IRINA_888 [86]

Answer:

The correct answer would be a loss of sensation to pressure and touch.

The dorsal column-medial lemniscus pathway abbreviated as DCML refers to the sensory pathway of the central nervous system (CNS) which transmits sensations of vibration, fine touch, proprioception, and two-point discrimination from the skin as well as joints.  

Thus, injury to the dorsal column would result in the loss of sensation to touch and pressure.

Which plant system is affected when xylem tissue is removed
Gennadij [26K]
The answer is most likely "vascular system". Xylem tissue is a part of a plant's vascular system. Which is mostly responsiple for transportation (of water, food etc.) in a plant. The vascular system of plants is made of two tissues. One is Xylem and the other is Phloem. Phloem transports food from leaves to all other parts of the plant. And Xylem transports water and minerals (which are dissolved in the water) to the leaves. 

So if you remove the <u>Xylem</u> tissue from a plant, its vascular system will be affected.

Svet_ta [14]
Smaller cube (1 cm X 1 cm X 1 cm) 

<span>The surface area of one side = 1 cm X 1 cm = 1 <span>cm2</span></span>

 

<span>There are 6 sides, total SA = 6 X 1 <span>cm2</span> = 6 <span>cm2</span></span>

 

<span>Volume = 1 cm X 1 cm X 1 cm = 1 cubic cm (1 <span>cm3</span>)</span>

<span>Surface to Volume Ratio = 6 <span>cm2</span>/1 <span>cm3</span> = 6 <span>cm2/cm3</span></span>


Larger cube (6 cm X 6 cm X 6 cm) 

<span>The surface area of one side = 6 cm X 6 cm = 36 <span>cm2</span></span>

 

<span>There are 6 sides, the total SA = 6 X 36 <span>cm2</span> = 216 <span>cm2</span></span>

 

<span>Volume = 6 cm X 6 cm X 6 cm = 216 <span>cm3</span></span>

 

<span>Surface to Volume Ratio = 216 <span>cm2</span>/216 <span>cm3</span> = 1 <span>cm2/cm3</span></span>
