Parkinson's disease

<h3>What is Parkinson's disease?</h3>

Parkinson's disease (PD) is a neurodegenerative ailment that primarily affects dopamine-producing ("dopaminergic") neurons in the substantia nigra, a particular region of the brain.

In most cases, symptoms appear slowly over many years. Due to the variety of the condition, the evolution of symptoms can vary a little from person to person. People with PD might go through:

  • Tremor in the hands that is typically described as pill-rolling tremor when at rest. There may be additional tremor types.
  • Bradykinesia
  • Limb stiffness
  • Balance and gait issues

Why is the hypothesis that black cats cause bad luck not science?
Alja [10]

Because it has no scientific explanation. As a matter of fact it has no explanation.

The things that black cats cause bad luck are a myth, and do not have any proof or explanation, meaning it cannot be concluded neither as a hypothesis nor scientific.


Hope it helped,

Which group of non-prokaryotic organisms studied in microbiology typically have two life cycle stages: trophozoite and cyst?
Mama L [17]

Non-prokaryotic organisms typically have two life cycle stages: trophozoite and cyst is Protozoa.

<h3>What is Protozoa?</h3>
  • Protozoa is a group of single celled, non- prokaryotic organisms.
  • These may either be free living or parasitic in nature.
  • These are heterotrophs and reproduce asexually by binary fission.
  • The Protozoa consists of many unrelated or loosely related organisms.
  • They are divided into four major groups:  Sarcodina, Flagellates, Ciliates and Sporozoans..
  • Some protozoa consist of two phases in their life cycle: proliferative stage (trophozoites) and resting stage (cysts).
  • Trophozoites consists of the proliferative stage in which the protozoa divides and reproduces.
  • The resting cyst form helps the protozoa to survive harsh environmental conditions like harmful chemicals, extreme temperature and nutrient and water deficiency.

A pharmaceutical company claimed that experiments showed that its drug could effectively reduce the growth of cancer cells by 35
Mazyrski [523]
<span>The labs were unable to reproduce the pharmaceutical company’s data

An important characteristic of scientific experiments is that their results can be replicated. In this case, assuming that the laboratories followed the same procedure as the pharmaceutical company, the fact that the data could not be replicated means that the company's claims are invalid. The validity of the claims is more questionable given the huge difference in the final conclusions, with the company reporting a 35% decrease, while the maximum decrease observed by the labs was 8%.
