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.

They had no natural predators, so they spread quickly and ate the farmers crops and also made the bilby an endangered species.
Most commonly, jello or any kind of gelatinous material is used when making a cytoplasm, while a nucleus is represented well with a plum.
The best answer is C.Ribosomes are cell organelles or structures that make protein. Ribosomes are found floating in the cytoplasm or attached to the endoplasmic reticulum of the cell.The location of the ribosome will determine what kind of protein it makes. If the ribosome is attached to the endoplasmic reticulum then it will make protein for usage within the cell or outside the cell. If found freely floating in the cytoplasm, then it will make protein that will be used only within the cell and not outside.
Answer:
El Niño impacts weather systems around the globe, triggering predictable disruptions in temperature, rainfall and winds. La Niña is the opposite – a cooling phase of ENSO that tends to have global climate impacts opposite to those of it. El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.
