As <span>Motor and sensory neurons are located in the leg and brain, respectively and the receptor is probably a part of either of those  it's not located in the vertebra. So we can say that the part of the nerve that may block the nerve impulse is the Interneuron. Hope this helps.</span>

The broken vertebrae controlling the reflex arc of the leg movement can be temporarily blocked by the interneurons. The reflexes are controlled by the central nervous system, and interneurons are a part of it (the brain and the spinal cord). The pathway of the reflex arc of the leg movement from the sensory neurons and then back to the motor neurons will be blocked by the interneurons as the vertebrae is broken.

Hence, the answer is 'interneurons'.

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown answer

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown in the diagram attached.

Given;
            x + y + z = 140 meters


According to the proportion theorem,

\frac{x}{40} = \frac{y}{30}

Solving for x, using cross multiplication:

\frac{x}{1} = \frac{40y}{30}

Similarly,

x/40 = z/35

solving for z by cross multiplication,

z = 35x/40
z = 7x/8

Now, the third proportions,
y/30 = z/35

Solving for y,

y = 30z/35
y = 6z/7

x + y + z = 140

 4y/3 + 6z/7 +  7x/8 = 140

(224y + 144z + 147x)/168 = 140

224y + 144z + 147x = 23520

Substitutoing z = 7x/8,

224y + (144 × 7x/8) + 147x = 23520

224y + 126x + 147x = 23520

224y + 273x = 23520
Now,
Substitute y = 3x/4

(224×3x/4) + 273x = 23520

168x + 273x = 23520

441x = 23520

x = 53.33

Now,
We know that
y = 3x/4
so,
y = 40

And,
z = 7x/8
Z = 46.66

Natali [406]

Answer:

C. Synthesis of organic molecules

Explanation:

According to chemical evolution theory, life originated from inorganic molecules by the mode of chemical evolution. In primitive conditions of earth, only inorganic molecules were present. These molecules reacted under lightning, UV radiation and other environmental conditions to give rise to complex organic molecules like amino acids, sugars, lipids etc. They formed the basis for proteins, RNA and other molecules which ultimately led to the formation of cellular structures.
