Answer:
Urologist
Explanation:
The person who is involved in the study of the genitourinary system of both males and female is known as the urologist.
The genitourinary system is the system of the organs which are involved in both the sexual and urinary function in the body. The word is formed by the uro from urine and logist- for the person who studies forms the word urologist.
Thus, the urologist is the correct answer.
The crust is the outermost “skin” of Earth and variable thick- nesses; it is thickest under mountain ranges (70 km) and thinnest under the mid- ocean ridges (3 km).
In the given case, most probably the top layer is of oil.
As oil is not soluble in water, it will float on the top of the water surface, in the given case it is the beaker. The oil will always float on top of the water, as it is less dense in comparison to water. The water and oil do not mix as the molecules of water are more fascinated with each other than in comparison to the molecules of oil.
As water is polar and oil is nonpolar, their molecules are not attracted to each other.
Step-by- step Explanation:
- Since the percentge is gradually decreasing a point will come when it will be Zero. Therefore number of trophic level is limited and typically less than 10.
- If we properly look at the pattern 100%>10%>1%>0.1%. We observe that, only ten percent of available energy is transferred from one trophic level to the next.
- Now, if we look at the structure of the model, The box representing the primary consumer is larger than the boxes representing other consumers Thus, we can conclude that, Among the consumers in the ecosystem, first level consumer have the most available energy.
Thus , sclaims B,C and D supported by the model.
Paper chromatography is an efficient method since it uses little material and is relatively quick. The partitioning principle is used in paper chromatography for separations. Substances are divided between a stationary phase and a mobile phase in paper chromatography.
An analytical technique for separating coloured compounds or substances is paper chromatography. Since alternative chromatography techniques like thin-layer chromatography have taken its place in the laboratory, it is now largely utilized as a teaching tool (TLC). Two solvents are used in two-dimensional paper chromatography, which rotates the paper 90 degrees between solvents. This is helpful for sorting out complicated mixtures of chemicals with comparable polarity, like amino acids. There are three parts to the setup. A solution that rises the stationary phase as a result of capillary action is known as the mobile phase. The stationary phase typically consists of polar inorganic solvent water, while the mobile phase typically consists of a combination of non-polar organic solvents. In this instance, the stationary phase, water, is supported by paper. Polar water molecules are trapped in the cellulose network of the host paper's empty space. In contrast to paper chromatography, which uses less absorbent paper as its stationary phase, TLC uses a layer of adsorbent (often silica gel or aluminium oxide) as its stationary phase.
