Your answer is AB
People who have AB blood are considered "universal receivers" because they can take every single type of blood; their bodies can safety use A (because it already contains some A type blood), B (for the same reason), and O (because it is a neutral blood type).

Answer:
Nonliving characteristics include the fact that they are not cells, have no cytoplasm or cellular organelles, and carry out no metabolism on their own and therefore must replicate using the host cell's metabolic machinery. Viruses can infect animals, plants, and even other microorganisms.

Draining the oceans would show features such as mid-ocean ridges. These features would look like an extensive mountain range running down the spine of the ocean floor. This region marks the area where two oceanic tectonic plates are being pushed apart. Closer to land or the continents would be a gentle shelf that gradually deepens as one moves away from the coastline. This relatively gentle plain would then make a steep drop off down to an extensive plain stretching towards ocean ridges. The ocean floor also supports lone mountain structures, canyons and chasms.

Answer:
Animal cells tend to do best in an isotonic environment, plant cells tend to do best in
a hypotonic environment. This is demonstrated in the attached PDF.
Explanation:
A cell that does not have a rigid cell wall, such as a red blood cell, will swell and lyse (burst) when placed in a hypotonic solution, a process called cytolysis. Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die. In a hypertonic solution, a cell with a cell wall will lose water too. The plasma membrane pulls away from the cell wall as it shrivels, a process called plasmolysis.
