Question

35 true or false 2 points
the 2 pathways of circulation are the large intestinal circuit and the systemic circuit.
true
false

36 multiple choice 2 points
the 4 basic tissue types are
epithelial, connective, muscle, neural
connective, muscle, neural, bone
adipose, epithelial, muscle, neural
adipose, mucosal, bone, dendritic

37 multiple choice 2 points
signal amplification is:
characteristic of second messengers
a visual effect perceived by alveoli
when large amounts of ligand produce a small effect on the target
commonly utilized by lipophilic hormones

Explanation:

Evaluate Question 35

The two primary pathways of cardiovascular circulation are the pulmonary circuit and the systemic circuit, not the "large intestinal circuit." Thus, the statement is false.

Evaluate Question 36

The four primary tissue types in the human body are epithelial, connective, muscle, and nervous (neural) tissue. Bone and adipose are specialized subcategories of connective tissue.

Evaluate Question 37

Signal amplification is a key feature of second messenger systems (such as cAMP), where a single ligand binding to a receptor activates multiple G-proteins, which in turn activate many enzymes, leading to a cascade of cellular responses.

Answer:

Question 35

• True
• False (Correct answer)

Question 36
