DNA is a long polymer, made from repeating units called nucleotides. DNA is found in mitochondria, plastid & nucleolus. The two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase either guanine (G), adenine (A), thymine (T), or cytosine (C) as well as a monosaccharide sugar called deoxyribose and a phosphate group. The presence of deoxyribose sugar is characteristic of DNA.

So, the correct answer is option B.

Which are factors of rock types that affect the rate of weathering? Select three options

vagabundo [1.1K]

Answer: Incomplete

"Check all that apply. porosity, moisture, temperature, mineral, softness, or ease of dissolving"

From the options, the three answers are mineral composition, ease of dissolving and p

Explanation:

Weathering is the phenomenon in which surface of rocks are broken down and leaches or washed away.

The factors that affect the rock type and rate of weathering of said rock include:

Composition: this translates to the mineral composition in the rock and how susceptible to chemical weathering reaction
Surface area and porosity: Surface porosity determines how easily the rock can be leached by wind or rain.
Climate: Mechanical weathering due to extreme climate change can cause freezing and thawing of the rocks, thereby enhancing disintegration of the rock. This is determined by the ease of dissolving of the rock.
