Answer:
A. Auxotroph 4. requires at least one nutrient for growth
B. Conjugation 1. requires cell-to-cell contact
C. Hfr 6. E. coli strain with Ffactor integrated into bacterial genome
D. Transduction 7. requires virus
E. F' 5. F factor that has picked up a piece of the bacterial genome
F. Transformation 3. uptake of DNA from external medium
G. Competent 2. capable of taking up DNA
Explanation:
Auxotrophs are those organisms able to synthesize organic compounds required for their growth.
Conjugation is the genetic transfer between bacteria through cell-to-cell contacts.
In bacteria, the Hfr chromosome is linearly transferred from F to F- cells.
Transduction is a genetic process where exogenous DNA fragments are introduced into another cell via a viral vector.
The F factor (fertility factor) is a bacterial plasmid that allows to transfer genetic information between donor and recipient cells during conjugation.
Bacterial transformation is the horizontal transfer of genetic material by which bacteria obtain DNA from its environment.
In bacteria, competence refers to the ability to take up exogenous DNA from the external environment.
The central nervous system has two functions. One, where the brain is, is to be the center of thoughts and the interpreter of outside influences, while the spinal cord connects all parts of the body with the brain.
Answer:
<h2>
Question no 4 answer</h2>
Fossil fuels will still provide 60% of energy in 2040, compared to 85% today, but the pattern of use will change, away from coal and towards gas, and increasingly concentrated in industry. Fossil fuel prices would be lower in a 2˚C scenario, with less need to mobilise high-cost reserves to meet demands.
<h2>
Question no 3 answer</h2>
Carbon emissions trap heat in the atmosphere and lead to climate change. In the United States, the burning of fossil fuels, particularly for the power and transportation sectors, accounts for about three-quarters of our carbon emissions
<h2>
Question no 2 answer</h2>
The premise of this Viewpoint article is that the sustainability of the electricity supply is very often addressed in narrow frames of reference, which sets up incremental decision-making. To more fairly compare the economic, social, and environmental aspects of renewables, such as photovoltaics, to fossil fuels, a broader view is required which needs to take into account the impacts of the fossil fuel supply chain.
<h2>
Question no 1 answer</h2>
These non-renewable fuels, which include coal, oil, and natural gas, supply about 80 percent of the world's energy. They provide electricity, heat, and transportation, while also feeding the processes that make a huge range of products, from steel to plastics.
