Primarily, it detects peptidoglycan, which is present in a thick layer in Gram-positive bacteria. ... In Gram-positive bacteria, the cell wall is thick (15-80 nanometers), and consists of several layers of peptidoglycan. They lack the outer membrane envelope found in Gram-negative bacteria.

Answer:
The effort put by scientist and sailors about earth is that they keep on going round the earth and putting their lives in danger and some even give their lives.
Explanation:
......
Reverse faults are exactly the opposite of normal faults. If the hanging wall rises relative to the footwall you have a reverse fault. Reverse faults occur in areas undergoing compression. If you imagine undoing the motion of a reverse fault, you will undo the compression and thus lengthen the horizontal distance between two points on either side of the fault.
if you stood on the fault plane the block on the right would be under your feet. this is thus the footwall. The tan sandstone has been pushed up and over itself. This offset of the hanging wall indicates that this is a reverse fault.
Earth's long-term warming trend can be seen in this visualization of NASA's global temperature record, which shows how the planet's temperatures are changing over time, compared to a baseline average from 1951 to 1980. The record is shown as a running five-year average.
