In a mixture of sand and rock in gravel, different components are easily observed. Which term best describes this mixture?

The neural pathway bringing temperature information from your left hand to the somatosensory cortex would have two synapses, with the first being in the <u>spinal cord dorsal horn on the left side</u> and the second being in the <u>thalamus on the right side.</u>

Explanation:

The stimuli received by the external receptors must travel from the place where they are produced to the association centers located in the central nervous system, where the information is processed.

In the case of the sensory nerves, which conduct the temperature-related information from the left hand, it happens that:

They make their first synapse in the posterior horn of the spinal cord, responsible for receiving nerve impulses of sensitivity, on the same side as the stimulus (left).
The second synapse occurs in the thalamus, an organ of the central nervous system that is responsible for receiving information related to temperature. As the sensory and motor pathways are crossed, the portion of the thalamus that receives the information is the right one.

One of the consequences of the crossing of the sensory pathways is that everything related to one side of the body is processed on the opposite side of the somatosensory cortex.

Match the bacterial shape with its description

slega [8]

Answer:(A) a cylindrical shaped bacteria exhibiting a variety of rod shapes.- pleomorphic.

B) A bend, or 'coma shapped' rod - Vibrio.

C) Long, curved, flexible rod - spirochete.

D) Long, curved rod - Spirillum.

E) A small, cylindrical shaped bacteria with a cocci appearance - coccobacillus.

F) Cylindrical shape - Rods.

G) Round shape - Coccus.

Explanation:

A). A pleomorphic bacteria is the one which is capable of changing it's shape, mode of nutrition and reproduction.

B). Vibrio is the genus of gram-negative bacteria. It posses a curved comma shape. This is responsible for foodborne infections.

C). Spirochete is a helical, rod shaped bacteria. It posses flexible cell wall and a mechanism that helps in motility.

D). Sprillium is a gram-negative bacteria. It has a rigid spiral structure. It has a long curved rod. It is found in the stagnant water and can also be responsible for causing water borne diseases.

E). Coccobacillus is a bacteria which has shape which is in between cocci and rod. These are very short rods which are mistakenly consider as cocci.

F). A bacillus or bacilliform bacteria is a rod shaped bacteria which can be found in different taxonomic groups of bacteria. These have cylindrical shape.

G) A coccus is the shape of the bacteria which can be consider as either spherical, ovoid or round in shape.
