Answer:
Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through. Extensive blood supply - ensuring oxygen rich blood is taken away from the lungs and carbon dioxide rich blood is taken to the lungs.
Thermal energy is transferred during heating.
What is thermal energy?
- Thermal energy refers to the ability to do work. As such thermal energy can also be defined as the ability of something to do work as a result of the movement of its particles.
- In other words, thermal energy is the energy possessed by an object or body by virtue of the movement of its constituent particles.
- It is the total internal kinetic energy of an object due to the random motion of its atoms and molecules.
- Thermal energy is a type of kinetic energy owing to the fact that it results from the movement of particles. Kinetic energy is the energy possessed by an object due to its motion.
- Thermal energy forms the foundation of the study of heat energy and thermodynamics. It is one of the oldest forms of energy utilized by mankind.
- Its usage existed even before petroleum and nuclear power sources were discovered.

Answer:
4 RW pink hair color
Explanation:
Let the allele for red hair color = R
Let the allele for white hair color = W
Let the allele for blue hair color = b
Since R and W exhibit co dominance it means none of both traits have the tendency or capability to masked the other .
As such individual with RW genotype = PInk hair color
Allele b is recessive and only individuals with the genotype bb exhibit the blue allele
Now; if a cross occurs between a red-haired Mendelian and a white-haired Mendelian
i.e
RR × WW
we have
R R
W RW RW
W RW RW
So we have the following offspring :
4 RW = 4 pink
So theoretically , the possible phenotypes results to 4 RW pink hair color
Answer: B
Explanation: Hope it helps
i believe the answer to be B
