Match the component of the midbrain with its function.
IgorLugansk [536]

Answer:

Involuntary motor commands to the erector spinae: it is the tegmentum

Houses the superior colliculi: it is the tectum

Site of neurons that produce dopamine: it is the substantia nigra

Motor axons from primary motor cortex to spinal cord: cerebral peduncles

Explanation:

The tegmentum is an area of the brainstem involved in unconscious perception and reflexive commands. The tectum is localized in front of the tegmentum, which has been involved in motor responses such as, for example, walking, swimming (in fish), etc. The substantia nigra is a region of the ventral midbrain with a high concentration of neuromelanin in its dopaminergic neurons. The substantia nigra has been associated with Parkinson's and Huntington's diseases. Finally, the cerebral peduncles are two structures on each side of the brainstem that attach this component of the brain with the cerebrum. The cerebral peduncles have been involved with motor skills, balance and posture control.

As the feature of being a polyploid makes it easy for any archea to survive in the most severe conditions. As the polyploids contain a number of genetic materials in pair, as each pair is very distinctive in features or more independent in regulating a function then the other. Giving it a more diversity of genetic sequence its genome.

Along, with that the process of meiosis occurs prior to the process or event of cell division. Which is for production of the copies of the parent cell, which posses the same genetic material as that of the parent cells.
