True. Ventilation perfusion coupling is the relationship between the amount of air reaching the air sacs of the lungs and the amount of blood reaching the lungs (mechanisms which maintain the correct proportion between alveolar airflow and pulmonary capillary blood flow). The amount of oxygen that reaches the alveoli is the ventilation. The amount of blood that gets to the alveoli is the perfusion. Alveolar ventilation brings oxygen into the lung and removes carbon dioxide. The mixed venous blood brings carbon dioxide into the lung and takes up alveolar oxygen.

Kiko writes a report to compare and contrast the cells of plants and animals. Which of the following statements is accurate and
VladimirAG [237]

Answer:

The correct answer is: Vacuoles in plants are much larger than those in animals.

Explanation:

The cell membrane of animals is not thicker than those in plants. In addition, plant cells have a thick cell wall surrounding the cell membrane that is made of cellulose and provides great protection against osmotic and mechanical stress.

Vacuoles in plants ARE much larger than vacuoles in animals, because plant cells r<u>equire much more water</u> and other substances to function properly. Animals, on the other hand, can ingest water and nutrients through food.

Animal cells DO have chromosomes. Every organism has chromosomes in their cells: prokaryotes have one single circular chromosome, while eukaryotes have many linear chromosomes (humans, for example, have 46 chromosomes).

Plant cells HAVE chloroplasts, as these organelles are crucial, since they participate in the process of photosynthesis - which is fundamental for the nourishment of the plant.

The statement that belongs in Kiko's report is Vacuoles in plants are much larger than those in animals.
