It is either b. carbon dioxide or c. oxygen
" Carbon dioxide (CO2<span>) and </span>oxygen<span> (O</span>2<span>) are both molecules that can </span>move<span> across cell membranes through simple diffusion. When you breathe in </span>oxygen<span>, the red blood cells in your lungs have a low concentration of </span>oxygen<span> and a high concentration of carbon dioxide inside. "

Give me the whole question!! im really good at science sis:)
Answer:
If one parent has blood type B and the other parent has blood type O, the percentage of the blood type of the offspring will depend on the genotype of the parent with blood type B.
Explanation:
Knowing the blood type of the offspring of the cross between parents with blood type B and O raises two possible scenarios, depending on whether the genotype of the parent (type B) is B|B or B|O.
Blood type is an inherited trait and is characterized by the presence or absence of surface antigens A and B in the red blood cells, which genetically behave as co-dominant traits.
- <em>Blood type A</em><em> contains antigen A and its genotype can be A|A or A|O.
</em>
- <em>Blood type B </em><em>contains the B antigen, whose genotype can be B|B or B|O.
</em>
- <em>Blood type AB </em><em>contains both antigens and a single A|B genotypic expression.
</em>
- <em>Type O blood lacks surface antigens, and is the recessive trait so its genotype is O|O.</em>
<u>Scenario 1: Parent with genotype B|B.</u>
In this case, knowing that the genotype for type O is always O|O, all offspring would be of blood type B, genotype B|O.
B|B X O|O
Alleles B B
O B|O B|O
O B|O B|O
100% of the offspring would be of blood type B.
<u>Scenario 2: Parent with genotype B|O.</u>
In this case, 50% of the offspring will have blood type O and 50% B.
B|O X O|O
Alleles B O
O B|O O|O
O B|O O|O
In no scenario would offspring of blood type A be possible.
