Answer: Asthenosphere.
The rising hot rock comes in contact with cold rocks near the surface of Earth where it gives off its heat, cools, and sinks again. Most of the rock in the mantle moves in this broad cyclic flow, indicated by the arrows in the figure. This zone, where rock is soft enough to flow, is called the asthenosphere.
Explanation:
The asthenosphere is the highly viscous, mechanically weak and ductile region of the upper mantle of the Earth. It lies below the lithosphere, at depths between approximately 80 and 200 km below the surface.
The asthenosphere is a layer (zone) of Earth's mantle lying beneath the lithosphere. It is a layer of solid rock that has so much pressure and heat the rocks can flow like a liquid.
The asthenosphere is also known as the "low velocity" zone of the mantle because seismic waves slow down as they pass through it. This property tells us that the asthenosphere is composed of partially molten rock slush like material consisting of solid particles with liquid occupying spaces in between.
Answer: A.
Nucleated red blood cell is less mature than a mature erythrocyte. They
are erythroid precursors that have apoptotic nucleus, the last nucleated stage of
red blood cell production to contain a defined, intact nucleus before the
erythrocyte losses its nucleus.
Moreover, they are confined
to the bone marrow, in the peripheral blood in newborns and in uncompensated
hemolytic anemia.
The correct answer is C) the fluorescent cells can help track the movement of cells.
Explanation:
In the last years, geneticists and scientists created animals that glow in the dark by inserting a Green Fluorescent Protein or GFP gene found in some species of jellyfish. This protein was used in animals such as rabbits, rats, and even chickens. One of the key reasons for this is that by inserting fluorescence scientists can better observe the development and movement of cells. This includes analyzing cells reproduction and growing in embryos of "glowing" animals or inserting the protein in specific cells or organs in an organism to observe how these change or move. Thus, the purpose of studying fluorescent rabbits is that "the fluorescent cells can help track the movement of cells".
