Answer:
c) The mass is the same
Explanation:
According to the Law of Conservation of Mass, the total mass of the reactants in a chemical reaction is always equal to the total mass of the products formed. This means that the total mass of the reactants and the total mass of the products will always be the same.
A black hole collapsed to form the sun; small planetary objects formed; small planetary objects collided with each other to form larger objects.
B.
Most of the dust and gas contracted into a central mass—the Sun; half the mass of the cloud condensed to form Jupiter; asteroids and comets crashed into the sun to form the smaller planets.
C.
A spinning cloud of dust began to compress to form the sun; small planetary objects formed; hydrogen and helium became concentrated in the outer solar system to form the outer planets.
D.
Gravitational force held the newly formed planets around the sun; small planetary objects formed; hydrogen and helium became concentrated in the outer solar system to form the outer planets.
The statement about the formation of the solar system that are true and in a correct order are Gravitational force held the newly formed planets around the sun; small planetary objects formed; hydrogen and helium became concentrated in the outer solar system to form the outer planets. The answer is letter D.
Answer:
its caused by the convection of air masses with differences in densities mainly due to their differences in temperatures.

b. Solutions, colloids, suspensions
c. Colloids, solutions, suspensions
d. Colloids, suspensions, solutions
e. Suspensions, colloids, solutions
The mass of the solution of sugar and water is 120 grams.
Mass is the quantity of matter of a physical body.
The mass of the sugar is given is 20g
The mass of the water is 100 g.
100 + 20 = 120 gram
Thus, the mass of the solution of sugar and water is 120 grams.

Answer:
Explanation:
Overuse of antibiotics leads to bacteria's resistance against our drugs. This is increasing at an alarming rate and the reason is that overuse of antibiotics kills bacteria that lack the "resistance" gene or gene that can help them survive the antibiotics (similar is the case for insects that die to insecticides). But, some bacteria can have random mutations in their gene that can help them survive the antibiotic (similar is the case for some insects that can survive the insecticide), thus the surviving bacteria give rise to next generation of bacteria that are resistant to the given antibiotic (similar to how insects that survive the insecticide give birth to new insects that are resistant to insecticide too). Soon, every generation adds new antibiotic resistant bacteria (or new insecticide resistant insects in the case of insects) which is dangerous for all of life on this planet. Therefore, both are similar in the sense that new generations of these organisms will be resistant to our weapons against them.
