kinetic energy is needed by the molecules in order to escape from the surface.
All the water molecules in the liquid are moving randomly due to the presence of some energy in it. Some of the molecules have more kinetic energy due to absorption of heat energy from the surrounding environment.
Due to high kinetic energy, these molecules move enough to escape the surface of the liquid. This is called boiling point. This makes the liquid become gas so we can conclude that kinetic energy is needed by the molecules in order to escape from the surface.

The population of Bengal tigers can be monitored by tagging and counting of foot prints.
The method of conserving tigers is in-situ conservation.
<h3>What is population?</h3>
Population is the total number of organisms living in a particular area and interacting with their environment at specific time.
Endangered species are species of organisms that can easily be affected by predators and are at the point of extinction.
Therefore, population of Bengal tigers can be monitored by tagging and counting of foot prints.
The method of conserving tigers is in-situ conservation.

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.
You can see the location of the appendages on the segments more clearly on the ventral side of the crayfish.
