The repair of the coronary vessel is called; Angioplasty

Coronary vessels or arteries are defined as the blood vessels that supply oxygen-rich blood to the heart muscle in order to keep it pumping.

Now when there is a damage to the coronary vessel, it is repaired by a procedure called Angioplasty. This procedure is used to open blocked coronary arteries caused by coronary artery disease.

Angioplasty restores blood flow to the heart muscle without open-heart surgery and can be done in an emergency setting such as a heart attack.

Most transmembrane proteins have hydrophilic regions facing the intra- and extracellular fluid, and hydrophobic regions embedded in the phospholipid bilayer.

Transmembrane proteins are membrane proteins that surrounds the entire entity of the cell connecting both the outside and the inside of the cell.

The hydrophilic regions are the regions that are water loving which faces the intra- and extracellular fluid.

The hydrophobic regions are the regions that repels water and they are found within the phospholipid bilayer.

The first person to classify organisms into two groups was Aristotle, but Lineu was recognized as the father of taxomy

One of the central figures in the history of biological classification was the Swedish naturalist Carl von Linné, popularly known in our country as Linnaeus (1707-1778). His classification system encompassed all organisms and was based on the similarities between them.

Moreover, Aristotle, as far as is known, was the first to classify living beings. He divided them into two groups: animals and plants.

Answer:

A

Explanation:

a - What happens when organisms don't decompose? If there were no decomposers, wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients.

b - What happens when a catastrophic mass extinction occurs? A mass extinction event is when species vanish much faster than they are replaced. This is usually defined as about 75% of the world's species being lost in a 'short' amount of geological time - less than 2.8 million years

c - What does the shifting of tectonic plates cause? At the “seams” where tectonic plates come in contact, the crustal rocks may grind violently against each other, causing earthquakes and volcano eruptions. The relatively fast movement of the tectonic plates under California explains the frequent earthquakes that occur there.

d - Volcanic ash doesn't actually do that.

Now, how do fossil fuels form? After millions of years underground, the compounds that make up plankton and plants turn into fossil fuels. Fossil fuels are formed when the organic matter that has been buried deep within the earth is subject to heat and pressure over millions of years. In both cases, heat and pressure are critical to the formation of fossil fuels.

The cells were first discovered when a scientist named Robert Hooke observed cell walls in cork under a microscope.

Robert Hooke's observation made it possible to visualize the dead cell walls of cork, even without knowing what the image represented, exactly, and without relating living beings to a cellular composition.

In the beginning, the cell theory was elaborated by the scientist Robert Hooke, in the year 1665. Based on this research, the cell is a morphophysiological unit of all living beings, that is, it corresponds to the smallest unit of life.
