False. When using the 40X objective, you should not use the coarse adjustment knob.
Explanation:
The coarse adjustment knob is used with lower power objectives if used at high powers the lens may get broken and also it would be difficult to attain desired focus. The coarse adjustment knob is used to attain the focus of the object by maintaining the distance between the object and the lens. This is the rough focus knob of the microscope and the focus of the object moves very quickly when using coarse adjustment.
Answer:
Radiation
Explanation:
Radiation is the transfer of heat by means of electromagnetic waves.
In photosynthesis, light dependent and independent reactions are the two set of
reactions that occur.
In light-dependent reactions, the energy from sunlight is absorbed by
chlorophyll and converted into chemical energy in the form of electron carrier
molecules like ATP and NADPH.
In light-independent reactions (the Calvin cycle), carbohydrate molecules are
assembled from carbon dioxide using the chemical energy harvested during the
light-dependent reactions.
Answer: Osmosis is the spontaneous net movement of solvent molecules across a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on both sides.
Explanation:
a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
2.
the process of gradual or unconscious assimilation of ideas, knowledge, etc.
