Our liquid outer core is formed by mostly molten metals. Since the metals it is formed by, posess magnetical properties, we can conclude, that the earths liquid core does affect our magnetic field.


Since the highest concentration of metals is in the core, we could say, earth would lack a magnetic field, since only the metal located on the surface, wouldn't be able to do such thing.


Answer:


\boxed{\bf~Option~B~is~correct.}



Hope it helped,


Happy homework/ study/ exam!

Drupady [299]

Answer:

Phylogenetic trees can be described as diagrams which represents the evolutionary histories of organisms. The organisms that share more common traits or functions are more closer to one another in the diagram.

The phylogenetic tree in the above diagram shows that the ancestors of Danes, Chinese and Tibetans carried the regular EPAS1 alleles.

According to the tree, the Chinese are more closer to the Tibetans as they carry the Tibetan EPAS1 alleles which the Danes do not carry.

Answer:

13 - D

14 - D

15 - C

Explanation:

for 13

A molecule is two or more atoms chemically combined

An example would be carbon dioxide which contains the two atoms, carbon and oxygen

Reasons its not the other answers:

Electrons, Protons and Neutrons are all parts of an atom therefore they cannot be classified as molecules.

For 14

Remember an atom is the most basic unit out of the units we are talking about

The answer would be D

Reasons its not the other answers

Water is considered to be a molecules as it contains two or more atoms (hydrogen and oxygen)

Air is considered to be a mixture as it contains oxygen and nitrogen which can be separated

Salt is considered to be a compound because salt is made up of two atoms (chloride and sodium) in which they are held up by an ionic bond

For 15

The answer would be C (III only)

Carbon hydrogen and oxygen all happen to by atoms

Reasons its not other answer choices:

Like stated previously water is considered to be a molecule therefore we can eliminate the other answer choices

Other notes:

Compounds and molecules both are combinations of two or more atoms however they are not to be mixed together

the main difference between compounds and molecules is how they are held together

Compounds are held together by ionic bonds while molecules are help up by covalent bonds

compounds and molecules  are made up of atoms that cannot be separated

Mixtures - A mix of two or more substances that can be separated
