Answer:
The oceans are present on the 70 percent of the world but only 5 percent of the total oceans are explored yet.
There are many reasons of this problem but the most important is the hydrostatic pressure.
Hydrostatic pressure can be described as the pressure or weight exerted by the water on the object.
With every increase in 10 meters the pressure increase by 6.47kg (14.27lbs) each square inch of surface.
Due to extreme pressure, oxygen level in the cells of body fluctuates and person becomes unstable and can become unconscious.
Lipase................................
As the left ventricle contracts, oxygenated blood leaves the heart through the aortic valve, into the aorta. The blood to lower limb flows through descending aorta, which continues down to Left Common Femoral Artery, which continues down to Left Superficial Femoral Artery, which continues down to Left Popliteal Artery. The Left Popliteal Artery gives 2 divisions.
1. Left Tibioperoneal Artery (which continues down to the Left Posterior Tibial Artery which supplies back of the foot.)
2. Left Anterior Tibial Artery (which continues down to Left Dorsalis Pedis Artery which continues down to <em>Left First Dorsal Metatarsal Artery</em> which supplies the big toe/first digit of foot.)
The second answer is correct.
If we make a punnet square: (sry if its weird, i had to improvise, lol)
B b -

B - BB - Bb -

b - Bb - bb -
We know that both the female and male are heterozygous, meaning the alleles are different, so one would be dominant, and one would be recessive( for both the female and male). So both female and male would be Bb, as on the punnet square. If we cross them, we get BB, Bb, Bb, and bb. So, 25% of that is BB, which is black feathers. We have 50% of gray feathers, Bb, and 25% white feathers, bb. Therefore, the second option is correct.
