Consider the cooling curve above. The substance is changing state from a gas to a liquid to a solid. As the temperature changes
Anni [7]

Answer: B)  there is a decrease in kinetic energy and the molecules get closer together.

Explanation: Kinetic energy is directly proportional to temperature, thus as temperature decreases, kinetic energy also decreases.

Gas is the state of matter in which particles are very loosely bound and hence can easily move past one another very easily and have highest kinetic energy.

Liquid is the state of matter in which particles are loosely bound and hence can move past one another easily and have high kinetic energy.

Solid is the state of matter in which particles are tightly bound and hence can not move easily and have low kinetic energy.

Thus on moving from gaseous to solid state, the kinetic energy decreases and the molecules get closer together.

If a father is affected by an X-linked dominant condition and the mother is not, which children can inherit the condition?
kaheart [24]

Answer:

only females

Explanation:

In humans, sex chromosomes in males and females are different. The sex chromosomes found in humans are X and Y chromosomes. X-linked trait is a trait which is inherited on the X- chromosome. According to the question, the trait is passed on a X-linked dominant condition, which means the condition is inherited on the abnormal dominant X-chromosome that will express itself even when in an heterozygous state with a normal X-chromosome.

Hence, a father affected by the condition will have a genotype; XY while a mother that does not have the condition will have a genotype: xx (two normal x chromosomes). Since the Father can only pass his X chromosome to his daughters and never his sons, all his daughters will inherit the condition (see the punnet square in attached image).

N.B: None of the sons will inherit the condition since the mother will pass normal X-chromosomes (x) to her sons.
