<h2>Answer:</h2>
The boiling of water in the iron pan is the activity in which both conduction and convention are used.
<h3>Explanation:</h3>
Energy is transferred from one part of the matter to other part in three ways:
- Conduction
- Convection.
- Radiation.
Conduction is the movement of heat from the collision of the microscopic particles in the matter.
While convection is the transfer from the movement of fluids from one place to another.
In the water boiling activity, the pan is heated by the flame from taking the energy in the collision of atoms in the pan and the energy is transferred into the whole pan and eater molecules. This is conduction while in pan water movement from the bottom to top of pan is by convection.
Hemoglobin is a molecule with a central iron atom responsible for carrying oxygen in your blood cells, as a result, when an oxygen atom bonds to the iron atom, hemoglobin causes the blood to appear bright red (think of it like iron rusting due to exposure to oxygen).
Veins appear blue due to how light reflects off of the various tissues but our blood is NOT blue when it isn't exposed to oxygen.
Arteries have oxygen-rich blood and veins have oxygen-poor blood. Veins carry blood toward the heart and arteries carry blood away from the heart. You can remember this easily because our cells need oxygen and, because arteries carry oxygen-rich blood, they are responsible for carrying blood away from the heart to the different parts of our bodies.
Veins carry the oxygen-depleted blood back toward the heart so it can become oxygen-rich again.
Answer:
- The blood group of the father must be B.
- The genotype of blood group would be
. - The Rh factor of the father can either be positive or negative.
- Thus, the genotype of Rh factor of father would be either Rr or rr.
Rh factor:
The phenotype of the mother Rh factor is positive. Thus, she can have Rr or RR as her genotype as positive is a dominant trait.
If the genotype of the mother is RR then all the offspring would be positive for Rh factor. However, one of the offspring is Rh negative, that means the mother must be heterozygous that is, Rr.
The genotype of the father can either be Rr or rr in order to produce offspring with positive as well as negative Rh.
Blood group:
The blood group of the mother is A. Thus, the genotype can either be 
or 
.
However, the blood groups of the children are O+ and B+.
Thus, the genotype of the mother must be heterozygous that is .
The blood group of the father must be B with genotype in order to produce offspring with blood group O and B.
I totally agree with this one: c:John Roebling—Telephone switchboard. His work is connected with bridges.
