Answer:
1) Skull and Vertebral column
2) Meninges
3) Cerebrospinal fluid.
Explanation:
Central Nervous system:
CNS is the abbreviation of Central Nervous system. CNS controls the whole body functions so it is the most important component of the body. CNS consist of two parts 1) Brain and 2) Spinal cord
Both of these organs are very important and hence need to be protected. Nature provided these organs with certain protective mechanisms these includes
1) Skull and Vertebral column:
Skull is present around brain and vertebral column is present around spinal cord. These structure provides mechanical support to soft parts of CNS.
2) Meninges:
These are the membranes that provide antiseptic environment to the brain and hence protect it from microbes and other harmful substances.
3) Cerebrospinal fluid:
This fluid is present inside meninges which nourishes the brain and protect it from mechanical stresses.
Answer: D.) a suggested answer to a problem
Explanation:
A hypothesis is a supposition, suggested answer or a proposed explanation based on limited evidence which can be use to start an investigation. A hypothesis is more than a guess but less than a established theory and it can be tested through study and experiments.
<u>A hypothesis is part of the scientific method </u>because it is a prediction which can be tested and the results from those experiments may disprove a hypothesis, but can never entirely prove one.
It is not a conclusion because it is an idea which tries to explain an observation. It is not information collected from experiments because hypothesis are formulated before carrying out the experiments and it is not a widely accepted idea because it just proposes a tentative explanation about a phenomenon.
