Plants make seeds that can grow into new plants, but if the seeds just fall to the ground under the parent plant, they might not get enough sun, water or nutrients from the soil. Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire.

Plz help me What is the role of the major reservoirs in the water cycle

SCORPION-xisa [38]

Answer:

water inhabits reservoirs within the cycle, such as ponds, oceans, or the atmosphere. The molecules move between these reservoirs by certain processes, including condensation and precipitation. ... If climate cools and glaciers and ice caps grow, there is less water for the oceans and sea level will fall.

Pea contains only 0.25% phenylethyl alcohol because high concentrations inhibit both gram-positive and gram-negative organisms.

sdas [7]

If the alcohol concentration in PEA agar was increased, it would inhibit both Gram - and Gram + bacteria by breaking down membrane absorbency barrier, tolerating influx of substances that are generally blocked and leakage of cellular potassium. High alcohol concentrations would lead to disruption or halting of DNA synthesis in both Gram + and Gram - bacteria

What molecules need to travel through ATP synthase to help it create ATP?

Anna [14]

Answer

Hydrogen ion movement form ATP in ATP synthase .

Explanation:

ATP synthase is present in mitochondrial membrane when pass hydrogen ion in to lumen of mitochondria and due to proton gradient generate ATP molecule with pass of hydrogen ion into lumen ATP is formed from ADP and inorganic phosphorous molecule . Passing of three hydrogen io generate one ATP molecule .So movement of hydrogen ion is directly related to ATP synthases.

Identify each event as the result of mechanical weathering or chemical weathering.

kow [346]

<h3>The following events are identified as chemical weathering:</h3>

The minerals in a marble statue react with water to form acids and pores in the structure.
The rocks in a region are streaked orange after being exposed to repeated rains.

Reason:

When the weathering process occurs due to chemical reaction, then it is considered as chemical weathering.

In the first case, minerals of marble statue are reacting with water to cause weathering. In the second case, due to the acidificaion reaction, the change of the color has happened after exposure to the repeated rains.

<h3>The following events are identified as Mechanical weathering:</h3>

A piece of rock crumbles after being constantly thrashed by strong waves.

Industrial runoff forms cracks in a rocky structure in its path.

Reason:

When the rock is broken into simple pieces without any chemical reaction it is considered as mechanical weathering.

In the first cause, due to the abrasion caused by the strong waves, weathering has happened, in the second case industrial run off may be of varying temperature and thus may cause heating or cooling of the rock and causes weathering.

Identify the events that lead to a lake-effect snow.

Pavel [41]

Lake Effect snow occurs when cold air, often originating from Canada, moves across the open waters of the Great Lakes. As the cold air passes over the unfrozen and relatively warm waters of the Great Lakes, warmth and moisture are transferred into the lowest portion of the atmosphere. The air rises, clouds form and grow into narrow band that produces 2 to 3 inches of snow per hour or more.

<h3>Which are the key factors in lake snow affect?</h3>

Wind direction is a key component in determining which areas will receive lake effect snow. Heavy snow may be falling in one location, while the sun may be shining just a mile or two away in either direction.

The physical geography of the land and water is also important.
