Answer:
D shrub clippings
Explanation:
this is because they don't decompose like the other choice and are not rich in nutrients
The controlled experiments are performed by the scientists, when they want to study the changes in the sample on changing a single variable. So, the correct answer is option (b).
In case, all variables are kept same, no changes would be observed in the experiment sample. A controlled experiment can be performed on living thing as well as non living. But, controlled experiment cannot be performed on the things which are influenced by a lot of variables, as they cannot create realistic results. So, the option (a), (c), and (d) are incorrect.
Answer:
The functional groups that define the two different ends of a single strand of nucleic acids are:
B. a free hydroxyl group on the 5' carbon a free hydroxyl group on the 3' carbon
G. a free phosphate group on the 5' carbon
Explanation:
A nucleic acid is a polymer formed of nucleotides that are linked with a phosphodiester bond. The structure of a nucleotide consists on a phosphate group linked to a pentose (ribose in RNA and deoxyribose in DNA) that is also attached to a nitrogenous base. The nitrogenous bases are adenine, guanine, cytosine, thymine (in DNA) and uracil (in RNA).
DNA and RNA are nucleic acids which can be found in a double or single strand presentation.
Nucleic acids are synthesize in the 5’ to 3’ direction, so that is why the convention is that the sequences are written and read in that direction.
The strand of a nucleic acid is directional with an end-to-end orientation, where the 5’ end has a free hydroxyl or phosphate group on the 5' carbon of the terminal pentose, and the 3’ end has a free hydroxyl group on the 3’ carbon on the terminal pentose (ribose/ deoxyribose).
It is a good idea to create models of how populations are changing so that we are able to take a better look into what is causing it, if it is a bad or good thing that is taking place, how socioeconomic status may be playing an affect on the changes ect. It can also show if there are concerns coming on the horizon by looking at the change and poll shifts.
