Explanation / Answer

4) Micro organisms

5)A part of an experiment that can be changed or varied during the course of the experiment is called a variable. Theory is a broad explanation for a long number of observations and tested hypothesis. Control consists of all the features that the experimental group has; except for the manipulation which has been hypothesized about.

6)Computer science

7)Inductive reasoning

8)Peer review

10)cell

11)Can not Reproduce

12)Nucleus is an organelle which is enclosed by a membrane and contains the genetic material of cells.
Prokaryotes are single-celled organisms which lack mitochondria, a membrane bound nucleus, and any other organelle that is membrane bound. All living organisms do not contain a membrane enclosed nucleus. Bacteria are prokaryotes and are enucleated.

13)A population is: A community of organisms and their nonliving environment. The environment where an organism lives. A group of individuals of the same speciesthat live together in the same area at the same time.

15)A diagram which shows the evolutionary relationships between various biological species on the basis of similarities or differences in the physical or genetic traits is known as a phylogenetic tree. Recently evolved organisms are not placed at the base whereas the least evolved or the most primitive organisms are placed there. Nodes are used to connect branches and therefore, recently evolved organisms are not placed at the nodes or within the branches.
