Answer:
Homeostatic control mechanisms have at least three interdependent components: a receptor, integrating center, and effector. ... The integrating center, generally a region of the brain called the hypothalamus, signals an effector (e.g. muscles or an organ ) to respond to the stimuli.
Explanation:
The right answer is A.
Osmosis is a phenomenon that considers only the exchanges between two liquid solutions of different concentrations in liquid phases separated by a semi-permeable wall. Osmosis is a phenomenon of diffusion of matter, demonstrated when solvent molecules pass through a semi-permeable membrane separating two solutions whose solute concentrations are different; the overall transfer of solvent is then from the least concentrated solution (hypotonic medium) to the most concentrated solution (hypertonic medium) to equilibrium (isotonic media).
The diffusion of matter, or chemical diffusion, refers to the natural tendency of a system to render uniform the chemical potential of each of the chemical species it contains.
Chemical diffusion is an irreversible transport phenomenon that tends to homogenize the composition of the medium.
Answer:
osmosis
Explanation:
the diffusion of water molecules from a area of high water concentration to an area of low water concentration,

Answer: The correct answer is -
D. Eukarya has similar evolutionary traits to archaea.
A phylogenetic tree (also known as evolutionary tree) is a diagrammatic representation (in the form of branch diagram) showing the evolutionary relationships among various organisms. It is constructed on the basis of similarities or differences in the genetic or physical characteristics of various species.
In the given phylogenetic tree, archaea domain shows more similarities to the domain eukarya as it has descended after the domain bacteria.
Thus, option D) is the right answer.
