Darwin studied actual birds on the Galapagos Islands instead of using a simulation, as you did in this lab. Studying natural sel
Elza [17]
Darwin lived in a time where natural selection was a strange theory among scientists and researchers. This was especially true when other researcher Lamarck argued that organisms passed on helpful traits to their offspring, that they magically could form a new trait to adapt to their environment and then pass it onto their offspring. For example, if a giraffe was too short to reach food, it would grow a larger neck in its lifetime and then pass that trait onto its offspring. Darwin argued that, through the process of survival of the fittest, that short giraffe would die off and never receive the chance to pass on its shortness to future populations. Thus, taller giraffes would survive— they can reach food, shorter giraffes can’t— and the short genes would disappear. The fact that Darwin was introducing a new theory that nobody was used to at the time was peculiar, so he had few people on his side until long after his observations.
Another problem Darwin had was the lack of technology. To travel, Darwin would have to use boats to reach far away places, and of course, this took time.
The final problem Darwin had was the extra time it took for evolution, a process that can take up to millions of years. Evolution didn’t occur over night— it took time for Darwin to conduct experiments, observe, conduct them again, come to a conclusion, and so on.
Hope this helped a little!

Which of the following structures would you expect to find in a single-celled organism?. A) internal organs. . B) legs and feet.
Karo-lina-s [1.5K]

The correct answer is:

C) outer covering

The structure that you should expect to find in a single celled organism is : C. outer covering.Single celled organism still hasn't developed a complex body structure, so it definitely won't have legs, internal organs, or brain.

Explanation:

None of the other answers can happen due to the combined solutions disability to reach the center of the organism, smaller cells in higher numbers are more effective as they can group commonly yet all receive the right amounts of nutrients for its need. multicellular organisms, such as humans can have the other answers in them as cells group collectively to make skin, muscles, and organs. it also provides the body to grow larger.

Microscopic plants called algae grow inside the top layer of sea ice in the Antarctic if enough sunlight reaches that layer of i
MrRa [10]

Answer:

The correct answer is: (A).

Explanation:

  • In the question, it is mentioned that the algae can grow under the conditions of "enough sunlight" and "enough nutrients".
  • Sunlight reaches the algae, by first falling on the surface made up of ice and snow and then refracting from there into the top layer of the ice where the algae grows.
  • However, the capability of both snow and ice to reflect sunlight is far more than that of refracting sunlight.
  • Therefore, the amount of light received by the algae is similar in absence or presence of the layer of snow on the top layer of ice.
  • However, on deposition of snow on the layer of the ice, the weight of the ice increases and it sinks below into sea water.
  • This allows more nutrient rich sea water to percolate into the ice and reach the algae.
  • The algae receive more nutrients from the sea water and hence is capable undergoing better metabolism and growth.
  • Hence, more algae are produced under such a situation.
