<span>The fluid flows through the interventricular foramen into the third ventricle, is augmented by fluid formed by the choroid plexus of this ventricle, and passes through the cerebral aqueduct to the fourth ventricle, which also possesses a choroid plexus. The CSF from all theses sources , as well as any formed in the central canal of the spinal cord, escapes from the fourth ventricle into the subarachnoid space through the median aperture and lateral aperture.</span>
Answer:
D. Nitrogen-14 has 7 electrons, 7 protons, 7 neutrons nitrogen-15 has 7 electrons, 7 protons, and 8 neutrons
Explanation:
In an atom, number of electrons is equal to the number of protons. And the number of neutrons is equal to the difference between the mass number of the atom and the atomic number. For Nitrogen 14, electron is 7, proton is also 7 as number of electrons and number of protons are equal. So, the neutron will be 14-7= 7. For Nitrogen 15, electron number is 7 so proton number will be also 7. Neutron number for nitrogen 15 will be 15-7= 8. That's why the answer is option number 4.

D. All of the above are true.
Answer:
The recombinant frequency between T and S is 18%;
The correct Sequence of genes is T-A-S
Explanation:
The table below shows the recombinant frequency between heterozygous height and nose morphology:
Tall-uptrend snout 40% Expected
Dwarf-downtrend snout 42% Expected
Dwarf-uptrend snout 9% Recombinant
Tall-uptrend snout 9% Recombinant
Sum Total 100%
To calculate the recombinant frequency; we have :
=9+9
=18%
Hence, the recombinant frequency between T and S = 18%
The determinant of the corect sequence of the genes is T-A-S
