What of the substance sucrose or water causes the formation of pollen tube?
Sucrose acts as a source of energy for the growing pollen tube, providing the necessary fuel for its elongation. Water is crucial for maintaining turgor pressure within the pollen tube, which helps it to push through the pistil tissues during growth. Both substances play essential roles in the formation and elongation of pollen tubes.
What is role of bacteria in the formation of limestone caves?
It has no directrole. Caves are formed in limestone primarily by slightly acid ground-water dissolving it. The acidity comes from the water falling as rain, absorbing carbon dioxide from the atmosphere. The result is the weak carbonic acid - natural soda-water in fact! If bacteria have any role at all it may be forming acids in the soil by decay of organic matter, to augment the carbonic acid, but this is aminor part. So essentially, bacteria play no part in cave development.
Which organisms play roles similar to organisms in water ecosystems?
Organisms in forest ecosystems, such as trees, plants, insects, and birds, play similar roles to organisms in water ecosystems. For example, trees provide shelter and food for animals, just like aquatic plants in water ecosystems. Insects and birds help with pollination and seed dispersal in forests, similar to their roles in water ecosystems.
Chemical and physical processes include the formation of clouds and precipitation burning food and the flow of running water.?
Chemical processes involve changes at the molecular level, such as combustion during burning food. Physical processes involve changes in the state or form of matter, like the flow of water and the formation of clouds through condensation and precipitation through the water cycle. Both types of processes play important roles in Earth's natural systems.
What does NOT play a role in magma formation?
One factor that does not play a role in magma formation is the Earth's rotation. Magma formation is primarily influenced by factors such as temperature, pressure, composition of the rock, and the presence of volatiles (such as water and gases) in the mantle.
What are the causes of expansion and contraction of water in soil formation?
Expansion of water in soil formation can be caused by freezing and thawing cycles, leading to frost wedging. Contraction of water can occur when water evaporates from the soil, resulting in shrinkage. Both expansion and contraction play important roles in shaping soil structure and contributing to the weathering of rocks.
Erosion and deposition play roles in the formation of what kind of rock?
Erosion and deposition play important roles in the formation of sedimentary rock. Erosion breaks down rocks into sediments which are then transported and deposited in layers. Over time, these sediments are compacted and cemented together to form sedimentary rocks.
What is the opening or crack in the cave called?
The opening or crack in a cave is commonly referred to as a "cave entrance." This entrance can vary in size and shape, allowing access to the interior of the cave. Depending on its geological formation, it may also be called a "sinkhole" or "cavern entrance." Such openings play a crucial role in the cave's ecosystem and airflow.
What controls where a cave forms?
Caves form in locations where there is soluble rock such as limestone, gypsum, or salt. Factors like the presence of water, chemical weathering, and time play a role in the dissolution of these rocks to create cave systems. Additionally, tectonic activity and local geology can impact the formation of caves in specific areas.

Is it need to play 6 hours continuously to get the water in shoal cave to become low tide?
No.

Which factor does not affect soil formation?
Soil formation is not affected by plate tectonics, as it is a geological process related to the movement of Earth's lithosphere. Other factors such as climate, vegetation, parent material, and time play major roles in soil formation.
How does this principal work in terms of cloud formation?
The principal of cloud formation involves the cooling of air, which reduces its capacity to hold moisture. When warm, moist air rises, it expands and cools, leading to condensation as the water vapor turns into tiny water droplets or ice crystals. These droplets cluster together to form clouds. Additionally, factors such as temperature, humidity, and atmospheric pressure play crucial roles in this process, influencing the type and formation of clouds.
