The answer is bone composition. While the other answers are also techniques used to compare bones, the primary techniques would be bone composition. This is because bones of different species vary greatly in the composition of content such as collagen, extractable proteins, and ash content.

g Cerebrospinal fluid formed in the lateral ventricles travels through the ________ to reach the third ventricle.
kolezko [41]

Answer: Interventricular foramen

Explanation:

<u>The cerebrospinal fluid is a fluid that covers the brain and spinal cord. It circulates through the subarachnoid space, the cerebral ventricles and the ependymal canal</u>. Several diseases alter its composition and its study usually detects meningeal infections, carcinomatosis and hemorrhages. Some of its functions are:

  • Hydropneumatic support against local pressure for the encephalon.
  • Eliminates metabolites from the central nervous system.
  • Protects the central nervous system from trauma.

This fluid also fills the ventricles, which are large open structures deep within the brain and help keep the brain buoyant and cushioned. The lateral ventricles are the largest ventricles and connect to the third ventricle through the intraventricular foramen. This third ventricle is a narrow, medial cavity located between the diencephalic masses. <u>Then, the interventricular foramina are channels that connect with the ventricles of the lateral walls and with the third ventricle</u>, at the level of the midline of the brain. Like these channels, they allow cerebrospinal fluid to circulate through the rest of the ventricular system of the brain. The walls of the foramina also contain choroid plexuses, responsible for the production of cerebrospinal fluid, which continue in both the lateral ventricles and the third ventricle. After reaching the third ventricle, the cerebrospinal fluid travels through the median aperture into the subarachnoid space at the base of the brain.

What is a similarity between Animalia and Plantae kingdoms?
zalisa [80]

Answer:

Plant and animal cells have a plasma membrane, a nucleus, mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, peroxides, and micro-tubules.

Explanation:

Both animal and plant groups have few alike structural elements. Leading off, they are both eukaryotic, which indicates they have a specified nucleus. The nucleus comprises chromosomes. It is guarded and enclosed by the cytoplasm, which is a wet or gel-like liquid. Animal and plant cells own a cell membrane that encloses the cell.
