Answer:

a scrape being healed

Explanation:

cell reproduction is the process by which cells divide to form new  cells. each time a cell  divides it makes a copy of all its chromosomes, which are tightly coiled strands of DNA, the genetic material that holds the instructions for all life, and sends an identical copy to the new cell that is created.

Answer:

Explanation:

Habitat Grasslands  Common Nighthawks nest in both rural and urban habitats including coastal sand dunes and beaches, logged forest, recently burned forest, woodland clearings, prairies, plains, sagebrush, grasslands, open forests, and rock outcrops. They also nest on flat gravel rooftops, though less often as gravel roofs are being replaced by smooth, rubberized roofs that provide an unsuitable surface. During migration, Common Nighthawks stop in farmlands, river valleys, marshes, coastal dunes, and open woodlands. Their South American wintering habitat is not well known.

Food

Food Insects Common Nighthawks eat flying insects almost exclusively. The Common Nighthawk hunts on the wing at dawn and dusk, opening its tiny beak to reveal a cavernous mouth well suited for snapping up flying insects. It often takes advantage of clouds of insects attracted to streetlamps, stadium lights, and other bright lights. Nighthawks eat queen ants, wasps, beetles, caddisflies, moths, bugs, mayflies, flies, crickets, grasshoppers, and other insects. They may also eat a small amount of vegetation. Though they forage in low light, they seem to locate prey by sight, possibly with the help of a structure in their eyes that reflects light back to the retina to improve their night vision. They occasionally forage during the day in stormy weather, but seem to never forage at night. Common Nighthawks may forage near the ground or water, or more than 500 feet into the sky.

Scientists discovered that the inner core of Earth is a solid. Explain what evidence supports this thinking. Be sure to include
Anni [7]

Explanation:

From the studies done on seismic elastic waves, it has been discovered that the innermost core of the earth is a solid concentric layer. Seismic P and S waves can be propagated through solids but the s-waves are cut off in contact with a liquid medium. This is because s-waves are shear waves and fluids do not shear.

  • At the outer core, the s waves is cutoff and it reappears in the region of the inner core.
  • This shows that the inner core is solid.
  • The inner core is made up of iron and nickel with some other siderophiles.
  • At the inner core, the pressure is very great. Pressure here is about 350gigapascal.
  • This huge pressure compresses matter into solids despite the very high temperature.
  • Also, during the differentiation of the earth, the heavier minerals moves downward to the core due to their density. Metals in the core have density of about 13g/cm³.
