Answer:
In biology, osmosis is defined as the net movement of water molecules through a semipermeable membrane (e.g. cell membrane) from an area of higher to an area of lower water potential. Other definitions of osmosis are as follows:
The process of a solvent diffusing through a semipermeable membrane from an area of low solute concentration to an area of high solute concentration
The tendency of water to flow from a hypotonic solution (low concentration of dissolved substances) to hypertonic solution (higher concentration of dissolved substances) across a semipermeable membrane
In chemistry, osmosis is defined similarly. It is the passage of a pure solvent from a solution of lesser to one of greater concentration of solutes when the two solutions are separated by a membrane that selectively prevents the passage of solute molecules while allows the solvent molecules to pass through.

Answer:
Option (A).
Explanation:
Evolution may be defined as the change in the characteristics of a species over several generation with time. Natural selection acts as a main drivinf force for the evolution.
The drought of 1977 is responsible for the species evolution. The species is larger in this case (as mentioned in the question) and the species has deeper beaks over time. The birds have relatively large and deep beaks because they can easily crack the food.
Thus, the correct answer is option (A).
A describes a gymnosperm.
B describes any type of plant.
C is too vague to even describe a plant.
D (the correct answer) describes an angiosperm (flowering plant). After double fertilization, angiosperms form a fruit over the ovulary of the plant, where the seeds are located.
Its A
The electron cloud model consisted of a dense nucleus surrounded by a cloud of electrons like a fan. Hope this helps.<span>

Instructions from characteristics which are passed from the
parent to the offspring are called genes. Genes are made of complex molecules
of DNA. Each parent also donates chromosomes to their offspring. Each offspring
will get half of their genes from each parent and they will therefore have the aspect
of the two parents.
