Answer:
c. Cells contain tiny organisms within them.
The gecko's feet contain molecules that are attracted to the molecules on the surface.
Geckos are lizards which belongs to reptile group. They are found in warm climatic regions of the world. Geckos and some other animals can climb smooth surfaces because of presence of Van der waal forces of attraction between the molecules of gecko's feet with molecules of the surface. The force of attraction is generated due to fluctuations or differences in charge present in molecules of feet and that of surface. The charge fluctuations generally comes into sync and generate attractive force.
<h3>What are the features of Geckos ?</h3>
Most geckos are small, soft-skinned reptiles that are often nocturnal in behaviour. A small, robust body, a big head, and often well-developed limbs are other features they have. Each limb's tips are frequently fitted with digits that have adhesive pads.
- The gecko possesses a variety of adaptive traits that help it avoid or confound predators. If a predator catches the gecko by the tail, the tail can be cut. One of the most well-known characteristics of the species is this. Some geckos may also alter their colour to better fit their surroundings.

Answer:
The restriction endonucleases in bacteria (b) they provide a defense mechanism against infection by viruses
Explanation:
The restriction endonucleases is a protein that is produced by the bacterias that interacts with the DNA of them and gives protection to the bacterial cell by defending against viruses.
Is important to remember that viruses go into different organisms just with a copy of DNA that wants to replicate inside of them creating more and more copies until it breaks the hosting cell and this is how the infection spreads. This protein restricts (that's the reason of its name) or stops the replication stage of the virus DNA by cutting it into many pieces stopping in this way the spread of the infection and the death of the bacteria.
The cell membrane is in control of what materials go in and out of the cell so the correct answer is 4. Regulates diffusion.

Each of the 3 type of finch consume different food sources. if two of the food sources are gone, the other two finch’s won’t be able to eat and survive. the entire population of these 2 types may become extinct; only the last specie will survive.
in conclusion, the finch population will decrease.
hope this helps!
