Interesting biology question.

In order to answer this question, I hope you understand what is mitosis: cell division that creates two diploid "daughter" cells that are identical to each other. Gametes, remember, are the reproductive cells (egg cells and sperm).

If human gametes were made by mitosis, which is not true, because gametes are made in meiosis, they would simply be diploid with somatic cells. The two gametes would have 92 chromosomes, as each cell has 46 chromosomes. And after each generation, the number of chromosomes would keep doubling, which would be very weird. Remember that the normal amount of chromosomes that a human being has, is 46. Maybe humans would have mutations if that happened.

Strike441 [17]

Answer:

  • Bats are very unique and interesting organisms, as they live all there life away from sunlight, they are considered to be the most advance of all the predators just because of having a sonar system inbuilt in there body system. While, they feast on there food outside the place where the remain most of the time and those places are caves.
  • Now, caves are more then just we exactly know, caves comprises of the different level of organisms and they play a very vital role in the over all balancing of the ecological system.        
  • As, there are some insecticides, and other large organisms which then feast upon the bodies of bats corpses or when they are injured due to some reason. So, they play a vital role in the over all ecological food system inside the caves as well.

The nerves that control voluntary responses like those connected to your muscles are part of the _____ nervous system.
Murljashka [212]
<span><em><u>SOMATIC NERVOUS SYSTEM</u></em>

The neuron, a cell that composes the nervous system. For example a brain, an organ composed of thousands of neural fibers and glial cells that performs many important organismic functions. 
Neurons are specialised cells that have dendrites, axons and terminal buttons that sends and receives stimuli from the environment and transduces it into a meaningful information and understand the complexities which the brain now functions. </span>

From the sensory organ received by the sensory neuron the message is sent to the brain and then back to the motor neuron to the muscle or organ responsible.

Degeneration of the dopamine-releasing neurons of the ________ is the ultimate cause of Parkinson's disease. Degeneration of the
slavikrds [6]

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.
