Answer:
DNA is located in the nucleus of eukaryotic cells.
Explanation:
Answer:
The generation of nitric oxide is done by almost every kind of cell present in the human body, it is one of the essential constituents that plays an important function in maintaining proper health of blood vessels. The nitric oxide acts as a vasodilator, that is, it relaxes the blood vessels' inner muscles, thus making the blood vessels to broaden.
Therefore it can be concluded that nitric oxide enhances the flow of blood and thus reduces the blood pressure. In this manner, nitric oxide helps in tackling the symptoms of conditions like angina.
At the molecular level. the activation of guanylyl cyclase is done by nitric oxide, which further catalyzes the production of cGMP. This cGMP further functions as an intracellular messenger in a pathway that results in the relaxation of the smooth muscles.
Answer:
The carrying capacity is different for each species in a habitat because of that species’ particular food, shelter, and social requirements. carrying capacity; exponential versus logistic population growth In an ideal environment (one that has no limiting factors) populations grow at an exponential rate.
The correct answer is: b. The structure of DNA was helical
This photo known as Photo 51 is an X-ray diffraction image of crystallized DNA made by Rosalind Franklin. This photo helped Watson and Crick to define the final structure of DNA molecule. This diffraction pattern was essential for the construction of DNA model and it determined the helical nature of the double antiparallel helix strands.
Both the nitrogenous base and phosphate group are attached to the deoxyribose sugar in DNA.
