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

What observations are consistent with the conclusion that DNA serves as the genetic material in eukaryotes? Select the four corr
11111nata11111 [884]

Answer:DNA is shown to be the genetic material in bacteria and some phages.

DNA is shown to be present in mitochondria, chloroplasts and nucleus, where genetic function is performed

Specific genes can be isolated and spliced into bacterial DNA, which can be inserted into a bacterial cell, and then its genetic expression is monitored.

DNA and RNA are found to be the only macromolecules in eukaryotes that consist of a set of subunits which can combine in unique sequence

Explanation:

1. Lipds is another macro molecule with different subnits  of  fatty acids and glycerol,therefore the option ( DNA is found to be the only macro molecule in Eukaryotas that has different sub units) is WRONG.

2 The   correlation of action and absorption spectra varies with different organisms DNA. e..g  in viral cells  there is a wide difference between the absorption and action spectra, that is no correlation, while  some bacterial cells showed correlations. The option(For DNA, content in various cell types action and absorption spectra of ultraviolet light are correlated IS WRONG.
