As temperature increases, density decreases. This allows a hot air balloon to fly because the air in the balloon is heated which makes the air in the balloon less dense then the air around the balloon. Less dense air goes up and denser air goes down so this is why the balloon fly. The design of the balloon is related to thermal energy because as the temperature rises the balloon expands.

As temperature increases, density decreases. This is because the particles have more energy, and spread out, which causes the density to decrease. When the particles spread out, it can also lead to the object changing states. The same effect is seen when the temperature decreases. The particles slow down, have less energy, and go closer together. When the particles come together, it can also lead to an object changing states.

Shifting biomes could have consequences for the regions in which the shifts occur. Read the two cases below and decide which con
Nata [24]

Answer:

increased risk of wildfires- both

local economy suffers- Case 1

carbon storage decreases - Case 2

agricultural production decreases - Case 1

carbon storage increases -  Case 1

disease vector range changes - Case 2

decreased water availability - Case 1

local economy thrives - Case 2

species range changes - Case 2

Explanation:

Fires are common to  taiga biomes. Owing to the fact that the biome in case 1 changed from an agricultural community to a grassland and subsequently to a desert, agricultural productivity will decrease, the local economy will suffer, water availability is decreased and local economy suffers as a consequence of desertification.

On the other hand, in case 2, the diseases vector range as well as species range changes due to the change in the species of foxes from Artic foxes to red foxes that carry rabies. Carbon storage decreases as the taiga biome acts as a carbon sink. The local economy thrives due to timber production.

Lastly, species range changes both in case 1 and case 2 since there is a loss of species. Species range is the area where a particular species can be found during its lifetime. Certainly, the range of area where species are found changed in cases 1 and 2.

What product do all three reactions in Model 2 have in common?
belka [17]

Answer;

-They all provide water

Explanation;

In reaction A, the reactants are glucose and fructose , and the products are Sucrose and water. This is a condensation reaction, following the combination of two monosaccharides (glucose and fructose) forming a dissaccharide (sucrose) and water.

In reaction B, the reactants are two amino acids, that results to formation of a dipeptide and water; this is also a condensation reaction joining two amino acids monomers, to form a dipeptide and water.

-In reaction C, a monoglyceride combines with a fatty acid to form a diglyceride and water. This is also an example of a condensation reaction that results to formation of a diglyceride and water.

Therefore, the similarity of all the reactions is that they are all condensation reactions, with water as a common product.
