Text SolutionText solutionverified iconVerified

(d) The common characteristic feature of plant sieve tube and mammalian erythrocyte is the absence of nucleus. Sieve tubes are the component of phloem and do not contain nucleus. Similarly, erythrocytes in mammalian cell also do not posses nucleus. Erythrocytes are the RBCs which helps in gaseous exchange.
Mitochondria is absent in sieve tube cells. Pigment haemoglobin is present in mammalian erythrocytes but not in sieve tube cells. Cell wall is made of cellulose and is present in all plant cells, and thus absent in erythrocytes.

1. Draw the hypothalamic-pituitary-thyroid axis, showing negative feedback control points. 2. A TRH stimulation test involves measuring basal TSH levels and then measuring again after an injection of TRH. This test is often not necessary for thyroid patients, but would it be beneficial in diagnosing Barbara's condition? (Barbara has low TSH, T3, T4). 3. Extrapolate the knowledge you have of the hypothalamic-anterior-pituitary-thyroid axis to explain how anabolic steroid abuse would lead to testicular atrophy.
