The right option is; Hooke
Robert Hooke was an English scientist that first recognized the cell as the universal unit of life. In 1665, Robert Hooke observed honeycomb-like structure when he viewed very tiny slices of cork using a coarse compound microscope. He called the structures cells but he did not know their actual structure and function.
The steps are:
1-The phage binds to a bacterial surface.
2-Phage injects viral DNA in host bacterial cell.
3-Host DNA hydrolyses in pieces.
4-Phage DNA is now replicated and new phage coat proteins are synthesized.
5-The bacterial DNA is surrounded by phage coat protein.
6-Host bacterial cell lyses.
7-Bacterial DNA is injected in a bacterium by the phage.
8-Bacterial DNA integrates into the new bacterial host chromosome.
Answer:
The mouse and shrew bones were common to all three owls so they were not useful in identifying environments. The gopher bones were unique to the great grey owl of Alaska. Gophers are rodents that are successful in areas with soft soil and lots of grass, so the gopher and this owl would be found in the meadows and evergreen forests of Alaska. The bat was unique to the barking owl of Australia. The bat would be found in woodland habitats where there are many trees the bat can hang from. The gull bones were unique to the short-eared owl of Cuba. Gulls are wetland birds, so the gull and this owl would be found in marshes and coastal areas.
True because excretory is like sweat and you sweat through your skin- more specifically the pores in your skin
