The "plasma membrane" (a.k.a Cell surface membrane) is a fragile and partially permeable membrane that holds the cell together and controls what substances get in and out
I think the answer is C. Sciences that focus on human behavior and society
Answer: Option B) positive; decrease
High body temperature in mammals reflexively causes a change in blood flow and sweating, which act to reduce the temperature. This is a positive feedback loop because response to the signal results in a decrease of that signal.
Explanation:
A positive feedback loop occurs when an organism responds to disturbing changes in its environment by adjusting its internal body processes to cope with the changes should it continue.
Thus, the body switches on vasodilation and sweating through a positive feedback loop to decrease its high temperature caused by the environment
Answer:
The correct answer is option B. membrane budding requires transient breakages in the bilayer membrane.
Explanation:
Phospholipid bilayer consists of two layers of the phospholipids with a hydrophilic head externally and hydrophobic tail internally in each phospholipid molecule. It is the surrounding membrane that encloses the cell cytoplasm and contents.
Internally phospholipid bilayer are hydrophobic due to hydrophobic in nature. It acts as a barrier that separates the cell from the external environment. It is possible to spontaneous formation of bilayers is due to to the chemical properties.
Thus, the correct answer is option B.
Either A or D I’m not 100% sure but it’s the only thing that makes since
