Hello, this question is incomplete. The complete question would be:

"The two tubes contain snails and bromothymol blue. After 24 hours, what will the color of the water be in tube B? A. Green (it won't change) B. Yellow C. Blue D. Colorless (clear)"

Answer:

B. Yellow

Explanation:

As you may already know most animals breathe oxygen and exhale carbon dioxide. This is no different in snails. If the carocals were dipped into bromothymol blue-containing cups that allowed the snails to breathe, they would produce a large amount of carbon dioxide in all, within 24 hours. Carbon dioxide causes bromothymol blue to turn yellow due to the chemical reactions that occur between its molecules. So we can say that after 24 hours, the bromothymol blue would turn yellow.

The renal corpuscle consists of a capillary bed called the ____________ and a capsule of epithelial cells.
pychu [463]

The renal corpuscle consists of a capillary bed called the glomerulus and a capsule of epithelial cells. The renal corpuscle is composed of two structures, the glomerulus and the Bowman's capsule. The glomerulus is a small tuft of capillaries containing two cell types. <span>It is also characterized as a cluster of capillaries around the end of a kidney tubule, where waste products are filtered from the blood. Other surfaces that separate body cavities from the outside environment are lined by simple squamous, columnar, or pseudostratified epithelial cells.The gastrointestinal tract, the insides of the lungs, and the reproductive and urinary tracts where other epithelial cells line up make up the exocrine and endocrine glands.</span>
