Occurs when a clot has developed in a coronary vessel and blocks the flow of blood to the heart.

The correct answer will be- Heart Attack

Explanation:

Coronary vessels like coronary arteries supply the oxygen to the heart muscle cells as they also require oxygen to perform their function.

In conditions when the cholesterol or fat or other substances gets accumulated in the coronary arteries forms a plaque in the artery.

The formation of plaque leads to the formation of the blood clot which reduces the blood flow to the heart. Due to this, the heart cells do not get enough amount of oxygen as a result of which the heart cells die.

This condition of death of heart cells is known as the Heart attack caused due to the blood clot formation.

Thus, Heart Attack is the correct answer.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
