Answer:
endotherm
Explanation:
Endothermic animals raise body temperature and keep it constant from internal mechanisms, that is, the animal's own metabolism can control its temperature. Ectothermal animals are not able to regulate body temperature with internal mechanisms, so they need external heat sources to raise and maintain their constant body temperature. These animals get heat from the environment (outdoors), usually by exposure to the sun or in contact with hot surfaces such as rocks.
C is the answer.
Metamorphic rocks is when a rock changes under time and lots of pressure.
Sedimentary is rocks made of sediment.
Igneous rocks are rocks that are made of magma.
Knowing this, C is closest to the definition of metamorphic rocks.
When neurons are loaded with fura-2, an increase in cytoplasmic fluorescence is expected when the neuron is depolarized. Fura-2 is a calcium indicator dye that is often used to measure changes in intracellular calcium concentration. When neurons are depolarized, there is an influx of calcium into the cell, which results in an increase in fluorescence.
<h3>
Explain Cytoplasmic fluorescence?</h3>
Cytoplasmic fluorescence is a type of fluorescence that occurs in the cytoplasm of cells. This fluorescence is caused by the presence of fluorescent molecules in the cytoplasm, which absorb and emit light at specific wavelengths. The most common fluorescent molecule in the cytoplasm is green fluorescent protein (GFP), which emits green light when excited by ultraviolet (UV) light. Cytoplasmic fluorescence is used in many biological applications, including cell imaging, protein localization, and gene expression analysis.

It would be in a hypotonic solution, so the fresh water would move in to the cell and cause the cell to burst.
