Coprophagy is important for the nutritional balance of rabbits and their relatives.
The behaviors of the rabbit, rat, mouse, hamster, guinea pig and chinchilla have all been linked to coprophagy, which is the act of an animal re-consuming its own discharged excrement. Cecotrophy is a better name for it.
The omnivorous rats, mice, and hamster display cecotrophy to a lesser level than herbivores' hindgut fermenters like the rabbit, guinea pig, and chinchilla. In order to boost the supply of folic acid and vitamin B12, it may rise during pregnancy and lactation.
Coprophagy is an intrinsic behavior triggered by the reflex, despite the fact that modern diets make it unnecessary for survival.

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.
<span>The role of a restriction enzyme is essentially used to cut a single gene from a larger piece of DNA. It has a very important role to play in experiments investigating cloning, and in the construction of particular DNA molecules.</span>
Starvation? the human population can grow so much where we populate faster than we eat food and we use up all of our resources (food).
Answer:
Histone proteins act to package DNA, which wraps around the eight histones, into chromosomes. Histone modifications act in diverse biological processes such as transcriptional activation/inactivation, chromosome packaging, and DNA damage/repair.
