But only those seeds that have just the right amount of moisture, light and humidity will germinate.
Scientists have since found that the tips of plant roots, in addition to sensing gravity, moisture, light, pressure, and hardness, can also sense volume, nitrogen, phosphorus, salt, various toxins, microbes, and chemical signals from neighboring plants.
Because relations between temperature and moisture, light and shade, change daily throughout the year, every region and locality on Earth in fact, every building site has its own climate, unlike any other.
Through kinetic experiments, the dependence of reaction rate on some key influencing factors (moisture, light intensity, initial contaminant concentration) has been studied, and kinetic models have been developed to aid the optimal reactor design.
In order to germinate at the right time, plants must be able to accurately sense and respond to a complex host of environmental factors -- moisture, light and temperature, just to name a few.
Synthetic fiber, the booklet said, though lacking the body and tensile strength of pure Caucasian, is not only cheaper and more durable, but also colorfast; protected from excessive moisture, light, and other agents of time, its subtle shades and natural tints will neither blend nor fade.
The success of Sitka spruce regeneration within gaps appears to depend on sufficient moisture and light to support regeneration and early growth, but not too much light to encourage the development of competing vegetation.
Hurricanes need warm tropical oceans, moisture, and light winds above them.
Propitious conditions include not just soil temperature and texture but also moisture and light.
Moisture, good light and a weekly dose of fertilizer are all that is needed.
Free-living protists, on the other hand, face short- or long-term changes in temperature, aquatic acidity, food supply, moisture, and light.
