Feelings of hunger can be stimulated by the hormone Ghrelin, but suppressed by the hormone PYY.
Ghrelin stimulated the Feelings of hunger and PYY suppresses the feeling of hunger.
Ghrelin is produced in the stomach and sends commands and signals to your brain to eat when we are hungry. It is produced in small amounts in our Pancreas and small intestine both involved in the digestive system of the body.
PYY or Peptide YY is a hormone that is responsible to suppress the feeling of hunger or appetite.
In the people suffering from obesity, the level of PYY is a little less due to there increased appetite. These are involved in the network of the pathways in the regulation of the human's body weight. These are called as Hunger hormones sometimes based on their role in the body. They play a huge role in the small and large hunger of the body upon requirement.

Explanation:
We cant really take away the carbon dioxide that is already present in the atmosphere unless with very advanced technologies but we can surely reduce the production level.
The production of carbon dioxide is mostly from the burning of fossil fuels and the gas produced by factories or vehicles.
As ourselves, we may not be able to stop the factories from producing gas and burning fuel but there are still something that we can do to help a bit. For example, turn off the electrical appliances when we're not using. This can save electricity thus to reduce the burning of fossil fuels. Or we can also take public transport instead of private vehicles to reduce the amout or carbon dioxide given out.
As the government, they should set up laws to control the gas produced by factories and vehicles, such as examining the gas content.

4A. The chromosome theory of inheritance states that chromosomes are the main carriers of the genetic factors responsible for inheritance.
B. Body cells have two sets of chromosomes while sex cells have one set. Therefore, when two sex cells meet, they form an embryo with two copies of each chromosomes thereby producing a body cell with the exact number of chromosomes. In essence, meiosis maintains the right number of chromosomes of body cells by creating half the number of chromosomes of sex cells.
C. Meiosis.
