Answer: Limited Surface area - Volume ratio
Explanation:
Cells in various organisms usually have the same size be it a blue whale or an earthworm, a Human or a mouse or an Elephant and a squirrel. This is down to the way the cell is structure.
The Cell needs to absorb nutrients to survive while getting rid of waste material. For that to happen it needs an adequate surface area. The problem is that as the cell absorbs more nutrients thereby increasing in volume, this rise in volume occurs at a faster rate than the cell can increase its surface area so the surface area will keep shrinking.
Therefore, in order to have enough surface area to keep up the process of absorption and excrement, the cell will stop growing at the certain point and this process is similar in most if not all organisms.
Answer:
Sensory neurons send the impact of signals received from the senses and it delivers to the brain.
<u>Explanation:</u>
- Sensory neuron is a type of neuron that provides a relay type of information based on the signals received from the active parts of the body.
- Sensory neuron and motor neurons are connected to the central nervous system.
- If a person stubs on his toe, the impact of pain expressed to him is noted by the sensory neurons.
- These sensory neurons travel to the path of the brain after getting a proper signal of impulse from the senses.
- After receiving those signals, the brain sends necessary action to impart those signals.
- So the person feels the effect of pain and makes him to remove his leg from the toe.
