Science for environment health peace and equity​
zhenek [66]

Environment:

Science helps the environment because it creates an understanding between human impacts and the environment. By gaining this understanding of how the natural world works, the human race will better know how to protect it. In addition, scientific research is being used to reduce the impact of global warming, adapt to climate change, clean up polluted areas, and protect our own health.  

Health:

Science can be used to improve global health because it fuels discovery, informs the public on  health risks and programs, and helps all people live healthier and better lives. People with physical and mental health can benefit greatly from a variety of health sciences that specialize in their specific ailment. There have also been improvements in the technology used in health such as sanitation, vaccinations, and monitoring systems. By enabling doctors to do minimally invasive surgeries and using more comfortable scanning equipment, patients spend less time recuperating and can spend more time doing what they enjoy.

Peace:

It is my opinion that communication is the main way that science influences peace. Scientists from all over the world collaborate in an unbiased way to focus on one main goal, to deliver scientific breakthroughs to people regardless of religion, race and culture. Furthermore, science contributes to the social and economic development in a society (such as GDP, life expectancy, and literacy), reduction of poverty (through new was to meet basic needs for food, clothing, and shelter), and inspires a newfound peace mindset.

Equity:

Peace is a strong piece of science and, therefore, equity. Science is heavily rooted in the creation of new knowledge, the improvement of education, and the improvement of the quality of human life regardless of bias. Because of this, science can be used to research and find ways to solve pressing issues like racial and economic inequity. Learning of science in schools also has an impact on equity by teaching children the basis of our world and how to understand in order to gain skills that lead to better economic and social outcomes.

Mutations rII1 and rII2 are known to fall into the rIIA and rIIB cistrons (genes) respectively. Cells of E. coli B are infected
viktelen [127]

Answer:

the answer is A. E. coli B

Explanation:

The multiplicity of infection (MOI) refers to the ratio between the numbers of viruses used to infect <em>E. coli</em> cells and the numbers of these <em>E. coli </em>cells. Benzer carried out several experiments in order to define the gene in regard to function. Benzer observed that <em>E. coli </em>strains with point mutations could be classified into two (2) complementary classes regarding coinfection using the restrictive strain as the host. With regard to his experiments, Benzer observed that rII1 and rII2 mutants (rapid lysis mutants) are complementary when they produce progeny after coinfect E. coli K (where neither mutant can lyse the host by itself). The rII group of mutants studied by Benzer does not produce plaques on <em>E. coli</em> K strains that carry phage λ (lysogenic for λ), but they produce plaques on <em>E. coli</em> B strains. This study showed that rIIA and rIIB are different genes and/or cistrons in the rII region.
