The most important property of the cell membrane is its selective permeability: some substances can pass through it freely, but others cannot. Small and non polar (hydrophobic) molecules can freely pass through the membrane, but charged ions and large molecules such as proteins and sugars are barred passage.
Answer:
Well, I am not sure whether is my answer correct, but hopefully it helps.
So for A there is no force acting on it this it remain in a rectangular shape but as for B there is a force acting on it which cause it to converge/compress and thus it deformed.
The correct answer is epithelial tissue.
This is because epithelial tissues line the outer surfaces of the blood vessels throughout the body. The blood vessels are the part of the circulatory system and their function is to transport blood throughout the human body inclusing the received or given substances.
Answer:
Mass movement
Explanation:
Mass movement refers to the synchronized and sustained contraction of the circular muscles of the colon. It does not follow the pattern of peristaltic waves.
The mass movement occurs immediately after the intake of a meal and serves to force the colonic content to move into the rectum. The result is the stimulation of defecation reflex.
The mass movement is triggered by overdistension of the colonic segment and/or gastrocolic reflex.
