What is the molecular make-up of a material that would be a good thermal conductor?
Thermal conduction is caused by two different things: Phonon conduction and Electron conduction.
Electrons are thermal conductors because electrons have mass and velocity, ie. they have momentum. Thermal energy can be carried by these electrons. What makes a good thermal conductor through the energy carrying of electrons is good electrical conductor. This is because if the electrons are bouncing all around the inside of the conductor, they are transfering their energy to the molecules/atoms of the conductor and not to the other "side".
More technically, the crystal lattice of the conductor must be free of as many defects as possible, and the lattice atoms must have electrons in the the conduction band.
The other thermal conductor is phonons. Phonons are basically a name we give to the movement of the lattice itself. Think of phonons as waves in a pool. The better the phonon conductivity, the better the thermal conduction. Think of phonons as a rope that is held at noth ends and you whip a wave across it. If there is a lot of tention, the wave will quickly travel to the other side. If it is loose, the wave will travel slowly and maybe not even make it to the other side.
The technical equivalent is high bond strengths in the lattice. High bond strength between the atoms means that the phonons will travel faster because the movement of one atom will greatly affect the movement of the neighboring atoms. This is why diamond is such a good thermal conductor, it has very very strong bonds.

What is chemical-makeup?
Chemical makeup refers to the specific elements and compounds that compose a substance or material. It provides information about the types and ratios of atoms present in a substance, which influences its properties and behavior. Understanding the chemical makeup of a material is important in various fields, including chemistry, materials science, and medicine.
How does the zygote's genetics makeup compare to the genetic makeup of the parents?
The zygote's genetic makeup is a combination of genetic material from both parents. It inherits half of its genetic material from the egg (ovum) provided by the mother and half from the sperm provided by the father. This combination of genetic material forms a unique set of genes that determine the zygote's characteristics.
What happens to metals as they conduct electricity?
The electrons in a conductor will support the movement of electric current. A conductor is defined as a material with a number of electrons in its makeup that are actually in what is called the conduction band. The conduction band is an energy level where electrons must be to permit conduction in a material. If the minimum energy in the conduction band in a material is such that a lot of electrons in that material are already at or above that level, then these electrons will be available to support current flow. Remember that electron current flow is moving electrons, and it is not about sending an electron into a conductor, like a wire, at one end and getting that same electron out at the other. It is about sending a bunch of them in at one end, and all the electrons already in the conductor move over and a bunch come out the other end. The electrons already in the conduction band within the conductor support current flow in this way.
Does analysing a specific gas by gas chromatography destroy the gas as in turn it into something else or some other gas?
generally no, most common detector used is thermal conductivity which does not change the chemical makeup.
Which parent contributes the most genetically?
Neither, each of the two parents contribute 1/2 of the genetic material.

What material is used in make up bag?
Makeup bags can be made of various materials, including nylon, canvas, leather, PVC, and silicone. The choice of material often depends on the desired style, durability, and functionality of the makeup bag.
Does breaking a rock into pieces cause it to have a different chemical makeup?
no the material stay the same.
Is ripping pants a physical change or a chemical change?
Ripping pants is a physical change because the structure and composition of the fabric do not change at a molecular level. It is a mechanical alteration that does not involve a change in the chemical makeup of the material.

What are the similarities between archaea and eukarya in terms of their genetic makeup and evolutionary history?
Archaea and Eukarya share similarities in their genetic makeup and evolutionary history. Both have complex cellular structures and genetic material enclosed in a nucleus. They also have similar genetic sequences and molecular machinery for DNA replication and protein synthesis. Evolutionarily, they are believed to have diverged from a common ancestor, with archaea being more closely related to eukarya than bacteria.
