Answer:

substantia nigra

Explanation:

The Limbic system is a complex set of brain structures that can be seen on both sides of the thalamus. It supports a variety of functions including emotion, behavioral activities,motivation, memory e.t.c.  It composition entails the hypothalamus, the hippocampus and the amygdala.

The hypothalamus which is  located below the thalamus (i.e hypo means "under") helps to regulates thirst, body temperature, and sexual behavior, and helps maintain a steady (homeostatic) internal state of the body of an organism.

Hippocampus is the centre of memory.

Amygdala (an almond-shape set of neurons) play a key role in the processing of emotions.

On the other hand, The substantia nigra is a basal ganglia structure that can be seen in the midbrain. The substantia nigra plays a vital role in reward and movement.  This area of the brain  sends signals down the spinal cord to control the muscles of the body.

DochEvi [55]

Both species would share both habitats because their niches would be different and competition would thus be eliminated.

A habitat is an area where an organism/species makes its home, which can be represented by all the resources present in that area. Conversely, a niche is the role of a particular species/organism within an environment. In consequence, a niche refers to the position of the organism/species within its community as a consequence of its adaptations, which is unrelated to the physical area it occupies.

In other words, the term habitat indicates how the environment impacts the organism/species while the term niche indicates how the organism/species impacts the environment.

Competitive exclusion indicates that two or more species can't have the same niche in a particular habitat and coexist. In this case, both species can coexist because they share habitats but their niches are different (it occurs when species have restricted diets and therefore their niches do not overlap).

Most of the training of animals is learned from
elena55 [62]

Answer:

Most of the training of animals is learned from  <u>conditioned response</u>.

Explanation:

A conditioned response is a learned response to a previously neutral stimulus. This is achieved by pairing a neutral stimulus with an unconditioned stimulus, which doesn't require any conditioning to cause a reaction.

For example, the smell of food is an unconditioned stimulus that causes the feeling of hunger. This type of response to food is an unconditioned response. If we paired another stimulus, for example, the sound of a whistle, with the smell of food, this stimulus on its own would eventually start causing hunger. This makes the sound of the whistle the conditioned stimulus and feeling hungry after hearing the sound of the whistle the conditioned response.

Most of the animal training is based on this principle.

In order, duck's phases of ending a relationship are:
emmasim [6.3K]
Duck viewed relationships as a series of events. There are four main phases, in which the perception of the people involved in the relationship changes due to strain from different factors.  The phases are:

1) Intra-psychic phase
The individual does not express dissatisfaction or unhappiness with the relationship yet but feels it.

2) Dyadic phase
Discussion regarding the negative feelings is usually carried out in this phase, and anger and guilt tend to rise.

3) Social phase
The separation of the two individuals is shared socially and both choose their own friends and supports for this phase.

4) Grave-dressing phase
This phase occurs some time after the relationship has ended, and the individuals will look back thinking of all the things they did correctly, while also recollecting the negatives of the other person. Trust in relationships is rebuilt in this phase as the individual becomes ready for a new relationship.
