Organic deposits are rarely found in areas of extreme wetness or extreme cold.
true/ false
The correct answer for this question is False
Microbial degradation is aggressively destroying important cultural and environmental records that have been stored in archaeological deposits for millennia across the Arctic. Because it is not practicable to examine the many sites in this distant corner of the planet, new approaches for detecting and assessing potential degradation are urgently needed.
Organic-rich sedimentary rock deposits are collectively referred to as fossil fuels because they are made up of undamaged organic tissue of plants and animals preserved in depositional environments with low levels of free oxygen. Fossil fuels are the primary energy sources in the industrial world, and their unequal distribution in time (exclusively Phanerozoic) and space (more than half of proven petroleum reserves are in the Persian Gulf region of the Middle East) has a significant impact on global political and economic stability.

Compare phasic and tonic contraction in smooth muscles. what tissues and organs are associated with each?
As for comparison, phasic smooth muscle displays rhythmic contractile activity and is associated with gastrointestinal and urogenital systems. While, tonic smooth muscle is continuously contracted and is associated with the large arteries and veins.
Biology routinely distinguishes between smooth muscle tissues that are "tonic" (producing a slow, sustained isometric contraction) and those that are "phasic" (generating a fast transient isometric contraction).
Smooth muscle is divided into tonic and phasic subtypes, but there are some significant functional differences between these muscle types.
The phasic smooth muscles function as unitary muscles, with action potentials spreading from cell to cell, resulting in coordinated phasic contraction, as seen in gut peristalsis.
While,
Tonic smooth muscle behaves as multiple independent units, or motor units, with graded changes in membrane potential of each unit, i.e., without action potential propagation, resulting in graded changes in force (tone).

When do total lunar eclipses occur?(1 point) infrequently during the full moon infrequently during the full moon infrequently during the new moon infrequently during the new moon every month during the full moon every month during the full moon every month during the new moon
Lunar eclipses occur infrequently during the full moon. They do not occur during the new moon and do not occur every month.
Eclipses occur when the sun, moon and earth are perfectly aligned in a straight line. Depending on which body comes in the middle of the alignment, eclipse can be divided into solar and lunar eclipse.
A lunar eclipse occurs when the earth comes in between the sun and the moon in a straight line. Direct sunlight is blocked off by the earth, however, deflected light from the earth reaches the moon, giving it hues of red, brown and grey. It only occurs when the moon is at the lunar node (points where the moon crosses the earth's orbital plane). This rarely occurs because the orbital path of the moon around the earth is inclined at an angle of 5°, so it's not possible to see a lunar eclipse every month.
Lunar eclipse only happens when the moon is full because it is only during the full moon that the moon can be positioned behind the earth. One is more likely to see a solar eclipse during the new moon.
