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.

1) determine the probability of individuals inheriting a disease
2) In the future, new genetic mutations will arise, and knowing to understand genetics would be important in helping analyze the problem/mutation in genetic recombination.
3) Genetics allows us to link diseases to one another (pedigrees) by analyzing if they are recessive, dominant, and/or autosomal, this allows us, as scientists to be able to identify and classify future diseases, and to determine their inheritance pattern, in the future.
Answer:
A purine always forms a complementary base pair with a pyrimidine.
Explanation:
Purine bases such as Adenine pair specifically with Thymine , a pyrimidine base forming two bonds; just as Guanine pair specifically with Cytosine forming three bonds.
This specific base pairing are complimentary in nature and grants stability to the DNA.
Answer:
A, E
Explanation:
It is more permeable to carbon dioxide such as other gases and also it is permeable to urea because it can make interaction with urea and dissolves it inside the cell.
<h3>Food chain</h3>
A food chain is a chain of different animal species that are dependent on the next as a source of food. If one source dies, then the chain starts to break.
<h3>Food webs</h3>
Food webs are a system off overlapping food chains. Basically meaning, many food chains combined together.
<h3>Pyramid Model</h3>
A pyramid model includes the following:
- Primary Producers
- Primary Consumers
- Secondary Consumers
- Tertiary Consumers
