The correct answer is b. Head movement → Inner ear receptors → Vestibular nerve → Cerebellum.
The balance and equilibrium of the body is maintained by inner ear in the human beings. The parts of internal ear which takes part in balancing and equilibrium are the semi-circular canals and the vestibule. On the movement of head, the otoliths are pull in the direction of gravity.
i think u should ask the doctor because thats like doctor stuff
Answer:
The correct answer will be option-A
Explanation:
Chromosomal abnormalities are caused when the chromosome pair fails to disintegrate through a process called non-disjunction. The non-disjunction of chromosomes usually takes place at the anaphase I or II of meiosis I which involves the X and Y chromosomes.
The abnormality observed with 45 chromosomes or reduction in one sex chromosome or 45, XO is caused when one X copy of a chromosome is completely absent in the cell.
The cause for the loss of one chromosome is the non-disjunction during meiosis I.
Thus, option-A is the correct answer.

Answer;
- 100
Researchers have identified about 100 substances that are made in our body and brain that act as neurotransmitters.
Explanation;
-Neurotransmitters are the chemicals which allow the transmission of signals from one neuron to the next across synapses. They are also found at the axon endings of motor neurons, where they stimulate the muscle fibers.
-Neurotransmitters enable neurotransmission, which is the process by which signaling molecules (neurotransmitters) are released by the axon terminal of a neuron (the presynaptic neuron), and bind to and activate the receptors on the dendrites of another neuron.
