Explanation: The continents were once all together and this has been proved by the modern plate tectonic theory. Sufficient evidences has been provided in support of this theory such as-
The coast-lines of some continents are found to be perfectly match with its neighboring ones. For example, the east coast of America perfectly get fits with the West coast of Africa.
Similar type of plant as well as animal fossils have been found in different continents. For example, the plant fossil 'Glossopteris' is found in India, Antarctica and Australia.
From the stratigraphical point of view, same types of rock are found in different places.
Thus the question satisfies all the provided options.
The peripheral nervous system has - Somatic nervous system and Autonomic nervous system.
These systems control our body action by this controls all the types of muscles.
Explanation:
Somatic nervous system have - Cranial nerves and Spinal nerves
Autonomic nervous system have - Sympathetic and Parasympathetic system.
The somatic nervous system controls our voluntary and involuntary actions by cranial and spinal nerves and controls all three types of muscles such as cardiac, smooth and skeletal.
The autonomic nervous system controls the involuntary actions of our internal organs.
The sympathetic and parasympathetic system relates to all types of muscle.
The sympathetic and parasympathetic system accelerates and decelerates the heart beat respectively, by this controls the cardiac muscle.
The sympathetic and parasympathetic system stimulates and relaxes our internal organs respectively, by this controls the smooth muscles.
The sympathetic and parasympathetic system prepares our body as a whole for a action and also relaxes our whole body respectively, by this controls the skeletal muscles.
Energy can always be transformed from one form to another form.
E.g. Throw a ball in upward direction ,so it will have some kinetic energy due to its mass and velocity. At some height ball will stop and will start coming down.
Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water.Yes.
Hypotonic describes the concentration of salt. Hypotonic is typically when a concentration has a higher solute concentration or salt and less of a water concentration.
Hypertonic is the opposite with a higher concentration of water and a lesser concentration of solute or salt.
