How can a whole organism be preserved

Biology
2 answers:
Deffense [45]3 years ago
6 0

Answer:

Only dead organisms that are buried quickly or protected from decay can become fossils. Generally only the hard parts of organisms, such as wood, bones, shells, and teeth, become fossils. In rare cases, an entire organism may be preserved. In some types of fossils, only a replica of the original organism remains.

Organisms often preserved by carbonization include fish, leaves and the woody tissues of plants. permineralization or petrifaction takes place in porous materials such as bones, plants and shells.

how do volcanoes that form on a plate moves over hot spot in the mantle differ from volcanoes that form along convergent plate b
WINSTONCH [101]
A hot spot is here magma appears near to the surface. Imagine this, the crust is a plate, and the hotspot is a pencil, as the plate moves, you punch holes through the plate. This is the hotspot creating volcanoes as the crust moves. This is how hotspot volcanoes are created. The volcanoes that are created on boundaries are created from differences in the crust as it is created.

slamgirl [31]
Savannas can be found anywhere but must be located in a tropical climate to thrive.
The U.S.A. has a very moderate climate, and for the most part is the same overall. Thus, a savanna wouldn't be able to exist in the U.S.A without the tropical climate, which means all 12 months have temperatures around 64 degrees Fahrenheit, and there are only two seasons: wet and dry.
 As opposed to the U.S.A's Moderate Springs, Blazing summers, chilly falls, and cold winters (may fluctuate depending on the state), a savanna wouldn't be able to thrive.

Your answer is D: they exist only in the tropics.

Equilibrium is when the concentration is the same throughout an entire system. Explain how a cell reaches equilibrium in all thr
pantera1 [17]

It is pertinent to understand what hypertonic, hypotonic, and isotonic solution means before setting out to explain how a cell reaches equilibrium in each type of solution.

  • A hypertonic solution is one whose solute concentration is higher than that of the sap of a cell that is immersed in it.
  • A hypotonic solution is one with the same solute concentration as that of the sap of the cell immersed in it.
  • An isotonic solution has a lower solute concentration than that of the sap of the cell immersed in it.

In biological systems, water molecules move by osmosis from the region of higher water potential or lower concentration of solutes to the region of lower water potential or higher concentration of solute. An equilibrium is reached when there is no net movement of water between two sides. Hence;

  • A cell placed in a hypertonic solution will lose water to the surrounding solution until an equilibrium is reached. This means that such a cell will end up shrinking (wilting) or even dying due to loss of water from the cell sap.
  • A cell placed in a hypotonic solution will gain water from the surrounding solution until there is no net movement of water anymore. Such a cell might become turgid or even burst out its cell content.
  • A cell placed in an isotonic solution will neither gain nor lose water because the cell sap and the surrounding solution have equal solute concentrations.
