Answer:
C. sharp thorns
Explanation:
The plants stand still, are not very physically active, and seem to be on the menu of many animals. Precisely because they cannot win at the first sign of danger, one has developed other ways in which they can defend themselves from annoying and dangerous animals.
Some have developed long thorns that repel attackers. Some have poisons that are very strong and because of which animals do not think of trying to eat that plant, but the defense of some plants seems to be well thought out and ready for all forms of attack.
Answer:
it depends on the type of the cell.
Explanation:
Prokaryotic cells have internal folding of the cell membrane which are responsible for certain functions like respiration. These foldings increase the surface area.
Eukaryotic cells are compartmentalized which is a method to increase the surface area as there are lots of membranes inside the cell across which many processes take place.
In some cells like the ones making the lining of the villi in the small intestine there are folding in the outer cell membrane which also increases the surface area,
A cell must undergo<span> the </span>process<span> of meiosis in order to </span>have genetically different cells at the end of cell division<span>.</span>
Endothermy is just another word for the term "warm-blooded" and ectothermy is closest to the meaning of "cold-blooded." The obvious pros of endothermy is the ability to perform more activities within a larger range of temperatures. For example, a human would be able to walk around in 100 degree weather Fahrenheit. They would probably be sweating a lot to maintain body temperature and would require lots of water, but they could do it. In contrast, a Lizard would most likely be forced to stay in the shade under a rock or another place as they have no system for maintaining their body temperature, and thus would have to wait until the environmental temperature cooled down before they could find food or move around. The cons of endothermy is it requires a lot more energy for an organism to maintain homeostasis, which is also a pro of ectothermy as lizards and similar ectothermic organisms can utilize more of their energy to d food or move around. Hope this helps!
