A balance that performs in an enclosed compartment with no air currents to disturb is called an analytical balance.
Analytical balances are instruments used for precise and determination of mass of matter. They are accurate and very precise instruments. They require a draft-free location on a solid bench that is free of vibrations.
Analytical balances of today are digital and have built in calibration weights to maintain accuracy. Older versions usually require to be manually calibrated using specific standard weights.
Answer:
Aldehyde has C=O bonded to atleast one H atom while Ketone has C=O bonded to two carbon atoms
Aldehyde - galactose, glucose, glyceraldehyde, fructose
Ketone - Trioses, Tetroses, Pentoses, Hexoses
Explanation:
Similarity
Both the aldehyde and ketone have C=O group
Difference
In aldehye the C=O group require atleast one hydrogen atom or the functional group in aldehyde is -CHO
while in ketone the function group is C=O only that is bonded to two carbon atoms.
Example
Aldehyde - galactose, glucose, glyceraldehyde, fructose
Ketone - Trioses, Tetroses, Pentoses, Hexoses
A. Nonnative species that are superior competitors
This membrane mimics the plasma membrane that is around animal cells. In order to explore how water moves in and out of a cell, one cell was weighed and then submerged in hypertonic solution. The other egg was weighted and submerged in hypotonic solution. It was predicted that the egg submerged in hypertonic solution would decrease in mass. It was predicted that the egg submerged in hypotonic solution would increase in mass.
Explanation:
The outermost covering of an animal cell is the plasma membrane. It is a selectively permeable membrane that allows only selective molecules to pass through it.
A solution having higher concentration of solute than the cell cytoplasm is called a hypertonic solution.
A solution having lower concentration of solute than the cell cytoplasm is called the hypotonic solution.
The movement of water molecules from the region of its higher concentration to the region of its lower concentration through a semipermeable membrane is called osmosis.
A cell placed in hypertonic solution will undergo exosmosis so it will lose water and its mass will decrease.
A cell placed in hypotonic solution will undergo endosmosis of water so it will gain water and its mass will increase.
The best option is A Coriolis Effect. The Coriolis effect is most apparent in the path of an object moving longitudinally.
