Answer: grasshoppers produce sounds to attract mates or protect territory.
Explanation: Like their cricket cousins, grasshoppers produce sounds to attract mates or protect territory. Grasshoppers can be identified by their unique songs, which differ slightly from species to species. Grasshoppers stridulate by rubbing their wings together in the same manner as crickets.
Answer:
Are transferred completely from the valence shell of an element to the other
Explanation:
Basically, to form a chemical bond, you either transfer or you share. When you share, it is a case of covalent bonding which can be in several other forms. When there is a transfer, it is a case of ionic bonding.
The basic explanation for this is that while some atoms are electronically sufficient, some are electronically deficient. This means while some atoms are having an excess number of electrons, then some are having less number of electrons.
To satisfy both parties, there must be a transfer if electrons between the two parties. While the one with the excess numbers serves as the donor, the one with insufficient number of electrons serve as the acceptor
Answer:
Negative
Explanation:
For a solution to form, the change in Gibbs free energy must be negative for dissolving. When a solute dissolves in a saturated solution, ΔH(enthalpy change) is negative and ΔS(entropy change) is positive, giving rise to a large negative ΔG(change in gibbs free energy) and a very high solubility.
