Oxygen and carbon dioxide travels to and from tiny air sacs in the lungs, through the walls of the capillaries, into the blood. Blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs.

The correct answer is B
The genetic codes language in all living organisms is the same. This is to say that the molecules of life namely DNA and RNA share the same make up in all living things .
There are five types of nucleotides in nature which are the building blocks of RNA and DNA and these are the same in all living organisms . These nucleotides are Adenine, Thymine, Guanine, Cytosine and Uracil.
According to base pairing rules, in all DNA molecules Adenine will always pair with Thymine while Guanine will always pair with Cytosine.
This rule is the same with RNA except that here Thymine is replaced with Uracil. Otherwise the base pairing rule applies in all living organisms, that is to say it is universal.
Answer:
mitochondria DNA (mtDNA) has maternal inheritance
chloroplast DNA (cpDNA) has paternal inheritance
Explanation:
DNA is deoxyribonucleic acid is the molecule responsible for encoding the genetics instructions used in the development and functioning of all known leaving organism.
in humans mitochondria DNA (mtDNA) has maternal inheritance and
chloroplast DNA (cpDNA) has paternal inheritance
