Answer:
<u>Option- </u> Passive transport.
- The movement or transport of medium across an area or membrane on the basis of there concentration is termed to be the main mechanism for providing all the vital resources for the cell and tissue survival inside the body.
Explanation:
- Osmosis involves the movement of water molecules across a cell membrane. Diffusion involves the movement of substances other than water across a cell membrane. In both of these processes, substances move from an area of high concentration to an area of low concentration. Thus, both diffusion and osmosis are forms of <u>Passive transport.</u>
Answer:
The correct option is trial and error learned behavior
Explanation:
A trial and error learned behavior is a type of behavior in which an organism attempts to or tries something new which makes it (the organism) accept the reality of that thing or situation. This means that if the attempt is successful or pleasurable, the organism will attempt it again and if it's not, the organism will avoid that thing.
This is what was described in the question with the bird trying to eat the caterpillar but found it unpleasurable which made it to start avoiding it afterwards.
A DNA or good molecule needs protein synthesis because without it it would not be able to function properly!
