Answer:
Dissolving of solute in a particular solvent depends upon the temperature of the solvent.
Explanation:
Solubility is a amount of solute that can be dissolved in fixed amount of solvent at a particular temperature. It is crucial that the amount of solvent remains constant when a solubility of a substance determined .Here the amount of solvent (water) is kept constant at (100 ml). The variable that is changed the temperature of the solvent.
Suppose a solution able to hold more solute at a particular temperature is unsaturated. A solution is able to hold maximum solute at a particular temperature is saturated. Under certain conditions a solution hold more solute than the maximum amount at a particular temperature is supersaturated solution. Regarding the dissolving of barium hydroxide and potassium chloride is clearly given in a table which is attached.
The glomerulus is supplied blood by the afferent arteriole, then the efferent arteriole takes away blood from the glomerulus.
The afferent arteriole has a larger diameter than the efferent arteriole.
The efferent arteriole, due to its smaller diameter creates some resistance to blood flow causing a blood back-up which creates a high pressure in the glomerular cavity. Therefore fluid and solute are forced out from the blood and into the glomerular capsule. Most of this filtrate is returned to the blood via peritubular capillary bed surrounding the nephron.
Answer: First Third Fourth Choice
Explanation: Becuz when water freezes, the density becomes lower and the bonds stabilize, resulting in the molecules moving apart.
There are several evidences of evolution, some that we have greater knowledge and others we don't, but in this question all alternatives contain evidence of evolution, to understand better we need to know that.......
<h3>Fossil Evidence</h3>
Fossils are remains or traces of preserved organisms that are more than 10,000 years old and provide important information about life in past times and what the environment was like at a given time.
- Bones
- Teeth mark
- Footprints
- and petrified feces are examples of fossils.
<h3> Comparative embryology and Homologous structures</h3>
Some species have anatomical characteristics that are very similar to those present in individuals of other species. Although these structures often do not have the same function, it is possible to infer that, at some point, these species had a common ancestor.
<h3>Biochemistry and Metabolism</h3>
The analysis of cells and the biochemistry of organisms have revealed that there is much similarity between all living beings. This fact suggests that, at some point in evolutionary history, we had a common ancestor.
It can be seen, therefore, that the theory of evolution is supported by several pillars and every day it is more evident that living beings undergo changes over time.
With this information, we conclude that <u>all alternatives are evidence of evolution.</u>
