognized hazards in order to achieve an acceptable level of risk.
Therefore safety has been described as a "dynamic non-event because in order for this "non-event" of nothing going wrong to occur, a lot of things must be done right.
Hence our best answer is that it takes significant work to ensure that nothing bad happens. When things go right in a potentially hazardous environment, nothing bad happens.

It has been repeatedly shown in wild populations using both experimental and observational methods.
Due to the fact that people who possess both forms of a gene are more likely to survive than people who only have two copies of one version, balanced polymorphism occurs when two distinct versions of a gene are kept in a population of organisms.

Which human activity would most likely decrease the amount of carbon in the atmosphere?
A. clearing forests
B. heating coal
C. burning wood
D. planting trees
Answer:
[tex]\huge\boxed{\sf Option\ D.}[/tex]
Explanation:
Trees absorb carbon dioxide and release oxygen. In this case, carbon dioxide in the atmosphere decreases and oxygen in the atmosphere increases.
Hence, we should plant more trees in order to decrease the amount of carbon dioxide in the atmosphere which is the main cause of global warming.
[tex]\rule[225]{225}{2}[/tex]
The fourth option.
Also known as "D."
I chose this option because as trees grow, they remove Carbon Dioxide from the atmosphere. Carbon Dioxide is used in a process called "Photosynthesis" in which plants make there own food using Carbon Dioxide, sunlight, nutrients from the soil, water, etc.
The product produced would be Glucose and Oxygen.
Since Carbon Dioxide would be taken from the plants to make food and breathe, the level of Carbon in the atmosphere would definitely decrease!
Suppose a poison was able to block the gap junctions in the intercalated discs of cardiac muscle cells. How would this affect the ability of cardiac muscle tissue to perform its functions?
According to the research, if a poison was able to block the gap junctions in the intercalated discs of cardiac muscle cells, it would prevent the exchange of chemical and electrical information, key to the cardiac function of cardiac muscle tissue.
What are the intercalated discs of cardiac muscle cells?It is each of the complex junction structures between two cardiac muscle cells, these junctions take place at the z lines of the sarcomeres of the muscle fibers.
In this sense, this large number of nexus-type junctions allows the transmission of nerve impulses that cross from one cardiac cell to another.
Therefore, we can conclude that according to the research, the intercalated discs support the synchronized contraction of cardiac tissue so if a poison was able to block the gap junctions, it would affect the transmission of electrical information.

What does Malthus mean when he writes about the “oscillation” between “progressive and retrograde forces with respect to happiness”?

What is Criticism of Malthusian Theory of Population?Based on the following findings, the Malthusian theory has been criticized:
Rapid population growth was occurring in Western Europe. In parallel, technological advancements had also led to an increase in the food supply.The population has frequently increased faster than food production. For instance, in the US, the agricultural sector employs 2% of the total workforce. The GDP as a whole is still over $14 trillion.According to him, positive and preventive checks can help achieve a balance between population increase and food availability.According to Malthus' theory, a lack of land is one of the factors contributing to a limited food supply. But as globalization has progressed, more food is now available in more nations.Malthus didn't provide any estimates for the population's geometric or arithmetic growth.
