The correct answer is option D, that is, nitrogen and phosphorus.
Nucleic acids refer to the macromolecules comprising oxygen, hydrogen, phosphorus, and carbon. They are the small biomolecules or the biopolymers, playing an essential role in all the known forms of life.
They comprise nucleotides that are the monomers formed of three constituents, that is, a 5-carbon sugar, a nitrogenous base, and a phosphate group. If the sugar is obtained from ribose as deoxyribose, then the polymer is DNA, and if the sugar is a compound ribose, then the polymer is RNA.
Answer:
QP = 41
Explanation:
Its geometry its easy...
Since its getting cut through the middle that means they equal each other
3x + 5 = 5x - 19 (Use a calculator)
x = 12
Since your solving to find QP you plug it into QP
3(12) + 5 = 41

Answer:
1. Cartilaginous joints
2. Freely movable (Synovial) joints
3. Temporomandibular joint
4. Arthritis
5. Synchondrosis
Explanation:
1. Cartilaginous joints are those who permits some movements but provide less stability that immovable joint, these joints are slightly movable.
2. Freely movable joints are synovial joints. These joints have a joint cavity between connecting bones, and allow for greater mobility. However, they are less stable than fibrous and cartilaginous joints. For example: elbow.
3. Temporomandibular joint is a like a hinge and a ball and socket joint at the same time. It is a simple hinge that permits to chew.
4. Arthritis is a term that describes inflammation in joints. Some of them include: rheumotaoid arthritis, psoriatic arthritis, etc.
5. Synchondrosis is a joint in which the articulating surfaces are close together but are bound by a hyaline cartilage, which can converts to either bone o fibrocartilage.
According to the top down control, each trophic level is controlled by the very next trophic level. It says that predators control the population of prey.
