Answer:
It will enable gut enzymes to act on the bolus during digestion.
Explanation:
The acidic presence of HCl (hydrochloric acid) in the gastric juice serves as a stimulus for the intestinal wall to produce secretin.
This hormone will act on the pancreas by stimulating the production of pancreatic juice that will contain <u>enzymes</u> (trypsinogen, amylase, lipases) and <u>HCO3⁻</u> (bicarbonate) salts, which have base composition.
With this composition that will be sent to the duodenum, there will be neutralization of acidic solution coming from the stomach and pH leveling around 8.0 (slightly basic) which is great for the enzymes that work there.
Answer:
B. The spinning motion of Earth.
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
