Answer:
The correct answer is hydrogen bonding.
Hydrogen bond is defined as a weak bond that results from electrostatic attraction taken place between hydrogen of one molecule and electro-negative atom of same or different molecule.
In water, partial negative charge is present on oxygen atom which attracts the partial positive charge present on hydrogen atom of other water molecule. This attractive interactions lead to the formation of inter-molecular hydrogen bonding.
Answer:
Explanation:
Long-term memory may involve a change in the shape of the neuron's cytoskeleton.
The long-term memory process involves a structural change with the growth of new synaptic connections by the sensory neurons onto their follower cells.
Answer: c) and b) are correct.
The brain is encased in a protective bony or cartilaginous housing in craniates.
The anterior end of the nerve cord is elaborated to form a brain in craniates.
Explanation: The craniates include the chordata with well-defined heads. This includes mammals, reptiles and fishes. So we can discard the other answers. Because most craniates have functional jaws, and the adults do not lose their chordate characteristics. The last one does not apply as a specific feature because the tunicate have neural crest but are not recognized as craniata.
