Answer:
Higher risk of developing heart disease
.
Explanation:
The individual can be characterized as healthy person, over weight and under weight. The under weight person has low weight as mentioned in the criteria of the body mass index.
The overweight person feels low and has less energy to do any work. They may also suffer from the anemia condition, and have low nutrition in their body. They cannot develop the risk of the heart disease because heart disease is more common in over weight people.
Thus, the correct answer is option (e).
The process by which molten material moves through the Earth's mantle is known as convection current. This is simply demonstrated within a liquid, in this case molten material, in which the hottest materials rise and the colder materials sink. Convection currents in the mantle are the forces that help move plate tectonics.
Answer:
B
The loss of biodiversity due to deforestation will likely decrease the number of new medicines available in the future
Explanation:
Answer:
The correct answer is A. stabilizing selection
Explanation:
Stabilizing selection is one type of natural selection that occurs when the population having non-extreme traits are stabilized. It results in overexpression of a particular trait in a population. Here most average individual gets selected.
So as the stabilizing selection favors the middle phenotype and not extreme phenotypes it decrease the genetic variation. So here individuals who are having extremely long snout are selected therefore a particular trait is selected and overexpressed in the population. So it is an example of stabilizing selection.
Answer: Combustion is the correct answer.
Explanation:
When a substance combines with oxygen and energy is emitted in the form of heat and light, this process is called combustion.
There are two types of combustion.
1) Complete Combustion : It is a type of combustion in which fuel is quickly react with high amount of oxygen forming carbondioxide, water, heat and light.
2) Incomplete combustion : It is a type of combustion in which fuel is react with low amount of oxygen forming carbonmonoxide, carbon and water.
