Answer:
<em>The correct option is B) a mushroom appearing wet in the rain.</em>
Explanation:
A response is generated when a living body detects a change or event as a signal or a stimulus.
In the option A, the Sun acts as a stimulus. The response is the tree turning its leaves.
In the option C, touch is the stimulus. The contraction of the protozoa is the response.
In the option D, the smell of food is the stimulus. Rumbling of the stomach is the response.
<em>In the Option B, no response is carried out by the mushroom. Hence option B does not show an action or response.</em>
Biology > Cell biology > Passive transport
There are different types of transport in the cell that can be classified into two groups: passive transport (which does not require energy) and active transport (which requires energy because it goes against the concentration gradient).
Diffusion is a type of passive transport and it does not require energy, it can be divided into simple diffusion (molecules pass through the membrane without the help of any channel) and facilitated diffusion (molecules pass through the membrane with the help of a protein channel).
Facilitated diffusion will transport certain molecules and simple diffusion others. Larger, polar and charged molecules will need help to cross the membrane, so they will do so by facilitated diffusion. Therefore, the answer is D.
The answer is C.
Non-renewable resources are resources such as, coal, natural gas and oil, which is usually harmful to the environment and causes pollution. Renewable resources are resources are energy sources such as solar energy, wind, ocean currents etc., these energy sources have a positive effect on the environment.
Hope this helps :)
