The most basic concepts of cell theory are that cells are the basic units of life and that all living things are made of cells. Which answer correctly explains why these concepts are the basis of a theory and not a hypothesis? Cell theory explains how cells function rather than predicting how they function.

Cell theory does not change and as a result can be accepted as fact.

Cell theory is a prediction based on observation and not a fully accepted idea.

Cell theory remains largely untested rather than being subject to testing.

the match lol

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave

b. to discover aspects of the natural world.

hopefully i .

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
