Correct Answer: within fibrous membranes
Correct Answer: All of the above
Correct Answer: the formation of dense bones during youth
Correct Answer: histone octamer
Correct Answer: R-CH(NH2)-COOH
Explanation:
Amino acids are the building blocks of proteins. There are about 21 essential amino acids in the human body like histidine, leucine, lysine... The general formula for amino acid is R-CH(NH2)-COOH.
Correct Answer: Degradation of amino acids
Explanation:
Urea is a by product of amino acid catabolism, Which occurs in the liver. The nitrogen in the amino acid becomes converted to ammonia and this is further converted by the liver into urea
Correct Answer: Understand the behavior of entire biological systems
Explanation:
An approach to studying biology that aims to model the dynamic behavior of whole biological systems based on a study of the interactions among the system's parts.
Correct Answer: Cytokinin
Explanation:
Cytokinins is a Plant hormone which helps in cell division and leads to Growth & formation of shoots, roots & bud.
Correct Answer: Meiosis
Explanation:
The process accounts for species diversity is Meiosis. Meiosis is termed as a specialized cell division which reduces chromosomes number by half and then creates for haploid cells.
Correct Answer: It stimulates appetite and energy storage
