A population of squirrels is preyed on by small hawks at maturity. the smaller adult squirrels can escape into burrows. the larger adult squirrels can fight off the hawks. after several generations, the squirrels in the area tend to be very small or very large. this is an example of disruptive selection. In disruptive selection, the extreme traits i.e., very small and very large sizes are favoured over intermediate trait i.e., average size.
Answer:
<u>Cilia</u>
Explanation:
Cilia and flagellum are made up of microtubules.
Cytoskeletal filaments are structures which allow movement. In cilia and flagella, the cytoskeletal filaments are present in the form of microtubules and the primary work of these structures is to facilitate in movement.
Cilia is also present in mammals to facilitate the movement of fluids in cells.
Structurally, there is no difference between cilia and flagella. The only difference between cilia and flagella is in their lengths.
Spiders do not have muscles for extending the legs at these joints. Spiders, like most creatures, desiccate upon death, losing their waters, explaining why spider legs curl up upon death.
The right option is Capsid
A capsid is a protein coat that
encloses the nucleic acid (RNA, DNA etc.) of a virus particle. Capsids are in different
shapes and the common ones are icosahedral, prolate, and helical. The main role
of the capsid is to protect the virus by ensuring that the nucleic acid inside
of it is safe.
