Answer:
Neural crest cell movements are inhibited.
Explanation:
Neural crest cells may be defined as the temporary group of cells that are unique for the chordata group. These cells arise from the embryonic ectoderm and give rise to future melanocytes.
Antibodies to fibronectin association is helpful to study the signalling factors. If these anitodies to fibronectin is shown in the embryonical stage. The neural crest migration is inhibited by its exposure to fibronectin and this might hinder the embryonic development.
Thus, the answer is neural crest cell movements are inhibited.

Answer:
The correct statement is that proteins and carbohydrates have the same amount of energy.
Explanation:
The 90 percent of the dry weight of the diet and 100 percent of its energy is supplied by proteins, carbohydrates, and fats. All these macronutrients provide energy to the body, however, the amount of energy in one gram varies, that is, 9 calories in a gram of fat, and 4 calories in a gram of protein or carbohydrate.
These nutrients also vary in the rate by which they supply energy. Of the nutrients, fats are the slowest and carbohydrates are the quickest.
