The right answer is phosphate.

DNA has a double helix structure (discovered in 1953 by James Dewey Watson, Francis Crick et al.).

DNA is a polymer of deoxyribonucleic bases, more commonly called nucleotides. Each nucleotide consists of a phosphate group (or phosphoric acid) bonded to a sugar, deoxyribose, itself linked to a nitrogenous base. These bases are four in number: adenine (denoted A), thymine (denoted T), cytosine (denoted C) and guanine (denoted G). The backbone of the DNA is formed by the sugar-phosphate repetition.

What is the likely long-term consequence of an increase in the relative percent of greenhouse gases in Earth’s atmosphere?
kvv77 [185]

Correct answer: A). Earth’s average temperature will increase.

Green house gases are those gases, which are present in the air that have the ability to trap heat of the earth's surface. Gases like carbon dioxide and methane are  known to be found naturally play an important role in earth's climate. If they are not found the earth' s climate would be too cold creating problem for survival of life on the earth.

They absorb and emit the radiation in the thermal infrared range. These gases act like a blanket and save earth surface from infrared radiation by absorbing them and prevent them from escaping out of the earth surface.

But due to increased in the concentration of green house gases like carbon dioxide and methane in the environment due to pollution and deforestation is causing a great problem, which result in a global warming, which is a great concern for all the people on the planet. It will increase the annual global temperature which will result in the melting of glaciers. So, the issue of global warming should be taken seriously and adequate measure should be taken to control it.

In Griffith's experiments with Streptococcus pneumoniae, rough nonencapsulated streptococci were converted into smooth encapsula
larisa86 [58]

Answer:

The correct answer is - transformation.

Explanation:

Griffith's experiment was performed by Fredrick Griffith with Streptococcus pneumoniae. Streptococcus P. are rough non encapsulated streptococci that are converted into smooth encapsulated streptococci bacteria in presence of heat-killed smooth encapsulated bacteria.

This experiment was the first experiment that showed that this bacteria can get DNA by the process of transformation.

He suggested that the nonencapsulated bacteria had been transformed into the encapsulated smooth bacteria strain by the transformation process that was somehow part of the dead encapsulated strain bacteria.

Thus, the correct answer - transformation.
