Answer:
Horns and columns.
Explanation:
The spinal cord is the important component of the central nervous system. The spinal cord consists of the nerves of the body and control the reflex actions of the body.
Spinal cord consist of white matter and grey matter. The motor and sensory axons are present on white matter. The white matter covers the grey matter and arranged into the different columns. The grey lies inside the white matter and consists of neuronal cell bodies. The grey matter is completely organised in the horns.
Thus, the answer is horns and columns.
Answer:
<u>Perilymph</u> is a fluid similar to cerebrospinal fluid that fills the space between the bony labyrinth and the membranous labyrinth.
Explanation:
The inner ear consists of the bony labyrinth and the membranous labyrinth, it is filled of endophilia and surrounded by perinfilia (the bony labyrinth surrounds the membranous, between both there is a space occupied by the perilymph). Perilymph is an albuminous fluid that has an ionic composition similar to the extracellular environment, it bathes the tympanic and vestibular ramps, fully occupying the bony cavities of the inner ear, bathing the membranous parts located inside these cavities.

Answer:
Thermosphere.
Explanation:
The thermosphere and the exosphere together form the upper atmosphere. ... Because there are relatively few molecules and atoms in the thermosphere, even absorbing small amounts of solar energy can significantly increase the air temperature, making the thermosphere the hottest layer in the atmosphere.
Answer;
The three statements that are true, include;
A diploblast has no mesoderm.
A pseudocoelom has the same functions as a true coelom.
In a coelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the tissue lining the outer side of the body cavity.
Explanation;
-Diploblastic animals are animals possessing two major tissue layers. These include the outer layer (the ectoderm) and the inner layer (the endoderm). Unlike the triploblastic animals , the diploblastic animals lack the third middle layer, the mesoderm.
- Coelom is the body cavity which exists between the mesoderm and endoderm while pseudo coelom is the body cavity which is present inside the mesoderm. Both the coeloms and pseudocoeloms are used as hydrostatics skeletons.
-Coelomate animals are animals that have a "true" body cavity or coelom and organs are in cased in peritoneal membrane.
