The Answer is
A. Black box,because black absorbs more heat than white
An example is that on a sunny day you were wearing a black t-shirt you would be sweating you bottom off but if you were wearing a white t-shirt you would be less hot and not sweating your bottom off. Why? Because black absorbs more heat rays than white does
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.
I think the correct answer would be the last option. Monozygotic twins are identical, while dizygotic twins are fraternal. Identical twins involves developing from one zygote where it splits, forming two embryos so that the twins would have more or less the same characteristics. This type of twins can share the same amniotic sac depending on the time the fertilized egg is divided. On the other hand, fraternal twins developed from two eggs wherein they are being fertilized by two different sperm cells resulting to twins which has different characteristics. For this type, the two fertilized eggs would develop separate amniotic sacs.
