Answer: Characteristics: The fins are supported by rays, as the name indicates. In contrast to the cartilaginous fish they have a rigid skeleton. The swim bladder is also a unique feature of most ray-finned fish, enabling them to maintain buoyancy as they move up or down in the water.
Answer:
Nucleic Acids are precursor for Proteins.
Explanation:
Proteins are formed( protein units called amino acids) by the decoding of specific nucleic acids to give specific Proteins.
No nucleic acids don't provide energy, these are building block of genetic material (DNA). While Proteins provide energy.
No proteins don't carry genetic information.
Yes structure of protein is determined by nucleic acids because each nucleic acids code fir specific unit of amino acid which join to form protein.
No subunits of nucleic acids are nucleotides where as subunits of Proteins are called amino acids.
Please mark it branliest if the answer is little bit satisfying.
The work done is 137 joules.
Lifting opposes the acceleration of gravity, which is 9.8 m/sec/sec.
20 x 0.7 x 9.8 = 137 J (kg-m2/sec2)
it's very practical, because it's on base 10, so conversion between stuff like meters to kilometer is always just a multiplication with 10 to some power
like 1 km = 1000m (10³m)
or 1 m = 10^-3km = 0.001km
same reason for other SI units.
except time, that's base 60, or 12, or 24. that's more complicated, but there isn't any real competition
