Answer: False.
Meat is a good source of protein. There are nine essential amino acids which are required under special conditions like illness.
These are-  Histidine, Leucine, Isoleucine, Valine, Threonine, Methionine, Lysine, Phenylalanine and Tryptophan. They cannot be synthesized by the body and therefore need to be taken from external protein sources.
Since meat contains all the essential amino acids, therefore it is considered as a good source of protein. Hence, the given statement is false.

Answer: A gene is a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. A chromosome is a long DNA molecule with part or all of the genetic material of an organism. A allele is one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

Speed = distance / time = (420 x 1000) / (6 x 3600) = 19.44 m/s
        
             
        
        
        
The overload principle is defined as working harder as the body essentially grows fitter. This is to stimulate muscle hypertrophy against resistance as well as overall cardiovascular health. For instance, an experienced body builder should lift more weight up up to failure to grow even fitter.
