Answer the following question given this paragraph: CHAPTER SUMMARY 37.1 Types of Hormones There are three basic types of hormones: lipid-derived, amino acid-derived, and peptide. Lipid-derived hormones are structurally similar to cholesterol and include steroid hormones such as estradiol and testosterone. Amino acid-derived hormones are relatively small molecules and include the adrenal hormones epinephrine and norepinephrine. Peptide hormones are polypeptide chains or proteins and include the pituitary hormones, antidiuretic hormone (vasopressin), and oxytocin. Q: There are three basic types of hormones: lipid-derived, amino acid-derived, and what? Choices: - manipulated - secreted - acidic - peptide A:
(A).
peptide
Ques:Answer the following question given this paragraph: Another amazing feature on the Sun is solar prominences. Plasma flows along the loop that connects sunspots. This plasma forms a glowing arch. The arch is a solar prominence. Solar prominences can reach thousands of kilometers into the Sun's atmosphere. Prominences can last for a day to several months. Prominences can be seen during a total solar eclipse. Q: What is the arch called that forms when plasma of the sun flows along the loop that connects sunspots? Choices: - Energy prominence. - vertical prominence - large prominence - solar prominence A:

Ans:solar prominence
Answer the following question given this paragraph: Q: What phenomenon sometimes causes harmful alleles to become fixed? Choices: - natural selection - competition - spontaneous mutation - genetic drift A:
