A Venus flytrap closes around a small insect. Which life characteristic does this illustrate? A. reproduction B. response to sti
Mnenie [13.5K]
The answer is B: Response to stimuli
what response to stimuli means is that the organism reacts to something around it
the venus flytrap wouldn't just randomly close for no reason
it had to sense the fly, and react by closing.

it's not permeability because permeability means allowing things to pass through like soaking up water
unless your teacher is referring to absorbing the nutrients of the dead fly after it's been killed
but I don't think that's what this question is about
:)

Pick one of anna's illnesses and explain all of the ways the illness affected three different body systems.
Rudik [331]
Heart disease affects the cardiovascular system by plaque building up on the artery walls narrowing them making it harder for blood to flow through which could lead to heart attack or probably stroke if the plaque blocks it entirely or maybe almost entirely.

Heart disease may also affect our nervous system for there is higher risk to stroke and it is due to limited flow of blood to the brain and may lead to heart failure which may happen with heart disease that puts the stress on the brain and nerves.

The digestive system is affected by heart disease that causes the system to not get the right amount of oxygen and the nutrients that it needs from the blood.
