How did oxygen affect evolution?.

Answers

Answer 1

Anaerobic environments were home to organisms that were unable to sufficiently adapt to oxygen.

Thus, changes in the composition of the earth's atmosphere, the rise of aerobic metabolism, and ultimately multicellularity were all caused by cyanobacteria's release of oxygen.

How did oxygen influence evolution?

According to new research that was published in BMC Evolutionary Biology, oxygen played a significant role in the evolution of complex organisms. The study demonstrates that, in tandem with the availability of oxygen as an energy source, life complexity increased earlier than previously thought.

Why did organisms use oxygen to evolve?

This is because when organisms metabolize their food, they use oxygen to generate more energy. However, it wasn't until 2.4 billion years ago that the Great Oxidation Event took place.

Answers

Whether a mutation is beneficial or harmful depends on whether or not it helps the organism to survive and reproduce. Option B is the correct answer.

Mutations in organisms can have different effects, and their impact on the organism's fitness determines whether they are beneficial or harmful. Beneficial mutations are advantageous because they provide an advantage to the organism, increasing its chances of survival and reproductive success.

On the other hand, harmful mutations are detrimental to the organism's fitness, reducing its ability to survive and reproduce. Therefore, the determining factor is the effect of the mutation on the organism's ability to adapt and thrive in its environment. Option B is the correct answer.

although many intellectuals wanted to investigate the mentality of nazism, others simply wanted people to remember. many survivors of the concentration camps, such as_____ , wanted others to know what had happened and to not forget.

Answers

One survivor of the concentration camps who advocated for remembrance was Elie Wiesel. Wiesel was a Romanian-born Jewish writer and activist who was imprisoned in Auschwitz and Buchenwald during World War II.

He is best known for his memoir "Night," which describes his experiences in the concentration camps and has become a widely read account of the Holocaust. Wiesel believed that the horrors of the Holocaust should never be forgotten, and he spent much of his life speaking out against genocide and other forms of injustice. He saw remembering the past as a way to prevent similar atrocities in the future. In his Nobel Peace Prize acceptance speech in 1986, he said: "I have tried to keep memory alive...I believe that without memory, there is no future, and without a future, we are lost." Other survivors and their descendants have also emphasized the importance of remembrance, both as a way to honor those who were killed and as a means of educating future generations about the dangers of hatred and prejudice. By keeping alive the memory of the Holocaust and its victims, they hope to create a better world where such atrocities never happen again.

which theorist gave the greatest credence to the power of ideas to shape society? group of answer choices max weber emile durkheim karl marx marvin harris

Answers

Karl Marx gave the greatest credence to the power of ideas to shape society. Marx believed that ideas are not just abstract concepts, but they are produced by material conditions and power relations in society.

He argued that the ruling class uses dominant ideas to maintain their power and control over the working class. Marx emphasized that the ideas and beliefs of society reflect the economic and social relations that exist within it.

According to Marx, the working class must challenge dominant ideas and beliefs in order to transform society and establish a more equitable and just social order. Therefore, Marx's theory of historical materialism highlights the central role of ideas in shaping society, but also emphasizes the underlying material conditions that give rise to those ideas.


Max Weber is the theorist who gave the greatest credence to the power of ideas in shaping society. Weber believed that ideas, values, and beliefs significantly influenced social change and the development of societies. He emphasized the role of culture, religion, and individual motivations in driving social action. In contrast, Emile Durkheim focused on social solidarity and the importance of norms and values in maintaining societal cohesion, Karl Marx prioritized the role of economic and class struggles, and Marvin Harris emphasized the influence of material conditions and practical necessities. Thus, Weber's emphasis on the power of ideas distinguishes him from the other theorists mentioned.

what is the great security against one department growing too powerful? why is it necessary for ambition to counteract ambition?

Answers

Separation of powers prevents one department from gaining too much power. Ambition balances power among the branches.

The great security against one department growing too powerful is the separation of powers, which divides authority among the legislative, executive, and judicial branches of government.

Each branch serves as a check on the others, ensuring that no single branch becomes too powerful.

It is necessary for ambition to counteract ambition because people in power are naturally ambitious and seek to expand their influence.

Therefore, by dividing power among the branches and giving each branch the means to check the others, ambition is balanced and controlled.

This system promotes accountability and prevents any one person or group from holding too much power, thus protecting the rights and freedoms of the people.

Answers

Abnormal psych the observation that, in longitudinal studies of psychopathology, people with the disorder being studied may die before people who do not have that disorder is called Selective mortality. The correct answer is option A.

Selective mortality refers to the observation that individuals with a particular disorder may be more likely to die than individuals who do not have that disorder.

This can create a bias in longitudinal studies of psychopathology because it may affect the representativeness of the sample and the ability to draw accurate conclusions about the progression and outcomes of the disorder.

For example, individuals with severe mental illness are more likely to die prematurely from medical conditions such as cardiovascular disease, respiratory disease, and infectious disease.

This can make it difficult to determine whether the observed differences in psychopathology over time are due to the natural course of the disorder or to the premature mortality of those with the disorder.

Selective mortality is an important consideration in research on psychopathology and must be carefully addressed in study design and data analysis. The correct answer is option A.
