A person who has cerebrospinal fluid draining from the ear probably has a fracture of the temporal bone.
<h3>What is Cerebrospinal Fluid?</h3>
All animals have cerebrospinal fluid (CSF), a transparent, colorless bodily fluid that is present in the tissue that covers their brains and spinal cords.
Specialized ependymal cells in the choroid plexus of the brain's ventricles create CSF, which is then absorbed in arachnoid granulations. About 125 mL of CSF are present at any given moment, and 500 mL are produced daily. The CSF protects the brain inside the skull mechanically and immunologically by acting as a shock absorber, cushion, or buffer. The cerebral autoregulation of cerebral blood flow is another essential role played by CSF.
The ventricular system and subarachnoid space, which are located surrounding and inside the brain and spinal cord, respectively, are occupied by CSF.

Answer: Option B
Explanation:
In a typical energy pyramid the amount of energy that is being transferred is only 10% rest of the energy is lost in the form of heat.
The energy from the sun is converted in the form of chemical energy which is stored in the producers.
10 per cent of this energy is transferred to the next trophic level and rest of the energy is lost in the form of heat. This goes on, there is only a transfer of 10 % energy from the successive levels.
So, if the producers have 200 Kcal/m2/year energy the the primary consumers will have 10% of this energy which is equivalent to 20 Kcal/m2/year and then the secondary consumers will have 10 % of 20 Kcal/m2/year which is equivalent to 2 Kcal/m2/year.
They have the ability to store DNA
