A) pleural, pericardial, and peritoneal cavities B) perithoracic, peritoneal, and pericardial cavities C) thoracic, pleural, and pericardial cavities D) pleural, pericardial, and cardial cavities

The given question is incomplete the complete question is :

In mammals and some reptiles, the coelom is divided into smaller cavities that enclose the lungs, heart, and gut. What are these cavities called?

A. pleural, pericardial, and peritoneal cavities

B. thoracic, pleural, and pericardial cavities

C. pleural, pericardial, and cardial cavities

D. perithoracic, peritoneal, and pericardial cavities

Option A

Explanation:

The intra embryonic coelomic cavity forms within the cavity of the lateral plate in the early development ( week 3 or 4 ). This space undergoes a huge morphological change. It does into changes by folding or partitioning when there is a development of the 3 major cavities in the body.

These cavities are known as pleural , pericardial and peritoneal cavities. The single appearing cavity divides the lateral plate into the splanchnic and somatic mesoderm.

Then the later will be divided into the cavities.

answer; i believe that the correct answer is(d) nondisjunction during meiosis;

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
