Answer: venus

Explanation: Venus' thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. The greenhouse effect makes Venus roughly 700°F (390°C) hotter than it would be without a greenhouse effect.

larisa86 [58]

The survival rate is a measure of the fitness of each species. Option A is correct. Green beetles are more fit for the environment than brown beetles are.

<h3>What is fitness?</h3>

Fitness or Aptitude can be defined as the contribution of each genotype to the next generation.

Fitness is reflected by the phenotype that results in the survival, fertility, and capability of having a mate.

It is a way of measuring the individual ability to leave fertile offspring.

Aptitude must be significant to the natural selection act in its favor.

In the exposed example we can see the survival rate of two species.

The survival rate is telling us about the fitness of each species.

  • The green beetle increases its survival rate (fitness) each year
  • The brown beetle decreases its survival rate each year

These results lead us to believe that the Green beetles are more fit for the environment than brown beetles are. Option A is correct.

Pepsi [2]

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 cell feature is used by scientists to classify an unknown cell as prokaryotic or eukaryotic?
zhannawk [14.2K]

Answer:

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.

Explanation:

Hope this helps ;)
