Answer:

No specific test exists to diagnose Parkinson's disease. Your doctor trained in nervous system conditions (neurologist) will diagnose Parkinson's disease based on your medical history, a review of your signs and symptoms, and a neurological and physical examination.

Why is redi's experiment a good example of a controlled experiment
Step2247 [10]
A controlled experiment is when the experimenter can change one variable in the experiment and completely change the results.

Redi experiment involved a closed jar with rotting meat on the inside. He waited for a few days and found no new forms of life in the jar.
He then did the same experiment, but this time he took the lid off the jar. After those few days he found there were maggots in the rotting meat from flies.

This is a great example of a controlled experiment, because he only had to change one variable to completely change the results. In this case that variable was just removing the lid from the jar.

Redi was trying to prove spontaneous generation with his experiment. Although, it failed.

Spontaneous generation: When life forms from non-livings.

Redi disproved spontaneous generation, but proved biogenesis.

Biogenesis: When life comes from other living beings.

He proved biogenesis because the flies had reproduced when the jar was opened.

What makes gymnosperms especially suited for northern climates?
babymother [125]
1) Long slender leaves ("needles") because:
a) They don't lose a lot of water from photorespiration b/c of low surface area
b) Snow doesn't pile into the branches and break the branches off (snow is very heavy). the needles don't catch and hold very much snow.
2) The wood is soft and bendable. Strong wind doesn't break it, because it flexes. Any snow that does manage to pile on is dropped when the wind blows, or when the weight of the snow bends the Branch down.
Hope this helps! :)

"what would be the best approach to curbing excessive human population growth?"
Ghella [55]
The best approach to curbing excessive human population growth is extensive public education programmes and distribution of family planning methods in countries with high fertility rates. Most countries with high fertility rates have large numbers of the population living in poverty and this limits the access people may have to modern methods of contraception.
