Answer:
ok so
Explanation:
The role is
The Excretory system is responsible for the elimination of wastes produced by homeostasis.
The main structures are
The kidneys, large intestine, liver, skin, and lungs. They are part of the urinary system, which also includes the ureters, bladder, and urethra.
Maintaining homeostasis
Excretion is the process of removing wastes and excess water from the body. It is one of the major ways the body maintains homeostasis. Organs of excretion make up the excretory system. ... The kidneys maintain homeostasis by controlling the amount of water, ions, and other substances in the blood.
I think the answer could be B
Answer: Evolutionary
Explanation:
Evolution of the male and female reproductive organs is necessary for the advancement of mating strategies that range from simple to complex living beings. This is a kind of adaptation those which have phenotypic characteristics favourable to attract the mates will reproduce the offspring. These traits will be passed on to the progeny and evolution of the species will take place.
Initially, in terms of tonicity, the solution in side A with respect to that in side B is isotonic.
- A solution is considered to be isotonic if it possesses the same osmolarity, or level of solute concentration, as another solution. When these two solutions are placed on either side of a membrane that is only partially permeable to water, water will flow in an equal amount from one solution into the other. The result is that there is no water flow at all between the two solutions, despite the fact that water is travelling in both directions.
- A solution is considered hypotonic when it has a lower level of solute concentration in comparison to another solution.
- A solution is considered hypertonic when it has higher osmolarity compared to another solution.
In the given questions, the solution in the two arms of the U- tube has the same osmolarity and therefore is isotonic.
