D - the theory of natural selection states that the population will be narrowed as "less fit" organisms die and "more fit" organisms survive, passing on their beneficial genes to offspring. Therefore, more organisms are born than can survive.

The correct answer is D. More organism are born than can survive

Explanation:

Darwin's Natural Selection Theory explains evolution takes place as there are differences between individuals that make only some of them survive as changes in environmental conditions make certain traits to prevail over others. This theory was created based on Darwin's observations in different ecosystems in which he found there were slight differences between organisms of the same species and also that more organisms are born than can survive, due to this observation Darwin found only those that are best adapted will survive and reproduce which explains natural selection. Thus, the observation Darwin made as he developed his theory of Natural Selection was "more organism are born than can survive".

jenyasd209 [6]

Answer:

a. ​food pellet

Explanation:

In classical conditioning, an unconditioned stimulus is the stimulus that naturally elicits an unconditioned response. The unconditioned stimulus is usually paired with a neutral stimulus, and after pairing with a neutral stimulus, the neutral stimulus becomes a conditioned stimulus that elicits a conditioned response alone.

In the experiment described above in the question, <em>the unconditioned stimulus is the food pellet,</em> which naturally elicits the response of the rat to wait at the far left corner of the cage. The neutral stimulus which is paired with the food pellet is the vanilla scent, which now becomes the conditioned response, when paired alone.

  • This is the region of the Arctic and Antarctic circle.
  • This region receives diffused solar radiation from the sun.
  • This is why they rarely warm up.

Compare the wind speeds of the edge of a hurricane on earth and the edge of the great red spot on jupiter what is your conclusio
Illusion [34]

Answer:

Jupiter is approximately 318 times bigger than the earth. So, it is expected that its hurricanes would be very massive as well.

Explanation:

A hurricane is a tropical cyclone, a storm with a very violent wind. It is labeled a cyclone because of its cyclic nature.

The Great Red Spot of Jupiter is a giant storm about twice as large as Earth, which in its southern hemisphere orbits the globe. This at least twice the speed of the most dangerous and most destructive hurricanes on Earth, which can produce wind speeds of approximately 280 km/h.

So it means that if there were to be a great red 'jupiterian' spot on earth it would blow the earth away.
