Answer:
c. Compression.
Explanation:
Compression is the primary way from which folded mountains are formed. Fold mountains are created where two or more of tectonic plates of earth are pushed together. Due these collision, compressing boundaries and rocks are folded into rocky hills, mountains, and entire mountain ranges. Fold mountains are formed through a process called orogeny which is an event that leads to both structural deformation of the Earth's lithosphere at the margins of convergent plate.
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
B) It requires energy
D) It involves the help of carrier proteins.
