Cytoplasm does not contains all the organelles.
Correct Answer: It stimulates appetite and energy storage
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: Cytokinin
Explanation:
Cytokinins is a Plant hormone which helps in cell division and leads to Growth & formation of shoots, roots & bud.
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: 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.
