Answer:
divergent boundary
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust.

In contrast to vinyl, which is lightweight and can be affixed directly to the framing, stone and brick need support when used as external siding.
<h3>Why do people frame works of art?</h3>
The way we experience art can be greatly influenced by the frames. They can be crucial in safeguarding the artwork in addition to improving how it looks. Some frames may even increase the value of the art that is displayed inside them.
<h3>What Is a Frame?</h3>
Art that has been framed has been mounted inside of a picture frame, usually behind glass. Fine art, art prints, antique posters, photographs, or any other piece of artwork can be protected against UV rays, water, dust, and scratches by framing.
<h3>Describe framing.</h3>
The arrangement of visual components in an image or layout in relation to the primary subject is known as visual framing.

Answer:
Advanced forms of life existed on earth at least 3.55 billion years ago. In rocks of that age, fossilized imprints have been found of bacteria that look uncannily like cyanobacteria, the most highly evolved photosynthetic organisms present in the world today. Carbon deposits enriched in the lighter carbon-12 isotope over the heavier carbon-13 isotope-a sign of biological carbon assimilation-attest to an even older age. On the other hand, it is believed that our young planet, still in the throes of volcanic eruptions and battered by falling comets and asteroids, remained inhospitable to life for about half a billion years after its birth, together with the rest of the solar system, some 4.55 billion years ago. This leaves a window of perhaps 200-300 million years for the appearance of life on earth.
divine interventionThis duration was once considered too short for the emergence of something as complex as a living cell. Hence suggestions were made that germs of life may have come to earth from outer space with cometary dust or even, as proposed by Francis Crick of DNA double-helix fame, on a spaceship sent out by some distant civilization. No evidence in support of these proposals has yet been obtained. Meanwhile the reason for making them has largely disappeared. It is now generally agreed that if life arose spontaneously by natural processes-a necessary assumption if we wish to remain within the realm of science-it must have arisen fairly quickly, more in a matter of millennia or centuries, perhaps even less, than in millions of years. Even if life came from elsewhere, we would still have to account for its first development. Thus we might as well assume that life started on earth.
How this momentous event happened is still highly conjectural, though no longer purely speculative. The clues come from the earth, from outer space, from laboratory experiments, and, especially, from life itself. The history of life on earth is written in the cells and molecules of existing organisms. Thanks to the advances of cell biology, biochemistry and molecular biology, scientists are becoming increasingly adept at reading the text.
An important rule in this exercise is to reconstruct the earliest events in life's history without assuming they proceeded with the benefit of foresight. Every step must be accounted for in terms of antecedent and concomitant events. Each must stand on its own and cannot be viewed as a preparation for things to come. Any hint of teleology must be avoided.
Answer:
The correct answer is option B. exocytosis.
Explanation:
Exocytosis is a process that helps in transport secretory products to the plasma membrane through the cytoplasm in a cell. In this process, the materials are transported out of the cell with the help of vesicles.
Some of the examples of the exocytosis are the secretion of the enzymes, proteins, peptide hormones and antibodies from the cell linings of the stomach that help in the digestive process.
Thus, the correct answer is option B. exocytosis.
