When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the C. experimental. Experimental variables are the things you are studying in the experiment and it is the only variable you can change.
Answer: C, chromosome replication
Explanation:
A, B, and D only occur in meiosis, as crossing over is required for genetic variation, which isn't needed in mitosis, reduction division is when diploids are reduced to haploids, which only happens in meiosis, and homologous chromosomes making tetras doesn't occur in mitosis either. However, during interphase of both mitosis and meiosis, chromosomes (DNA more specifically) are replicated.
Answer:
Central nervous system includes brain and spinal cord. Peripheral nervous system includes autonomic nervous system and somatic nervous system.
Explanation:
Nervous system consists of electrically excitable cell called neurons and collection of nerves that transmit information in the body.
Nervous system is mainly divided into two parts - PNS (peripheral nervous system) and Central nervous system (CNS) . The CNS of the body consists of spinal cord and brain that regulates and coordinates all the functions of the body.
PNS consist of cranial and spinal nerves. This system is divided into Autonomic nervous system ( controls involuntary actions of body) and somatic nervous system ( control the voluntary actions of the body).
Answer:
A cell takes in DNA from outside the cell then the external DNA becomes a component of the cell's DNA. ... a gene that makes it possible to distinguish bacteria that carry the plasma (and foreign DNA) from those that don't.
