Answer:
<em>The correct option is d) once the electrical impulse reaches a certain level of intensity (its threshold), it fires and moves all the way down the axon without losing any intensity.</em>
Explanation:
In the field of biology, the all-or-nothing law can be described as a principle which focuses on the strength with which a nerve or muscle fibre responds to a particular stimulus, this strength being independent of the strength of the stimulus. The functioning of the impulse is just like the trigger of a gun. The more the force of a stimulus, the more will be the intensity of the nerve impulse.
Answer:
4.Only DNA serves as the master copy of an organism's genetic code which must be replicated by unzipping and base pairing before the cell divides.
The organelle in the plant that will most likely store the absorbed herbicide waste is the vacuole. Vacuoles act as storage bubbles in plant cells. They could store various materials such as food or nutrients to help the plant survive. It can also store waste materials to prevent them from contaminating the entire cell.
Answer:
Reservoirs
Explanation:
Glaciers serve as reservoirs in the water cycle since they can store water for long periods of time. A biogeochemical or nutrient cycle is composed of
- reservoirs, in which the biogeochemical or nutrient is stored, and
- the several processes by which the biogeochemical or nutrient is cycled between its reservoirs.
