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: 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: Exobiology
Explanation:
Study of Life in outer space or search of life external to Earth is known as Exobiology.
Correct Answer: within fibrous membranes
Correct Answer: All of the above
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
Correct Answer: FALSE
Explanation:
Cytoplasm does not contains all the organelles.
Correct Answer: plasma membrane
Correct Answer: bacterial viruses attack specific cells
Explanation:
Phage typing is based on the fact that bacterial viruses attack specific cells. Phage typing is a method used for detecting single strains of bacteria. It is used to trace the source of outbreaks of infections.
