Answer:
b. DNA replication occurs only during the G1 phase of the cell cycle.
Explanation:
Anterior Pituitary or adenohypophysis has two parts: pars distalis and pars intermedia..though they are kinda joined in humans.
•Pars distalis (actuallyknown as the anterior pituitary) secretes hormones like Growth Hormone or Somatotrophin, Prolactin, TSH, ACTH,LH,FSH.
•Pars intermedia secretes only one hormone MSH (Melanocyte Stimulating Hormone)
•Posterior pituitary or Neurohypophysis stores two hormones (originally secreted by the hypothalamus) which are Oxytocin and Vasopressin or ADH.
Cheers..dont forget to deem this answer as a brainy answer :)
Answer:
characterized by presence or absence of antigens
the blood types are A, B, O, AB
Explanation:
There are two antigens and two antibodies that are mostly responsible for the ABO types. The specific combination of these four components determines an individual's type in most cases. Erythrocytes and serum were related to the presence of antigens on these erythrocytes and antibodies in the serum. these antigens are A and B, and depending upon which antigen the erythrocytes express, blood either belonged to blood group A or blood group B. A third blood group contained erythrocytes that reacted as if they lacked the properties of A and B, and this group was later called "O" blood group. The fourth blood group AB, was added to the ABO blood group system. These erythrocytes expressed both A and B antigens.
Blood group Antigen present on RBC Antibodies in serum Genotype(s)
A antigen A anti-B AA or AO
B antigen B anti-A BB or BO
AB both A and B antigen none AB
O none anti-A and anti-B OO
