Answer:
A)Ocean floor evidence of sea floor spreading.
Explanation:
evidence pointing to the steps or process of seafloor spreading and effective plate motion This theory was accepted by many scientist because it depended on hard evidence and could describe most of the modern geological structures such as ocean basins,
What is the tectonic theory?
The theory of plate tectonics plates says that Earth's surface is made of rigid slabs of rock, or plates, that move to each other.

<span>The question says, 'which component of a virus is lacking in a cell. The answer is capsid. virus capsid are protein shell of a virus, they envelope the virus and protect it from harm. Cells does not have capsid, they have rigid cell wall instead. The rigid cell wall protect the cell from harm and also give the cell shape.</span>
Metaphase
At the end of the phase the cell divides into two new cells
Answer:
Bio carbonate ions
Explanation:
The pancreas secrets an aqueous mixture ( water, digestive enzymes and bicarbonate ions) during digestion of food substances from the stomach into the duodenum to begin the process of absorption and assimilation.
The pancreatic duct are lined with duct cells. These are cells which secretes HCO3- ,into the aqueous mixture. This ion is basic. Therefore it neutralizes the acidity of the of the chyme to released from the stomach to enable the pancreatic enzyme to work.
The bicarbonate ions also prevent the walls of the pancreases from getting burnt by the effect if the acidity of the chyme.
Phagocytes are cells that protect the body by ingesting (phagocytosing) harmful foreign particles, bacteria, and dead or dying cells
