/Glands are derived from - Ans-epithelial tissue
/.Cells joined tightly together are characteristic of - Ans-Epithelial tissue
/.Cells are separated by large extracellular space is in - Ans-Connective tissue
/.Blood vessels and nerves are usually located within - Ans-Muscle tissue
/.Most organs are composed of - Ans-Epithelial, muscle, and connective tissues
/.Sweat is secreted by exocrine glands. This means that - Ans-it is secreted into a duct
/.Which of these statements about homeostasis is true? - Ans-Negative feedback
mechanisms act to correct deviations from a normal range within the internal
environment
/.In a negative feedback loop, the effector produces changes that are – Ans
Opposite indirection to the change produced by the initial stimulus
/.A hormone called parathyroid hormone tasked to help raise the blood calcium
concentration. According to the principles of negative feedback, and effective stimulus
for parathyroid hormone secretion would be - Answ-A fall in blood calcium

/.Which of these lipids have regulatory roles in the body?
A) Steroids
B) Prostaglandins
C) Triglycerides
D) both A & B
E) both B & C - Ans-D, Both steroids and prostaglandins
/.The tertiary structure of a protein is directly determined by - Ans-The primary structure
of the protein
/.The type of bond formed between two molecules of water is - Ans-A hydrogen bond
/.The carbon to nitrogen bond that joins amino acids together is called - Ans-A peptide
bond
/.The RNA nucleotide base that pairs with adenine in DNA is - Ans-Uracil
/.If four bases in one DNA strand are A (adenine), G (guanine), C (cytosine), and T
(thymine), the complementary bases in RNA strand made from this region are - Ans-U,
C, G, A
