A scientist studies the DNA of three different species. The DNA from species A is more similar to DNA from species B than DNA from species C. Which species are probably the most closely related? Explain your answer.

Answers

DNA A and B are probably the most closely related because cells get DNA from the parent cells therefor similar DNA comes from relatives.

Where do clouds form

Answers

Answer:

Clouds generally form within the troposphere.

Explanation:

A cloud is a mass of water droplets, ice crystals or both at the same time, which remains in suspension in the atmosphere, and whose formation is due to the condensation of water vapor in the sky.

Clouds form when the air is saturated and can no longer contain water vapor, this can happen in two ways:

1. The amount of water in the air has increased.

2. The air cools to its dew point.

Clouds generally form within the troposphere.

Weather occurs in the Earths troposphere. So in fact, most clouds are formed there.

Why does air have different pressures

Answers

Because, at lower elevation, everything is tightly packed, and theres more air. As for at higher elevation (like for example at the top of mount everest) There is less air... The higher the elevation, the less air.

The number of valence electrons in each atom of an element affects the elements

Answers

Explanation:

The number of valence electrons or outermost electrons present in an atom determines the chemical properties of an atom.

Therefore, atoms belonging to same group have same number of valence electrons. Thus, atoms of a group have similar chemical properties.

Hence, we can conclude that the number of valence electrons in each atom of an element affects the elements chemical properties.

The number of electrons in an atom's outermost valence shell governs its chemical properties. Elements react to form a closed shell, corresponding to the electron configuration s2p6 . This tendency is called the octet rule, because the atoms have eight valence electrons.

Determine the total mass of ethanol produced when 279. Grams of glucose rescts completely to form ethanol and 132 grams of carbon dioxide.

Answers

The two main postulates that was given by Antoine Lavoisier are, oxygen play an important role in combustion and the other is mass of the reactant and product is conserved. The mass of ethanol is 147gram.

What is law of conservation of mass?

According to Law of conservation of mass, mass can neither be created nor be destroyed. Mass can only be transformed from one form to another. The law of conservation of mass was given by Antoine Lavoisier. Every reaction in nature follow the law given by Antoine Lavoisier that is mass is always conserved.
