Answer:
Can I see the graph or the other options??
Explanation:
Answer: The correct options that apply to the food web are-
- Food webs are a group of connected food chains.
- Arrows in a food web go from the organism that is being eaten to the organism that is eating it.
- Arrows in a food web represent the flow of energy in a food web.
- Food webs show all of the eating patterns in an ecosystem.
A food web is an interconnected network of different food chains representing flow of energy and matter within an ecosystem. The different arrows in a food chain represent organisms being eaten by other organisms, thereby representing flow of energy. It also represents that an animal can consume more than one food type.
Answer:
Galaxies rotate in their center with parts of galaxies that are far away from centre.
Explanation:
Galaxies move throughout the space. It rotates around its center with the portions of galaxy that are far from the center and moves relatively slowly from other objects near the center.
Because of the Big bang explosion because of which the Universe have expanded, galaxies are going away from other galaxies. The galaxy cluster also moves around the cluster center.
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!
