There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. Dispersal involves the letting go or detachment of a diaspore from the main parent plant.
Fruits and seeds dispersal is the process whereby fruits and seeds are scattered from their origin. The various ways by which fruit and seed are dispersed are known as agents of seed and fruit dispersal.

Answer:
Scientific models are used to explain and predict the behaviour of real objects or systems and are used in a variety of scientific disciplines, ranging from physics and chemistry to ecology and the Earth sciences.
Explanation:
Answer:
d. it has a high boiling point
Explanation:
all ionic compounds with ionic bonds have high boiling points
Answer:
The new pressure of the gas comes out to be 400 KPa.
Explanation:
Initial volume of gas = V = 
Initial pressure of gas = P = 120 KPa
Final volume of gas = V' = 
Assuming temperature to be kept constant.
Assuming final pressure of the gas to be P' KPa
New pressure of gas = 400 KPa
Answer:
424 mol
Explanation:
Step 1: Given data
Number of atoms of Neon: 2.55 × 10²⁶ atoms
Step 2: Calculate the number of moles corresponding to 2.55 × 10²⁶ atoms of Neon
In order to convert atoms into moles, we need a conversion factor, which is Avogadro's number: there are 6.02 × 10²³ atoms of Neon in 1 mole of atoms of Neon.
2.55 × 10²⁶ atoms × (1 mol/6.02 × 10²³ atoms) = 424 mol
