Answer:
The correct option is: c. in blood
Explanation:
A kidney is a bean-shaped organ, that is present below rib cage in the retroperitoneal space. In vertebrates, the kidneys are present in pair. Each kidney receives blood from the paired renal arteries. The main function of a kidney is to filter the urea present in the blood with the help of filtering units, called the nephrons.
Answer:
Nitrogen is a critical limiting nutrient in many systems, including forests, wetlands, and coastal.
During fertilization, a _sperm_ and _egg_ combine to form a _zygote_.
Sperm and egg (gametes) are both haploid, and the fertilized zygote is diploid.
In the field of medicine we have a short adage that goes, "To cure sometimes, to treat often, to comfort always." Some say it was Hippocrates himself who said this. With that in mind, doctors should always have the patient's welfare in mind always. To improve relations with the patient, the doctor must do a lot of things to show respect. One of them includes simply sitting on a chair with an open stance and leaning slightly forward at an angle while the patient is talking to show that you are interested in what he or she has to say. Never hold the door knob while the patient is still talking as this is a sign that you want him to leave as soon as possible. Never look at far away things, like paintings on the wall or a clock, while the patient is talking because this is another sign of disinterest. And always allow the patient to express his or her self fully without interruption. There are more ways to improve patient relations but these are some good pointers to begin with.
As water molecules from plant leaves evaporate, they attract the water molecules that are still present in the plant, aiding in the movement of water from the roots up through the stems. The water in a plant is transported from the bottom to the top by the combined effects of transpiration and capillary action.
- Water molecules ascend up the cellulose tubes from the roots to the leaves because they tend to cling together (cohesion) and stick to the walls of tubes (adhesion). The water from the leaves then evaporates, aiding in the root system's ability to absorb additional water. We call this mechanism capillary action.
- Water and minerals travel upward from the roots through the xylem due to a negative water potential gradient created by the evaporation of mesophyll cells in the leaves. Small perforations between vessel elements must be made to reduce gas bubbles in the xylem since they can obstruct water flow in the plant.
