Answer:
Generally, oil immersions are used when one has to witness the cells from the inside and is mostly seen at 100X objective. The oil immersions are used to cope with the RI or the refractive index, as when light goes from a substance of one RI to the substance of another RI the light gets scattered.
One is not able to see the cells when the slide is placed upside down, however, when the slide was turned over then everything becomes clear. As basically when we look through the microscope then initially the top thread comes into focus succeeded by the middle and eventually the bottom one.
However, when one put the slide upside down then at that time the slide function as the first thread and the cells function as the second thread. As the slide is formed of dense and thick substance it is tough to focus the second thread or the cells via it. This is the reason that one is not able to witness anything when the slide is kept in this position.
Sand is more Permeable. It is the smallest, and can diffuse the easiest over a membrane.
Answer:
The correct answer is - option E.
Explanation:
Living organisms and non living materials both are made up of atoms and these atoms are bind together by specific kinds of the bonds such as hydrogen bond, covalent bond and many more that help in determining their shape and structure and determined their physical characteristics.
These organism follow laws of chemistry and physics such as the law of the thermodynamics, law of gravitational force, homeostasis and various kind of forces and interaction.
Thus, the correct answer is - option E.
FALSE.
Cells have greater amount of potassium in it and lower amount of sodium 'cause it is abundant in it's surrounding environment. Cells pumps out their ions in & out of the cell by active transport, and maintains the level.
Hope this helps!
