Unoxygenated blood from veins enters the right atrium then it goes down to the right ventricle then out through the pulmonary artery to the lungs where it becomes oxygenated blood which then enters the heart through the pulmonary veins and it goes to the left atrium and then is pumped down to the left ventricle and out through the aorta to the arteries where it travels to different organs and becomes deoxygenated and then the cycle repeats itself.
Heyy :))
The best answer would be:

I hope this helps!
Good day :D</span>
Coefficients of Absorption for Common Materials
Perforated acoustic ceiling material 60%
Heavy curtains 50%
Carpeting 20%
Wood 5%
Plaster 3%
Clay tile 3%
Concrete 2%
The answer is C. Heavy curtains
A hypotonic solution<em /> would cause the bacterial cell to lyse or burst. This happens via osmosis. When the concentration of solutes is higher inside the cell, water will move towards that higher concentration because it tries to balance things out. When a lot of water gets into the cell and it can no longer handle it anymore, it will burst or lyse.
<h2>Co-evolution </h2>
Explanation:
A series of reciprocal adaptations in predator and prey populations describes co-dependence or co-evolution
- In co-evolution, two species which are in association evolve together due to their relationship
- Both the species have different ancestry
- Interactions exhibited by co-evolution are: host parasite interaction, prey predator association, evolution of long proboscis in insects for taking nectar from flowers
- Predation is a very short term behavior in which two different species interact with each other for the demand of energy, one is prey and the other is predator
- For successful predation, predator wants minimum energy investment and maximum energy
- Increase in prey population in any given area attracts predator population, hence population of predator also increases in that area
- Increase in predator population results in decrease in prey population after some time decrease in prey population leads to decrease in predator population also
