Question

select the correct answer. sam is a rancher who owns a herd of cows. how will he be able to identify the effects of toxicity in the herd? a. if one cow becomes ill b. if he finds locoweed growing in the pasture c. if a number of cows become ill d. if the cows are making a noise e. if the cows are grazing in one corner of the pasture

Explanation:

Toxicity in a herd typically affects multiple animals exposed to the same toxic source (e.g., contaminated feed/pasture). A single ill cow (A) could be due to isolated causes, while locoweed presence (B) is a potential source but not direct evidence of toxicity effects. Noise (D) or grazing location (E) are unrelated to toxicity symptoms. Multiple ill cows (C) indicate a shared issue like toxicity.

Answer:

C. if a number of cows become ill
