Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out . All cells have cell membranes, and the membranes are flexible. So animal cells can have various shapes, but plant cells only have the shapes of their cell walls.
The dependent variable is the one that changes throughout the experiment based off of the independent variable
Hello. Your question is incomplete. However, I managed to find a question exactly like yours on the internet and managed to realize that you forgot to say that your question asks you to give an example of the statement presented above.
Answer:
A major disturbance from which the ecosystem was able to recover completely was the disease that almost wiped out all of Ireland's potato in 1840.
Explanation:
You may have heard of the Irish Potato Famine, which was a time when the Irish population lived very difficult days, after an illness that almost decimated the country's potato plantations.
The potato was the main source of food for the Irish, but in 1840, a fungus called Phytophthora infestans, managed to infect almost all potato plantations in the country, preventing the potato from being harvested and could be consumed. This created major economic and social problems in Ireland, as people suffered from hunger, poverty and the diseases that arose, which caused many Irish people to immigrate to other countries, or to die.
The fungus plagued the ecosystem for years and only started to decrease in intensity in 1850, once the ecosystem started to recover. Currently, although the pest still exists, the Irish ecosystem is completely recovered and the pest is controlled and is unable to make such an impact.
