Answer:

Posterior column mediates a pathway called as posterior column medial lemniscus pathway in central nervous which is responsible for mediating certain sensations like touch, vibration etc. Damage to the left posterior column unable to transmit signals to the primary somatosensory cortex in the gyrus and parietal lobe of the brain.

Explanation:

The spinal cord and cerebrum is connected by some specialized tract called as white matter tract. These tracts are either ascending or descending.

The another name of ascending pathway is known as medial lemniscus pathway.

The origin of this pathway takes place within posterior column of the spinal cord.

Posterior column medial lemniscus pathway is important as it transmit signals to the cerebrum which is responsible for generating impulse like vibration, touch etc.

Thus damage to this column can't be able to transmit signals to different parts of cerebrum and thus impulse like touch, vibration,pressure etc will not generate.

Something that makes reactions start more easily and increase how fast the reaction occurs

That would be catalysts.

Catalysts accelerate (speed up) chemical reactions without damaging itself. They do this by decreasing the activation energy of a chemical reaction.

Enzymes are a type of catalysts.

Dan has noticed that when he adds fertilizer to his garden soil his strawberry plants seem to grow better. Dan wonders if it is

madreJ [45]

The correct answer is - the variable.

With the experiment, in the way that Dan had decided to perform it, the fertilizer is the variable, as in one of the parts with strawberries he uses fertilizer, while in the other part he doesn't uses fertilizer.

While this kind of experiment may give Dan some answers, and he might notice differences, still he would have to be more detailed in the experiment to see for sure if the fertilizer is the thing that makes some of the strawberries grow better than the others.

Dan should also put all of the strawberries at places that would receive the same amount of light, experience the same weather conditions, receive the same amount of water, and to be planted in a soil of the same quality. Only like this, after putting the fertilizer, Dan can now if it makes any changes or not.

Identify the bones and features indicated in this radiograph of the neck

stealth61 [152]

I found this radiography online, i hope it's the same:
1- Spinous process
2- Atlas ( it's the first vertebra)
3- Axis ( it's the second vertebra)
4- Transverse process
5- Intervertebral disc (present between vertebras)
6- body of the vertebra
the occipital bone is a reference that it's the posterior side, while the mandibule indicates it's anterior.
