Given what we know about the diet of the Ethiopian wolves, we can confirm that their prey can be classified as rodents.
<h3>What are Ethiopian wolves?</h3>
- The Ethiopian wolves are a canine native to Ethiopia.
- They are carnivores and hunt in packs.
- Despite their name, they more closely resemble foxes or jackals.
- They feed on rodents such as rats and hares.
Therefore, given their diet based primarily on animals such as hares, giant mole rats, and grass rats, we can confirm that the prey of the Ethiopian wolves can be classified as rodents.

Answer:
a. substantia nigra
b. substantia nigra (it is repeated)
Explanation:
Parkinson's disease is a neurodegenerative disease that is caused by the death of neurons that release the neurotransmitter dopamine in the <u>substantia nigra</u>, or locus niger, -a region of the brain that regulates brain circuits that give the 'orders' to initiate voluntary movements- .
The lack of this neurotransmitter leads to the occurrence of the main symptoms suffered by patients: decreased movements, muscle stiffness, postural instability and tremor. These failures are generated by the abnormal way in which neurons work in the absence of dopamine through a mechanism that is not known in depth.
It is the second most frequent neurodegenerative disease, after Alzheimer's disease, with a prevalence of 2% in people over 65 years. The characteristic symptoms of stiffness, bradykinesia and tremor are associated with losses of neurons in the substantia nigra and dopamine depletion in the striatum. There are large cytoplasmic inclusions, called Lewy bodies, which are the pathological mark of the disease and appear predominantly in neurons that contain melanin of the nigra substance. Genetic studies in a subgroup of families with Parkinson's disease with autosomal dominant inheritance found a locus on chromosome 4q-21 23 and a mutation in the gene that encodes a synaptic protein, α-synuclein.
The answer is C. A variety of antibiotics
