Cells get energy by breaking down food molecules to release the stored chemical energy by a process called 'cellular respiration'.
During the process Oxygen is used to oxidize food, that oxidized food is known as glucose.

The property of polarity of the water and cohesion could be the actual responsible for the beading up of water on the surface of leaves.
What is cohesion?
Cohesion, also known as cohesive attraction or cohesive force, is the action or quality of like molecules sticking together and being attracted to one another (from the Latin cohaesi, "cohesion, unity"). The uneven distribution of surrounding electrons that results when molecules are close to one another creates electrical attraction, which can keep a small structure like a water drop in place. This attribute of a substance is caused by the shape and structure of its molecules. Surface tension is made possible by cohesion, resulting in a "solid-like" state that allows for the placement of light or low-density materials.
It turns out that the tendency of water molecules to attract one another, or the tendency of cohesion, is what causes surface tension. The "lowest energy state," or the state in which the atoms in the molecule are utilizing the least amount of energy, is when a water drop takes on its natural form. This condition of water occurs when a water molecule forms a sphere or ball and is encircled by other water molecules on all sides. On Earth, gravity flattens this perfect sphere into the form of a drop that we can perceive.

Answer:
ZZ species will take more number of crosses to produce a recessive offspring.
Explanation:
Here Z seems to be the dominant allele. A species having ZZ or homozygous dominant genotype shall not express the recessive phenotype until unless it has both recessive allele and this is not possible as of now or is dependent on the genotype of mating species and the number of generations of development.
If ZZ mates with WW, the offspring in F1 generation will have genotype ZW
However, if the offspring in the F1 generation are crossed then in next generation we could see organism with recessive phenotype i,e WW
ZW*ZW
ZZ, ZW, ZW, WW
While in case of organism having ZW type genotype, recessive phenotype will occur in the first generation cross with the ZW.
