The number of chromosomes 1. Is specific for each type of organism
2. Is the same for every species of organism
3. Decreases from one generation to the next
4. Increases from one generation to the next

The best answer here would be 1.

Explanation:

This really is based off the reproduction of the organism. Asexual reproducing organisms tend to have the same amount of chromosomes, however it is not the same for sexually reproducing organisms.

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive

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
