Development of the neural groove is known as neurulation
gastrulation
organogenesis
O involution

The correct answer is - neurulation

Explanation:

The neural groove is a groove of the neural plate which is a thick plate that is enclosed by the neural folds of an embryo. The neural grove forms the neural tube which expands and develops into the spinal cord and brain.

The development of the neural grove is taken place during the process known as neurulation which is characterized by all characteristic development related to the neural groove and ventricular system.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
