Bacterial responses to antibiotics are concentration-dependent. At high concentrations, antibiotics exhibit antimicrobial activities on susceptible cells, while subinhibitory concentrations induce diverse biological responses in bacteria.
Absorb more thermal energy, and the rough surface will prevent it to reflect efficiently.
Since the
speed of many physiological processes in marine organisms is determined by the
temperature, the first consequence of the changes in the conditions of the
medium becomes offset the timing of seasonal events, such as the timing of
spawning fish. There have also offset migration routes and spawning areas. So,
as a result of warming in the Sea of Japan, spawning navaga shifted to an
earlier date, because of the reduction of the area of "cold spots"
in the eastern Bering Sea shelf feeding migration of pollock, halibut and crab
are lengthened, but because of the temperature rise to the east of Japan,
spawning saury expanding. These changes significantly affect the success of
reproduction, resulting in changes populations of their fishery.
<span>During a micro-sleep, you are likely to have a blank stare, sudden shake of the body, head snapping and you are not able to recall a last minute.
The duration of micro-sleep are from 1 second to 30 second.
It can happen to anyone and at any time of the day. there are many reason of micro-sleep and it is said to be dangerous, especially when you are driving.

The membrane is selectively permeable because substances do not cross it indiscriminately. Some molecules, such as hydrocarbons and oxygen can cross the membrane. Many large molecules (such as glucose and other sugars) cannot. Water can pass through between the lipids.
