Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components. Both types of membranes have a specialized structure that facilitates their gatekeeping function.
Answer:
all of the ones who eat the producer
Explanation:
The correct answer is C4 plants.
A plant that cycles carbon dioxide into four-carbon sugar components to get into the Calvin cycle is known as a C4 plant. These plants are very effective in dry, hot climates and produce ample energy. Various foods one consumes are C4 plants like pineapple, corn, and sugar cane.
In the C4 plants, at the start carbon fixation occurs in the mesophyll cells and the Calvin cycle occurs in the bundle-sheath cells. The PEP carboxylase combines with an incoming molecule of carbon dioxide to the three carbon-molecule PEP, generating a four carbon molecule, that is, oxaloacetate.
The answer is B: moist and hot with low density
Let's go back to "Darwin's" evolution theory. mice can be smarter than the average hawk, they are fast, have underground protection from cold,heat, rain,ECT..and they scavenge during p.m. hours, not all hawks are nocturnal, that's why owls are nocturnal. This cycle ensures enough food source for all predators. A hawk can consume at least 6 mice per day/night. rodents are natural prey for all preditors., even coyote. hope this helps, plus mice reproduce quickly compared to preditors.
hope this helps..
