Answer:

fast- flowing areas usually contain more oxygen than slow-flowing ones.

Explanation:

looking at the statement that accurately compares fast-flowing and slow-flowing areas of stream and water, we need to understand how they flow. a stream flow downhill and it can also flow in a perfect channel, except when flooding occurs and water overflows its channel and spread out across the area of the land. so, fast-flowing generally have higher levels of dissolved oxygen more than slow-flowing because slow-flowing are aerated.

Answer:

The correct option is: <em>a deficiency of dopamine in the substantia nigra.</em>

Explanation:

The substantia nigra is the principal site involved in the physiopathology of Parkinson´s disease.

Cells from this area degenerate and die progressively causing important degeneration in the central nervous system. The cells that die -with no known reason- are those that produce dopamine and proportionate dopaminergic innervation to the encephalon. In fact, almost all the symptoms exhibited by patients with the disease can be explained by the lack of dopamine in the substantia nigra.  

This area uses the neurotransmitter to communicate neurons from the base ganglia. Ganglia are responsible of modulating and modifying movements.

The nigrostriatal system participates in planning and automatic execution of learned movements. When the ganglia activity decreases, so it does the amount and velocity of movements, something typical of the disease.

What is the difference between DNA pol 3 core and holoenzyme?
Dima020 [189]

Essentially there is not an answer. There are two different definitions.

A holoenzyme is an enzyme that needs to be together with a cofactor(s), required for activity.

In some cases, enzymes constituted by several subunits (like DNA polymerase 3) are call holoenzyme as well, because it will only perform correctly when all its subunits are present.

A scientist was studying bones from an individual who died thousands of years ago. Which portion of the bones was the scientist
ludmilkaskok [199]

Answer: Minerals

Explanation: The body decomposes and after about 40 to 50 years bones are mostly brittle and dry with no traces of flesh. After thousands of years bones also disintegrate (decay) leaving brittle mineral frame. The life of bones is determined by the soil type its buried in, nuetral soils takes longer then acidic soil condition.

In this case osteocytes(bone cells) are the first to decompose followed by the cartilage and bone marrow, leaving behind mineral traces that scientist can study after thousand years.
