Unlike in prokaryotic cells, replication in eukaryotic cells

a. can start in many different places on a sequence at the same time.
b. starts from a single point.
c. involves much less dna.
d. is continuous in two directions until the whole chromosome is copied.

The correct answer is A) can start in many different places on a sequence at the same time.    

DNA replication is a process of copying DNA so that two identical replica of DNA are produced from one original DNA. It is essential for the process of cell division. It is initiated from a specific site/ specific sequence of nucleotides that is called origin of replication.

There is single origin of replication in prokaryotes ( as they have smaller genome size) whereas eukaryotes ( having large genome) have multiple origin of replication so that their whole DNA can be replicated within less time.

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics
