Answer:
The correct answer is the a=heat
Explanation:
Hello! Let's solve this!
Heat is responsible for regulating the temperature on Earth. When the temperature rises, the evaporation of water occurs, so it influences the water cycle. It also influences the climatic phenomena by increasing and lowering the temperature.
The correct answer is the a=heat

Answer: B. It is an ether because it is unable to to form a hydrogen bond, so it is less soluble than water
Explanation: Alcohols
are more soluble in water as they can form hydrogen bonding with water whereas ethers
are less soluble as they do not form hydrogen bonds with water.
For formation of hydrogen bond, the electronegative atom (F, Oand N) must be attached to hydrogen and in ethers (ROR), there is no hydrogen directly attached to electronegative oxygen atom, thus are less soluble in water.
Answer:
Option D = Poor countries often cannot afford investments that ensure access to fresh water.
Explanation:
This question wants to test out knowledge on biodiversity and how the loss of water affects it. Fresh water is needed for plants to grow. Several activities by man such as the use of chemical and fertilizers been washed into the sea, oil spillage and so on causes the pollution of fresh water.
So, because of the great resources (money) of the wealthy countries they have access to good facilities as these countries make use of their money to make sure they are still having access to fresh water despite the pollution caused by man activities.
