Answer: Option A "Choroid plexus".
Explanation:
Cerebrospinal fluid can be defined as the fluid that is found in the brain and spinal cord of human beings. It is a clear and colorless fluid.
The production of cerebrospinal fluid takes place by the specialized ependymal cells that lies in the choroid plexuses which is present in the ventricles of brain.
The amount of cerebrospinal fluid in a day is 500mL. This fluid acts as cushion that protects the brain from mechanical and immunological protection.
Hence, the correction answer is option A
" a boat sails across the ocean" possess Kinetic energy. hence option d is correct.
<h3>
What is Kinetic energy?</h3>
- Chemical energy, thermal energy, electromagnetic radiation, gravitational energy, electric energy, elastic energy, nuclear energy, and rest energy are only a few of the many different types of energy that exist. Potential energy and kinetic energy are the two basic categories that can be used to group them.
- An object's kinetic energy is what drives its motion. Kinetic energy can be converted into other types of energy and transported between objects.
- The energy an object has as a result of motion is known as kinetic energy in physics. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The body holds onto the kinetic energy it acquired during its acceleration until its speed changes.

Answer:
They are inter-related with each other.
Explanation:
There is a great relationship present between evidence, conclusions and theories because evidences are those materials due to which a hypothesis can be verified and we can draw conclusion. When we repeat the same experiment and find out the same conclusion so it becomes theory and when these theories can't change with the passage of time, it becomes law. So evidence, conclusions and theories are inter-related to each other.
