Answer:
I will give a hypothesis. Just like a tree, when you cut a tree by its trunk, you will the rings. The rings around it represents the tree's age. So when you cut rock, the pores in the rock determine whether it is an old rock or a fossil rock.
Explanation:
The reason is, if it is limestone and it is an old rock, the pores will be slightly big and if the limestone is a fossil rock, then the pores will be bigger due to leaching or denaturing of the minerals in the rock through the ages.
Answer:
C
Explanation:
The gravity of the sun and moon pull on the water of the oceans of the earth hence causing a bulge of these waters at the point on earth where the moon is above. The region where the moon is above, and the opposite side on the earth, will therefore experience high tides while the places at right angles (on the surface of the earth in relation to the moon position) will experience low tides.
Antibodies are produced when the body is exposed to antigens.
During an initial encounter with a foreign antigen, the body's immune system namely the adaptive arm of the immune system, produces memory cells, a group of special lymphocytes that retain and store memory of the antigen.
On a second encounter with the same kind of antigen, the immune system "remembers" the antigen and mounts a rapid, specific and vigorous immune response against the antigen. This response includes the production of massive amounts of antibodies very specific to the antigen.
The antibodies effectively neutralize the antigen and facilitate its destruction.
