<span>This is false since plants are mostly producers and animals are mostly consumers. There is however a group of animals that are autotrophs and create their own food, but they are vastly outnumbered by consumers. The ones that produce their own are mostly within the family of funghi or similar things that border on whether they're animals or plants.</span>
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).
Pathogens are any form of a disease causing bacteria, virus or any other microorganism. When they infect an organism, that organism now has to allocate precious resources in the form of energy in order to fend off the infectious microorganisms. In some other cases, an infection could be fatal to an organism completely and "stability" wouldn't really be the biggest worry for that organism.
In conclusion, if you're talking about a larger, more evolved organism with a working immune system. Pathogens require a lot of energy to fight, and for some small organism without a developed immune system, pathogens could throw them off completely.
