Insulin, secreted by pancreatic beta cells, lowers blood glucose by facilitating glucose transport into muscle and adipose cells (via GLUT4 translocation) and promoting glycogenesis in liver and muscle. It also stimulates lipogenesis and protein synthesis, shifting metabolism toward storage/anabolism after meals. In contrast, glucagon (A) from alpha cells raises blood glucose by stimulating glycogenolysis and gluconeogenesis. Epinephrine (D) from the adrenal medulla and cortisol (B) from the adrenal cortex are counter-regulatory hormones that increase blood glucose availability during stress—epinephrine acutely via glycogenolysis and cortisol chronically via gluconeogenesis and proteolysis. TEAS emphasizes homeostatic balance: insulin lowers glucose; glucagon and stress hormones raise it. Clinical connection: in diabetes mellitus (insulin deficiency/resistance), glucose remains elevated, producing polyuria, polydipsia, and risk for long-term vascular complications.

Low serum Ca²⁺ triggers PTH release from the parathyroid glands. PTH acts at bone (indirectly via osteoblast signaling) to increase osteoclast activity, mobilizing calcium; at the kidney to increase Ca²⁺ reabsorption (distal nephron) and decrease phosphate reabsorption (to prevent Ca-phosphate precipitation); and in the kidney to stimulate 1α-hydroxylase, converting vitamin D to its active form (calcitriol), which increases intestinal Ca²⁺ absorption. Therefore, B accurately summarizes the integrated response restoring calcium toward normal. Option A reverses calcitonin’s role—calcitonin tends to decrease osteoclast activity, lowering calcium (a minor effect in adult humans). C is the opposite of PTH physiology (it increases, not decreases, vitamin D activation; it decreases, not increases, phosphate reabsorption). D confuses endocrine axes; ADH regulates water balance via aquaporins, not calcium handling. TEAS frequently assesses homeostatic loops: PTH raises Ca²⁺; calcitonin lowers it; vitamin D enhances GI absorption. Recognizing these coordinated adjustments across bone, kidney, and gut helps connect lab patterns (e.g., hypocalcemia with low PTH vs secondary hyperparathyroidism) to underlying physiology and clinical presentation (tetany, paresthesias, or bone changes).

TEAS Reading asks you to anchor conclusions in explicit text rather than assumptions. The flyer lists clear eligibility (age ≥17, weight ≥110 lb), documentation (photo ID), preparation (eat beforehand), time window (10:00–3:00), and a firm last check-in at 2:30 p.m. plus walk-ins welcome. Option B satisfies every stated condition: the student is ≥110 lb, arrives by 2:20 p.m. (before the 2:30 cut-off), brings ID, and ate, which the notice recommends. Option A contradicts the age rule—no exception is stated for parental consent, so we cannot assume one. Option C ignores “walk-ins welcome,” which specifically says appointments are not required. Option D conflicts with the explicit cut-off time; while the event runs to 3:00 p.m., check-in stops at 2:30 p.m. A reliable TEAS strategy is to convert each bullet into a checklist and test choices item by item. If an answer adds conditions the text does not provide (e.g., parental consent) or alters a numeric boundary (e.g., last check-in), it is not the best-supported inference.

The Golgi apparatus receives proteins and lipids from the rough ER, then modifies (e.g., glycosylation), sorts, and packages them into vesicles for delivery to the plasma membrane, lysosomes, or secretion—making B correct. Ribosomes (A) perform protein synthesis, not packaging; secretory proteins begin translation in the cytosol and are routed to the rough ER via signal peptides, then pass to the Golgi. Lysosomes (C) contain hydrolytic enzymes for intracellular digestion and recycling; ATP production occurs primarily in mitochondria through the citric acid cycle and electron transport chain. The smooth ER (D) synthesizes lipids (steroids, phospholipids), detoxifies drugs, and stores Ca²⁺ (especially in muscle as sarcoplasmic reticulum); DNA transcription occurs in the nucleus. TEAS commonly tests these pairings because they underpin secretory pathways: RER → Golgi → vesicles → exocytosis. Misattributing energy production to lysosomes or transcription to ER reflects common distractors—always map location to process: nucleus (genes/transcription), cytosolic ribosomes (cytosolic proteins), RER (secreted/membrane proteins), Golgi (post-translational processing/trafficking), mitochondria (ATP).

First find area: (12 \times 15 = 180\ \text{ft}^2), so 180 tiles. Add 10% for waste: (180 \times 0.10 = 18) extra tiles; (180 + 18 = 198) tiles total. Tiles come in boxes of 10, so divide and round up to ensure enough material: (198 \div 10 = 19.8) boxes → 20 boxes. Choice C is correct. Choice B (19) incorrectly rounds down and would provide only 190 tiles (short by 8). Choice A (18) assumes 180 tiles and ignores waste. Choice D (21) overshoots—useful only if accounting for breakage beyond 10%. TEAS word problems often require a ceiling step when discrete items are packaged (pills per bottle, tiles per box): even if the computation yields a fraction, you cannot buy part of a box. A quick check: 20 boxes × 10 = 200 tiles; 200 – required 198 = 2 tiles spare—reasonable contingency.
