Answer;
-Sea-floor spreading
Sea floor spreading is process that takes place at mid-ocean ridges, evidence is found in magnetic minerals on the ocean floor.
Explanation;
-Seafloor spreading is a geologic process in which tectonic plates; large slabs of Earth's lithosphere; split apart from each other.
-Seafloor spreading and other tectonic activity processes are the result of mantle convection. Mantle convection is the slow, churning motion of Earth’s mantle. Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense.
Explanation:
The capacity of his brain area to take over the functions of the damaged brain areas is known as: Brain plasticity.
The frontal lobe of the brain is associated with the cognitive skills of man. His ability to think, memorize, recognize and decide depends on the frontal lobe responses. Located on the anterior part of the brain, the frontal lobe is more susceptible to injuries. Any injury to frontal lobe disturbs the normal cognitive behaviour and motor abilities. So, the changes in Phineas Gage's behavior indicates that the frontal lobe of his brain got injured.
But he could still lead a normal life with a bit of difficulties in work and behavior. This suggest that the functions of the frontal lobe has been taken over by some other part of the brain.
two unique daughter cells.

Explanation:
Answer:
Trichinella spiralis enter their hosts through ingestion of undercooked pork. When a person consumes raw or undercooked pork that is infected with Trichinella larvae, these larvae can survive in the human digestive system. Once inside the host's body, the larvae develop into adult worms in the small intestine.
Explanation
: To summarize, Trichinella spiralis enter their hosts through the ingestion of undercooked pork.
B. manufacturing nucleotides
C. carrying genetic information
D. giving shape to chromosomes
b. carbohydrates and RNA
c. protein and nucleic acids
d. carbohydrates and nucleic acids
The answer is C.
A virus is made up of or consists of a nucleic acid in varying quantity which may either be RNA or DNA.
The nucleic acid is surrounded by a protein shell called a capsid. The word capsid comes from the Latin word capsa which means box.The capsid and the nucleic acid within it are together referred to as nucleoprotein.The capsid is made up of small sub units called capsomeres.
In many viruses, the nucleoprotein makes up the whole virus. More complex viruses have one or more further enclosing structures also made mostly of protein. These structures are referred to as envelopes and each envelop is specific to a particular virus.
c. protein and nucleic acids
