The mechanisms of reproductive isolation prevent the reproduction of two individuals from different species. The prezygotic mechanisms disrupt the stages of reproduction before the forming of the zygote or prevent the mating at the start, and the postzygotic mechanisms affect the stages of reproduction after the forming of the zygote.
So, the first and the third example (the urchins and the grasshoppers) show the prezygotic mechanism, as the two individuals are not able to mate or form a zygote.
The second and the fourth example ( zonkey and the death of a zygote) show the working of the postzygotic mechanisms, as the zygote is formed, but it seems to be inviable, and the zonkeys are sterile, preventing the individual to reproduce.
Answer: Alveoli
Explanation: Alveoli of lungs are surrounded by extensive blood capillaries. The partial pressure of oxygen in the alveoli is higher than the blood entering the pulmonary capillaries, hence oxygen moves into the blood. Carbon dioxide in the lungs simultaneously diffuse out of the blood into the alveolar space.
The statement above is TRUE.
Critics' comments are usually acidic and negative in tone. One advantage of paraphrasing such comment is that one has the power to make appropriate word choice that will reduce the attack intensity of such comments.

Oxygen will diffuse from an area of higher concentration (outside the cell) to an area of lower concentration (inside the cell). </span>
Answer:
Cognitive Experience
Explanation:
The process of gathering information, organizing it and using it to adapt to the world is cognitive experience. We collect data and information by understanding it and then try to simplify/interpret in a way that's more organized and easy to understand. When we put this knowledge to the real world by utilizing it, we're using our <em>cognitive experience </em>from the past and applying it to the current situation.
It's like a set of mental procedures which is the way the brain sees, learns, recalls, and thinks about all the details they notice with their five senses.
