Answer:
The water flowing in rivers still originates from precipitation, but it is not all from surface runoff. This groundwater seepage is vitally important to the hydrologic settings of the world because it is responsible for keeping water in rivers during times of no rainfall. Also, the evaporative phase of the cycle purifies water which then replenishes the land with freshwater. The flow of liquid water and ice transports minerals across the globe. It is also involved in reshaping the geological features of the Earth, through processes including erosion and sedimentation.

(here is another example)
Answer:
good and yes I agree we need positivity
Answer:
The correct answer is a. greater than
Explanation:
The partial pressure of oxygen in alveolus is greater than partial pressure of oxygen in deoxygenated blood in a pulmonary capillary and this concentration difference is important for the movement of air(oxygen) from the alveolus to the pulmonary capillary because gases move from higher concentration to lower concentration.
By this process the oxygenated blood reaches to the heart from lungs and heart then pump this oxygenated blood to other body tissues.The partial pressure of oxygen in alveolus is 104 mmHg and in venus blood is 40 mmHg.
Answer:
The <u>tissue level</u> of organization is defined as a group of cells working together to perform a similar function
Explanation:
According to the hierarchical level of organization of human anatomy, a group of cells along with the extracellular matrix combine, ensemble and work together and perform a similar function at the tissue level of organization. Depending upon the location and polarity, cells group together and form a tissue.
The basic types of tissues formed by the grouping of similar cells include muscular, nervous, epithelial, and connective tissues. For ex., a group of cells combining to form epithelial tissues are found lining the skin and internal cavities with the main function to cover and protect the body surface as well as internal cavities.
Answer:
(A) - The volume of the blood plasma increases on overhydration and decreaes on dehydration.
(B) - Osmolality of blood increases with the dehydration and decreases with the overhydration.
Explanation:
If the levels of drinking water is increased, then the plasma becomes more dilute and the plasma volume increases because <u>the water will be reabsorbed more and which as a result reduces plasma concentration of the solutes and increases volume of plasma.</u>
Plasma osmolality measures electrolyte-water balance of the body. <u>As mentioned, above on overhydration, the plasma concentration of the solutes decraeses which also decreases osmolality. So, Osmolality of blood increases with the dehydration and decreases with the overhydration. </u>Increased osmolality in blood stimulate the secretion of antidiuretic hormone which results in the increased water reabsorption and therefore, more concentrated urine and hence blood plasma with less concentration.
