Answer:
Animalia
Explanation:
If we talk about Eukaryotic and multi-cellular organisms, only three kingdoms come in mind, Plantae, Animalia and Fungi.
In plantae, plants are able to make their own food through the process of Photosynthesis.
Fungi are heterotrophic like animals but they cannot move from one place to another.
Animalia is a Kingdom where organisms are able to move from one place to another but are not able to synthesize their own food like humans, Lions, monkeys etc.
Therefore answer in Animalia

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.
