The animals evolved from the habitat they live in . Because the air around them always changes.
Answer: The nervous system as a whole is divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS).
Explanation:
Answer:
B. False
Explanation:
Prior to the replication of a DNA strand or molecule, the double stranded DNA molecule needs to be unwound i.e. separated into two single strands. One strand called the LEADING STRAND that runs from the 3' - 5' direction while the other strand called the LAGGING STRAND runs from the 5' - 3' direction.
The unwinding of the DNA template is carried out by an enzyme called DNA HELICASE, which binds to the DNA molecule and unwinds the double strands into two strands at the same time. This means that the unwinding into leading or lagging strand is not easier than the other since it occurs simultaneously, hence, this question is FALSE.

Common ancestry is identified in the genes. Selection forces are the drives to these physical and composition changes of an organism however, it can be traced back.
Adaptation processes occur to help species survive and thrive in the ecological balance of life. Structural adaptations are physical features of an organism that adapted through time. An example of this are the bills of a bird and the fur of bears that they generally need for their survival; birds for hunting, and bears to protect them from low climate areas.</span>
Answer:
They reproduce.
Explanation:
Reproduction is the phenomenon which involves the production of an offspring by particular individual or individuals to propagate their species. Reproduction is done during reproductive phase. Unicellular organisms are single-celled forms whereas multicellular organisms are made up of many cells.
