Answer:
69.7%
Explanation:
Adenine base pairs with thymine
guanine base pairs with cytosine
you need to get to 100%
30.3-100=69.7%
There will be 30.3% or adenine and thymine and 69.7% or guanine and cytosine.
Answer:
Bicarbonate ion, HCO3- (which has a similar charge to chloride ions) also follow sodium ions into the blood. Also, potassium ions, K+ are transported into the nephron so some chloride ions and bicarbonate ions remains in the nephron to balance the charge.
Explanation:
Sodium is the primary positively charged electrolyte in extracellular fluid. Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride. Water is also reabsorbed in order to balance osmotic pressure
When sodium ions are reabsorbed into the blood, few of the substances that are transported with Na+ on the membrane facing the lumen of the tubules include Cl- ions, Ca2+ ions, amino acids, and glucose. Sodium is actively exchanged for K+ using ATP on the basal membrane.
In the distal convoluted tubule, K+ and H+ ions are selectively secreted into the filtrate, while Na+, Cl-, and HCO3- ions are reabsorbed to maintain pH and electrolyte balance in the blood.
Some chloride ions remains in the nephron to balance the charge of the secreted K+ ions and also due to the bicarbonate ions that are removed.

The overwhelming amount of seismic activity particularly happens along convergent plate boundaries. In particular, reverse or thrust faults occurs on convergent plate boundaries.Converging plate boundaries are classified into two types of activities.First is the subduction boundary where the oceanic lithosphere is pressured beneath a continental plate or oceanic plate thus it overrides the other plate then slowly directed to the mantle where it will become a magma. Second is the collisional boundary where earthquakes occur because of the continental crust squeezed together then plates are pushed upwards.Reverse faults are correlated to earthquakes with magnitude of 8 or more.Hence, earthquakes of magnitude 8 or more are considered powerful and mega thrust earthquakes.</span>
Sound cannot travel through a vacuum. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.
