This makes them move faster and further apart and the substance expands. This makes the object's volume increase which changes causes the density to decrease.

When a substance is cooled, the particles lose energy. This makes them move slower and closer together and the substance contracts. This makes the object's volume decrease which changes causes the density to increase.

Explanation:

When an object is heating up its molecules will move faster and expand the object, this means the volume is increasing. Density is equal to mass over volume meaning if the volume is increasing the density will decrease. The opposite is true for when the substance is cooled. Molecules will move slower and the object will contract. The volume will decrease and the density will increase.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
