A neural tube is a structure of the embryo which helps in the formation and development of the spinal cord and the brain. So when a few cells are removed from the neural tube in an experiment on frog embryos, this would cause an effect on the development of the nervous system.

Answer:  A. Development of the nervous system is affected

Explanation:

An embryo is a primitive stage of development of a young organism. It is produce by the fusion of the haploid gametes of parents so as to produce diploid zygote. The cells of zygote of animals and humans proliferate and divide to form embryo which consists of specialized cells which give rise to specialized structures and organs like heart, lungs and brain necessary for performing vital functions like circulation, respiration and control and coordination.

According to the given situation, if few cells are removed from the neural tube of  a developing embryo then the specialized cells which are responsible for formation and proper functioning of the nervous system will be affected. Overall development of the nervous system will be hampered.
