Well it helped the animals and humans grow the population.
Answer: c. nephron
Explanation: The nephron is the functional unit of the kidney, which actively filters blood and generates urine. The nephron is made of the renal corpuscle and renal tubule. Cortical nephrons are located within the renal cortex, whilst juxtamedullary nephrons are observed inside the renal cortex near the renal medulla.
The SECOND graph represents selection that may lead to reduced variation. It is an example of stabilizing selection.
<h3>What is Stabilizing selection? </h3>
Stabilizing selection is a type of natural selection that leads to a decrease in the genetic variation of the population.
In Stabilizing selection, natural selection tends to favor an average phenotype and then can remove (select) extreme variations.
Stabilizing selection generates a modified bell curve graph in which the central portion is narrower and it is taller than the normal distribution bell shape.

Answer:
Nutrients
Explanation:
The oxygen gotten from the respiratory system through inhalation combines with the glucose gotten from the food we eat (digestive system) to create nutrients for the body (circulatory system).
The oxygen from the inhalation helps in the cellular breakdown of food particles which results in the production of glucose which is a form of nutrients needed by the body for its daily activities.
These are 3 ways that these three systems work together
